Subject: [PATCH v2 0/2] spi: bcm-qspi: Fix spi-nor chip select logic for BSPI
Date: Thu, 26 Apr 2018 14:47:59 -0400 [thread overview]
Message-ID: <1524768481-16347-1-git-send-email-kdasu.kdev@gmail.com> (raw)
When using the spi-nor master controller always verify the chip select
bit in the cs register. Also do not use CDRAM PCS bit in BSPI mode.
Additionally make sure to enable/disable BSPI_MAST_N_BOOT_CTRL while using
BSPI mode.
V2 changes:
- Added "Fixes:" tag to 1/2 and 2/2 patches

spi: bcm-qspi: Avoid setting MSPI_CDRAM_PCS for spi-nor master
spi: bcm-qspi: Always read and set BSPI_MAST_N_BOOT_CTRL
