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 patches have been tested on Dragon board db820c hardware with required set of dt patches and the patches to get rpm up on msm8996. Couple of other patches [1, 2] fixing DMA config for XHCI are also pulled in for testing. The complete branch is available in github [3]. Changes since v4: - Addressed comment to add child nodes for qmp phy driver. Each phy lane now has a separate child node under the main qmp node. - Modified the clock and reset initialization and enable methods. Different phys - pcie, usb and later ufs, have varying number of clocks and resets that are mandatory. So adding provision for clocks and reset lists helps in requesting all mandatory resources for individual phys and handle their failure cases accordingly. 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.
