Subject: [PATCH 0/2] spi: imx: don't loop endlessly
Date: Wed,  2 Aug 2017 21:39:05 +0200	[thread overview]
Message-ID: <20170802193907.4317-1-u.kleine-koenig@pengutronix.de> (raw)

Hello,

during bringup of an i.MX7 board I am faced with cspi_2_3_xchg_single not
returning. I don't know yet why this happens, but with this patch set it at least
doesn't block barebox.

I didn't test on a working board, maybe the timeout (10 µs) I chose is too tight?

Best regards
Uwe
