Subject: [PATCH] spi: atmel: Fix DMA-setup for transfers with more than 8 bits per word.
Date: Mon, 19 Oct 2015 14:54:44 -0600 [thread overview]
Message-ID: <1445288084-31805-1-git-send-email-davidm@egauge.net> (raw)
The DMA-slave configuration depends on the whether <= 8 or > 8 bits
are transferred per word, so we need to call
atmel_spi_dma_slave_config() with the correct value.
