From d570838efb6fb3154cbd08ab1b22d1f6442b1e78 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 8 Apr 2021 09:50:45 +0200 Subject: [PATCH] ARM/spi: spear: Drop PL022 num_chipselect A previous refactoring moved the chip select number handling to the SPI core and we missed a leftover platform data user in the ST spear platform. The spear is not using this chipselect or PL022 for anything and should be using device tree like the rest of the platform so just delete the offending platform data.
