Subject: [PATCH v4 0/4] phy: USB and PCIe phy drivers for Qcom chipsets

This patch series adds couple of PHY drivers for Qualcomm chipsets.
a) qcom-qusb2 phy driver: that provides High Speed USB functionality.
b) qcom-qmp phy driver: that is a combo phy providing support for
   USB3, PCIe, UFS and few other controllers.

The patches are based on next branch of linux-phy tree.

These have been tested on Dragon board db820c hardware with
required set of dt patches on integration tree maintained by
Linaro landing team for Qualcomm [1].

Couple of other patches [2,3,4] for nvmem are also pulled in for testing.
Patch series fixing DMA config for XHCI [5] is also pulled in for testing.

Changes since v3:
 - Addressed review comments given by Rob and Stephen for qusb2 phy
   and qmp phy bindings respectively.
 - Addressed review comments given by Stephen and Bjorn for qmp phy driver.

Changes since v2:
 - Addressed review comments given by Rob and Stephen for bindings.
 - Addressed the review comments given by Stephen for the qusb2 and qmp
   phy drivers.

Changes since v1:
 - Moved device tree binding documentation to separate patches, as suggested
   by Rob.
 - Addressed review comment regarding qfprom accesses by qusb2 phy driver,
   given by Rob.
 - Addressed review comments from Kishon.
 - Addressed review comments from Srinivas for QMP phy driver.
 - Addressed kbuild warning.
