*) Add support in PHY core to create link between PHY consumer and PHY
provider
*) Add DisplayPort PHY configuration set to be used for negotiating the
configurations to be used between DisplayPort controller and
DisplayPort PHY
*) Add PHY wrapper driver (configure inputs to Cadence Sierra PHY) for
TI's J721E SoC and adapt Cadence Sierra PHY driver to be used for
J721E SoC (Supports USB and PCIe)
*) Add PHY driver for eMMC PHY in Intel LGM SoC
*) Add PHY support for 7216 and 7211 Broadcom SoCs which uses the new
Synopsys USB Controller
*) Add support for 16nm SATA PHY present in Broadcom 7216 SoC
*) Fix lost packet issue, fix MDIO from getting inaccessible, fix
occasional transaction failures, fix USB driver from crashing in
Broadcom USB PHY driver
*) Fix missing PCS SW reset in UFS PHY of Qualcomm SM8150
*) Use "struct phy_configure_opts_mipi_dphy" to pass parameters from
display controller to rockchip-inno-dsidphy
*) Other cleanups including compile testing for some of the PHY drivers,
fixing Kconfig indentation, duplicate writes in drivers etc.,
