[PATCH 0/2] clk: qcom: add MSM8920 RPM clock controller support

[PATCH 0/2] clk: qcom: add MSM8920 RPM clock controller support

[Aneesh Pradhan]

Add MSM8920 support to the SMD RPM clock controller.

MSM8920 is essentially MSM8917 with MSM8953's modem stack, which adds
an IPA block. The new rpmcc table is MSM8917's clocks plus
RPM_SMD_IPA_{,A_}CLK (same IPA IDs already used by MSM8940; no new
dt-bindings/clock/qcom,rpmcc.h entries needed).

This series is split binding-then-driver so the shared clk-smd-rpm
changes can land via linux-arm-msm independently of the MSM8920 /
perry device trees (requested in msm89x7-mainline/linux#48 review).

Based on qcom/for-next (d36de2e50966). Applies cleanly there; also
applies to torvalds/master with a trivial yaml-schema context shift
(flat items vs oneOf) if preferred.

Hardware context: needed for initial MSM8920 + Motorola Moto E4 (perry)
upstream DTS follow-up. Fork PR tracking: msm89x7-mainline/linux#48.

Catherine Frederick authored the original fork series; this re-roll
keeps her From:/SoB and adds an [aneesh:] note + SoB for the split /
rebase onto the current for-next binding schema.

[PATCH 2/2] clk: qcom: smd-rpm: add MSM8920 support

[Aneesh Pradhan]

From: "Catherine Frederick (coolguy)" <serenity@floorchan.org>

MSM8920 is essentially MSM8917 with MSM8953's modem stack, which adds an
IPA (IP Accelerator) block. Add an msm8920 RPM clock table mirroring
msm8917's plus the IPA and IPA_A clocks, and register the
"qcom,rpmcc-msm8920" compatible.

Split out from the combined MSM8920 change so the shared clk-smd-rpm
driver can be reviewed and land via linux-arm-msm independently of the
device tree, as requested in review.

[PATCH 0/3] arm64: dts: qcom: initial MSM8920 and Motorola Moto E4 (perry)

[Aneesh Pradhan]

Initial upstream support for MSM8920 and the Motorola Moto E4 (perry).

Depends on the separate qcom,rpmcc-msm8920 clk series (binding +
clk-smd-rpm) for the MSM8920 rpmcc compatible used by msm8920.dtsi.

This is a trimmed mainline-first subset of msm89x7-mainline/linux#48,
rewritten so every phandle exists on qcom/for-next's msm8917 / pm8937 /
pmi8950 (the fork DT assumed richer SoC/PMIC nodes that are not
upstream yet).

Included: regulators, eMMC/SD, USB OTG (gpio-id extcon), keys, RMI4
touch + reset-gpios, BMA253 (i2c-gpio), WCNSS (wcn3660b), PMI8950 WLED.
Deferred follow-ups: DSI panel, IPA, QDSP6 audio, FG/smbcharger, modem.

DTB build verified: msm8917-motorola-perry.dtb + msm8920-motorola-perry.dtb.

[PATCH 2/3] arm64: dts: qcom: add initial MSM8920 device tree

[Aneesh Pradhan]

From: "Catherine Frederick (coolguy)" <serenity@floorchan.org>

MSM8920 is MSM8917 with a different RPM clock compatible (IPA clocks
present in rpmcc-msm8920). Start with the minimal SoC dtsi: include
msm8917.dtsi and override &rpmcc. IPA and other 8920-only peripherals
are deferred until their drivers/bindings are upstream.

Depends on the qcom,rpmcc-msm8920 binding/driver series.

[PATCH 3/3] arm64: dts: qcom: add initial Motorola Moto E4 (perry) support

[Aneesh Pradhan]

From: "Catherine Frederick (coolguy)" <serenity@floorchan.org>

Add MSM8917 and MSM8920 board files for the Motorola Moto E4 (perry)
sharing a common dtsi, shaped against in-tree msm8917-xiaomi-wingtech /
msm8937-xiaomi-land so every referenced label exists on mainline.

Initial subset: regulators, eMMC/SD, USB OTG (gpio extcon), gpio-keys,
Synaptics RMI4 touchscreen, BMA253 via i2c-gpio, WCNSS Wi-Fi
(qcom,wcn3660b), PMI8950 WLED.

Deferred (missing mainline SoC/PMIC nodes or drivers): DSI panel/MDSS,
IPA, QDSP6/WCD audio, PMI8950 FG/smbcharger, modem/ADSP/Venus remoteprocs.

Validated on XT1765 under postmarketOS with a fuller fork DT carry; this
is the trimmed upstream-first subset.

--- Patch [3]: [PATCH 3/3] arm64: dts: qcom: add initial Motorola Moto E4 (perry) support ---
commit f1e9e7f386e094ca8238575174ce1d5dde0b3f6c
Author: Catherine Frederick (coolguy) <serenity@floorchan.org>

arm64: dts: qcom: add initial Motorola Moto E4 (perry) support
    
This commit adds MSM8917 and MSM8920 board files for the Motorola Moto E4
(perry) sharing a common dtsi. It includes an initial subset of peripherals
such as regulators, eMMC/SD, USB OTG, and touchscreen, while deferring
peripherals lacking mainline drivers.

[Severity: Low]
This isn't a bug, but shouldn't these new device tree blobs be sorted
alphabetically within the Makefile? 

