I dropped the defconfig patches for now, there is more to them than it seems, and they warrant a separate series and discussion. Also I dropped the MMC binding patch (v1 07/14), since Ulf already applied that. Other than that this tries to clarify the watchdog clock situation in a new patch (02/12), and fixes some smaller issues, as pointed out by Samuel (many thanks for that!). ---------- The Allwinner F1C100 SoC didn't see much love since its initial merge in 2018: the originally submitted .dts files were very basic, and didn't cover such simple peripherals as MMC and SPI. On top of that the watchdog compatible string was wrong, leading to a non-functional watchdog and reset functionality. This series aims to fix that, after the series MMC and SPI work, and make dtbs_check comes back clean. This was tested with mounting a filesystem on /dev/mmcblk0 on a LicheePi Nano, also with accessing the SPI flash through /dev/mtdblock and mtd_debug. Reboot and watchdog now also work. Mainline U-Boot recently gained F1C100 support, and those DT updates are needed there as well to get full MMC and SPI access. The series is structured as follows: - Patches 01/12 and 03/12 fix the watchdog, which allows to properly reboot the system. - Patches 04-07 fix some shortcomings of the existing DT files, to make them DT binding compliant. - Patches 08-09 are Jesse's recent MMC patches, with the comments from the last version addressed [1]. - Patches 10-12 add SPI support, to enable access to the SPI flash on the LicheePi Nano board. Cheers, Andre Changelog v1 ... v2: - drop multi_v5_defconfig patches (v1 13/14 and 14/14) - drop MMC bindings patch (v1 07/14): already applied - dt-binding: move watchdog compatible string among the others - dt-binding: new patch to clarify watchdog clock source - dtsi: add missing @0 to cpu node - add Acks and R-b's - dtsi: fix ordering of SPI nodes (plus typo in commit message) Changelog for the MMC patches [1]: - bindings doc: extend commit message - .dtsi: extend commit message, re-order mmc0_pins node, add drive-strength - .dts: extend commit message, add alias, regulator and disable-wp [1] https://lore.kernel.org/linux-arm-kernel/20220130220325.1983918-1-Mr.Bossman075@gmail.com/ [2] https://lore.kernel.org/linux-usb/20200331170219.267732-1-thirtythreeforty@gmail.com/ Andre Przywara (9): dt-bindings: watchdog: sunxi: fix F1C100s compatible dt-bindings: watchdog: sunxi: clarify clock support ARM: dts: suniv: F1C100: fix watchdog compatible dt-bindings: arm: sunxi: document LicheePi Nano name ARM: dts: suniv: F1C100: fix CPU node ARM: dts: suniv: F1C100: fix timer node dt-bindings: spi: sunxi: document F1C100 controllers ARM: dts: suniv: F1C100: add SPI support ARM: dts: suniv: licheepi-nano: add SPI flash Jesse Taube (3): ARM: dts: suniv: F1C100: add clock and reset macros ARM: dts: suniv: F1C100: add MMC controllers ARM: dts: suniv: licheepi-nano: add microSD card .../devicetree/bindings/arm/sunxi.yaml | 5 + .../bindings/spi/allwinner,sun6i-a31-spi.yaml | 1 + .../watchdog/allwinner,sun4i-a10-wdt.yaml | 24 ++-- .../boot/dts/suniv-f1c100s-licheepi-nano.dts | 31 ++++++ arch/arm/boot/dts/suniv-f1c100s.dtsi | 104 ++++++++++++++++-- 5 files changed, 140 insertions(+), 25 deletions(-)
