From 342e3ce0f6f4691b31b1c7c9c3ae37160c4a82d2 Mon Sep 17 00:00:00 2001 From: Andy Shevchenko Date: Tue, 23 Nov 2021 21:27:21 +0200 Subject: [PATCH] ARM: pxa/lubbock: Replace custom ->cs_control() by GPIO lookup table SPI PXA2xx driver supports GPIO chipselect by querying for known GPIO connection ID. Replace custom ->cs_control() by GPIO table, so the driver will use generic approach on this platform.
