Subject: [PATCH 0/6] Add UHS mode support for TI's AM65x, J721e, J7200 boards

The following are driver and documentation patches to enable UHS modes for
TI's AM65x, J721e, and J7200 boards. Device tree and defconfig patches
will be sent in a separate series.

With the complete set, the following maximum modes will be supported:

am654x-evm,idk		- SDR104, HS200
j721e-common-proc-board	- DDR50, HS200
j7200-common-proc-board	- DDR50, HS200

These patches mainly add support for the software tuning algorithm[1]
needed for higher speed modes
