Hi JJ,

This series adds the missing bits to enable the UHS and HS200 modes
for the TI platforms.
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 speed modes for the DRA7 platforms and
also take care of disabling those modes in the dts for the platforms that
cannot support either the UHS or the HS200 because the voltage regulators
on board would not allow using those modes (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 (dt and non-dt)
Changes in v2:
- rebased on top of u-boot/master
- enable the H200 and UHS support in the defconfigs of the DRA7 platforms
Changes in v3:
- in omap_hsmmc_set_clock(), if mmc->clock is zero, use the max divider.
- prefer the usage of the BIT() macro over the construct ( 1 << x )
- fixed build issue with omap3 platforms
Applied to u-boot-mmc. Sorry for late.
Best Regards,
Jaehoon Chung
Thanks Jaehoon
