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

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.
