arm64: add support for MSM8920, add support for motorola-perry by agrecascino · Pull Request #48 · msm89x7-mainline/linux

agrecascino · 2026-04-18T09:36:08Z

It's here. The future of computing. A low end phone from 2016.

Implement reset GPIO handling logic for the rmi_i2c driver. This logic is required for some mobile devices to successfully initialize the touch controller. As there are no datasheets available, the timings were taken from the GPLv2+ licensed synaptics-dsx-v2.1 vendor driver release. Tested-On: Motorola G5 Plus (Potter / XT1685) Signed-off-by: Felix Kaechele <felix@kaechele.ca>

Add add proper descriptions and your SoB for your commits

MSM8920 is essentially MSM8917 with MSM8953's modem stack. It has bigger modem firmwares that require larger memory regions, IPA, and therefore a slightly different clock situation. We hook up the clocks for IPA, and add the corresponding nodes to a new dtsi. Signed-off-by: Catherine Frederick (coolguy) <serenity@floorchan.org>

Please separate rpmcc changes and send it to upstream. Also send an initial 8920 support with perry to upstream.
I will wait with merge until that.

Do this device have only 1 panel variant?

Old PR but I want to note that my Moto E4 (perry) has an Ofilm panel.

Can you link relevant part from msm8952.c?

Adoption note (DCO / CONTRIBUTING): we’re picking up this stalled series from Project Xylitol (postmarketOS on XT1765 / perry). Original authors remain credited via existing Signed-off-by lines; new re-rolls will add our SoB.

Hardware evidence since this draft:

perry boots mainline-ish msm89x7 on real XT1765 with the local carry of these patches
This unit has an Ofilm panel (not only Tianma); panel side is tracked as linux-panel-drivers#8 (multi-panel config; extends new device: Huawei MediaPad T3 10 (huawei-agassi) #6)

Planned re-roll order (matches barni2000’s gate + CONTRIBUTING upstream-first for shared files):

Split rpmcc-msm8920 (+ bindings) as its own upstream-aimed series
Minimal msm8920.dtsi (drop no-op overrides vs current msm8917.dtsi; address MSS/IPA evidence question)
Refresh perry DTS (review fixes: pinctrl on panel node, licenses, non-exec bits, multi-panel note) as a new PR if this draft stays unmoved
Keep panels in linux-panel-drivers (not this tree)

Won’t force-push this branch; expect a replacement series. Tracking: https://github.com/aneesh-pradhan/xylitol/issues/13

aneesh-pradhan · 2026-07-22T21:33:27Z

Picking this up as discussed — re-rolled against current msm89x7/7.1.3 addressing @barni2000's review comments (rpmcc split, memory overrides, panel pinctrl/nora match, GPL-2.0, etc.). Original authorship (Catherine Frederick / coolguy for DTS+rpmcc; Felix Kaechele for rmi_i2c) is preserved.

Superseding PR: #57

Panels (Tianma + Ofilm) are in linux-panel-drivers#8. Happy to close this once #57 is preferred, or force-push onto this branch if that's cleaner for maintainers.

aneesh-pradhan · 2026-07-23T01:24:51Z

Upstream sends for the merge gate (barni2000 review) are now on-list via linux-arm-msm:

Gate 3 — rpmcc MSM8920 (binding + clk-smd-rpm):

Cover: https://lore.kernel.org/linux-arm-msm/20260723012415.48288-1-aneeshpradhan@acm.org/

Gate 4 — initial MSM8920 + perry DTS (trimmed mainline-first subset; depends on rpmcc):

Cover: https://lore.kernel.org/linux-arm-msm/20260723012431.48499-1-aneeshpradhan@acm.org/
In-Reply-To the rpmcc cover above.

Panel remains in linux-panel-drivers; IPA / QDSP6 audio / FG / modem deferred until their mainline dependencies exist. Happy to re-roll either series from review.
