Subject: [PATCH v2] arm64: dts: ti: k3-am62-verdin: Fix SoM ADC compatible

From: João Paulo Gonçalves <joao.goncalves@...adex.com>

Fix Verdin AM62 on-SOM ADC compatible. Currently the hardware is not
correctly described in the DT, use the correct TI TLA2024 compatible that
matches what is assembled on the board.

The "ti,tla2024" compatible was introduced in Linux v5.19 and Verdin AM62
support was introduced in Linux v6.5.

The new DTB will not work on kernel older than v5.19, but this seems
unlikely to happen. U-Boot does not use the ADC node and a known Android 14
out-of-tree port uses a Linux Kernel 6.1.

With that said, despite this being a breaking change, it seems fair to
to not expect any regression because of it.
