| Series | mmc: dw_mmc: Enable eMMC on E850-96 board | expand |
Hi Sam, Thanks for working on this, makes switching to upstream dts'es easier :) I tested the series on exynos4412-odroid-u2 and exynos5422-odroid-xu4. One issue for exynos4412-odroid to resolve below, with that fixed booting from both eMMC and sdcard works on my devices.

I've checked all other occurrences and this node (sdhci2 in exynos4412-odroid.dts) is the only place where I forgot to add 'bus-width'. Will fix it in v5 and send it out soon. [snip]

Some device tree properties for DW MMC block were updated in Linux kernel. Let's follow its example and rework corresponding properties in all Exynos device trees. Don't remove outdated properties yet, it'll be done later once DW MMC driver is updated accordingly to read the updated properties instead of outdated ones. Next properties are added: * samsung,dw-mshc-ciu-div and samsung,dw-mshc-sdr-timing: They were derived from outdated samsung,timing property. * fifo-depth (generic replacement for fifoth_val): FIFO depth was calculated from fifoth_val (using expressions from FIFOTH register description in TRM): fifo-depth = ((fifoth_val >> 16) + 1) * 2 * bus-width: generic replacement for samsung,bus-width * clock-frequency: generic replacement for bus_hz * non-removable: generic replacement for samsung,removable = <0> No functional change.
