Thank you for pointing this out. I missed this difference.
I actually have a board with T113 SoC, and it looks like writing to
SPI_CCR@0x24 does nothing.
And it doesn't affect access to connected SPI NOR flash (read\write
operations are fine).
But I completely agree with you that this difference should be handled
by the spi driver.
