Sending OS version for support of TPM2_ChangeEPS() is required only
for SPT FW (HMB version 2.0) and newer.
On older platforms the command should be just ignored by the firmware
but some older platforms misbehave so it's safer to send the command
only if required.

While the wakeup path seems to be set up, this waitqueue is actually
never used as no-one enqueues themselves on the list. As such, wakeups

The A64 MMC controllers need to set a "new timings" bit when a new rate is
set.
The actual meaning of that bit is not clear yet, but not setting it leads
to some corner-case issues, like the CMD53 failing, which is used to
implement SDIO packet aggregation.

Hi,
Here is a second attempt at getting the MMC controllers running, the first
having been done by Andre.
This has been tested on a board with one SDIO device (a Marvell WiFi chip)
and a Kingston eMMC with 1.8V IOs.
For SDIO, the HS DDR mode works just fine. There's a little bit of work to
get t
The MMC2 controller on the A64 is kind of a special beast.
While the general controller design is the same than the other MMC
controllers in the SoC, it also has a bunch of features and changes that
prevent it to be driven in the same way.
It has for example a different bus width limit, a differe
All the controllers can have a maximum frequency of 200MHz.
Since older SoCs cannot go that high, we cannot change the default maximum
frequency, but fortunately for us we have a property for that in the DT.
This also has the side effect of allowing to use the MMC HS200 mode for the
boards that s
The A64 only has a single set of pins for each MMC controller. Since we
already have boards that require all of them, let's add them to the DTSI.

Hi,
Thanks for reviewing!
Alexandre, could you please review this v3 and say when you plan to take
this driver in the cycle ?
Thanks,

The A64 has 3 MMC controllers, one of them being especially targeted to
eMMC. Among other things, it has a data strobe signal and a 8 bits data
width.
The two other are more usual controllers that will have a 4 bits width at
most and no data strobe signal, which limits it to

Declare reset_control_ops structures as const as they are only stored
in the ops field of a reset_controller_dev structure. This field is of
type const struct reset_control_ops *, so reset_control_ops structures
having this property can be declared as const.

checkpatch.pl complained about two unnecessary blank lines after an

of those warnings.
There are more issues pointed out by checkpatch.pl. Those require

Experience have shown that the using the autocalibration could severely
degrade the performances of the MMC bus.
Allwinner is using in its BSP a delay set to 0 for all the modes but HS400.
Remove the calibration code for now, and add comments to document our
findings.
