You miss a commit message which is _very_ important given the type of

Change IDs have nothing to do here.
However a Fixes and a Signed-off-by are welcome.
You'll also need to Cc: Rob H. in your v2.

I forgot to mention, while you're at it, after fixing the bindings,
could you please convert it to yaml?

If you want to re-implement the mmc clock part directly in the nand
driver, you should provide both clock inputs, like the mmc driver (in
addition to the pclk) ... Even if you plan on using only FDIV2 in the
driver, this what the HW is.
Something like:
clock-names = "core", "clkin0", "clkin1";
clocks = <&clkc CLKID_SD_EMMC_C>,
<&clkc CLKID_SD_EMMC_C_CLK0>,
<&clkc CLKID_FCLK_DIV2>;
>> + sd_emmc_c_clkc = <0xffe07000>;
This is not how you provide memory regions

sd_emmc_c_clkc should be documented, but it should be either:
- a syscon
- in reg
but since 0xffe07000 is part of the emmc memory space, you can't simply
put this address like that and pass it to a random undocumented property.
Adding "syscon" to the sd_emmc_c compatibles, and passing the sd_emmc_c node as syscon
could actually work.

sd_emmc_c_clkc should be documented, but it should be either:
- a syscon
- in reg
but since 0xffe07000 is part of the emmc memory space, you can't simply
put this address like that and pass it to a random undocumented property.
Adding "syscon" to the sd_emmc_c compatibles, and passing the sd_emmc_c node as syscon
could actually work.
