2019-10-07arm64: dts: meson: libretech-cc: update model and compatibleChristian Hewitt
Shorten the model description to improve readability in some app GUIs that show the string. Update compatible to be more descriptive, using the format of the LaFrite board in meson-gxl-s805x-libretech-ac.dts.

According the datasheets, emmc v2 chips (gxbb and gxl) don't support more that 100Mhz in UHS-1 SD modes and HS in SDIO. Align the max-frequency to 100MHz for UHS-1 and 50MHz for HS Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>

While some 3.3v eMMC 4.0 are available from libretech, Only the 1.8v 5.0 modules are recommended and supported for the aml-s905x-cc. the 1.8v is provided by LDOs on the eMMC card, from vcc 3.3v Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Acked-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by: Kevin Hilman <khilman@baylibre.com>
2019-05-21arm64: dts: meson: libretech-cc: set eMMC as removableJerome Brunet
The eMMC on this board is add-on module which is not mandatory. Removing 'non-removable' property should prevent some errors when booting a board w/o an eMMC module present.

2019-01-14arm64: dts: meson: Fix mmc cd-gpios polarityLoys Ollivier
Commit 89a5e15bcba8 ("gpio/mmc/of: Respect polarity in the device tree") changed the behavior of "cd-inverted" to follow the device tree bindings specification: According to SDHCI standard, CD lines are specified as "active low". Using the "cd-inverted" property means that the CD line is "active high". Fix the SD card description for meson by setting the cd-gpios as "active low", according to the boards specifications, and dropping the "cd-inverted" property.

2018-06-27ARM64: dts: meson: disable sd-uhs modes on the libretech-ccJerome Brunet
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".

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.
