arm64: dts: rockchip: set num-cs property for spi on px30
From: Heiko Stuebner <heiko.stuebner@...> Date: Fri, 19 Jan 2024 11:10:09 +0100
Commit-Message
The px30 has two spi controllers with two chip-selects each. The num-cs property is specified as the total number of chip selects a controllers has and is used since 2020 to find uses of chipselects outside that range in the Rockchip spi driver. Without the property set, the default is 1, so spi devices using the second chipselect will not be created. Fixes: eb1262e3cc8b ("spi: spi-rockchip: use num-cs property and ctlr->enable_gpiods") Signed-off-by: Heiko Stuebner <heiko.stuebner@...>