It looks like msm8917-motorola-perry.dtb is being inserted after the 
msm8917-xiaomi-* entries. Placing it before msm8917-xiaomi-riva.dtb would
follow the existing sorting convention and help minimize merge conflicts.

[PATCH v2 0/3] arm64: dts: qcom: initial MSM8920 and Motorola Moto E4 (perry)

[Aneesh Pradhan]

Initial upstream support for MSM8920 and the Motorola Moto E4 (perry).

Depends on the separate qcom,rpmcc-msm8920 clk series (binding +
clk-smd-rpm) for the MSM8920 rpmcc compatible used by msm8920.dtsi.

This is a trimmed mainline-first subset of msm89x7-mainline/linux#48,
rewritten so every phandle exists on qcom/for-next's msm8917 / pm8937 /
pmi8950 (the fork DT assumed richer SoC/PMIC nodes that are not
upstream yet).

Included: regulators, eMMC/SD, USB OTG (gpio-id extcon), keys, RMI4
touch + reset-gpios, BMA253 (i2c-gpio), WCNSS (wcn3660b), PMI8950 WLED.
Deferred follow-ups: DSI panel, IPA, QDSP6 audio, FG/smbcharger, modem.

DTB build verified: msm8917-motorola-perry.dtb + msm8920-motorola-perry.dtb.

Changes since v1:
- Sort Makefile DTB entries alphabetically: place
  msm8917-motorola-perry.dtb before msm8917-xiaomi-*, keeping
  msm8920-motorola-perry.dtb after the msm8917 block (Sashiko review
  on v1 patch 3/3).

[PATCH v2 2/3] arm64: dts: qcom: add initial MSM8920 device tree

[Aneesh Pradhan]

From: "Catherine Frederick (coolguy)" <serenity@floorchan.org>

MSM8920 is MSM8917 with a different RPM clock compatible (IPA clocks
present in rpmcc-msm8920). Start with the minimal SoC dtsi: include
msm8917.dtsi and override &rpmcc. IPA and other 8920-only peripherals
are deferred until their drivers/bindings are upstream.

Depends on the qcom,rpmcc-msm8920 binding/driver series.

[PATCH v2 3/3] arm64: dts: qcom: add initial Motorola Moto E4 (perry) support

[Aneesh Pradhan]

From: "Catherine Frederick (coolguy)" <serenity@floorchan.org>

Add MSM8917 and MSM8920 board files for the Motorola Moto E4 (perry)
sharing a common dtsi, shaped against in-tree msm8917-xiaomi-wingtech /
msm8937-xiaomi-land so every referenced label exists on mainline.

Initial subset: regulators, eMMC/SD, USB OTG (gpio extcon), gpio-keys,
Synaptics RMI4 touchscreen, BMA253 via i2c-gpio, WCNSS Wi-Fi
(qcom,wcn3660b), and PMI8950 WLED.

Deferred (missing mainline SoC/PMIC nodes or drivers): DSI panel/MDSS,
IPA, QDSP6/WCD audio, PMI8950 FG/smbcharger, modem/ADSP/Venus remoteprocs.

Validated on XT1765 under postmarketOS with a fuller fork DT carry; this
is the trimmed upstream-first subset.

Re: [PATCH v2 3/3] arm64: dts: qcom: add initial Motorola Moto E4 (perry) support

[sashiko-bot]

Thank you for your contribution! Sashiko AI review found 2 potential issue(s) to consider:
- [Medium] Critical pins for the touchscreen interrupt, sensor I2C bus, sensor interrupt, and regulator enable lack pinctrl configurations.
- [Medium] Battery design capacity is incorrectly specified for the hardware.

commit 456da8a21ca3d3b4649cf6cd9b340f36af9edbf2
Author: Catherine Frederick (coolguy) <serenity@floorchan.org>

arm64: dts: qcom: add initial Motorola Moto E4 (perry) support
    
Adds MSM8917 and MSM8920 board files for the Motorola Moto E4 (perry) sharing a
common dtsi. Includes regulators, eMMC/SD, USB OTG, gpio-keys, touchscreen,
IMU, Wi-Fi, and WLED.

[Severity: Medium]
Does the Moto E4 have a 4000 mAh battery? The design capacity here specifies
4000 mAh, but this device usually ships with a 2800 mAh battery. 

Could this incorrect capacity confuse the fuel gauge algorithms and lead to
inaccurate state-of-charge calculations?

[Severity: Medium]
Are we missing pinctrl configurations for the I2C bitbanging pins (gpio14,
gpio15) and the IMU interrupt pin (gpio41) below? 

Relying on bootloader state for these pins could lead to initialization
failures if they are left floating or improperly muxed.

[Severity: Medium]
Should the touchscreen interrupt pin (gpio65) be configured in this state as
well?

The touchscreen node explicitly uses it:

&blsp1_i2c3 {
	touchscreen@20 {
		interrupts = <65 IRQ_TYPE_EDGE_FALLING>;
		pinctrl-0 = <&ts_default>;
		reset-gpios = <&tlmm 64 GPIO_ACTIVE_LOW>;
	}
}

Missing pinctrl on this falling-edge interrupt could result in an interrupt
storm if the bootloader doesn't set the correct pin bias.

Do we know whether both MSM8917 and MSM8920 variants actually exist
in the wild? It's common practice for vendors to include an oversized
set of msm-ids in their downstream forks, either because of negligence
or because decisions change during product development.

You should definitely validate the changes you send on their own, atop

Please use memory-region instead of reg here
