-From: Masaharu Hayakawa <masaharu.hayakawa.ry@renesas.com>
-Date: Wed, 1 Feb 2017 10:59:39 +0900
-Subject: [PATCH] mmc: sh_mobile_sdhi: Add R-CarGen3 SDHI-SEQUENCER support
-
-This is Workaround patch for SDHI-DMAC restriction of R-Car H3(WS1.1)/M3(WS1.0).
-Restriction: Mismatch of the transfer completion interrupt time and data transfer
-completion time.
-Overview: It does not take into account the bus response, the transfer completion
-interrupt IP outputs is in the early out.Therefore, when carrying out the data
-verification data read from the SD card, there is a possibility that the data of
-the last sector might be missing.(MMC Interface is also the same.)
-
-S/W Workaround: The last sector data is preserved by reading data for 2 sectors
-extra in the SDHI Driver of Linux kernel.
-
-The SDHI Driver achieves a dummy read for 2 sectors by the SDHI-SEQ function.
-In case of eMMC: CMD17(MMC_READ_SINGLE_BLOCK) and CMD18(MMC_READ_MULTIPLE_BLOCK)
- were requested, CMD8(SEND_EXT_CSD) is carried out additionally twice.
-In case of SD card: CMD17(MMC_READ_SINGLE_BLOCK) and CMD18(MMC_READ_MULTIPLE_BLOCK)
- were requested, 1024 bytes are read additionally by CMD18.
-In other cases: CMD17 and CMD53(SD_IO_RW_EXTENDED) is carried out additionally twice.

-Subject: [PATCH] ASoC: ak4613: Improve counting DAI number
-
-Add the startup function to count DAI instead of hw_params.
-This change matches the number of opened DAIs.
-If this change isn't applied, you may get unexpected error due to
-mismatching of count. Since the excution number of hw_params and
-shutdown may be different, the mismatching happens.
