Subject: [PATCH 0/2] mmc: rtsx: add support for async request

From: Micky Ching <micky_ching@...lsil.com.cn>

Add support for sd/mmc async request, which makes next request do dma_map_sg()
while previous request transfering data. This behaviour can improve card io
performance more than 10%.

Since rtsx mfd driver only provide a single function for transfering data,
so add three split functions for rtsx mmc driver.

  mfd: rtsx: add dma transfer function
  mmc: rtsx: add support for async request
