Subject: [PATCH v11] arm64: dts: imx8qxp: Add jpeg encoder/decoder nodes
Date: Fri, 23 Apr 2021 13:14:14 +0300	[thread overview]
Message-ID: <20210423101414.20068-1-mirela.rabulea@oss.nxp.com> (raw)

From: Mirela Rabulea <mirela.rabulea@nxp.com>

Add dts for imaging subsytem, include jpeg nodes here.
Tested on imx8qxp only, should work on imx8qm, but it was not tested.

Changes in v11:
  Adress feedback from Aisheng Dong:
  - Rename img_jpeg_dec_clk/img_jpeg_enc_clk to jpeg_dec_lpcg/jpeg_enc_lpcg to make it visible it's lpcg not other type of clk
  - Drop the cameradev node, not needed for jpeg
  - Match assigned-clocks & assigned-clock-rates
