From e2e9f6d9f9bd7449ff113c157b639ce1a24b9d3f Mon Sep 17 00:00:00 2001 From: David Bauer Date: Sat, 24 Apr 2021 16:14:48 +0200 Subject: [PATCH 2/2] spi: ath79: set number of chipselect lines All chipsets from AR7100 up to QCA9563 have three dedicated chipselect lines for the integrated SPI controller. Remove the number of chipselects from the platform data, as there is no need to manually set this to a different value.
