[PATCH v2 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.

Changes in v2:
* Collected Frank's R-b
* Improved commit message on patch 4
* CC'ed imx@lists.linux.dev as well

Best regards,
Alexander

[PATCH v2 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.

[PATCH v2 4/7] ARM: dts: ls1021a-tqmals1021a: Add LVDS overlay for Tianma TM070JVGH33

[Alexander Stein]

This adds an overlay for the supported LVDS display tianma tm070jvhg33.
The on-board RGB-to-LVDS encoder and DCU graphics chain are configured
accordingly. Add power supply as well, which had been missing all the time.

[PATCH v2 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.
