[PATCH linux-next v2 0/1] improve imx spi performance

2017-05-01 Thread jiada_wang
From: Jiada Wang previously burst length (BURST_LENGTH) is always set to equal to bits_per_word, causes a 10us gap between each word in transfer, which significantly affects performance. This patch set uses 32 bits tranfser to simulate lowers bits transfer, and by set burst length to maximum pos
