The changes mainly involve configuring some extra glue registers in the flashSS which configure the Arasan controller. This series also adds support for UHS modes for eMMC. To allow UHS HS200/SD104 modes to function correctly, due to the tight timing constriants, support for delay management is also added. Two types of delay management are supported, static delay management and dynamic delay management, this delay management is only available on eMMC pads on stih410 and later silicon. This series has been tested with stih410-b2120 revd on eMMC and sd, at various clock speeds. As part of this testing a bug was also found in the upstream flexgen clock set_rate implementation (now fixed upstream). max-frequency = 200Mhz /dev/mmcblk0p1: Timing buffered disk reads: 270 MB in 3.02 seconds = 89.54 MB/sec max-frequency = 100Mhz root@debian-armhf:~# hdparm -t /dev/mmcblk0p1 /dev/mmcblk0p1: Timing buffered disk reads: 210 MB in 3.00 seconds = 70.00 MB/sec max-frequency = 50Mhz root@debian-armhf:~# hdparm -t /dev/mmcblk0p1 /dev/mmcblk0p1: Timing buffered disk reads: 118 MB in 3.00 seconds = 39.28 MB/sec It has also been tested on stih416-b2020 to ensure we have caused no regressions. Finally the dt documentation has been updated to reflect the changes in the driver code. Intrestingly it seems we are the first upstream platform to be using some of the uhs bindings such as sd-uhs-sdr104.

Do you confirm you didn't applied the DT patches? Thanks, Maxime
Kind regards Uffe
