[PATCH 0/1] ARM: spi supports 32bytes buffer for DUAL and QUAD

[Cao Minh Hiep <cm-hiep@xxxxxxxxxxx>]

From: Hiep Cao Minh <cm-hiep@xxxxxxxxxxx>

Hi,

This patch will improve the DUAL and QUAD's performance of SPI,
that supported for GEN2 r8a7790 SOC in PIO mode. 
It sends/receives each 32bytes of data instead of each byte data 
as current situation.

This patch was developed based on the Mainline v4.9-rc3 and have 
tested on the Lager board.

Please consider the following patches for the r8a7790 Soc.

Thank you!
