Allow for reconfiguration of the signaling voltage of SDMMC1 on Tegra210 P2597 and fix SDMMC4 signaling voltage regulator configuration on Tegra210 P2180. This series depends on the "Tegra PMC pinctrl pad configuration" series posted earlier. Changelog: v2: - Change the pinctrl bindings commit title - Use IS_ERR in tegra_sdhci_init_pinctrl_info() - Add nvidia,only-1-8-v property - Disable UHS modes in case the pad and regulator configuration is invalid Aapo Vienamo (10): dt-bindings: mmc: tegra: Add pad voltage control properties dt-bindings: mmc: tegra: Add nvidia,only-1-8-v property mmc: tegra: Reconfigure pad voltages during voltage switching arm64: dts: Add Tegra210 sdmmc pinctrl voltage states arm64: dts: Add Tegra186 sdmmc pinctrl voltage states arm64: dts: tegra210-p2180: Allow ldo2 to go down to 1.8 V arm64: dts: tegra210-p2180: Correct sdmmc4 vqmmc-supply arm64: dts: tegra210-p2597: Remove no-1-8-v from sdmmc1 arm64: dts: tegra210: Add nvidia,only-1-8-v to sdmmc4 arm64: dts: tegra186: Add nvidia,only-1-8-v to sdmmc4 .../bindings/mmc/nvidia,tegra20-sdhci.txt | 24 ++++ arch/arm64/boot/dts/nvidia/tegra186.dtsi | 41 ++++++ arch/arm64/boot/dts/nvidia/tegra210-p2180.dtsi | 12 +- arch/arm64/boot/dts/nvidia/tegra210-p2597.dtsi | 1 - arch/arm64/boot/dts/nvidia/tegra210.dtsi | 28 +++++ drivers/mmc/host/sdhci-tegra.c | 140 +++++++++++++++++++-- 6 files changed, 222 insertions(+), 24 deletions(-) -- 2.7.4
