This series adds the missing bit to enable the UHS, HS200 and DDR52 modes on the omap5 platforms (DRA7 and AM57).
It relies on the following series: * [PATCH v2 00/26] mmc: Add support for HS200 and UHS modes * [PATCH v2 0/5] mmc: omap_hsmmc: Add support for ADMA * [PATCH v3 0/2] power: Add a driver to handle the PBIAS cell of the TI SOCs
Enabling support for high speed modes on omap5 requires implementing: * io signal voltage selection * tuning support * pin configuration (IO delays)
The few last patches enable the high mode for all omap5 platforms except some for which we need to disable either the UHS or the HS200 because the volatge regulators on board would not allow using those modes. This is not a SOC limitation.
With this in place we observe significant improvements in the performances: on a DRA72 evm: eMMC HS200: 124 MB/s eMMC DDR52: 78 MB/s sd SDR104: 71 MB/s sd SDR50: 44 MB/s For the record, the original performances were: SD High speed: 18 MB/s MMC High speed: 18 MB/s
This series has been tested on: * DRA71-evm * DRA72-evm * DRA7x-evm * DRA76-evm * AM57x-evm * Beaglebone Black * AM335x evm * AM437x SK
