2014-02-07MMC: DWMMC: Correct the CLKDIV register valueRajeshwari S Shinde
This patch corrects the divider value written to CLKDIV register. Since SDCLKIN is divided inside controller by the DIVRATIO value set in the CLKSEL register, we need to use the same output clock value to calculate the CLKDIV value. as per user manual: cclk_in = SDCLKIN / (DIVRATIO + 1) Input parameter to mmc_clk is changed to dwmci_host, since we need the same to read DWMCI_CLKSEL register. This improves the read timing values for channel 0 on SMDK5250 from 0.288sec to 0.144sec Signed-off-by: Rajeshwari S Shinde <rajeshwari.s@samsung.com> Acked-by: Jaehoon Chung <jh80.chung@samsung.com> Signed-off-by: Pantelis Antoniou <panto@antoniou-consulting.com>

2013-10-31mmc: dw_mmc: change the callback function name.Jaehoon Chung
To prevent the confusion, use the get_mmc_clk() instead of mmc_clk(). get_mmc_clk() is more exactly name. Signed-off-by: Jaehoon Chung <jh80.chung@samsung.com> Acked-by: Pantelis Antoniou <panto@antoniou-consulting.com>
