[PATCH v2 0/3] arm64: dts: ti: k3-am62p-verdin: Add device tree overlays

[Vitor Soares]

From: Vitor Soares <vitor.soares@xxxxxxxxxxx>

This series adds device tree overlays for the Toradex Verdin AM62P,
bringing it in line with the overlay support already present for the
Verdin AM62.

The first patch enables Bridge Tied Load (BTL) mode on the Nuvoton
NAU8822 audio codec present on the Verdin Development Board, combining
the two loudspeaker outputs for higher output power.

The second patch adds OV5640 CSI camera support on Verdin CSI_1 in two
variants: the current CSI Camera Set 5MP OV5640 with a 27 MHz oscillator
and the legacy CSI Camera Module 5MP OV5640 with a 24 MHz oscillator.

The third patch makes the MCU_UART0 (Verdin UART_4) reservation overlay
common to Verdin AM62 and Verdin AM62P. The shared overlay reserves the
UART for use by the MCU co-processor firmware as its debug UART.

Changes in v2:
 - Reworked the UART_4 MCU reservation overlay as a common AM62x Verdin
   overlay, moved it later in the series, and dropped Reviewed-by due to
   the patch rework.
 - Link to v1: https://lore.kernel.org/linux-devicetree/20260602141311.1366818-5-ivitro@xxxxxxxxx/
