Merge tag 'usb-5.2-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb

2019-05-08T17:03:52+00:00

Pull USB/PHY updates from Greg KH:
 "Here is the big set of USB and PHY driver patches for 5.2-rc1

  There is the usual set of:

   - USB gadget updates

   - PHY driver updates and additions

   - USB serial driver updates and fixes

   - typec updates and new chips supported

   - mtu3 driver updates

   - xhci driver updates

   - other tiny driver updates

  Nothing really interesting, just constant forward progress.

  All of these have been in linux-next for a while with no reported
  issues. The usb-gadget and usb-serial trees were merged a bit "late",
  but both of them had been in linux-next before they got merged here
  last Friday"

phy: rockchip-emmc: Allow to set drive impedance via DTS.

2019-04-17T08:42:58+00:00

The rockchip-emmc PHY can be configured with different
drive impedance values. Currenlty a value of 50 Ohm is
hard coded into the driver.

This patch introduces the DTS property 'drive-impedance-ohm'
for the rockchip-emmc phy node, which uses the value from the DTS
to setup the drive impedance accordingly.

phy: phy-rockchip-inno-usb2: drop reading the utmi-avalid property

2019-02-07T05:40:44+00:00

That property is no used in mainline and is not documented. The only
board using that property is the rk33-99-evb-rev1 and -rev2 in the
vendor kernel. The existence of a further -rev3 (which also looks way
better cared for compared rev1+2) indicates that the older ones are
probably some sort of preproduction models, where some wiring (on the soc
or board) may have gone wrong.

It is also not clear why this is a hardware-description or a DT
property, so, as noboby seems to care of this just drop reading that
property.

phy: Use of_node_name_eq for node name comparisons

2018-12-12T04:31:44+00:00

Convert string compares of DT node names to use of_node_name_eq helper
instead. This removes direct access to the node name pointer.

For instances using of_node_cmp, this has the side effect of now using
case sensitive comparisons. This should not matter for any FDT based
system which all of these are.

phy: rockchip-usb: add usb-uart setup for rk3188

2018-09-25T10:40:13+00:00

The rk3188 also supports bringing the uart2 out through
the usb dm+dp pins, so add the necessary setup for it.

rk3066 does not seem to support usb-uart functionality and this
particular phy was only used on older Rockchip socs, so this leaves
room for a bit of cleanup as well, as there most likely won't be new
additions in the driver.
