From bd54e739541ba59b7ff1e7ac778dba0b1b3d5461 Mon Sep 17 00:00:00 2001 From: David Bauer Date: Thu, 29 Apr 2021 14:07:40 +0200 Subject: [PATCH] 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.
