Merge tag 'tegra-for-5.16-dt-bindings' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into arm/dt

dt-bindings: Changes for v5.16-rc1

This contains the DT bindings for the NVDEC hardware video decoder found
on Tegra210 and later chips as well as a node name fix for the examples
in the Tegra194 PCIe controller (endpoint mode) DT bindings.

title: Device tree binding for NVIDIA Tegra NVDEC

description: |
  NVDEC is the hardware video decoder present on NVIDIA Tegra210
  and newer chips. It is located on the Host1x bus and typically
  programmed through Host1x channels.
