Subject: [PATCH 0/3] Add support for GPIO based CS
Date: Thu, 2 May 2024 15:34:07 +0100 [thread overview]
Message-ID: <20240502143410.12629-1-prajna.rajendrakumar@microchip.com> (raw)
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
