Subject: [PATCH v5 0/7] sm8550: Add support for eUSB2 repeater

This patchset adds support for the eUSB2 repeater found in pmic PM8550B,
used along with SM8550. Since there is no dedicated generic framework
for eUSB2 repeaters, the most appropriate subsystem to model it is the
generic phy. This patchset also adds support for such repeater to the
eUSB2 PHY found in SM8550. Basically, the eUSB2 PHY will have its own
"phy" which is actually a repeater.

This patchset is based on the following patchset:
https://lore.kernel.org/all/20230208183421.2874423-1-abel.vesa@linaro.org/

Changes since v4:
 * added Krzysztof's R-b tag got patch #1 and A-b tag to patch #3

Changes since v3:
 * This time is a normal patchset, rather than an RFC

Changes since v2:
 * moved the bindings qcom,spmi-pmic patch before the repeater schema
   patch in order to avoid the repeater schema validation failure due to
   phy pattern property not being found in qcom,spmi-pmic schema

Changes since v1:
 * the repeater driver is implemented now as a PHY rather than adding
   a new generic framework for USB repeaters

  dt-bindings: phy: Add qcom,snps-eusb2-repeater schema file
  dt-bindings: mfd: qcom,spmi-pmic: Add pattern property for phy
  dt-bindings: phy: qcom,snps-eusb2-phy: Add phys property for the
    repeater
  phy: qcom: Add QCOM SNPS eUSB2 repeater driver
  arm64: dts: qcom: sm8550-mtp: Add eUSB2 repeater node
