Hi Akash,

Thanks for testing! It looks like sdhci driver decides to clock your
eMMC at 52MHz which works, while for my eMMC it choses 26MHz.
Unfortunately, clk_rk3568 driver supports only certain clock rates,
and fails with e.g. 25MHz, 26MHz. SDHCI driver doesn't check for
errors and fails silently, I'll send a fix later today.

Yeah, you can see that regulator status is incorrect. Currently,
rk_i2c driver is non-functional on rk3568 in u-boot master. It's
caused by missing pinctrl driver (it's already merged into rockchip
custodian tree)

Vasily
