[PATCH v2 0/3] Add USB support for Kaanapali

[PATCH v2 0/3] Add USB support for Kaanapali

[Krishna Kurapati]

Add support for the PHYs and controllers used for USB on Kaanapali SoCs.

V1 of this was a consolidated series of many functionlities on Kaanapali.
The first patch is patch-6 from v1 unchanges. The second and third patches
are parts of MTP and QRD specific changes (patches 14 and 16) and commit
text modified to indicate mtp and qrd specific changes are being made.

Ronak is the original author of the patches. Kept Jingyi's and mine SoB
(with no CDB) since we just rebased and send the patches in v1 and v2.

Since SoCCP changes are not acked yet, enabling only device mode.

Changes in v2:
- Sent USB specific changes instead of all MTP and QRD specific changes

Link to v1:

[PATCH v2 1/3] arm64: dts: qcom: kaanapali: Add USB support for Kaanapali SoC

[Krishna Kurapati]

From: Ronak Raheja <ronak.raheja@oss.qualcomm.com>

Add the base USB devicetree definitions for Kaanapali platform. The overall
chipset contains a single DWC3 USB3 controller (rev. 200a), SS QMP PHY
(rev. v8) and M31 eUSB2 PHY.

Following the woes on Hamoa, can the platform suspend and wake up
succesfully with the flattened DT node?

Huh??

You're creating a new node here - /pmih0108_e1_eusb2_repeater{}

I believe your intent was to override it by label

I can see that the usb port in the MTP support 'host' mode too. Should
this be 'otg'?

It's stated in the commit message: OTG requires glink, which is not
available yet.

If the issue is with switching between host vs device mode, isn't it
more useful to use "host" here? 'Host' mode does work on this device and
I use that to connect an ethernet dongle to ssh.

Another issue is VBUS. Without UCSI / pmic_glink control one will have
to set vbus regulators to always-on, which might be bad if it gets
plugged into another device.

Last, but not least, sadly enough of people ar still tied to the 'adb
push' mindset and workflow.

For all those reasons the USB is usually brought up as a peripheral
first, unless it comes together with the UCSI / TCPM implementation.

Why can't it be added as a part of this patchset?

I'm sure it clear to you what this mean, but for everyone else: what
SoCCP changes and what do you mean "acked"?
