Subject: [PATCH 0/2] spi: Fix problem with interrupted slave transmission
Date: Tue, 24 Sep 2019 13:05:45 +0200 [thread overview]
Message-ID: <20190924110547.14770-1-lukma@denx.de> (raw)
This patch series fixes problem with recovering Vybrid's NXP DSPI
controller state after master transmission distortion.
It was tested with a setup where /dev/spidevX.Y devices were used in
a loopback mode (provided by proper HW connections). During this test
the distortion was introduced and the system was assessed if it is
possible to continue correct SPI transmission.
This series applies clearly on v5.2 (tag) and current mainline:
