Hi Kishon,
Here's the series with fixed checkpatch warnings/checks.
Please pick it for phy/next.
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.
The tested branch[3] is based on torvald's master with greg's usb/usb-next
merged. Additionally the patches to get rpm up on msm8996 are also pulled
in.
Changes since v7:
- Fixed 'checkpatch --strict' alignment warnings/checks, and
added Stephen's Reviewed-by tag.
Changes since v6:
- Rebased on phy/next and *not* including phy grouping series[4].
- qusb2-phy: addressed Stephen's comment.
- Dropped pm8994_s2 corner regulator from QUSB2 phy bindings.
- qmp-phy: none on functionality side.
Changes since v5:
- Addressed review comments from Bjorn:
- Removed instances of readl/wirtel_relaxed calls from the drivers.
Instead, using simple readl/writel. Inserting a readl after a writel
to ensure the write is through to the device.
- Replaced regulator handling with regulator_bulk_** apis. This helps
in cutting down a lot of regulator handling code.
- Fixed minor return statements.
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.
