[PATCH/RTF 0/7] Add SDHI to r8a7796/salvator-x

[PATCH/RTF 0/7] Add SDHI to r8a7796/salvator-x

[Simon Horman]

Hi,

this patch set updates drivers, documentation and DT to
enable SDHI0 & 3 on the r8a7796/salvator-x. This includes
defining nodes for all available SDHI and GPIO devices.

I have boot-tested this which seems successful.
However, I do not have physical access to an r8a7796/salvator-x board
and the one that I have remote access to does not appear to have
any SD cards present. I would be grateful of any testing anyone
can provide.

Based on renesas-drivers-2016-08-09-v4.8-rc1

Provided for testing as the topic/r8a7796-sdhi branch in
my renesas tree on kernel.org.

Good point. I'll try and follow up on that.

On R-Car SoCs I believe all the SDHI instances have CD and WP support
in the SDHI hardware block. For some boards some SDHI instances may
not make use of all signals for instance in case of uSD WP signal.

Historically with SDHI the CD and WP pin availability depends on SDHI
instance for the particular SoC. On older mobile SoCs some SDHI
instances were intended to be used with an on-board SDIO module so the
hotplug / write protect signals were then omitted so no such PFC pins
existed. I've seen designs that used other GPIO signals for CD and WP
in such case.

I like the idea that the SoC specific DT device provides some shared
generic information about the SDHI channel and each board may opt-in
on certain board-specific properties such as CD and WP signals. Opt-in
for the WP signal is especially useful if we want to be able to
support both uSD and SD with the same DT device node. Before switching
to GPIO we had issues with uSD cards turning out to be read-only. If
CD/WP handling can be done consistently with the PFC signals then
that's of course fine, but I'm not sure the merit over that compared
to GPIO. Both CD and WP are not exactly in the hot path. =)

For R-Car I'm yet to see SDHI instances in power domains and PM is not
such a hot topic. On mobile SoCs we wanted to do our very best to turn
off the power domain the SDHI instance belongs to. It helps using GPIO
for CD in such case since the SDHI device can be runtime suspended and
the power domain powered down while the GPIO block still provides card
insert events. If we use the SDHI device CD signal for hot plug
notification then powering off the power domain may not be possible if
we still want notifications.
