Only one pin configuration will be used when you add DECON support, not two.

You seem to have a bunch of ARMv8.0 cores, for which there is no such thing as a hypervisor virtual timer (this is an ARMv8.1 addition). > + interrupts = <GIC_PPI 13 (GIC_CPU_MASK_SIMPLE(8) | > IRQ_TYPE_LEVEL_LOW)>, > + <GIC_PPI 14 (GIC_CPU_MASK_SIMPLE(8) | IRQ_TYPE_LEVEL_LOW)>, > + <GIC_PPI 11 (GIC_CPU_MASK_SIMPLE(8) | IRQ_TYPE_LEVEL_LOW)>, > + <GIC_PPI 10 (GIC_CPU_MASK_SIMPLE(8) | IRQ_TYPE_LEVEL_LOW)>; > + }; Thanks, M.

Well, if we have both an interrupt and gpio access, why not provide both?

Maybe even set some > default trigger like "heartbeat". There is a front RGB led, but IIRC that is accessed through the S2MU004 MFD using I2C. There's also a rear "ktd2692" flash, which might or might not be controllable using that, will need to check that one. > > > +&serial_2 { > > + status = "okay"; > > +}; > > + > > +&pinctrl_alive { > > + key_volup: key-volup-pins { > > + samsung,pins = "gpa1-5"; > > + samsung,pin-function = <EXYNOS_PIN_FUNC_F>; > > Maybe EXYNOS_PIN_FUNC_EINT is more self-explanatory? Just a > suggestion though. Was wondering about this too, but a quick grep showed that EXYNOS_PIN_FUNC_EINT was not used in any dts, and in fact only used in "drivers/pinctrl/samsung/pinctrl-exynos.c". The one that was used in dts/dtsis is EXYNOS_PIN_FUNC_F. > > > + samsung,pin-pud = <EXYNOS_PIN_PULL_NONE>; > > + samsung,pin-drv = <0>; > > Here and below: please use EXYNOS5420_PIN_DRV_LV1 (means drive level > = 1x).

They are real pins (as in they do something inside the SoC for sure), but don't seem to be used for much. Some dtsis show "AP_JTAG_TRST_N" being on etc0-0. I'm guessing these are some kind of debug pins?

