[PATCH 0/4] fix some issues for Rockchip usb2-phy and add rk322x SoCs' support

[Frank Wang]

These series of patches fix some issues for rockchip usb2-phy and amend
usb2-phy framework to support one phy which comprises with two host-ports.

In addition, this change also add rk322x usb2-phy support.

[PATCH 1/4] phy: rockchip-inno-usb2: add a delay after phy resume

[Frank Wang]

From: William Wu <william.wu@rock-chips.com>

When resume phy, it need about 1.5 ~ 2ms to wait for
utmi_clk which used for USB controller to become stable.

[PATCH 2/4] phy: rockchip-inno-usb2: increase otg sm work first schedule time

[Frank Wang]

From: William Wu <william.wu@rock-chips.com>

In rockchip-inno-usb2 phy driver, we use otg_sm_work to
dynamically manage power consumption for phy otg-port.
If the otg-port works as peripheral mode and does not
communicate with usb host, we will suspend phy.

But once suspend phy, the phy no longer has any internal
clock running, include the utmi_clk which supplied for
usb controller. So if we suspend phy before usb controller
init, it will cause usb controller fail to initialize.

Specifically, without this patch, the observed order is:
 1. unplug usb cable
 2. start system, do dwc2 controller probe
 3. dwc2_lowlevel_hw_enable()
    - phy_init()
     - rockchip_usb2phy_init()
      - schedule otg_sm_work after 2s
        put phy in suspend, and close utmi_clk
 4. dwc2_hsotg_udc_start() - fail to initialize the usb core

Generally, dwc2_hsotg_udc_start() can be called within 5s
after start system on Rockchip platform, so we increase the
the first schedule delay time to 6s for otg_sm_work afer usb
controller calls phy_init(), this can make sure that the usb
controller completes initialization before phy enter suspend.

[PATCH 3/4] phy: rockchip-inno-usb2: add one phy comprises with two host-ports support

[Frank Wang]

From: William Wu <william.wu@rock-chips.com>

At the current rockchip-inno-usb2 phy driver framework, it can
only support usb2-phy which comprises with one otg-port and one
host-port.

However, some Rockchip SoCs' (e.g RK3228, RK3229) usb2-phy comprises
with two host-ports, so we use index of otg id for one host-port
configuration, and make it work the same as otg-port host mode.

this adds a devicetree binding, so you should include devicetree people in
the recipient list:

Rob Herring <robh+dt@kernel.org>
Mark Rutland <mark.rutland@arm.com>
devicetree@vger.kernel.org

as they should Ack such binding additions.

devicetree compatibles should not contain wildcards, so please name that
"rockchip,rk3228-usb2phy"

here and in the driver as well.
