Subject: [PATCH] quirks: Add Apple MTP touchpad quirk
|
|
|
|
Apple M2 (and presumably newer) laptops now embed the touchpad
|
|
controller into the main SoC, and use a new internal communications
|
|
protocol between it and the main CPU. This isn't really a "bus" like
|
|
SPI or I2C, so the downstream kernel driver currently uses the (not
|
|
well supported) HOST bus type. MatchBus can't match on that, so let's
|
|
just use a name match (plus the vendor ID, which is still valid and
|
|
the usual Apple one).
