please embedded this register data in the driver instead (not in the 
devicetree), matched against the compatible value.
See Frank's usb2phy driver for reference if needed.

Okay, I will move them to driver file next version, Thanks.

In other contexts I believe Heiko has requested that a suffix like
"_rst" not be present in the names of reset signals.  We already know
that this is a list of reset names so the "_rst" is redundant.

Just making sure: I saw a RESEND of your original version get posted,
but nothing that addresses Heiko's comments, right?

Also: note that bindings should be sent in the patch _before_ the
code.  So instead of:
  [1] phy: Add USB Type-C PHY driver for rk3399
  [2] Documentation: bindings: add dt doc for Rockchip USB Type-C PHY
  [3] drm/rockchip: vop: add cdn DP support for rk3399
  [4] Documentation: bindings: add dt documentation for cdn DP controller

You should have:
  [1] Documentation: bindings: add dt doc for Rockchip USB Type-C PHY
  [2] phy: Add USB Type-C PHY driver for rk3399
  [3] Documentation: bindings: add dt documentation for cdn DP controller
  [4] drm/rockchip: vop: add cdn DP support for rk3399

Yes, "_rst" is redundant.I will remove it next version.

The first patch is lack of a header file, so I resend the patches, and 
did not change anything, I will do them in V1 version.
And I will change the  sequence of patches, Thanks for your comments.
