[ Upstream commit 6917192378c1ce17ba31df51c4e0d8b1c97a453b ]
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.
