[PATCH 0/7] TQMLS102xA: New display overlays and small fixes

[Alexander Stein]

Hi,

this series adds several display overlays for HDMI, LVDS and RGB displays.
Additionally it fixes the license header and updates the sound card model
name similar to i.MX based platforms by TQ.

Best regards,
Alexander

[PATCH 1/7] ARM: dts: ls1021a-tqmals1021a: Fix license

[Alexander Stein]

With commit 784bdc6f2697c ("ARM: dts: ls1021a: change to use SPDX
identifiers") the SoC .dtsi specifies the license using SPDX tags.
Fix license according to the ls1021a.dtsi this platform DT files
are based on.

[PATCH 3/7] ARM: dts: ls1021a-tqmals1021a: Add HDMI overlay

[Alexander Stein]

This add an overlay for using the RGB-to-HDMI bridge.
Note: As DDC is directly connected to general I2C bus, there might be I2C
address conflicts. Hence not all displays might work.

Thanks for the comment. We are touching English grammar here and I might
be completely wrong.
IMHO this gerund is describing the power supply is missing the whole time.
In contrast to 'missed' which indicates it had been missed (just) once.
Anyway I don't have hard feelings.

Alexander

[PATCH 7/7] ARM: dts: ls1021a-tqmals1021a: change sound card model name

[Alexander Stein]

The card name for ALSA is generated from the model name string and
is limited to 16 characters. Use a shorter name to prevent cutting the
name.
MBLS1021A uses the same audio codec as most i.MX based starter kits
by TQ-Systems. Adjust the sound card model to i.MX based platforms,
as done by commit e6303798b6ac4 ("arm64: dts: imx8mp-tqma8mpql-mba8mpxl:
change sound card model name"). This allows sharing a default asound.conf
in BSP over all the kits.

I only followed the entries from get_maintainer.pl. Would you mind adding
arch/arm/boot/dts/nxp/ls to MAINTAINERS?
