[PATCH RESEND 0/4] ARM: EXYNOS: Add s3c-hsotg support for Exynos4210 and S5PV210 boards

[Lukasz Majewski]

This patch series adds S3C-HSOTG UDC support for Exynos4210 and S5PV210 based targets; namely
 Universal_C210, Nuri and GONI.

Tested HW:
- Exynos4210 NURI target rev.1
- Exynos4210 Universal_C210 target rev.0
- S5PV210 GONI target

Dependencies:
- usb:hsotg:samsung USB S3C-HSOTG driver fixes and code cleanup
  patches, which have been already pulled to usb for-next branch.

http://permalink.gmane.org/gmane.linux.usb.general/62101

Those patches are enabling this UDC driver on GONI, NURI and Universal_C210 targets

Hi Lukasz,

I have small comments on this.

Do we _really_ need above udelay(80)?

As I know, we only need it in the phy1_init() for EHCI and we don't need it
here.

I think, this should be exynos4210_usb_phy0_init(pdev), because this is
available on only exynos4210 not exynos4x12 and exynos5.

Same as above.

If you're ok on my comments, could you please update it as soon as possible
for v3.5?

Thanks.

Thanks for applying patches.

Regarding the build error:

After applying following patches on top of yours for next
(linux-samsung/for-next) the problem with build error doesn't appear
anymore.

Link to USB HSOTG patch series:

http://permalink.gmane.org/gmane.linux.usb.general/62101
"usb:hsotg:samsung USB S3C-HSOTG driver fixes and code cleanup"

Moreover those patches have been already applied to Greg-KH's usb-next
branch an will be released with 3.5 kernel.

Yes, I know why the build error happens and I can't apply them which are 
already in usb tree in my tree now. I'm thinking this series should be 
sent to upstream via usb tree together so if required, I will ask Greg 
and Felipe to do it.

Yeah, I know. But the problem is that if arm-soc tree is merged before 
usb tree, same build error will be happened in mainline so I was 
thinking how we can avoid that. If your effort is required, let you know.

Thanks.

Kukjin,

Are you planning to queue this patchset for 3.5? If so, I have one patch
for enabling support on Origen board, which I would like to add on top
of these patches.

Please let me know about your plan.

[PATCH RESEND 0/4] ARM: EXYNOS: Add s3c-hsotg support for Exynos4210 and S5PV210 boards

[Lukasz Majewski]

This patch series adds S3C-HSOTG UDC support for Exynos4210 and S5PV210 based targets; namely
 Universal_C210, Nuri and GONI.

Tested HW:
- Exynos4210 NURI target rev.1
- Exynos4210 Universal_C210 target rev.0
- S5PV210 GONI target

Dependencies:
- usb:hsotg:samsung USB S3C-HSOTG driver fixes and code cleanup
  patches, which have been already pulled to usb for-next branch.

http://permalink.gmane.org/gmane.linux.usb.general/62101

Those patches are enabling this UDC driver on GONI, NURI and Universal_C210 targets
