2021-02-03arm64: dts: meson: shorten audio card names for alsa compatibilityChristian Hewitt
This patch shortens all audio card model names by dropping the SoC prefix (for conformity) and rewording those that are still longer than alsa's 15 character name limit [0] to avoid userspace config issues.

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.
