Subject: [PATCH 07/14] mmc: jz4740: Set clock rate to mmc->f_max rather than JZ_MMC_CLK_RATE
Date: Fri,  9 Mar 2018 12:12:12 -0300	[thread overview]
Message-ID: <20180309151219.18723-8-ezequiel@vanguardiasur.com.ar> (raw)
In-Reply-To: <20180309151219.18723-1-ezequiel@vanguardiasur.com.ar>

From: Alex Smith <alex.smith@imgtec.com>

The maximum clock rate can be overridden by DT. The clock rate should
be set to the DT-specified value rather than the constant JZ_MMC_CLK_RATE
when this is done. If the maximum clock rate is not set by DT then
mmc->f_max will be set to JZ_MMC_CLK_RATE.
