Add the video clock controller for X1E80100, similar to sm8550.dtsi. It provides the needed clocks/power domains for the iris video codec. Reviewed-by: Bryan O'Donoghue <[email protected]> Signed-off-by: Stephan Gerhold <[email protected]> Reviewed-by: Konrad Dybcio <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Bjorn Andersson <[email protected]> Signed-off-by: Yijie Yang <[email protected]> Git-commit: a8a5ea012471dd19ea9cb4d668c27ac678e84a3e Git-repo: https://git.kernel.org/pub/scm/linux/kernel/git/qcom/linux.git
Add the IRIS video codec to accelerate video decoding/encoding. Copied mostly from sm8550.dtsi, only the opp-table is slightly different for X1E. For opp-240000000, we need to vote for a higher OPP on one of the power domains, because the voltage requirements for the PLL and the derived clocks differ (sm8550.dtsi has the same).

The reset and IOMMU management for remoteprocs like IRIS is implemented in the hypervisor for older targets such as X1E [1]. When running in EL2, this functionality is missing and the PAS interface normally used by IRIS to boot the video firmware is not working. The Venus driver supports starting the video firmware without using the PAS interface. The same code also works for X1E when running in EL2. However, for the new IRIS dt-bindings it was decided to avoid using the dummy "video-firmware" node in the device tree to describe the IOMMU [2]. Discussion is still ongoing how to describe this properly [3]. To avoid regressions when running in EL2, add a TODO in x1-el2.dtso for now and disable IRIS even when it was enabled by the board.

IRIS firmware for x1e80100-crd is already upstream in linux-firmware in the default path, so enable IRIS for the CRD to accelerate video decoding. It looks like the X1P CRD might need a different IRIS firmware (possibly even changes in the Linux kernel driver), so keep it local to the X1E CRD for now.

IRIS firmware for the Lenovo ThinkPad T14s is already upstream in linux-firmware at qcom/x1e80100/LENOVO/21N1/qcvss8380.mbn, so enable IRIS for the T14s with the corresponding firmware-name property.

Document the device tree binding for the HAMOA-IOT-EVK board, which uses the Qualcomm X1E80100 SoC. The EVK consists of a carrier board and a modular System-on-Module (SoM). The SoM integrates the SoC, PMICs, and essential GPIOs, while the EVK carrier board provides additional peripherals such as UART and USB interfaces.
