Hello Champs,
I'd like to use a CD pin not GPIO to detect SD card.
I.m using 3.14.28 BSP and in the device tree, I changed a following line
cd-gpios = <&gpio2 2 0>;
to
fsl,cd-controller;
Then I added a line MX6QDL_PAD_GPIO_1__SD1_CD_B as follows
pinctrl_usdhc2: usdhc2grp {
fsl,pins = <
MX6QDL_PAD_GPIO_1__SD1_CD_B 0x80000000
Is the value 0x80000000(NO_PAD_CTL) Ok?
Or do I need to set a value like other SD2 pins(0x17059)?
We have this code in drivers/mmc/host/sdhci-esdhc-imx.c
case ESDHC_CD_CONTROLLER:
/* we have a working card_detect back */
host->quirks &= ~SDHCI_QUIRK_BROKEN_CARD_DETECTION;
break;
Dose this code really work?
Best regards,
N.Shinozaki
