[U-Boot] [PATCH 0/4 v4] DA8xx: USB support

[U-Boot] [PATCH 0/4 v4] DA8xx: USB support

[Ajay Kumar Gupta]

Hi,

These patch set have been created against uboot-ti/master branch.

Changes from previous version are,
	- Used C structure for DA8xx usb registers.

I didn't modify the alignment in include/usb.h as Nick suggested,
would wait for Remy Bohmer's comment on this.

Regards,
Ajay


Ajay Kumar Gupta (4):
  DA830: Add pinmux for USB0_DRVVBUS
  DA8xx: Add GPIO register definitions
  DA8xx: Add MUSB host support
  DA830: Add usb config

[U-Boot] [PATCH 3/4 v5] DA8xx: Add MUSB host support

[Gupta, Ajay Kumar]

Remy,

Any comment on DA8xx USB support patches?

These patch set depends on DA8xx base support patches which are available
only on uboot-ti tree.

Regards,
Ajay

[U-Boot] [PATCH 3/4 v5] DA8xx: Add MUSB host support

[Remy Bohmer]

Hi,

Okay let's check...

The last time I checked this series was not mainlined. Is it now?
It is always fun with these dependencies to other repos.. ;-)
If the series can be applied to current mainline, I will take them in...

Kind regards,

Remy

Right.

I can only repeat myself: patches shall be based on the mainline
"master" (or "next", if it exists) branch.


Best regards,

I believe it is in u-boot master as of now

It takes time for stuff in u-boot-ti to go to u-boot as we have an intermediate u-boot-arm :-)

We are doing things the way it is supposed to be done though :-)

So I believe

This I cannot confirm as the base patches were itself were going through a process of review at that point of time.

It applies to mainline except one. I will refresh the patch set and submit.
