Subject: [PATCH 0/2] spi: atmel-quadspi: fix resume call
Date: Fri, 28 Jun 2019 15:30:30 +0000 [thread overview]
Message-ID: <20190628153009.7571-1-tudor.ambarus@microchip.com> (raw)
From: Tudor Ambarus <tudor.ambarus@microchip.com>
When waking up from the Suspend-to-RAM state, the following error
was seen:
m25p80 spi2.0: flash operation timed out
The flash remained in an undefined state, returning 0xFFs.
Fix it by setting the Serial Clock Baud Rate, as it was set
before the conversion to SPIMEM.
Tested with sama5d2_xplained and mx25l25673g spi-nor in
Backup + Self-Refresh and Suspend modes.

spi: atmel-quadspi: void return type for atmel_qspi_init()
