Subject: [PATCH v7 0/5] Add MSM8939 SoC support with two devices

V7:
- Addresses all of Konrad's asks on V6
- Adds Konrad's RB for patch #3
Bootable: https://git.codelinaro.org/bryan.odonoghue/kernel/-/commits/linux-next-23-02-23-msm8939-nocpr
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

- Uses qcom,ids.h and QCOM_ID_SOCNAME for qcom,msm-id - 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

  commit a6f033938beb ("dt-bindings: msm: dsi-controller-main: Fix power-domain constraint") - Stephan
- Adds gcc dsi1pll and dsi1pllbyte to gcc clock list.

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.
