Subject: [PATCH v3 7/8] arm64: dts: freescale: Add the BOE av101hdt-a10
variant of the Moduline Display
From: Maud Spierings <maudspierings@...ontroll.com>
Add the BOE av101hdt-a10 variant of the Moduline Display, this variant
comes with a 10.1 1280x720 display with a touchscreen (not working in
mainline).
Signed-off-by: Maud Spierings <maudspierings@...ontroll.com>

Currently the backlight driver is not available, this will be upstreamed
in a future patch series. It is a Maxim max25014atg.
The touchscreen has a Cypress CYAT81658-64AS48 controller which as far as
I know is not supported upstream, the driver we currently use for this is
a mess and I doubt we will be able to get it in an upstreamable state.
