Hello,
I am using git://gitorious.org/thierryreding/linux-next.git to boot my
custom board based on iMX6 sololite. My board has SanDisk iNAND 4.51
I/F and wifi module (Marvel SD8797). The latest update of
sdhci-esdhc-imx.c supports DDR50/SDR50/SDR104 and I would like to use
it for my device.
In my .dts file, I have the following settings:
/* WIFI module */
&usdhc2 {
pinctrl-names = "default", "state_100mhz", "state_200mhz";
pinctrl-0 = <&pinctrl_usdhc2_2_default>;
pinctrl-1 = <&pinctrl_usdhc2_3_100mhz>;
pinctrl-2 = <&pinctrl_usdhc2_4_200mhz>;
bus-width = <4>;
status = "okay";
};
/* eMMC module */
&usdhc4 {
pinctrl-names = "default", "state_100mhz", "state_200mhz";
pinctrl-0 = <&pinctrl_usdhc4_2_default>;
pinctrl-1 = <&pinctrl_usdhc4_3_100mhz>;
pinctrl-2 = <&pinctrl_usdhc4_4_200mhz>;
bus-width = <8>;
status = "okay";
compatible = "fsl,imx6sl-usdhc", "fsl,imx6q-usdhc";
reg = <0x0219c000 0x4000>;
};
Then, in my .dtsi file:
usdhc2 {

1. After using the said pinmux settings, the sdhci-esdh-imx controller
wasn't able to configure it correctly due the the group name for the
two port were the same (default, state_100mhz, state_200mhz).
2. Then, I temporarily disabled usdhc4 to test if the driver able to
enable the SDR50 for my wifi. Then, I was getting the following
errors:
[ 1.655024] mmc0: error -110 whilst initialising SDIO card
[ 3.746340] mmc0: error -110 whilst initialising SDIO card
[ 3.818624] mmc0: host doesn't support card's voltages
[ 3.823783] mmc0: error -22 whilst initialising SDIO card
[ 3.901670] mmc0: host doesn't support card's voltages
[ 3.906862] mmc0: error -22 whilst initialising SDIO card
[ 34.307777] mmc0: host doesn't support card's voltages
[ 34.312980] mmc0: error -22 whilst initialising SDIO card
3. Then, I tried the eMMC to see if the driver able to enable the
DDR50. After booting it, the kernel detect the eMMC only in hight
speed mode.
I would like to know if anyone here can help me to figure out how to
enable the DDR50 for my eMMC and SDR50 for my wifi as well.
Regards,
john
