From a52db659c79ceede44e2d5ca63ca058d49df8dea Mon Sep 17 00:00:00 2001 From: Christophe Ricard Date: Sun, 20 Mar 2016 19:30:17 +0100 Subject: [PATCH] spi: pxa2xx: Fix cs_change management Fix cs_change management so that it is in line with other spi drivers. In the spi core api helpers such as spi_bus_lock/unlock and spi_sync_locked or cs_change field in spi_transfer help to manage chip select from the device driver. The driver was setting the chip select to idle if the message queue was empty despite cs_change or other status field set by spi_bus_lock/unlock or spi_sync_locked.
