The module uses an I2C RTC to provide the i.MX6 32768 Hz clock, so it's important to keep it enabled. Not doing so results in incorrect timings of watchdog and i.MX6 RTC. The bootloader enables the watchdog, so disabling the clock results in system reboot. [0] The second patch is required for B155v2, which uses a 1366x768 G156XTN01 panel. The 1366 width is not supported by the display pipeline and result in boot hanging without the patch. [1] Patches 3+4 are updating DT bindings for the new board compatible values. Patch 5 adds the board files. Changes since PATCHv1: * https://lore.kernel.org/lkml/20210222171247.97609-1-sebastian.reichel@collabora.com/ * drop patch 5 (applied) * instead of using 'protected-clocks' in RTC node, add fixed-clock node as suggested by Saravana Kannan * rebased to current master (68a32ba14177) Thanks, [0] There has been a discussion for the problem on the mailinglists last year. The discussion died off, when I told people their ideas don't work. I hope using protected-clocks is fine for this usecase. https://lore.kernel.org/linux-clk/20191108170135.9053-1-sebastian.reichel@collabora.com/ [1] I've sent this before as a separate patch in September, but nobody seemed to care. This adds full context for the problem. https://lore.kernel.org/dri-devel/20200910162831.321556-1-sebastian.reichel@collabora.com/ -- Sebastian Sebastian Reichel (5): rtc: m41t80: add support for fixed clock drm/imx: Add 8 pixel alignment fix dt-bindings: vendor-prefixes: add congatec dt-bindings: arm: fsl: add GE B1x5pv2 boards ARM: dts: imx6: Add GE B1x5v2 .../devicetree/bindings/arm/fsl.yaml | 11 + .../devicetree/bindings/rtc/rtc-m41t80.txt | 9 + .../devicetree/bindings/vendor-prefixes.yaml | 2 + arch/arm/boot/dts/Makefile | 5 + arch/arm/boot/dts/imx6dl-b105pv2.dts | 35 + arch/arm/boot/dts/imx6dl-b105v2.dts | 35 + arch/arm/boot/dts/imx6dl-b125pv2.dts | 33 + arch/arm/boot/dts/imx6dl-b125v2.dts | 33 + arch/arm/boot/dts/imx6dl-b155v2.dts | 36 + arch/arm/boot/dts/imx6dl-b1x5pv2.dtsi | 434 ++++++++++++ arch/arm/boot/dts/imx6dl-b1x5v2.dtsi | 61 ++ arch/arm/boot/dts/imx6dl-qmx6.dtsi | 624 ++++++++++++++++++ drivers/gpu/drm/imx/imx-drm-core.c | 19 +- drivers/gpu/drm/imx/imx-ldb.c | 5 + drivers/gpu/drm/imx/ipuv3-crtc.c | 11 +- drivers/gpu/drm/imx/ipuv3-plane.c | 19 +- drivers/gpu/ipu-v3/ipu-dc.c | 5 + drivers/gpu/ipu-v3/ipu-di.c | 7 + drivers/rtc/rtc-m41t80.c | 12 + 19 files changed, 1390 insertions(+), 6 deletions(-) create mode 100644 arch/arm/boot/dts/imx6dl-b105pv2.dts create mode 100644 arch/arm/boot/dts/imx6dl-b105v2.dts create mode 100644 arch/arm/boot/dts/imx6dl-b125pv2.dts create mode 100644 arch/arm/boot/dts/imx6dl-b125v2.dts create mode 100644 arch/arm/boot/dts/imx6dl-b155v2.dts create mode 100644 arch/arm/boot/dts/imx6dl-b1x5pv2.dtsi create mode 100644 arch/arm/boot/dts/imx6dl-b1x5v2.dtsi create mode 100644 arch/arm/boot/dts/imx6dl-qmx6.dtsi -- 2.30.2
