Subject: [PATCH v4 0/2] phy: intel: Add Keem Bay USB PHY support

Hi.

Intel Keem Bay USB subsystem incorporates DesignWare USB3.1 controller,
an USB3.1 (Gen1/2) PHY and an USB2.0 PHY. It is a Dual Role Device
(DRD), operating as either a USB host or a USB device.

The patchset is tested on Keem Bay EVM.

Thank you.

Best regards,
Zainie

Changes since v3:
- Revise commit log message of the driver patch.
- In Kconfig, use depends on ARCH_KEEMBAY || COMPILE_TEST.
- Use genmask() to define USS_CPR_MASK.
- In keembay_regmap_config struct, specify .max_register.

Changes since v2:
- Remove dependency on OF in Kconfig.
- Remove header file linux/of.h, and add linux/mod_devicetable.h.
- Add comments for each usleep_range() usage, provide reason for the
  delay.
- Replace usleep_range(2, 10) with udelay(2), as per
  Documentation/timers/timers-howto.txt.
- In _probe(), remove variable np and use dev->of_node directly.

Changes since v1:
- Remove 2 patches that had been merged.
- Rebased to v5.10-rc3.
- Add Rob's Reviewed-by tag in the first patch.
- Use ARCH_KEEMBAY in Kconfig.
- Update #include header; remove <linux/of_address.h>, and add
  <linux/bits.h>.
- Remove unnecessary comments.
