This patch series applies to the Cadence SD0801 PHY driver.
Cadence SD0801 PHY is also known as Torrent PHY. Torrent PHY
is a multiprotocol PHY supporting PHY configurations including
Display Port, USB and PCIe.

This patch series converts SD0801 PHY driver for DisplayPort into a
generic Torrent PHY driver, updates DisplayPort functionality with
reconfiguration support and finally adds platform dependent initialization
for TI J7 SoCs.

merged now, Thanks!

calculation using regmap APIs.
11. 011-phy: cadence-torrent-Use-regmap-to-read-and-write-DPTX-PHY-registers

12. 012-phy-cadence-torrent-Add-platform-dependent-initialization-structure
Add platform dependent initialization data for Torrent PHY used in TI's J721E SoC.
13. 013-phy: cadence-torrent-Add-support-for-subnode-bindings
Implement single link subnode support to the phy driver.

Version History:

v4:
- Add separate patch to remove old binding.
- Add new patch to add new binding in YAML format.
- Squashed "dt-bindings: phy: phy-cadence-torrent: Add platform dependent
  compatible string" with "dt-bindings: phy: Add Cadence MHDP PHY bindings
  in YAML format".
- Added SPDX dual license tag to YAML bindings.
- Updated resets property description and removed reset-names
  property.
- Added enum to cdns,phy-type property adding all the currently
  known phy-type values.
- Updated the child node resets property to support one reset
  per lane.
- Added default values for cdns,num-lanes and cdns,max-bit-rate properties.


v3:
- Removed "Add clock binding" patch from the series and merged it with
  "Convert-Cadence-MHDP-PHY-bindings-to-YAML" patch.
- Added reset and reset-names properties to YAML file.
- Updated dptx_phy reg entry as optional in YAML.
- Renamed reg-names from sd0801_phy to torrent_phy.
- Added subnode property for each group of PHY lanes based on PHY
  type to the YAML. Renamed num_lanes and max_bit_rate to cdns,num-lanes
  and cdns,max-bit-rate and moved it to subnode properties.
- Added cdns,phy-type property in subnode. Currently cdns,phy-type supports only
  PHY_TYPE_DP.
- Added subnode instance structure to the driver in reference to the dts change.
- Updated functions to read properties from child node instead of parent node.
- Added num_lanes as argument to the cdns_torrent_dp_run function.

v2:
- Remove patch [1] from this series and send for a separate review.
- Use enum in compatible property of YAML file.
- Remove quotes in clock-names property "refclk" -> refclk in YAML file.
- Add reg-names property to YAML file
- Add additionalProperties:false to YAML file.
- No change in the driver code.

This patch series is dependent on PHY DisplayPort configuration patch [1].
