[PATCH 0/6] Add UHS mode support for TI's AM65x, J721e, J7200 boards
From: Faiz Abbas
Date: Wed Sep 23 2020 - 06:52:46 EST
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
