From 0fe4366c9ac93a9cb4e4515a514ff3492ae47d9c Mon Sep 17 00:00:00 2001 From: Hai Pham Date: Thu, 22 Dec 2022 22:18:01 +0100 Subject: [PATCH] ARM: renesas: condor: switch eMMC bus to 1V8 The eMMC card has two supplies, VCC and VCCQ. The VCC supplies the NAND array and the VCCQ supplies the bus. On Condor, the VCC is connected to 3.3V rail, while the VCCQ is connected to 1.8V rail. Adjust the pinmux to match the bus, which is always operating in 1.8V mode. Based on Linux commit 69efe4bbeda50745 ("arm64: dts: renesas: condor: Switch eMMC bus to 1V8") from Wolfram Sang Signed-off-by: Hai Pham --- arch/arm/dts/r8a77980-condor.dts | 8 +------- 1 file changed, 1 insertion(+), 7 deletions(-) diff --git a/arch/arm/dts/r8a77980-condor.dts b/arch/arm/dts/r8a77980-condor.dts index 3dde028e22..f0a0a51d73 100644 --- a/arch/arm/dts/r8a77980-condor.dts +++ b/arch/arm/dts/r8a77980-condor.dts @@ -212,7 +212,7 @@ &mmc0 { pinctrl-0 = <&mmc_pins>; - pinctrl-1 = <&mmc_pins_uhs>; + pinctrl-1 = <&mmc_pins>; pinctrl-names = "default", "state_uhs"; vmmc-supply = <&d3_3v>; @@ -253,12 +253,6 @@ }; mmc_pins: mmc { - groups = "mmc_data8", "mmc_ctrl", "mmc_ds"; - function = "mmc"; - power-source = <3300>; - }; - - mmc_pins_uhs: mmc_uhs { groups = "mmc_data8", "mmc_ctrl", "mmc_ds"; function = "mmc"; power-source = <1800>;
