I wanted to give that patch set a shot but could not figure out against what to get it cleanly applied. Could you reveal its baseline or better yet a git branch ready for testing? > Simon Glass (23): > tegra: keyboard: Fix the init order > dm: video: Flush the cache after a puts() > tegra: mmc: Fix comments in the MMC driver init > tegra: dts: Sync up the tegra124 device tree files with Linux > tegra: dts: Sync up nyan-big files with Linux > tegra: gpio: Show the GPIO value for outputs > tegra: pwm: Add a driver for the tegra PWM > tegra: lcd: Merge tegra124-lcd.c into display.c > tegra: Allow driver model to be used for the PWM > tegra: Allow CONFIG_DM_VIDEO to be used as well as CONFIG_LCD > tegra: nyan-big: Move the LCD driver to driver model > tegra: video: Rename CONFIG_VIDEO_TEGRA to CONFIG_VIDEO_TEGRA20 > tegra: dts: Sync tegra20.dtsi with Linux v4.4 > tegra: video: Merge the display driver into one file > tegra: video: Move the check for CONFIG_OF_CONTROL to Kconfig > tegra: video: Merge the two config structures together > tegra: video: Convert tegra20 LCD driver to driver model > tegra: video: Remove the static variables > tegra: video: Move LCD enums into the driver > tegra: video: Move all fdt-decoding into a single function > tegra: Convert CONFIG_PWM_TEGRA to Kconfig > tegra: video: Move LCD driver to use the DM PWM driver > tegra: video: Clean up the old LCD/PWM driver code > > arch/arm/dts/tegra124-jetson-tk1.dts | 13 + > arch/arm/dts/tegra124-nyan-big.dts | 1676 > ++++++++++++++++++----- > arch/arm/dts/tegra124-nyan.dtsi | 718 ++++++++++ > arch/arm/dts/tegra124-venice2.dts | 14 + > arch/arm/dts/tegra124.dtsi | 693 ++++++++-- > arch/arm/dts/tegra20-colibri.dts | 22 +- > arch/arm/dts/tegra20-harmony.dts | 44 +- > arch/arm/dts/tegra20-medcom-wide.dts | 26 +- > arch/arm/dts/tegra20-paz00.dts | 43 +- > arch/arm/dts/tegra20-plutux.dts | 8 - > arch/arm/dts/tegra20-seaboard.dts | 36 +- > arch/arm/dts/tegra20-tamonten.dtsi | 15 +- > arch/arm/dts/tegra20-tec.dts | 10 +- > arch/arm/dts/tegra20-trimslice.dts | 34 +- > arch/arm/dts/tegra20-ventana.dts | 43 +- > arch/arm/dts/tegra20-whistler.dts | 35 +- > arch/arm/dts/tegra20.dtsi | 541 ++++++-- > arch/arm/include/asm/arch-tegra/dc.h | 5 - > arch/arm/include/asm/arch-tegra/pwm.h | 30 - > arch/arm/include/asm/arch-tegra20/display.h | 108 -- > arch/arm/mach-tegra/Kconfig | 1 + > arch/arm/mach-tegra/Makefile | 1 - > arch/arm/mach-tegra/board2.c | 24 +- > arch/arm/mach-tegra/pwm.c | 89 -- > arch/arm/mach-tegra/tegra20/Makefile | 2 - > arch/arm/mach-tegra/tegra20/display.c | 378 ----- > board/compal/paz00/paz00.c | 2 +- > board/toradex/colibri_t20/colibri_t20.c | 2 +- > configs/colibri_t20_defconfig | 13 +- > configs/harmony_defconfig | 6 + > configs/medcom-wide_defconfig | 6 + > configs/nyan-big_defconfig | 11 +- > configs/paz00_defconfig | 6 + > configs/seaboard_defconfig | 6 + > configs/tec_defconfig | 6 + > configs/ventana_defconfig | 6 + > drivers/gpio/tegra_gpio.c | 5 +- > drivers/input/tegra-kbc.c | 2 +- > drivers/mmc/tegra_mmc.c | 4 +- > drivers/pwm/Kconfig | 9 + > drivers/pwm/Makefile | 3 + > drivers/pwm/tegra_pwm.c | 85 ++ > drivers/video/Kconfig | 10 + > drivers/video/Makefile | 2 +- > drivers/video/simple_panel.c | 1 + > drivers/video/tegra.c | 659 +++++++-- > drivers/video/tegra124/Makefile | 1 - > drivers/video/tegra124/display.c | 184 ++- > drivers/video/tegra124/dp.c | 53 +- > drivers/video/tegra124/sor.c | 162 ++- > drivers/video/tegra124/sor.h | 45 +- > drivers/video/tegra124/tegra124-lcd.c | 95 -- > drivers/video/vidconsole-uclass.c | 1 + > include/configs/colibri_t20.h | 4 - > include/configs/harmony.h | 4 - > include/configs/medcom-wide.h | 4 - > include/configs/nyan-big.h | 3 - > include/configs/paz00.h | 4 - > include/configs/seaboard.h | 4 - > include/configs/tec.h | 4 - > include/configs/tegra-common-post.h | 10 +- > include/configs/ventana.h | 4 - > include/dt-bindings/clock/tegra124-car-common.h | 345 +++++ > include/dt-bindings/clock/tegra124-car.h | 341 +---- > include/dt-bindings/memory/tegra124-mc.h | 31 + > include/dt-bindings/reset/tegra124-car.h | 12 + > include/dt-bindings/thermal/tegra124-soctherm.h | 13 + > include/fdtdec.h | 1 - > lib/fdtdec.c | 1 - > 69 files changed, 4601 insertions(+), 2178 deletions(-) > create mode 100644 arch/arm/dts/tegra124-nyan.dtsi > delete mode 100644 arch/arm/mach-tegra/pwm.c > create mode 100644 drivers/pwm/tegra_pwm.c > delete mode 100644 drivers/video/tegra124/tegra124-lcd.c > create mode 100644 include/dt-bindings/clock/tegra124-car-common.h > create mode 100644 include/dt-bindings/memory/tegra124-mc.h > create mode 100644 include/dt-bindings/reset/tegra124-car.h > create mode 100644 include/dt-bindings/thermal/tegra124-soctherm.h _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de http://lists.denx.de/mailman/listinfo/u-boot
