| Series | [v6] arm64: dts: qcom: Add support for Xiaomi Poco F1 (Beryllium) | expand |
Hi Konrad, I couldn't find answer to your question around missing (regulatorname)-supply properties. Need help in figuring out that part.

When the phone boots up and RPM(H) kicks in, you should see regulators probing like "s1 supplied by foo". Without the *-supply stuff, you will likely get "supplied by regulator-dummy". This happens here [1] and to my knowledge it is the "eletrical wiring" for Linux, as in it makes Linux aware of which regulators are connected electrically to the same supply (so that kernel knows when the supply is on and what voltage it's at). For qcom platforms, this is common per-pmic (afaik, please check if you are able to!), so you can likely just copy-paste that part from msm8998-mtp.dtsi, which also uses pm(i)8998. Konrad

Thank you for the pointer. I dug around the vph_pwr fixed-regulator node used by fellow sdm845 devices. I assume it is safe to copy it from sdm845-mtp but I couldn't verify it in the downstream device-tree, so I'm a bit hesitant. My main concern is that I don't want to burn down my only device :) I did find a few regulator nodes downstream which matches with upstream sdm845-mtp but since I'm not using any of them in my beryllium dts, I'm going to skip them for now. As you pointed out, in case of regulator lookup failure Linux will fall back to dummy regulators, which is working fine for me so far. Also I see that vdd-*-supply properties are optional according to Documentation/devicetree/bindings/regulator/qcom,rpmh-regulator.txt, so I assume it is safe to skip them?

Looking at their DTSes, Xiaomi doesn't seem to stray far away from MTP designs. > As you pointed out, in case of regulator lookup failure Linux will > fall back to dummy regulators, which is working fine for me so far. > Also I see that vdd-*-supply properties are optional according to > Documentation/devicetree/bindings/regulator/qcom,rpmh-regulator.txt, > so I assume it is safe to skip them? Yes, but keep in mind it would be a good idea to add them later, after you're sure everything's okay :) P.S. My current daily driver is Xiaomi Mi 8, which is basically Poco with an OLED and glass back (among some other minor nicer things), so thanks for your work, I might benefit from it in the future :) Konrad

Add initial dts support for Xiaomi Poco F1 (Beryllium). This initial support is based on upstream Dragonboard 845c (sdm845) device. With this dts, Beryllium boots AOSP up to ADB shell over USB-C. Supported functionality includes UFS, USB-C (peripheral), microSD card and Vol+/Vol-/power keys. Bluetooth should work too but couldn't be verified from adb command line, it is verified when enabled from UI with few WIP display patches. Just like initial db845c support, initializing the SMMU is clearing the mapping used for the splash screen framebuffer, which causes the device to hang during boot and recovery needs a hard power reset. This can be worked around using: fastboot oem select-display-panel none To switch ON the display back run: fastboot oem select-display-panel But this only works on Beryllium devices running bootloader version BOOT.XF.2.0-00369-SDM845LZB-1 that shipped with Android-9 based release. Newer bootloader version do not support switching OFF the display panel at all. Signed-off-by: Amit Pundir <amit.pundir@linaro.org> --- My WIP tree with a few out-of-tree patches to support display, touchscreen, wifi, audio etc is here: https://github.com/pundiramit/linux/commits/beryllium-mainline v6: Renamed dts file to include vendor (xiaomi) name. Moved reserved memory changes in the main node. Renamed model to phone's pretty name. Removed the mmc drive strength comment to avoid further confusion. Sorted the entries in alphabetical order, but additional pinctrl entries are still defined at the end to align with the upstream db845c dts. v5: Bumped &tz_mem size from 0x2d00000 to 0x4900000 (to include downstream &removed_region), all the way up to &qseecom_mem. v4: Added more downstream reserved memory regions. It probably need more work, but for now I see adsp/cdsp/wlan remoteprocs powering up properly. Removed the regulator nodes not required for the device, as suggested by Bjorn. Also added couple of clocks to protected clocks, which is needed for display to work. v3: Added a reserved-memory region from downstream kernel to fix a boot regression with recent dma-pool changes in v5.8-rc6. v2: Updated machine compatible string for seemingly inevitable future quirks. arch/arm64/boot/dts/qcom/Makefile | 1 + .../boot/dts/qcom/sdm845-xiaomi-beryllium.dts | 383 +++++++++++++++++++++ 2 files changed, 384 insertions(+) create mode 100644 arch/arm64/boot/dts/qcom/sdm845-xiaomi-beryllium.dts
