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.

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.

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.

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.

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).

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.

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.
Signed-off-by: Catherine Frederick (coolguy) <serenity@floorchan.org>
[aneesh: rewrite against mainline msm8917/pm8937/pmi8950; drop fork-only
nodes; keep Makefile DTB entries alphabetically sorted]

Please don't thread different series together. No tooling does this, so
you would have to go out of your way to do it.