Are you sure it should be UART > baud clock? These are the two clocks, and it's definitely wrong swapped, as it breaks switching baudrates, but PCLK does in fact have PERI_BUS_USER as it's parent. while EXT_UCLK has PERI_UART0_USER as parent. Not sure what is up with it here but it works fine this way but not the other way around. > > > + clock-names = "uart", "clk_uart_baud0"; > > + samsung,uart-fifosize = <64>; > > + status = "disabled"; > > + }; > > + > > + serial_1: serial@13810000 { > > + compatible = "samsung,exynos5433-uart"; > > + reg = <0x13810000 0x100>; > > + interrupts = <GIC_SPI 247 > > IRQ_TYPE_LEVEL_HIGH>; > > + pinctrl-names = "default"; > > + pinctrl-0 = <&uart1_bus>; > > + clocks = <&cmu_peri > > CLK_GOUT_UART1_EXT_UCLK>, > > + <&cmu_peri CLK_GOUT_UART1_PCLK>; > > + clock-names = "uart", "clk_uart_baud0"; > > + samsung,uart-fifosize = <256>; > > + status = "disabled"; > > + }; > > + > > + serial_2: serial@13820000 { > > + compatible = "samsung,exynos5433-uart"; > > + reg = <0x13820000 0x100>; > > + interrupts = <GIC_SPI 279 > > IRQ_TYPE_LEVEL_HIGH>; > > + pinctrl-names = "default"; > > + pinctrl-0 = <&uart2_bus>; > > + clocks = <&cmu_peri > > CLK_GOUT_UART2_EXT_UCLK>, > > + <&cmu_peri CLK_GOUT_UART2_PCLK>; > > + clock-names = "uart", "clk_uart_baud0"; > > + samsung,uart-fifosize = <256>; > > + status = "disabled"; > > + }; > > + > > + i2c_0: i2c@13830000 { > > + compatible = "samsung,s3c2440-i2c"; > > + reg = <0x13830000 0x100>; > > + interrupts = <GIC_SPI 248 > > IRQ_TYPE_LEVEL_HIGH>; > > + #address-cells = <1>; > > + #size-cells = <0>; > > + pinctrl-names = "default"; > > + pinctrl-0 = <&i2c0_bus>; > > + clocks = <&cmu_peri CLK_GOUT_I2C0_PCLK>; > > + clock-names = "i2c"; > > + status = "disabled"; > > + }; > > + > > + i2c_1: i2c@13840000 { > > + compatible = "samsung,s3c2440-i2c"; > > + reg = <0x13840000 0x100>; > > + interrupts = <GIC_SPI 249 > > IRQ_TYPE_LEVEL_HIGH>; > > + #address-cells = <1>; > > + #size-cells = <0>; > > + pinctrl-names = "default"; > > + pinctrl-0 = <&i2c1_bus>; > > + clocks = <&cmu_peri CLK_GOUT_I2C1_PCLK>; > > + clock-names = "i2c"; > > + status = "disabled"; > > + }; > > + > > + i2c_2: i2c@13850000 { > > + compatible = "samsung,s3c2440-i2c"; > > + reg = <0x13850000 0x100>; > > + interrupts = <GIC_SPI 250 > > IRQ_TYPE_LEVEL_HIGH>; > > + #address-cells = <1>; > > + #size-cells = <0>; > > + pinctrl-names = "default"; > > + pinctrl-0 = <&i2c2_bus>; > > + clocks = <&cmu_peri CLK_GOUT_I2C2_PCLK>; > > + clock-names = "i2c"; > > + status = "disabled"; > > + }; > > + > > + i2c_3: i2c@13860000 { > > + compatible = "samsung,s3c2440-i2c"; > > + reg = <0x13860000 0x100>; > > + interrupts = <GIC_SPI 251 > > IRQ_TYPE_LEVEL_HIGH>; > > + #address-cells = <1>; > > + #size-cells = <0>; > > + pinctrl-names = "default"; > > + pinctrl-0 = <&i2c3_bus>; > > + clocks = <&cmu_peri CLK_GOUT_I2C3_PCLK>; > > + clock-names = "i2c"; > > + status = "disabled"; > > + }; > > + > > + i2c_4: i2c@13870000 { > > + compatible = "samsung,s3c2440-i2c"; > > + reg = <0x13870000 0x100>; > > + interrupts = <GIC_SPI 252 > > IRQ_TYPE_LEVEL_HIGH>; > > + #address-cells = <1>; > > + #size-cells = <0>; > > + pinctrl-names = "default"; > > + pinctrl-0 = <&i2c4_bus>; > > + clocks = <&cmu_peri CLK_GOUT_I2C4_PCLK>; > > + clock-names = "i2c"; > > + status = "disabled"; > > + }; > > + > > + i2c_5: i2c@13880000 { > > + compatible = "samsung,s3c2440-i2c"; > > + reg = <0x13880000 0x100>; > > + interrupts = <GIC_SPI 253 > > IRQ_TYPE_LEVEL_HIGH>; > > + #address-cells = <1>; > > + #size-cells = <0>; > > + pinctrl-names = "default"; > > + pinctrl-0 = <&i2c5_bus>; > > + clocks = <&cmu_peri CLK_GOUT_I2C5_PCLK>; > > + clock-names = "i2c"; > > + status = "disabled"; > > + }; > > + > > + i2c_6: i2c@13890000 { > > + compatible = "samsung,s3c2440-i2c"; > > + reg = <0x13890000 0x100>; > > + interrupts = <GIC_SPI 254 > > IRQ_TYPE_LEVEL_HIGH>; > > + #address-cells = <1>; > > + #size-cells = <0>; > > + pinctrl-names = "default"; > > + pinctrl-0 = <&i2c6_bus>; > > + clocks = <&cmu_peri CLK_GOUT_I2C6_PCLK>; > > + clock-names = "i2c"; > > + status = "disabled"; > > + }; > > + > > + i2c_7: i2c@11cd0000 { > > + compatible = "samsung,s3c2440-i2c"; > > + reg = <0x11cd0000 0x100>; > > + interrupts = <GIC_SPI 255 > > IRQ_TYPE_LEVEL_HIGH>; > > + #address-cells = <1>; > > + #size-cells = <0>; > > + pinctrl-names = "default"; > > + pinctrl-0 = <&i2c7_bus>; > > + clocks = <&cmu_peri CLK_GOUT_I2C7_PCLK>; > > + clock-names = "i2c"; > > + status = "disabled"; > > + }; > > + }; > > +}; > > + > > +#include "exynos7885-pinctrl.dtsi" > > +#include "arm/exynos-syscon-restart.dtsi" > > Have you verified both reboot and power off functions from this file? > I guess if some doesn't work, it's better to avoid including this, > but > instead add corresponding sub-nodes into your pmu_sytem_controller. They do in fact work on my phone ;) One thing I noticed is that if I send a poweroff command and hold down the power key, it will stay powered on until I release it. I guess that's just how it's wired up. Sometimes, very rarely a reboot does act weird though: Every once in a while, a reboot turns the phone off, then the bootloader starts outputting on UART before it cuts off my connection to UART by resetting the MUIC, and the phone never powers on again by itself after. (like.. bootloader starts then powers the phone off even before the display would come on?) I should check the bootloader logs saved to a last_kmsg buffer the next time this happens, but this looks like more of a bootloader issue rather than this being wrong. > > > -- > > 2.34.1 > >

