Subject: [PATCH 09/16] mmc: host: omap_hsmmc: Prepare *set_timing() to be used for iodelay setting
Date: Fri, 16 Jun 2017 18:15:37 +0530	[thread overview]
Message-ID: <20170616124544.15046-10-kishon@ti.com> (raw)
In-Reply-To: <20170616124544.15046-1-kishon@ti.com>

No functional change. Add separate case statements for certain timing
like MMC_TIMING_SD_HS and MMC_TIMING_MMC_HS even though AC12_UHSMC_RES
has to be written to the AC12 register (same as for default modes).
Also have separate case sections for MMC_TIMING_UHS_SDR104 and
MMC_TIMING_UHS_HS200 even though the same UHSMC value has to be written
to the AC12 register. This is in preparation for setting iodelay
values.
