[PATCH v3 0/9] arm: am335x: Switch to upstream devicetree

[Markus Schneider-Pargmann (TI.com)]

The series is split into two logical groups:

- Patches 1-4: Fixes for am335x-evm to boot and support the LCD panel
  with the current u-boot devicetree.
- Patches 5-8: Make upstream devicetree working with uboot. This
  adds tick-timer, adds compatibility of the board code for different
  USB probing and updates the defconfig.

The series has been tested on am335x-evm. Note that I don't have all
other boards built with the am335x_*evm_*defconfig, so tests are
appreciated. buildman reports builds are working.

Changes in v3:
- Add patch to unify all config variants for the am335x-evm and similar
  boards. This also updates the upstream defconfig enablement patch to
  effectively switch all config variants to OF_UPSTREAM.
- Link to v2: https://lore.kernel.org/r/20251128-topic-am33-evm-oftree-v2026-01-v2-0-42a863304498@baylibre.com

Changes in v2:
- Most of the independent patches were extracted in smaller series
- Added patch to add vidconsole for am335x-evm
- Add chosen tick-timer to all devicetrees that are used with the
  am335x_evm_defconfig
- Link to v1: https://lore.kernel.org/r/20251118-topic-am33-evm-oftree-v2026-01-v1-0-91ce13c661e2@baylibre.com
