This patch series enables Torrent PHY driver to support different input
reference clock frequencies. It also does the basic cleanup in order to
add support for multilink DP configurations. The multilink DP series at
[1] will be split in 2 parts and sent separately. This is part 1 of the
series.
Support for DP multilink configurations with register sequences will be
added in part 2 as a separate patch series after validation.
[1] https://lore.kernel.org/patchwork/cover/1410252/
Version History:
v2:
- Removed multilink DP support and register configuration patches
- Fixed v1 review comments
- Added Reviewed-by: Kishon Vijay Abraham I <kishon@ti.com> to patches
1/9, 3/9 and 7/9

Script checkpatch with --strict option gives message:
CHECK: Avoid CamelCase: <REF_CLK_19_2MHz>
CHECK: Avoid CamelCase: <REF_CLK_25MHz>
Fix this by removing CamelCase usage. No functional change.

Register configurations will be different based on reference clock value.
Prepare driver to support such multiple reference clock frequencies.

* [PATCH v2 4/9] phy: cadence-torrent: Configure PHY registers as a function of input reference clock rate

Torrent PHY supports multiple serdes standards with different input
reference clock frequencies. PHY register values differ based on the
reference clock rate. Add PHY input reference clock frequency as a
new dimension to select proper register configuration. No functional
change is intended.

Torrent PHY supports multiple serdes standards with different input
reference clock frequencies. PHY register values differ based on the
reference clock rate. Add PHY input reference clock frequency as a
new dimension to select proper register configuration. No functional
change is intended.

* [PATCH v2 5/9] phy: cadence-torrent: Add PHY registers for DP in array format

Cc: mparab, sjakhade, lokeshvutla
Add PHY registers for single link DP in array format to simplify
code and to improve readability. This supports already supported
frequencies for DP of 19.2MHz and 25MHz.

Torrent PHY driver currently supports single link DP configuration.
Prepare driver to support multilink DP configurations by adding
separate functions for common initialization sequence.