No, let's keep them ordered by unit addresses, at least within each group (so within clock controllers, pinctrl nodes etc).

Why open-coding same code work and including would not? Assuming that it compiles, of course. Best regards, Krzysztof

Also not sure if level interrupt is needed for a key, maybe edge type would be better. Also, I still don't understand 0 in the end. Checking existing dts's, most of those only define "gpios". I'd say having only "gpios" is more obvious, and will work the same way. But that's not a strong preference on my side, just think it's a bit misleading right now. > > > > > >> + interrupt-parent = <&gpa1>; > >> + linux,code = <KEY_VOLUMEUP>; > >> + gpios = <&gpa1 5 GPIO_ACTIVE_LOW>; > >> + }; > >> + > >> + voldown-key { > >> + label = "Volume Down"; > >> + interrupts = <6 IRQ_TYPE_LEVEL_HIGH 0>; > >> + interrupt-parent = <&gpa1>; > >> + linux,code = <KEY_VOLUMEDOWN>; > >> + gpios = <&gpa1 6 GPIO_ACTIVE_LOW>; > >> + }; > >> + > >> + power-key { > >> + label = "Power"; > >> + interrupts = <7 IRQ_TYPE_LEVEL_HIGH 0>; > >> + interrupt-parent = <&gpa1>; > >> + linux,code = <KEY_POWER>; > >> + gpios = <&gpa1 7 GPIO_ACTIVE_LOW>; > >> + wakeup-source; > >> + }; > >> + }; > >> +}; > >> + > > > > If there are some LEDs by chance on that board -- it might be useful > > to define those here with "gpio-leds" as well.

