Subject: [PATCH v6 0/7] drm/bridge: imx: Add HDMI PAI driver on i.MX8MP
Date: Thu, 4 Sep 2025 15:05:53 +0800 [thread overview]
Message-ID: <20250904070600.1361165-1-shengjiu.wang@nxp.com> (raw)
The HDMI TX Parallel Audio Interface (HTX_PAI) is a digital module that
acts as the bridge between the Audio Subsystem to the HDMI TX Controller.
Add HDMI PAI driver on i.MX8MP to make HDMI audio function fully work.
changes in v6:
- remove mutex in dw_hdmi_set_sample_iec958()
changes in v5:
- add empty line commit message for patch 7
- remove blank line in dts node
- add component_unbind_all when dw_hdmi_probe return error
changes in v4:
- separate dts for soc and board
- bind hdmi_pai with hdmi_tx by moving some code to .bind() and .unbind()
- add "select DRM_DW_HDMI" to fix build error reported by test robot
- remove unnecessary code/definition in pai driver
changes in v3:
- add space and 'U' in asoundef.h
- add more commit message for binding doc commit
- add bitfield.h header for fixing build error
changes in v2:
- address some comments on commit messages
- add two more commits:
add definitions for the bits in IEC958 subframe
add API dw_hdmi_set_sample_iec958() for iec958 format
- use component helper in hdmi_pai and hdmi_tx driver
- use regmap in hdmi_pai driver.
- add clocks in binding doc
