6 This file documents differences between the core properties in mmc.txt
7 and the properties used by the sdhci-sprd driver.
10 - compatible: Should contain "sprd,sdhci-r11".
11 - reg: physical base address of the controller and length.
12 - interrupts: Interrupts used by the SDHCI controller.
13 - clocks: Should contain phandle for the clock feeding the SDHCI controller
14 - clock-names: Should contain the following:
15 "sdio" - SDIO source clock (required)

| D | mmc-async-req.rst | 2 MMC Asynchronous Request
11 pre-fetch makes the cache overhead relatively significant. If the DMA
13 transfer, the DMA preparation overhead would not affect the MMC performance.
15 The intention of non-blocking (asynchronous) MMC requests is to minimize the
16 time between when an MMC request ends and another MMC request begins.
18 Using mmc_wait_for_req(), the MMC controller is idle while dma_map_sg and
19 dma_unmap_sg are processing. Using non-blocking MMC requests makes it
21 MMC request.
23 MMC block driver
26 The mmc_blk_issue_rw_rq() in the MMC block driver is made non-blocking.