One way to implicitly figure that out is to look at nodes like "sd0_clk_fast_slew_rate_3x" and those pin-drv properties. Also, in Exynos850 for most of domains those constants are appropriate, that's why I mentioned that. > > > >> + }; > >> + > >> + key_voldown: key-voldown-pins { > >> + samsung,pins = "gpa1-6"; > >> + samsung,pin-function = <EXYNOS_PIN_FUNC_F>; > >> + samsung,pin-pud = <EXYNOS_PIN_PULL_NONE>; > >> + samsung,pin-drv = <0>; > >> + }; > >> + > >> + key_power: key-power-pins { > >> + samsung,pins = "gpa1-7"; > >> + samsung,pin-function = <EXYNOS_PIN_FUNC_F>; > >> + samsung,pin-pud = <EXYNOS_PIN_PULL_NONE>; > >> + samsung,pin-drv = <0>; > >> + }; > >> +}; > >> diff --git a/arch/arm64/boot/dts/exynos/exynos7885-pinctrl.dtsi b/arch/arm64/boot/dts/exynos/exynos7885-pinctrl.dtsi > >> new file mode 100644 > >> index 000000000000..8336b2e48858 > >> --- /dev/null > >> +++ b/arch/arm64/boot/dts/exynos/exynos7885-pinctrl.dtsi > >> @@ -0,0 +1,865 @@ > >> +// SPDX-License-Identifier: GPL-2.0 > >> +/* > >> + * Samsung Exynos7885 SoC pin-mux and pin-config device tree source > >> + * > >> + * Copyright (c) 2017 Samsung Electronics Co., Ltd. > >> + * Copyright (c) 2021 Dávid Virág > >> + * > >> + * Samsung's Exynos7885 SoC pin-mux and pin-config options are listed as > >> + * device tree nodes in this file. > >> + */ > >> + > >> +#include <dt-bindings/pinctrl/samsung.h> > > > > You probably also need <dt-bindings/interrupt-controller/arm-gic.h> > > here for GIC_SPI definition. > > > >> + > >> +&pinctrl_alive { > >> + etc0: etc0 { > >> + gpio-controller; > >> + #gpio-cells = <2>; > >> + > >> + interrupt-controller; > >> + #interrupt-cells = <2>; > >> + }; > >> + > >> + etc1: etc1 { > >> + gpio-controller; > >> + #gpio-cells = <2>; > >> + > >> + interrupt-controller; > >> + #interrupt-cells = <2>; > >> + }; > > > > Hmm, what are these two?

What do you expect to find in > exynos7885.dtsi for these? Why removing them? etc0 and etc1 nodes are defined as gpio-controller and interrupt-controller. So "compatible" should be provided somewhere for those nodes. For example, for "gpa0" node below you can find its compatible in exynos7885.dtsi. Right now I don't understand how those etc0 and etc1 can be used at all. So maybe it's better to just remove those? Those are not used anywhere and we probably don't even know what those nodes represent. My point is, if those are actually some leftovers from vendor kernel and those are not going to be used (and I don't see how, without "compatible"), then we probablly better off without those. > > > >> + > >> + gpa0: gpa0 { > >> + gpio-controller; > >> + #gpio-cells = <2>; > >> + > >> + interrupt-controller; > >> + #interrupt-cells = <2>; > >> + interrupt-parent = <&gic>; > >> + interrupts = <GIC_SPI 0 IRQ_TYPE_LEVEL_HIGH>, > >> + <GIC_SPI 1 IRQ_TYPE_LEVEL_HIGH>, > >> + <GIC_SPI 2 IRQ_TYPE_LEVEL_HIGH>, > >> + <GIC_SPI 3 IRQ_TYPE_LEVEL_HIGH>, > >> + <GIC_SPI 4 IRQ_TYPE_LEVEL_HIGH>, > >> + <GIC_SPI 5 IRQ_TYPE_LEVEL_HIGH>, > >> + <GIC_SPI 6 IRQ_TYPE_LEVEL_HIGH>, > >> + <GIC_SPI 7 IRQ_TYPE_LEVEL_HIGH>; > >> + }; > >> + > >> + gpa1: gpa1 { > >> + gpio-controller; > >> + #gpio-cells = <2>; > >> + > >> + interrupt-controller; > >> + #interrupt-cells = <3>; > >> + interrupt-parent = <&gic>; > >> + interrupts = <GIC_SPI 8 IRQ_TYPE_LEVEL_HIGH>, > >> + <GIC_SPI 9 IRQ_TYPE_LEVEL_HIGH>, > >> + <GIC_SPI 10 IRQ_TYPE_LEVEL_HIGH>, > >> + <GIC_SPI 11 IRQ_TYPE_LEVEL_HIGH>, > >> + <GIC_SPI 12 IRQ_TYPE_LEVEL_HIGH>, > >> + <GIC_SPI 13 IRQ_TYPE_LEVEL_HIGH>, > >> + <GIC_SPI 14 IRQ_TYPE_LEVEL_HIGH>, > >> + <GIC_SPI 15 IRQ_TYPE_LEVEL_HIGH>; > >> + }; > >> + > >> + gpa2: gpa2 { > >> + gpio-controller; > >> + #gpio-cells = <2>; > >> + > >> + interrupt-controller; > >> + #interrupt-cells = <2>; > >> + }; > >> + > >> + gpq0: gpq0 { > >> + gpio-controller; > >> + #gpio-cells = <2>; > >> + > >> + interrupt-controller; > >> + #interrupt-cells = <2>; > >> + }; > >> + > >> + sim1_det_gpio: sim1-det-gpio-pins { > >> + samsung,pins = "gpa2-5"; > >> + samsung,pin-function = <EXYNOS_PIN_FUNC_F>; > >> + samsung,pin-pud = <EXYNOS_PIN_PULL_NONE>; > >> + }; > >> + > >> + sim0_det_gpio: sim0-det-gpio-pins { > >> + samsung,pins = "gpa2-6"; > >> + samsung,pin-function = <EXYNOS_PIN_FUNC_F>; > >> + samsung,pin-pud = <EXYNOS_PIN_PULL_NONE>; > >> + }; > >> + > >> + speedy_bus: speedy-bus-pins { > >> + samsung,pins = "gpq0-2"; > >> + samsung,pin-function = <EXYNOS_PIN_FUNC_2>; > >> + samsung,pin-con-pdn = <EXYNOS_PIN_PDN_PREV>; > >> + samsung,pin-pud = <EXYNOS_PIN_PULL_UP>; > >> + samsung,pin-drv = <0>; > > > > Here and below: suggest using EXYNOS5420_PIN_DRV_LV* constants.

