[v3] initial usbdrd phy support for Exynosautov920 soc

[PATCH v3 9/9] arm64: dts: exynos: ExynosAutov920: add USB and USB SS combo phy nodes

Posted by Pritam Manohar Sutar 8 months ago

Update the USB 3.1 DRD controller and USB31DRD phy nodes to support
SS combo phy for this soc.

The USB 3.1 DRD controller has the following features:
* DWC3 compatible
* compliant with both USB device 3.1 and USB device 2.0 standards
* compliant with USB host 3.1 and USB host 2.0 standards
* supports USB device 3.1 and USB device 2.0 interfaces
* supports USB host 3.1 and USB host 2.0 interfaces
* full-speed (12 Mbps) and high-speed (480 Mbps) modes with USB device
  2.0 interface
* super-speed (5 Gbps) mode with USB device 3.1 Gen1 interface
* super-speed plus (10 Gbps) mode with USB device 3.1 Gen2 interface
* single USB port which can be used for USB 3.1 or USB 2.0
* on-chip USB PHY transceiver
* supports up to 16 bi-directional endpoints
* compliant with xHCI 1.1 specification

USB3.1 SSP+(10Gbps) is supported in this commit and SS phy in combo
phy only supports PIPE3 interface and it is added in index 0 of SS phy.
UTMI+ and PIPE3 PHY interfaces are specified in "phys" property,
UTMI+ (index 0 HS phy) and PIPE3 (index 0 SS phy).

I think at least patch 6 & 9 should be squashed.

Patch 6 and 9 are posted to add support for HS and SS phys in combo phy separately.
We will squash them in next version of patch-set (v4).

Yes. Changing lines which were just added is a strong hint, that
patchset is incorrectly organized.
