Subject: [PATCH] spi: coldfire-qspi: Simplify the code to set register bits for transfer speed
Date: Thu, 20 Mar 2014 22:59:06 +0800 [thread overview]
Message-ID: <1395327546.25840.1.camel@phoenix> (raw)
spi core will use spi->max_speed_hz as transfer speed if the transfer speed was
not set. So we don't need to test t->speed_hz in mcfqspi_transfer_one().
