[PATCHv9 0/5] ARM: remove the sub-node and deprecate supports-highspeed property for dwmmc.

[PATCHv9 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 with "cap-mmc/sd-highspeed" property.

Changelog V9:
	- Fix typos.
	- Relocated the warning message.
	- Change patch's sequence.
Changelog V8:
	- Add the warning message to notice that slot-node was removed.
	(As Doug's suggestion)
Changelog 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"

[PATCHv9 1/5] mmc: dw_mmc: Slot quirk "disable-wp" is deprecated.

[Jaehoon Chung]

Slot quirks "disable-wp" is deprecated.
Instead, use the host quirk "disable-wp".
(Because the slot-node is removed in dt-file.)

[PATCHv9 2/5] mmc: dw_mmc: modify the dt-binding for removing slot-node and supports-highspeed

[Jaehoon Chung]

Almost all 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.

[PATCHv9 3/5] ARM: dts: exynos: unuse the slot-node and deprecate 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 with "cap-sd/mmc-highspeed".

[PATCHv9 4/5] ARM: dts: socfpga: unuse the slot-node and deprecate 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 with "cap-sd/mmc-highspeed".

Thanks for taking my suggestion and making it backward compatible.
This looks great to me.  It tested this in both the backward
compatible way (with the warning) and the non-backward compatible way.
I think we should land and patch #2 ASAP and then we can land the rest
of the series as SoC maintainers see fit.

When I sent ack on exynos stuff, there was no conflict with my tree but 
happens it now.

Re: [PATCHv9 1/5] mmc: dw_mmc: Slot quirk "disable-wp" is deprecated.

[Jaehoon Chung]

Hi, All.

It seems too late that this patch-set is merged into linux-3.16.
Also there are some conflicts in device-tree. (I will remove the conflicts)
So if everybody is ok, I will rebase on linux-next after released linux-3.16.
At that time, i will send this patch-set to stable kernel, too.
how about?
And I want to know who can apply this patch-set(#3~#5).

I guess each SoC maintainer could take the changes to their work-area, once 
the core changes have landed in the mmc tree. So I would take the Rockchip 
patch, Kukjin the Exynos one and Dinh the socfpga patch.
