Subject: [PATCH v8 0/5] Add SS/HS-USB changes for Qualcomm SM8150 chipset

This series adds support for the Synopsis 7nm HSPHY USB driver being
used in QCOM chipsets.  The HSPHY register map differs compared to 
other PHY revisions.  In addition, modifications and updates are done
to the QMP driver to add new registers/offsets, and to update the
initialization sequence for enabling the SSUSB path on SM8150.

Changes in v8:
 - Fix checkpatch warnings about characters per line.
 - Rebase to linux-phy/next branch

Reviewed-by: Vinod Koul <vkoul@...nel.org>

Changes in v7:
 - Use _relaxed() variants for writel/readl calls in
   phy-qcom-snps-femto-v2.c
 - Remove comments in the phy init function
 - Use devm_platform_ioremap_resource instead of devm_ioremap_resource
 - Fix chipset naming in Kconfig
 - Address minor fixups in the YAML file (remove status in example, fix
   "Hi-speed" to "High-speed", add a newline at the end)

Changes in v6:
 - Addressed coding style errors in phy-qcom-snps-femto-v2.c

Changes in v5:
 - Reorganize IF check for when to use the proper PWRDOWN CTRL offset
 - Rename UFS specific offset definitions in the QMP PHY driver to clearly
   denote they are UFS specific
 - Rename the phy-qcom-snps-7nm driver to phy-qcom-snps-femto-v2

Changes in v4:
 - Fix POWERDOWN offset for QMP PHY exit routine, and check for
   has_phy_dp_com_ctrl instead of !has_phy_com_ctrl

Changes in v3:
 - Use devm_reset_control_get_exclusive instead of referencing index for
   reset handle

Changes in v2:
 - Fixed YAML errors caught by dt_binding_check
