Like the EHCI driver, OHCI supports a large number of different platform
glue drivers by directly including them, which causes problems with
conflicting macro definitions in some cases. As more ARM architecture
specific back-ends are required to coexist in a single build, we should

Hi Alan,
These are the current patches from Manjunath, after I helped him address
the remaining review comments and found a few more in the process.
Unfortunately, Manjunath is currently on vacation and I will be away for

The ehci_shutdown function is used by the platform specific ehci backends
for at91, tegra and ps3. In order to turn any of these into separate
modules, we need to make this function globally visible and export it.

Ok.
Why can't you just use ci13xxx_platform_data?
It looks like you don't need a glue driver is drivers/usb/chipidea at
all, you can register ci_hdrc right from the ath79/dev-usb.c
You are right. I

The prepared memory for the qhead needs to be contiguos and 2K aligned.
We change the code from allocating extra buffer for every ep qhead to
one big area. This patch lowers the amount of code to prepare the
memory.

A static count of transfer descriptors was used everywhere in the driver
with the fixed number 5. This patch adds a define, named TD_PAGE_COUNT,
and replaces all users of this value. This way its possible to have only
one parameter to change and limit the amount of buffer pointers per TD.
Hi,
this series contains simples fixes and cleanup patches for
the chipidea udc. It is based on Alexander Shishkins ci-for-greg.

usb: chipidea: udc: only clear active and halted bits in qhead
usb: chipidea: udc: move ZLT flag change to ep_enable
It is not safe to truncate requests to the maximum possible size the
controller can handle with one td and to keep working. That patch fixes
that with proper error handling instead.

There is no need to call ep_queue unlocked inside the own driver. We
move its functionionality into an unlocked version.
This patch removes potential unlocked timeslots inside
isr_setup_status_phase and isr_get_status_response, in which the lock
got released just before acquired again inside
Its not necessary and also not specified in the datasheet to change the
ZLT flag before every ep_prime. This patch moves this to the ep_enable
and applies it only for non configuration endpoints.
