In order to use DMA When the DMA is available. This patch supports for r8a7790 SOC and developed base on the upstream-v3.17-rc7 and have tested on the Lager board. Please review it when you have time! Version 1: This is the patch of QSPI that support for r8a7790 SOC. The pupose of this patch is to transmit and receive the 32 bytes of data when the data already has prepared on Transmit/Receive Buffer. Using Transmit/Receive Buffer Data Trigger Number to do that instead transmits/receives a byte of data. With this patch will improve the speed of transfer data. This patch was developed base on the upstream-v3.17-rc5 and have tested on the Lager board.
