[PATCHv7 0/5] ARM: remove the sub-node and deprecate supports-highspeed property for dwmmc.

[PATCHv7 0/5] ARM: remove the sub-node and deprecate supports-highspeed property for dwmmc.

[Jaehoon Chung]

Since used the mmc_of_parse(), didn't parse the sub-node.
So we can remove the sub-node, because almost SoC used the only one card per a host.
And supports-highspeed can be replaced to "cap-mmc/sd-highspeed" property.

Chnagelog V7:
	- Fixed typo and modified the commit message.
Changelog V6:
	- Fixed Wrong bit control for host's quirks and rename.
	- Add "Acked-by" for each SoC maintainers.
Changelog V5:
	- Rebased on v3.16-rc4.
	- Add Acked-by.
Changelog V4:
	- Fix the checkpatch error.
Changelog V3:
	- Fix the wrong bus-width value.
	- Use the slot->host->quirks instead of brq->quirks.
	- Add tested-by and reviewd-by.
Changelog V2:
	- Add the "mmc: dw_mmc: replace "disable-wp" from slot's quirks to host's quirk"

[PATCHv7 1/5] mmc: dw_mmc: modify the dt-binding for removing slot-node and supports-highspeed

[Jaehoon Chung]

Almost SoCs use one slot per host controller.
(Even if controller can support the multiple slot, Recommend to use one slot per host controller.)
Don't use the slot-node and deprecate the "supports-highspeed" property.
Instead, use the cap-mmc/sd-highspeed.

[PATCHv7 2/5] ARM: dts: exynos: unuse the slot-node and deprecated the supports-highspeed for dw-mmc

[Jaehoon Chung]

dw-mmc controller can support multiple slots.
But, there are no use-cases anywhere. So we don't need to support the
slot-node for dw-mmc controller.
And "supports-highspeed" property in dw-mmc is deprecated.
"supports-highspeed" property can be replaced to "cap-sd/mmc-highspeed".

[PATCHv7 3/5] ARM: dts: socfpga: unuse the slot-node and deprecated the supports-highspeed for dw-mmc

[Jaehoon Chung]

dw-mmc controller can support multiple slots.
But, there are no use-cases anywhere. So we don't need to support the
slot-node for dw-mmc controller.
And "supports-highspeed" property in dw-mmc is deprecated.
"supports-highspeed" property can be replaced to "cap-sd/mmc-highspeed".

It doesn't seem like it would be hard to include support for the old
binding (and just print a warning).  Then this could land ahead of the
device tree changes.

Generally I think we're supposed to keep support for old device trees
if possible (except in extreme cases).

Ok, I see. I will add the Warning message like this. ("Recommend not to use the slot-node...")
Then Developers can change the device-tree, right.

Today, i will send the patch. If you have any other comment, let me know, plz.
I want to merge this patch-set into 3.16.

That seems reasonable.

Right.  Then this can land even ahead of the dts changes and you could
change them one at a time (if you wanted) once you have the proper
acks.

I haven't done a full review, but generally this looked pretty sane to
me.  It seems like it might be too late for 3.16 but I'm no expert on
the subject.

Nit: 3x s/deprecated/deprecate/g to align tenses? (Sorry, I got

[PATCHv7 5/5] mmc: dw_mmc: replace "disable-wp" from slot's quirk to host's quirk

"Replace" is wrong here and in $subject. "Relocate"? "Move"?

> (Because the slot-node is removed at dt-file.)

"in dt-file"?

Still has "Almost SoCs" - I had suggested to insert "all", but I think
you mean "Most SoCs".

Since you said you are targeting 3.16 still, FYI Doug asked me to do the
same change for 3.17 in my Spring series for correctness reasons. So we
shouldn't have merge conflict there.

However, we are also dropping exynos5250-cros-common.dtsi, so at some
point the above changes will need to be merged into -snow.dts as
conflict resolution.

Similarly here, I am adding an exynos5410-odroidxu.dts file that will
need to get the same changes as -smdk5410.dts then.
