--------------------------+--------------------------------
Hello all,
Recently I received a router board with MT7620 chip on board.This board is
not an officially listed board but it supports openwrt and pretty much
everything works.But now I need to activate the SDHCI interface.For this,I
have added the following things via the menuconfig of openwrt chaos calmer
source
kmod-mmc
kmod-sdhci
kmod-sdhci-mt7620
and the sdhci part of mt7620.dtsi looks like this
sdhci@10130000 {
compatible = "ralink,mt7620a-sdhci";
reg = <0x10130000 4000>;
interrupt-parent = <&intc>;
interrupts = <14>;
status = "disabled";
};
and my custom made dts(actually copied and modified xiaomi miwifi mini dts
file) file has the following line in it
sdhci@10130000 {
status = "okay";
};
and during boot,I see this message
[ 7.920000] MTK MSDC device init.
[ 7.920000] mtk-sd: MediaTek MT6575 MSDC Driver
[ 7.930000] sdhci: Secure Digital Host Controller Interface driver
[ 7.940000] sdhci: Copyright(c) Pierre Ossman
[ 7.940000] sdhci-pltfm: SDHCI platform and OF driver helper
but when I insert an sd card,nothing happens.No debug message,no mounted
