[PATCH v2 0/4] phy: USB and PCIe phy drivers for Qcom chipsets

From: Vivek Gautam
Date: Tue Nov 22 2016 - 07:03:02 EST

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 and UFS controllers.[1]

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

These have been tested on Dragon board db820c hardware with
required set of patches on integration tree maintained by
Linaro landing team for Qualcomm [2]. The QUSB2 phy driver
is also based on qfprom patch [3]:
[PATCH v2] nvmem: qfprom: Allow single byte accesses for read/write

Changes since v1:
- Moved device tree binding documentation to separate patches, as suggested
by Rob.
- Addressed review comment from Rob, 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.
- Please see patches 2 & 4 in the series for details on changes in v2.

[1] Currently the qcom-qmp phy driver supports only USB3 and PCIe
controllers. Later, we plan to add the UFS phy support as well to this.
