[ Upstream commit 49094d928618309877c50e589f23e639a3b0c453 ] Remove the temporary @mask_, this may cause build warning when use clang compiler for powerpc, but can't reproduce it when compile for arm64. the build warning is caused by: "warning: result of comparison of constant 18446744073709551615 with expression of type (aka 'unsigned long') is always false [-Wtautological-constant-out-of-range-compare]" More information provided in below lore link. After removing @mask_, there is a "CHECK:MACRO_ARG_REUSE" when run checkpatch.pl, but due to @mask is constant, no reuse problem will happen.

2022-07-05phy: phy-mtk-dp: Add driver for DP phyMarkus Schneider-Pargmann
This is a new driver that supports the integrated DisplayPort phy for mediatek SoCs, especially the mt8195. The phy is integrated into the DisplayPort controller and will be created by the mtk-dp driver. This driver expects a struct regmap to be able to work on the same registers as the DisplayPort controller. It sets the device data to be the struct phy so that the DisplayPort controller can easily work with it. The driver does not have any devicetree bindings because the datasheet does not list the controller and the phy as distinct units. The interaction with the controller can be covered by the configure callback of the phy framework and its displayport parameters.

The PHYA arch is updated, and doesn't support slew rate calibrate anymore on 7nm or advanced process, add a new version number to support it. Note: the FreqMeter bank is not used but reserved.
