| H A D | sdhci-esdhc-imx.c | de3e1dd0 Fri Dec 21 03:20:53 CST 2018 BOUGH CHEN <haibo.chen@nxp.com> mmc: sdhci: usdhc: do not do tuning for DDR50 mode.
DDR50 tuning is optinally defined in sd 3.0 spec. And i.MX
uSDHC internally already uses a fixed optimized timing for
DDR50, normally does not require tuning for DDR50 mode.
This patch specify a new execute_tuning function for i.MX
uSDHC, do not impact i.MX eSDHC.
