| H A D | ti_sdhci.c | diff 259356 Fri Dec 13 20:52:19 MST 2013 ian MFC r257518, r257519: TI sdhci driver improvements, mostly related to fdt data... Use the published compatible strings (our own invention, "ti,mmchs" is still accepted as well, for now). Don't blindly turn on 8-bit bus mode, because even though the controller supports it, the board has to be wired appropriately as well. Use the published property (bus-width=<n>) and honor all the valid values (1,4,8). The eMMC device on a Beaglebone Black is wired for 8-bit, update the dts. The mmchs controller can inherently do both 1.8v and 3.0v on the first device and 1.8v only on other devices, unless an external transceiver is used. Set the voltage automatically for the first device and honor the published fdt property (ti,dualvolt) for other devices. 259356 Fri Dec 13 20:52:19 MST 2013 ian MFC r257518, r257519: TI sdhci driver improvements, mostly related to fdt data...
