Hello,
TI added support to the spi-omap2-mcspi.c driver here in 2019: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/commit/?id=90201382e1c3a822c7b44d0c1936df8f407580e7
The latest SDK https://www.ti.com/tool/PROCESSOR-SDK-AM437X includes this as part of the tree.
The documentation indicates SPI Slave is not supported: https://software-dl.ti.com/processor-sdk-linux/esd/AM437X/07_03_00_005/exports/docs/linux/Foundational_Components/Kernel/Kernel_Drivers/SPI.html
It appears there is a discrepancy between the documentation and the code/sdk. Can this discrepancy be explained?
Thanks,
Mike
