Summary: OMAP patch causes SPI bus transaction failure on TI CPU Commit: c859e0d479b3b4f6132fc12637c51e01492f31f6 Kernel version: 5.10.87
The detailed description:
I know this is a old commit at this point, but we have observed a regression caused by this commit. It causes improper toggle during a SPI transaction with a microcontroller. The CPU in use is Texas Instruments AM3352BZCZA80. The microcontroller in use is a PIC based micro. I have logic capture images available to show the signal difference that is causing confusion on the SPI bus.
