[PATCH 0/6] i.MX51 RDU1 and Babbage USB fixes

[Andrey Smirnov]

Everyone:

These patches are a number of fixes I came up with while looking into
USB related problems on Babbage board.

Feedback is welcome!

Thanks,
Andrey Smirnov

[PATCH 1/6] clk: i.MX: Port Linux clock tree for i.MX51 and i.MX53

[Andrey Smirnov]

Existing clock tree code for i.MX5 in Barebox predates DT and is not
aware of it. This results in missing clocks on DT-based boards like
RDU1 and Babbage.

Port clock tree from Linux to resolve this proble. In order to avoid
breaking any other current users, change new code's compatiblity
string prefix from "fsl" to "barebox", so that converstion to new
clock could be done on per-board basis.

[PATCH 4/6] ARM: freescale-mx51-babbage: Add USBH1 PHY reset sequence

[Andrey Smirnov]

UPLI PHY connected to USBH1 on Babbage board seem to need a special
reset sequence in which STP signal gets asserted for a short period of
time. Without this sequnce running "usb" results in timeout and no USB
devices found.

Similar reset sequences can be found in Babbage board code in U-Boot
as well as efikamx_usb_init() in Barebox.

Re: [PATCH 1/6] clk: i.MX: Port Linux clock tree for i.MX51 and i.MX53

If a board changes the CCM compatible string in its internal device tree
this means it is no longer able to start a kernel with this device tree.

Also this means that the author of a new board actively has to change
the device tree to something barebox specific - something which is
forgotten too easy.

Last not least I think we'll never reach a state when the last board
is tested and converted so that we can remove the old code.

For these reasons I do not like the approach. I think we have to just
jump into the cold water and risk the regressions, like we always do.

I can test this addiitionally on the GuF Vincell and i.MX53 QSB if that
makes you more confident.

do 4/6 - 6/6 depend on the first three? If not I would apply them
independently.

All good points, no disagreement there. I was trying to be extra
conservative with v1 of the set, but just replacing old code would be
my preference as well, so that's what I'll do in v2.

Sure, I'll never say "no" to additional testing.
