[PATCH v1 00/15] PHY: Update Cadence Torrent PHY driver with reconfiguration

[Yuti Amonkar]

This patch series applies to the Cadence SD0801 PHY driver. Cadence SD0801 PHY driver
is Torrent PHY driver for Display Port.Torrent PHY is a multiprotocol PHY supporting PHY 
configurations including Display Port,USB and PCIe. 
This patch series first adds display port configuration then updates the driver to make
it a generic Torrent driver and finally adds SoC platform dependent initialization.

The patch series has 15 patches which applies the changes in the below sequence 
1.  001-phy-cadance-dp-Add-DisplayPort-configuration-options
This patch adds generic DisplayPort API for configuring PHY.The parameters configured are
link rate, number of lanes, voltage swing and pre-emphasis.
2. 002-dt-bindings-phy-Convert-Cadence-MHDP-PHY-bindings-to-YAML
This patch converts the MHDP PHY device tree bindings to yaml schemas 
3. 003-phy-cadence-dp-Rename-to-phy-Cadence-Torrent
Rename Cadence DP PHY driver from phy-cadence-dp to phy-cadence-torrent 
4. 004-phy-cadence-torrent-Adopt-Torrent-nomenclature
Update private data structures, module descriptions and functions prefix to Torrent 
5. 005-phy-cadence-torrent-Add-wrapper-for-PHY-register-access
Add a wrapper function to write Torrent PHY registers to improve code readability.
6. 006-phy-cadence-torrent-Add-wrapper-for-DPTX-register-access
Add wrapper functions to read, write DisplayPort specific PHY registers to improve code
readability.
7. 007-phy-cadence-torrent-Refactor-code-for-reusability
Add separate function to set different power state values.
Use of uniform polling timeout value. Check return values of functions for error handling.
8. 008-phy-cadence-torrent-Add clock bindings 
Add Torrent PHY reference clock bindings. 
9. 009-phy-cadence-torrent-Add-19.2-MHz-reference-clock-support
Add configuration functions for 19.2 MHz reference clock support.Add register configurations
for SSC support.
10. 010-phy-cadence-torrent-Add-phy-lane-reset-support
Add reset support for PHY lane group.
11. 011-phy-cadence-torrent-Implement-phy-configure-APIs
Add PHY configuration APIs for link rate, number of lanes, voltage swing and pre-emphasis values.
12. 012-phy-cadence-torrent-Use-regmap
Use regmap for accessing Torrent PHY registers. Update register offsets. Abstract address 
calculation using regmap APIs.
13. 013-phy: cadence-torrent-Use-regmap-to-read-and-write-DPTX-PHY-registers
Use regmap to read and write DPTX specific PHY registers.
14. 014-dt-bindings-phy-phy-cadence-torrent-Add-platform-dependent-compatible-string
Add a new compatible string used for TI SoCs using Torrent PHY.
15. 015-phy-cadence-torrent-Add-platform-dependent-initialization-structure
Add platform dependent initialization data for Torrent PHY used in TI's J721E SoC.
