From 55e2fff639d4297ffeb478113aef6d3e26c2c4c2 Mon Sep 17 00:00:00 2001 From: David Bauer Date: Wed, 17 Feb 2021 02:44:55 +0100 Subject: [PATCH 1/2] spi: ath79: add SPI_MASTER_GPIO_SS flag Add the SPI_MASTER_GPIO_SS flag for the spi-ath79 driver. Otherwise, the custom chipselect function is never called. This breaks hardware, where the three dedicated chipselect lines are used instead of generic GPIO pins.
