Subject: [PATCH v2 0/4] ARM: tegra: lg-x3: add missing nodes

With the recent kernel updates, Tegra30-based LG smartphones now support
several additional features, including an RGB-DSI bridge, DSI panels,
MUIC, a charger, a battery temperature sensor, OTG mode, and capacitive
buttons on the P895. Add required nodes to device trees.

Changes in v2:
- fixed dw9714 and tx13d100vm0eaa nodes
- added video device pipes graph

Regarding CHECK_DTBS output in v2:
- nvidia,tegra30-pcie, nvidia,tegra30-gmi, nvidia,tegra30-kbc,
  nvidia,tegra20-kbc, nvidia,tegra30-ahub are not documented yet
- nvidia,tegra30-vi was adjusted and applied, change did not apper yet
  (https://lore.kernel.org/lkml/176860988748.1688420.11717122647073678.b4-ty@nvidia.com/)
- st,m24c08 appers undocumented though it seems to be different from
  st,24c08, at least they google as separate devices. atmel,24c08 is not
  documented, though it is widey used in linux device trees and is
  supported by driver. Here is one of examples:
  https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/tree/arch/arm/boot/dts/allwinner/sun7i-a20-linutronix-testbox-v2.dts?h=next-20260123#n33
- onnn,mt9m114 does not have 'orientation' property, though it should
  include it since it is generic for camera devices
- ti,lp8720 and maxim,max77663 have txt documentation and are not yet
  converted to DT schema
- backlight in panel nodes was not added since lm3533 has no DT support
- missing '#io-channel-cells' in ti,tsc2007 addressed in
  https://lore.kernel.org/lkml/20260122193549.29858-2-clamor95@gmail.com/
- missing dsi controller properties of ssd2825 addressed in
  https://lore.kernel.org/lkml/20260123073411.7736-2-clamor95@gmail.com/
- missing '#io-channel-cells' in generic-adc-thermal was proposed in but rejected
