Previous: https://lore.kernel.org/lkml/20230222120411.55197-2-bryan.odonoghue@linaro.org/T/

V6:
- Adds Krzysztof's Ack for Square vendor addition - Krzysztof
- Incorporates all of Stephan's comments from V5, including
dropping CPR dummy given the dependent patch [1] has been merged, now.

V5:
- Adds Square as a vendor - Krzysztof

- typec_pd: usb-pd@38 - Krzysztof

- Drops gcc clock controller extension. It looks like phy0 actually
provides a PLL to phy1 for its byte clock. - Bryan, Krzysztof, Stephan

- Adds RB Konrad as indicated - Konrad

- wcnss VDDMX_AO -> VDDMX - Bjorn

- Adds dsi_phy0 as clock-parent to dsi1

- mdss interconnect drops Androidism "register-mem" - Stephan

- cpu power-domain. I've retained the "dummy" cpr reference to
satiate dtbs_check [1] but renamed &vreg_cpr_stub to remove any confusion
between now and when we finish off CPR on 8939.

V4:
- Adds Krzysztof's RB to snoc-mm
- Re-orders alphabetically missed nodes in previous iteration - Bjorn
- Adds LK address/size cells comment - Bjorn

- Left _AO for wcnss as downstream reference uses this - Bjorn/Bryan
- Uses qcom,ids.h and QCOM_ID_SOCNAME for qcom,msm-id - Bjorn
- Revises comment from "Regulator" to "Power supply" - Bjorn
- Leaves dummy power-domain reference in cpu defintion as this

- Relabels "cpu" to "CPU" to be more consistent with other dtsi - Bryan
- Moves msm8939 gcc to its own yaml file to capture 8939 specific form - Bryan

is a required property and the dt checker complains - Stephan/Bryan
- Removes CPR entries from qfprom - Stephan
- Left MDSS interconnects. I don't see a bug to fix here - Stephan/Bryan
- power-domain in MDSS - dropped its not longer required after
commit a6f033938beb ("dt-bindings: msm: dsi-controller-main: Fix power-domain constraint") - Stephan
- Adds gcc dsi1pll and dsi1pllbyte to gcc clock list.
Reviewing the silicon documentation we see dsi0_phy_pll is used to clock

Bjorn and Chanwoo picked up everything I need to unblock this series. ＼(^o^)／

- Moves xo_board to RPM/PMIC clock gated CXO, not including rpmcc: obvs - Konrad/Bjorn
- qcom,msm-id = <239 0> - left as in V2 valid according to Sony references - bod

out of reset - bod
- smem child node update - Konrad
- Whitespace updates - Konrad
- gpu no interconnect - Konrad - No bod
- 19.2 MHz dropped from timer@b020000 - Konrad
- Added vreg_dummy comment - Konrad

- l12 upper voltage raised to 3.3v since this is what the
downstream kernel says when I boot and interrogate it - bod

- sdhc@address - Discussed with Krzysztof and implemented as discussed
- snoc-mm fix - Discussed with Krzysztof implemented if:then:else:not
- dtc -I dtb -fs apq8039-t2.dtb prodcues

- Renamed type-c i2c port manager IC to "typec" - Krzysztof

/smsm/hexagon@1: Missing #address-cells in interrupt provider
Same output as other upstream and recently upstreamed SoCs
I left these alone for now

within address sorted nodes - Bjorn
- Drops use of 8916-pins - Bjorn

V1:
This series adds in MSM8939 SoC support with two supported devices.

- CPU
MSM8939 is a non-PSCI compliant device. As such in the downstreaming
shipped image custom code is used to bring non-boot cores out of reset.

This drop specifies the boot-method as spin-table instead and is
completely standard. To accomplish this, we rely on lk2nd.

https://github.com/msm8916-mainline/lk2nd/pull/142

- Serial
- i2c
- USB
- eMMC
- MDP/DSI
- WiFi
- Bluetooth

What's not included

- CPR
We have CPR working in a 4.19 kernel quite well but for now it feels like
putting the cart before the horse to gate the SoC and boards on CPR.

- Venus
I've been told this works but I haven't tried it myself and right now
consider it maybe working but probably not 100%.

- Sound
We have a copy-exactly from the 4.19 kernel here in the DTS.
I haven't run the sound through any sort of reasonable test.
Vincent Knecht has some PostmarketOS kernels which use a 5.17 version of
this DTS to get sound up so, I think sound is in good shape.

- CAMSS
There are slight differences between msm8916 and msm8939 for CAMSS. It
doesn't feel like tons of work but, right now it is work we haven't even
started.

- Devices
I've booted on the Square device obviously and this is my regular
hardware for upstream development. I've also booted on the Sony Xperia M4
Aqua including mutli-core bring-up, WiFi and ADB.
