5ce7d27d5c usb: chipidea: msm: Use posted data writes on AHB
This patch sets the AHBMODE to allow for posted data writes.  This
results in higher performance.

947c88592f usb: chipidea: remove flag CI_HDRC_REQUIRE_TRANSCEIVER
Now, USB PHY is mandatory for chipidea core, the flag
CI_HDRC_REQUIRE_TRANSCEIVER is useless.

ef44cb4226 usb: allow to supply the PHY in the drivers when using HCD
This patch modify the generic code handling PHYs to allow them to be
supplied from the drivers. This adds checks to ensure no PHY was already
there when looking for one in the generic code. This also makes sure we
do not modify its state in the generic HCD functions, it was provided by
the driver.

ea290056d7 usb: chipidea: msm: Use USB PHY API to control PHY state
PHY drivers keep track of the current state of the hardware,
so don't change PHY settings under it.

start address of the capability registers is not passed correctly to
udc_probe(). Fix this.

d268e9bc23 usb: chipidea: retire flag CI_HDRC_PULLUP_ON_VBUS
Currently, the controller only runs when the ci->vbus_active is true.
So the flag CI_HDRC_PULLUP_ON_VBUS is useless no longer.
If the user doesn't have otgsc, he/she needs to change ci_handle_vbus_change
to update ci->vbus_active.

8e22978c57 usb: chipidea: drop "13xxx" infix
"ci13xxx" is bad for at least the following reasons:
  * people often mistype it
  * it doesn't add any informational value to the names it's used in
  * it needlessly attracts mail filters

This patch replaces it with "ci_hdrc", "ci_udc" or "ci_hw", depending
on the situation. Modules with ci13xxx prefix are also renamed accordingly
and aliases are added for compatibility. Otherwise, no functional changes.
