[PATCH 0/2] arm64: dts: qcom: x1e80100-vivobook-s15: Add usb a and sd-card reader

[Maud Spierings via B4 Relay]

The Asus Vivobook s15 has 2 5gbps usb A ports on the right side which
are controlled by the usb_mp controller enable them and the retimers
required.

There is also a micro sd-card reader on the left side below the two
usb-c ports, this one is attached to the usb_2 controller. Enable it and
the retimer to enable the micro sd-card reader.

The micro sd-card reader seems to have so interesting behaviour, on my
machine and someone elses it kind of half works, but not really, the
same under windows, unusable. Either we both got unlucky with a hardware
defect or there is something else going on, however two other people did
succesfully test it, one of which on (free?)bsd instead of linux even.
One hypothesis is that this area is where the charging circuitry is,
which gets *very* hot while charging and might damage this bit of
hardware. However this is very much speculation and not based on
anything concrete.

Symptoms of dysfunctional sd-card reader:
The sd card will get detected, a usb device will appear as "Genesys Logic
STORAGE DEVICE" 05e3:0747

OpenBSD ;).  And yes, the SD-card reader works just fine for me with
this series.
