Add sdhc instances for supporting eMMC and SD-card on sc7180. The regulators should be in HPM state for proper functionality of eMMC and SD-card. Updating corresponding regulators accordingly. Signed-off-by: Veerabhadrarao Badiganti <vbadigan@xxxxxxxxxxxxxx> --- This depends on the patch series (dt support for sc7180): https://lkml.org/lkml/2019/11/8/149 Also depends on documentation commit 2078158 (Present on mmc-next) Changes since V1: - Updated the regulator min, max voltages as per eMMC/SD-card voltage requirements - Enabled IOMMU for eMMC and SD-card. - Added pull and drive strength to SD-card cd-gpio. - Incorporated review comments by Matthias Kaehlcke. --- arch/arm64/boot/dts/qcom/sc7180-idp.dts | 47 +++++++--- arch/arm64/boot/dts/qcom/sc7180.dtsi | 148 ++++++++++++++++++++++++++++++++ 2 files changed, 183 insertions(+), 12 deletions(-) diff --git a/arch/arm64/boot/dts/qcom/sc7180-idp.dts b/arch/arm64/boot/dts/qcom/sc7180-idp.dts index 189254f..b6d4dc1 100644 --- a/arch/arm64/boot/dts/qcom/sc7180-idp.dts +++ b/arch/arm64/boot/dts/qcom/sc7180-idp.dts @@ -7,6 +7,7 @@ /dts-v1/;
