If anyone has any objections, please let me know. ------------------ From: Judith Mendez [ Upstream commit 6d4441be969bea89bb9702781f5dfb3a8f2a02a4 ] AM62P SK has external 10K pullups on MMC1 DAT1-DAT3 pins [0]. Disable internal pullups on DAT1-DAT3 so that each line has a single pullup source: - with both pullups enabled, the effective parallel resistance on DAT1-3 (~8.33K) drops below the 10K minimum pullup requirement for data lines (per SD Physical Layer Specification) - removing internal pullups makes DAT1-3 match DAT0 10K external pullup so its consistent and within spec - both internal and external pullups enabled equals unnecessary power consumption [0] https://www.ti.com/lit/zip/SPRR487 Fixes: c00504ea42c0 ("arm64: dts: ti: k3-am62p5-sk: Updates for SK EVM") Signed-off-by: Judith Mendez Reviewed-by: Moteen Shah Link: https://patch.msgid.link/20260223233731.2690472-2-jm@ti.com Signed-off-by: Vignesh Raghavendra Signed-off-by: Sasha Levin --- arch/arm64/boot/dts/ti/k3-am62p5-sk.dts | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/arch/arm64/boot/dts/ti/k3-am62p5-sk.dts b/arch/arm64/boot/dts/ti/k3-am62p5-sk.dts index b94093a7a392a..de3a999aab139 100644 --- a/arch/arm64/boot/dts/ti/k3-am62p5-sk.dts +++ b/arch/arm64/boot/dts/ti/k3-am62p5-sk.dts @@ -224,9 +224,9 @@ main_mmc1_pins_default: main-mmc1-default-pins { AM62PX_IOPAD(0x023c, PIN_INPUT, 0) /* (H20) MMC1_CMD */ AM62PX_IOPAD(0x0234, PIN_OUTPUT, 0) /* (J24) MMC1_CLK */ AM62PX_IOPAD(0x0230, PIN_INPUT, 0) /* (H21) MMC1_DAT0 */ - AM62PX_IOPAD(0x022c, PIN_INPUT_PULLUP, 0) /* (H23) MMC1_DAT1 */ - AM62PX_IOPAD(0x0228, PIN_INPUT_PULLUP, 0) /* (H22) MMC1_DAT2 */ - AM62PX_IOPAD(0x0224, PIN_INPUT_PULLUP, 0) /* (H25) MMC1_DAT3 */ + AM62PX_IOPAD(0x022c, PIN_INPUT, 0) /* (H23) MMC1_DAT1 */ + AM62PX_IOPAD(0x0228, PIN_INPUT, 0) /* (H22) MMC1_DAT2 */ + AM62PX_IOPAD(0x0224, PIN_INPUT, 0) /* (H25) MMC1_DAT3 */ AM62PX_IOPAD(0x0240, PIN_INPUT, 0) /* (D23) MMC1_SDCD */ >; bootph-all; -- 2.53.0
