arm64: dts: amlogic: set HDMI vendor info on vendor-branded boards

[allolive]

The shared coreelec_g12b_common.dtsi sets the amhdmitx vend_data product_desc to "G12B" with the comment "Should modified by Customer". That generic SoC-family string is what AVRs and TVs display in their HDMI source / input list when they read the HDMI Vendor-Specific InfoFrame from the box.

Override the board's vend_data so the broadcast identifier matches the actual product instead of the generic SoC name.

Before:
$ cat /sys/firmware/devicetree/base/amhdmitx/vend_data/vendor_name
Amlogic
$ cat /sys/firmware/devicetree/base/amhdmitx/vend_data/product_desc
G12B # AVR shows "G12B"

After:
vendor_name = UGOOS
product_desc = AM6B+ # AVR shows "AM6B+"

This for all "G12B" variants hopefully.

Can you please rebase the PR?

Also you might do the same for all other unique DTBs?

[allolive]

@Portisch, I rebased and extended this to every vendor-branded boards in with similar issues.

I used the existing model = "..." field on each board as the source for vendor_name / product_desc (first word → vendor, rest → product), with a couple of manual touches.

Only tested on my AM6B+ (UGOOS/AM6B+ confirmed at runtime), so fingers crossed nothing got mis-named or broke for boards I don't have...

[Portisch]

Please also squash arm64: dts: ugoos-am6b-plus: set HDMI vendor info into arm64: dts: amlogic: set HDMI vendor info on vendor-branded boards to have only one commit.

Please remove arch/arm64/boot/dts/amlogic/g12b_a311d_bananapi_m2s.dts as it's set already by g12b_s922x_bananapi_m2s.dts.

[allolive]

Good catch. Done.

I just did hit this issue:

vendor: String representing the manufacturer (e.g., "AMD", "Intel", "NVIDIA"). Maximum 8 characters.
product: String describing the source device (e.g., "Radeon", "Core i7"). Maximum 16 characters.

@Portisch may I ask how did you test that?

As for the updated vendor names, I propose the following changes:

• Libre-Computer (14) -->> Libre (5)
• Hardkernel (10) -->> Hardkrn (7)
• Sinovoip (8) -->> Sinovip (7)
• Homatics (8) -->> Homatic (7)
• MagicSee (8) -->> Magic (5)

If you're good with that, I'll push an update.

[Portisch]

This was a good job for AI, to filter it he changes and check the strings.

Please update this PR now after merge of #16.

I will check the to long strings later on.
