1) sdmmc on the nanopc-t6 is powered by vcc3v3_sd_s0, not vcc_3v3_s3 add the supply vcc3v3_sd_s0, and control it with gpio4_a5 2) add the card detection property gpio0_a4 3) drop max-frequency = <200000000> as it is already defined in rk3588s.dtsi 4) order no-sdio & no-mmc properties while we are here Signed-off-by: John Clark <inindev@gmail.com> --- .../boot/dts/rockchip/rk3588-nanopc-t6.dts | 27 ++++++++++++++++--- 1 file changed, 23 insertions(+), 4 deletions(-)