I don't have the manual but in other SoCs these are not left-overs, but real GPIO banks. Their configurability depends on the SoCs. I agree that usually they are not used (because one of the uses is debugging), but they can be included for completness of HW description. Assuming they exist.

Indeed. That's a bloody -1 returned by the firmware. Quality implementation, as usual... Thanks, M.

Add initial Exynos7885 device tree nodes with dts for the Samsung Galaxy A8 (2018), a.k.a. "jackpotlte", with model number "SM-A530F". Currently this includes some clock support, UART support, and I2C nodes. Signed-off-by: David Virag <virag.david003@gmail.com> --- Changes in v2: - Remove address-cells, and size-cells from dts, since they are already in the dtsi. - Lower case hex in memory node - Fix node names with underscore instead of hyphen - Fix line breaks - Fix "-key" missing from gpio keys node names - Use the form without "key" in gpio key labels on all keys - Suffix pin configuration node names with "-pins" - Remove "fimc_is_mclk" nodes from pinctrl dtsi for now - Use macros for "samsung,pin-con-pdn", and "samsung,pin-con-pdn" - Add comment about Arm PMU - Rename "clock-oscclk" to "osc-clock" - Include exynos-syscon-restart.dtsi instead of rewriting its contents Changes in v3: - Fix typo (seperate -> separate) Changes in v4: - Fixed leading 0x in clock-controller nodes - Actually suffixed pin configuration node names with "-pins" - Seperated Cortex-A53 and Cortex-A73 PMU arch/arm64/boot/dts/exynos/Makefile | 7 +- .../boot/dts/exynos/exynos7885-jackpotlte.dts | 95 ++ .../boot/dts/exynos/exynos7885-pinctrl.dtsi | 865 ++++++++++++++++++ arch/arm64/boot/dts/exynos/exynos7885.dtsi | 438 +++++++++ 4 files changed, 1402 insertions(+), 3 deletions(-) create mode 100644 arch/arm64/boot/dts/exynos/exynos7885-jackpotlte.dts create mode 100644 arch/arm64/boot/dts/exynos/exynos7885-pinctrl.dtsi create mode 100644 arch/arm64/boot/dts/exynos/exynos7885.dtsi
