Add nodes for eMMC and SD card on sc7280. Signed-off-by: Shaik Sajida Bhanu <sbhanu@xxxxxxxxxxxxxx> --- This change is depends on the below patch series: https://lore.kernel.org/patchwork/cover/1418814/ Changes since V4: - Included gpio header in proper order and moved default pins configs to soc file as suggested by Stephen Boyd. Changes since V3: - Changed pinconfig names as suggested by Konrad Dybcio. - Removed extra lines and aligned some of lines as suggested by Bjorn Andersson. Change since V2: - Added leading zero's for register address and "qcom,sc7280-sdhci" string in compatible as suggested by Stephen Boyd and Doug. - Removed max-frequency flag, no-mmc and no-sdio flags for Sd card as suggested by Doug and Stephen Boyd. - Moved non-removable, no-sd, no-sdio and some pin config changes from soc to board dts file as suggested by Doug. - Removed sleep state for CD line and drive-strength for input pins as suggested by Doug. - Updated bus vote numbers for eMMC and SD card. Changes since V1: - Moved SDHC nodes as suggested by Bjorn Andersson. - Dropped "pinconf-" prefix as suggested by Bjorn Andersson. - Removed extra newlines as suggested by Konrad Dybcio. - Changed sd-cd pin to bias-pull-up in sdc2_off as suggested by Veerabhadrarao Badiganti. - Added bandwidth votes for eMMC and SD card. --- arch/arm64/boot/dts/qcom/sc7280-idp.dts | 71 ++++++++++++ arch/arm64/boot/dts/qcom/sc7280.dtsi | 185 ++++++++++++++++++++++++++++++++ 2 files changed, 256 insertions(+) diff --git a/arch/arm64/boot/dts/qcom/sc7280-idp.dts b/arch/arm64/boot/dts/qcom/sc7280-idp.dts index 3900cfc..1be822c 100644 --- a/arch/arm64/boot/dts/qcom/sc7280-idp.dts +++ b/arch/arm64/boot/dts/qcom/sc7280-idp.dts @@ -7,6 +7,7 @@ /dts-v1/;
