Hi Ben
Thank you for your hard work
This series adds support for UHS-I in sh_mobile_sdhi, partly implemented
in tmio_mmc. This does not yet include tuning for SDR-104, but SDR-50 now
works on the R8A7790 Lager board and another development board.
The pfc block needs to be reconfigured
Hi,
Sorry for late and thanks a lot for your test and suggestions! I have completed
the business travel and will check them in detail.
BRs,
Sun Yi

Hi,
I noticed in a kernel 4.0.7 that I loose CAN packets when an incoming
rsync transfer changes my eMMC or SD-Card image. I used CONFIG_FRACE
to find why this is the case, and came to this trace:
# tracer: preemptoff
#
# preemptoff latency trace v1.1.5 on 4.0.7

This is needed to get our regulators into hpm, to give enough power to our
sdhci cards to run at higher clockrates - e.g. hs200.

Hello,
I am trying to get a baytrail-t based convertible tablet working with
linux, using kernel 4.1 built for 32 bit Debian Jessie. I've made
good progress, making my Toshiba Click Mini work
sufficiently well to be useable with a USB wifi adaptor (the driver
for the integrated SDIO wifi makes it

The pfc block needs to be reconfigured from 3.3V to 1.8V signalling on

Currently tmio_mmc assumes that the input clock frequency is fixed and
only its own clock divider can be changed. This is not true in the
case of sh_mobile_sdhi; we can use the clock API to change it.
In tmio_mmc:

Based on work by Shinobu Uehara and Ben Dooks. This adds the voltage
switch operation needed for all UHS-I modes, but not the tuning needed
for SDR-104 which will come later.
The card_busy implementation is a bit of a guess, but works for me on
an R8A7790 chip.

Implement voltage switch, supporting modes up to SDR-50.

All the SHDIs can operate with either 3.3V or 1.8V signals, depending
on negotiation with the card.
Implement the {get,set}_io_voltage operations and set the related
capability flag for the associated pins.

The pfc in the R8A7790 (and probably others in the R-Car gen 2 family)
supports switching SDHI signals between 3.3V and 1.8V nominal voltage,
and the SD driver should do that when switching to and from UHS modes.
Add a flag for pins that have configurable I/O voltage and SoC
operations to get and
Change the clk_enable operation to take a pointer to the struct
tmio_mmc_host and have it set f_max. For consistency, also change the
clk_disable operation to take a pointer to struct tmio_mmc_host.
