The Amlogic P212 reference design is used by other devices as well, such as (for example) the Khadas VIM boards. Thus this patch adds and moves all common entries from meson-gxl-s905x-p212.dts to a new, separate meson-gxl-s905x-p212.dtsi (which can be re-used on boards such as the Khadas VIM). Support for all boards based on the P212 reference design includes: - enabling IR support - enabling the SAR ADC (SARADC_CH1 is connected to a resistor which indicates the hardware revision, a similar design is found on the Khadas VIM boards) - all MMC controllers (which means that SDIO wifi, the SD card and the eMMC are now supported) - pwm_ef as dependency for the SDIO wifi module - uart_A which is connected to the bluetooth module (the bluetooth module itself is not enabled yet due to missing devicetree bindings for the Broadcom serial bluetooth devices) - uart_AO is moved to the .dtsi (as all known devices use it as their boot-console) Specific to the P212 board: - this also enables the CVBS connector (which is not available on the Khadas VIM boards for example) Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> --- .../boot/dts/amlogic/meson-gxl-s905x-p212.dts | 21 +- .../boot/dts/amlogic/meson-gxl-s905x-p212.dtsi | 214 +++++++++++++++++++++ 2 files changed, 226 insertions(+), 9 deletions(-) create mode 100644 arch/arm64/boot/dts/amlogic/meson-gxl-s905x-p212.dtsi
