Hi Folks,
I am trying to set the iodelay for mmc3 via device tree
mmc3_iodelay_manual1_conf {
pinctrl-single,pins = <
0x678 0x182 /* CFG_MMC3_CLK_IN */
0x680 0x25d /* CFG_MMC3_CLK_OUT */
0x684 0x0 /* CFG_MMC3_CMD_IN */
0x688 0x0 /* CFG_MMC3_CMD_OEN */
0x68c 0x0 /* CFG_MMC3_CMD_OUT */
0x690 0xab /* CFG_MMC3_DAT0_IN */
0x694 0x0 /* CFG_MMC3_DAT0_OEN */
0x698 0x0 /* CFG_MMC3_DAT0_OUT */
0x69c 0xdd /* CFG_MMC3_DAT1_IN */
0x6a0 0x0 /* CFG_MMC3_DAT1_OEN */
0x6a4 0x0 /* CFG_MMC3_DAT1_OUT */
0x6a8 0x0 /* CFG_MMC3_DAT2_IN */
0x6ac 0x0 /* CFG_MMC3_DAT2_OEN */
0x6b0 0x0 /* CFG_MMC3_DAT2_OUT */
0x6b4 0x1da /* CFG_MMC3_DAT3_IN */
0x6b8 0x0 /* CFG_MMC3_DAT3_OEN */
0x6bc 0x0 /* CFG_MMC3_DAT3_OUT */

mmc@480ad000 {

pinctrl-3 = <0x503>;
pinctrl-4 = <0x504 0xca>;
#address-cells = <1>;
#size-cells = <0>;
};
In the bootlog I can SDIO for mmc2 is initialized, but when I do a dev2mem on MMC3 IO delay registers I dont see any of this values changed.
Is there something else as well to be done ? The IO delay is set in pinctrl-4 (phandle 0xca)
Thanks,
Mike
