Subject: [PATCH v1 1/1] spi: pxa2xx: Clear all RFT bits in reset_sccr1() on Intel Quark
Date: Wed,  6 Jul 2016 12:08:11 +0300	[thread overview]
Message-ID: <1467796091-142927-1-git-send-email-andriy.shevchenko@linux.intel.com> (raw)

It seems the commit e5262d0568dc ("spi: spi-pxa2xx: SPI support for Intel Quark
X1000") misses one place to be adapted for Intel Quark, i.e. in reset_sccr1().

Clear all RFT bits when call reset_sccr1() on Intel Quark.

Fixes: e5262d0568dc ("spi: spi-pxa2xx: SPI support for Intel Quark X1000")
