Description

• Enable SPI in the KIT_PSC3M5_EVK board configuration.
• Configure SCB2 for SPI on P7.0–P7.2 and map P7.3 as the chip-select GPIO.
• Expose the SPI pins through the variant’s Arduino pin aliases.
• Give SPI its own peripheral clock divider to keep its runtime divider changes separate from CAN.

One thing to note: Right now there is problem in the SPI.endTransaction() function, which is not properly releasing the allocated resources of the SPI bus. I have already fixed the corresponding function (ifx_cat1_spi_release() ) in the spi_infineon_pdl_.c file, which did the trick.

Since this is only a local fix, we need to find a solution how to either raise a ticket to get it fixed or fix it ourself and create a PR in the upstream.
