From 9ff254f14b1994ec9a2866b0c4abbb2bb202e0aa Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Fri, 19 Jan 2024 11:16:56 +0100 Subject: [PATCH] arm64: dts: rockchip: set num-cs property for spi on px30 [ Upstream commit 334bf0710c98d391f4067b72f535d6c4c84dfb6f ] 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.
