[PATCH v2 0/3] Add support for GPIO based CS

[Prajna Rajendra Kumar]

The Microchip PolarFire SoC SPI "hard" controller supports eight 
chip selects. However, only one chip select is physically wired. 
Therefore, use GPIO descriptors to configure additional chip select 
lines.

v1-> v2: 
 - Modified all commit messages for better understanding
 - driver - added spi_is_csgpiod() API to address review comment
 - bindings - fixed bindings to set the default value of num-cs

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