From: Vitor Soares <vitor.soares at toradex.com>

Hardware chip select does not work correctly on main_spi0 and main_spi2
controllers on the Aquila AM69 module. Testing revealed main_spi2 loses
CS state during runtime PM suspend, while main_spi0 cannot drive CS HIGH
when bus is idle. This series switches both controllers to use GPIO-based
chip select instead.

Vitor Soares (2):
  arm64: dts: ti: k3-am69-aquila: change main_spi0/2 CS to GPIO mode
  arm64: dts: ti: k3-am69-aquila-clover: change main_spi2 CS0 to GPIO
    mode
