[PATCH 0/3] Add support for GPIO based CS

Posted by Prajna Rajendra Kumar 1 year, 7 months ago

The Microchip PolarFire SoC SPI controller supports multiple 
chip selects. However, only one chip select is connected in the MSS. 
Therefore, use GPIO descriptors to configure additional chip select 
lines.

Prajna Rajendra Kumar (3):
  spi: spi-microchip-core: Add support for GPIO based CS
  spi: dt-bindings: Add num-cs property for mpfs-spi
  spi: spi-microchip-core: Fix the number of chip selects supported
