The r8a7793 GOSE board is similar to r8a7791 Koelsch. For those boards an on-board HDMI encoder chip drives an HDMI port and also a LVDS port is available for external LCD panels. Basic testing with modetest seems to work well. The current state of r8a7793 SoC support is improving, however I2C support is still missing. To check if the DU and HDMI drivers and hardware are working this patch simply ties together I2C2 and GPIO3 with the DU and HDMI devices. Once I2C is enabled in upstream for r8a7793 and GOSE then this patch can easily be reworked into something suitable for upstream. Tested on r8a7793 Gose with HDMI hooked up to a Toshiba TV. # modetest -M rcar-du -s 33:1280x720@AR24 Not-yet-Signed-off-by: Magnus Damm --- Built on top of "renesas-devel-20151217v2-v4.4-rc5" arch/arm/boot/dts/r8a7793-gose.dts | 98 ++++++++++++++++++++++++++++++++++++ arch/arm/boot/dts/r8a7793.dtsi | 18 +++++- 2 files changed, 113 insertions(+), 3 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-sh" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html --- 0001/arch/arm/boot/dts/r8a7793-gose.dts +++ work/arch/arm/boot/dts/r8a7793-gose.dts 2015-12-17 11:48:47.880513000 +0900 @@ -31,6 +31,54 @@ device_type = "memory"; reg = <0 0x40000000 0 0x40000000>; }; + + hdmi-out { + compatible = "hdmi-connector"; + type = "a"; + + port { + hdmi_con: endpoint { + remote-endpoint = <&adv7511_out>; + }; + }; + }; + + x2_clk: x2-clock { + compatible = "fixed-clock"; + #clock-cells = <0>; + clock-frequency = <74250000>; + }; + + x13_clk: x13-clock { + compatible = "fixed-clock"; + #clock-cells = <0>; + clock-frequency = <148500000>; + }; +}; + +&du { + pinctrl-0 = <&du_pins>; + pinctrl-names = "default"; + status = "okay"; + + clocks = <&mstp7_clks R8A7793_CLK_DU0>, + <&mstp7_clks R8A7793_CLK_DU1>, + <&mstp7_clks R8A7793_CLK_LVDS0>, + <&x13_clk>, <&x2_clk>; + clock-names = "du.0", "du.1", "lvds.0", + "dclkin.0", "dclkin.1"; + + ports { + port@0 { + endpoint { + remote-endpoint = <&adv7511_in>; + }; + }; + port@1 { + lvds_connector: endpoint { + }; + }; + }; }; &extal_clk { @@ -38,6 +86,16 @@ }; &pfc { + i2c2_pins: i2c2 { + renesas,groups = "i2c2"; + renesas,function = "i2c2"; + }; + + du_pins: du { + renesas,groups = "du_rgb666", "du_sync", "du_disp", "du_clk_out_0"; + renesas,function = "du"; + }; + scif0_pins: serial0 { renesas,groups = "scif0_data_d"; renesas,function = "scif0"; @@ -134,4 +192,44 @@ }; }; }; +}; + +&i2c2 { + pinctrl-0 = <&i2c2_pins>; + pinctrl-names = "default"; + + status = "okay"; + clock-frequency = <100000>; + + hdmi@39 { + compatible = "adi,adv7511w"; + reg = <0x39>; + interrupt-parent = <&gpio3>; + interrupts = <29 IRQ_TYPE_LEVEL_LOW>; + + adi,input-depth = <8>; + adi,input-colorspace = "rgb"; + adi,input-clock = "1x"; + adi,input-style = <1>; + adi,input-justification = "evenly"; + + ports { + #address-cells = <1>; + #size-cells = <0>; + + port@0 { + reg = <0>; + adv7511_in: endpoint { + remote-endpoint = <&du_out_rgb>; + }; + }; + + port@1 { + reg = <1>; + adv7511_out: endpoint { + remote-endpoint = <&hdmi_con>; + }; + }; + }; + }; }; --- 0001/arch/arm/boot/dts/r8a7793.dtsi +++ work/arch/arm/boot/dts/r8a7793.dtsi 2015-12-17 11:50:59.980513000 +0900 @@ -19,6 +19,7 @@ #size-cells = <2>; aliases { + i2c2 = &i2c2; spi0 = &qspi; }; @@ -405,6 +406,17 @@ status = "disabled"; }; + i2c2: i2c@e6530000 { + #address-cells = <1>; + #size-cells = <0>; + compatible = "renesas,i2c-r8a7793"; + reg = <0 0xe6530000 0 0x40>; + interrupts = <0 286 IRQ_TYPE_LEVEL_HIGH>; + clocks = <&mstp9_clks R8A7793_CLK_I2C2>; + power-domains = <&cpg_clocks>; + status = "disabled"; + }; + scif0: serial@e6e60000 { compatible = "renesas,scif-r8a7793", "renesas,scif"; reg = <0 0xe6e60000 0 64>; @@ -820,19 +832,19 @@ reg = <0 0xe6150994 0 4>, <0 0xe61509a4 0 4>; clocks = <&cp_clk>, <&cp_clk>, <&cp_clk>, <&cp_clk>, <&cp_clk>, <&cp_clk>, <&cp_clk>, <&cp_clk>, - <&cpg_clocks R8A7793_CLK_QSPI>; + <&cpg_clocks R8A7793_CLK_QSPI>, <&hp_clk>; #clock-cells = <1>; clock-indices = < R8A7793_CLK_GPIO7 R8A7793_CLK_GPIO6 R8A7793_CLK_GPIO5 R8A7793_CLK_GPIO4 R8A7793_CLK_GPIO3 R8A7793_CLK_GPIO2 R8A7793_CLK_GPIO1 R8A7793_CLK_GPIO0 - R8A7793_CLK_QSPI_MOD + R8A7793_CLK_QSPI_MOD R8A7793_CLK_I2C2 >; clock-output-names = "gpio7", "gpio6", "gpio5", "gpio4", "gpio3", "gpio2", "gpio1", "gpio0", - "qspi_mod"; + "qspi_mod", "i2c2"; }; mstp11_clks: mstp11_clks@e615099c { compatible = "renesas,r8a7793-mstp-clocks", "renesas,cpg-mstp-clocks";
