ASoC: Intel: bytcr_rt5640: Add DMI quirk for Vexia Edu Atla 10 tablet 5V
Browse files Browse the repository at this point in the history
The Vexia EDU ATLA 10 tablet comes in 2 different versions with
significantly different mainboards. The only outward difference is that
the charging barrel on one is marked 5V and the other is marked 9V.

The 5V version mostly works with the BYTCR defaults, except that it is
missing a CHAN package in its ACPI tables and the default of using
SSP0-AIF2 is wrong, instead SSP0-AIF1 must be used. That and its jack
detect signal is not inverted as it usually is.

Add a DMI quirk for the 5V version to fix sound not working.
