This was paused because the compatible for the Display SubSystem (DSS) had to be changed, along with the driver. The patch series adds DT nodes for Display SubSystem (DSS) and other peripherals required to enable the HDMI audio and video on the AM625 SK, AM62-LP SK, as well as the AM625 based Beagle-Play platforms. An HDMI monitor can be connected to the boards for the audio/video outputs. The series adding the compatible and basic driver support[0] is in the drm-misc-next and linux-next queues and is expected to be in the mainline by v6.6-rc1. Patches 5 and 7 have been picked up from TI's linux tree[1] based off linux-kernel v6.1. Change Log: V2 -> V3: - Updated the compatible from "ti,am65x-dss" to "ti,am625-dss". - Peripheral nodes like HDMI TX, HDMI connector are now added to k3-am62x-sk-common.dtsi instead of k3-am625-sk.dts, in order to support AM62-LP SK-EVM as well. - Dropped the HDMI master clock node as it is not connected on the EVM, and should not have been added in the first place. - Re-worded and Re-ordered commits. - Dropped Rahul Ravikumar's R-bs because of the changes. - Added AM625 based Beagle-Play for HDMI support. - Added HDMI audio support as well. V1 -> V2: - Removed repetitive data in dss_ports V2: https://lore.kernel.org/all/20220505134303.23208-1-a-bhatia1@ti.com/ V1: https://lore.kernel.org/all/20220427090850.32280-1-a-bhatia1@ti.com/ [0]: https://lore.kernel.org/all/20230616150900.6617-1-a-bhatia1@ti.com/ [1]: https://git.ti.com/cgit/ti-linux-kernel/ti-linux-kernel/log/?h=ti-linux-6.1.y-cicd Aradhya Bhatia (6): arm64: dts: ti: k3-am62x-sk-common: Update main-i2c1 frequency arm64: dts: ti: k3-am62-main: Add node for Display SubSystem arm64: dts: ti: k3-am62x-sk-common: Add DSS pinmux info arm64: dts: ti: k3-am62x-sk-common: Add support for HDMI output arm64: dts: ti: k3-am625-beagleplay: Add DSS pinmux info arm64: defconfig: Enable ITE_IT66121 HDMI transmitter Jai Luthra (1): arm64: dts: ti: am62x-sk: Add overlay for HDMI audio Nishanth Menon (1): arm64: dts: ti: k3-am625-beagleplay: Add HDMI support arch/arm64/boot/dts/ti/Makefile | 3 + arch/arm64/boot/dts/ti/k3-am62-main.dtsi | 23 +++ .../arm64/boot/dts/ti/k3-am625-beagleplay.dts | 182 ++++++++++++++++++ .../arm64/boot/dts/ti/k3-am62x-sk-common.dtsi | 119 +++++++++++- .../boot/dts/ti/k3-am62x-sk-hdmi-audio.dtso | 40 ++++ arch/arm64/configs/defconfig | 1 + 6 files changed, 367 insertions(+), 1 deletion(-) create mode 100644 arch/arm64/boot/dts/ti/k3-am62x-sk-hdmi-audio.dtso
