Subject: Input: appletouch - add Geyser IV support
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=009ad0e7b43d6cabd74e47db6180f14315b71417;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

Input: appletouch - add Geyser IV support

The new Core2 Duo MacBook Pro has a new keyboard+trackpad named
"Geyser IV".

According to the Info.plist in the OS X kext, it looks like the Geyser
IV trackpad is identical to the Geyser III trackpad: same IOClass
(AppleUSBGrIIITrackpad), same acceleration tables.
