I first tried to apply your series on top of next-20220630,
but was greeted by a bunch of different warnings on boot,
including endless RCU stall warnings.
However, even when booting next-20220630 without your patches,
I got the same warnings and RCU stall.

So I tested your series on top of v5.19-rc4 +
commit 0397d50f4cad ("spi: dt-bindings: Move 'rx-sample-delay-ns' to
spi-peripheral-props.yaml") cherry-picked,
(in order to avoid conflicts when applying your series,)
and the board was working as intended, no warnings or RCU stalls.

I tried both booting both via u-boot (with u-boots DTB)
and booting the kernel (with an initrd) directly.
I could successfully read data from the MMC in both cases.

Therefore:
