[U-Boot] [PATCH 0/5] mx5: USB host support for mx51evk and mx53loco

[U-Boot] [PATCH 0/5] mx5: USB host support for mx51evk and mx53loco

[Wolfgang Grandegger]

This patches series provides USB host support for the mx51evk and
mx53loco. The generic ehci-mx5 interface is derived from ehci-mxc
and uses the header files of the ehci-fsl interface. The callback
board_ehci_hcd_init() allows to do board-specific setup when USB is
started.

Wolfgang.

Wolfgang Grandegger (5):
  mx5: add helper functions to enable USB clocks
  mx5: add helper function to retrieve the GPIO number
  mx5: add generic USB EHCI support for mx51 and mx53
  mx53loco: add end enable USB host support on port 1
  mx51evk: add end enable USB host support on port 1

Do we really need  to create a drivers/usb/host/ehci-mx5.c?

Can't mx5 USB support be included inside drivers/usb/host/ehci-mxc.c instead?

Hi,

isn't Jana already doing this kind of USB support for mx5 based on my old 
patches? You didn't notice?

Hi, I'm working on MX51 USB support based on some patches from Marek Vasut. 
It solves the problem in another way (uses structure-based offsets and generic
ULPI implementation I've written for this) and is probably more polished because
it's spent in the mailing list something like 2 months.
However, your patch supports both mx51 and mx53, so I think it would be nice
to find some way to get them together.
Last but not least, I'm sorry that I didn't respond to your first e-mail,
but I had to study for a test and hadn't time to look at your patch better.

Regards,
Jana Rapava

it could be included into ehci-mxc.c using #ifdef's, of course. Would
that be the better solution?

Well, I already responded on Jana's patches and presented my ideas here:

  http://marc.info/?l=u-boot&m=132067806107887&w=2

Unfortunately, only the mails with subject "[PATCH] ..." get enough
attention ;-).

The big difference to Jana's patch is that he uses a board-specific
implementation (ehci_hcd_init() is in board specific code). I think we
should share some code.

The structure-based offsets are nice. For my boards I do not need
special ULPI support and therefore it's a clearly separated interface.

I think we should share some code, especially the ehci_hcd_init()
callback. If my recent patch series, I call a board-specific
board_hcd_init() in the common ehci_hcd_init() which would be fine for
your hardware as well.

No problem, you are welcome.

Unfortuantely, the existing interface ehci for the mxc is kind of mess
and if derived from various existing interfaces, mainly ehci-fsl from
u-boot and ehci-mxc from linux.

I'm going to comment on your recent patch series now...

Wolfgang.

See my patches ;-). Well, maybe it's more straight forward if we try to
get my patches for the MX51/53 boards accepted first and then Jana could
then use the negotiated interface. But also vise versa is fine for me.
