There is a problem with the sd-uhs mode when doing a soft reboot. Switching back from 1.8v to 3.3v messes with the card, which no longer respond (timeout errors). According to the specification, we should perform a card reset (power cycling the card) but this is something we cannot control on this design. Then the only solution to restore the communication with the card is an "unplug-plug" which is not acceptable Until we find a solution, if any, disable the sd-uhs modes on this design. For the people using uhs at the moment, there will a performance drop as a result.

The LibreTech CC ("Le Potato") board provides four USB connectors. These are provided by a hub which is connected to the SoC's USB controller. Enable the SoC's USB controller to make the USB ports usable. Also turn on the HDMI_5V regulator when powering on the PHY because (even though it's not shown in the schematics) HDMI_5V also supplies the USB VBUS.

With the adequate configuration settings, u-boot will loop through the list of aliases looking for "ethernetX". By adding an ethernet alias, u-boot can fixup the local-mac-address property in the kernel's device tree using a value held in its environment variable ethaddr.

Changing the card voltage on the cc is not instantaneous, especially when switching from 3.3v to 1.8v. It take at least 30ms for the regulator to go from 3.3v to 1.8v. Add margin to that to make sure we don't upset the sdcard during the voltage switch Fixes: 61ff2af9b278 ("ARM64: dts: fixup libretech cc definition") Signed-off-by: NJerome Brunet <jbrunet@baylibre.com> Signed-off-by: NKevin Hilman <khilman@baylibre.com>

The libretech CC derives less from the p212 than initially thought. Several voltage regulators are different and the capabilities of the sdcard and emmc also differ. Deriving from the p212 is not convient anymore so the libretech is now derived from s905x definition directly.
