The Cypress c67x00 (EZ-Host/EZ-OTG) controllers are multi-role low/fullspeed
USB controllers. This patch series implements a HCD driver and shows the
work-in-progress status of a gadget driver.
I believe patch 1..3 are ready, and I would like to see them queued up for
mainline.
Changes since v10:
This patch add the core driver for the c67x00 USB OTG controller. The core
driver is responsible for the platform bus binding and creating either
USB HCD or USB Gadget instances for each of the serial interface engines
on the chip.
This driver does not directly implement the HCD or gadget behavio
This patch adds the low level support code for the Cypress c67x00 family of
OTG controllers. The low level code is responsible for register access and
implements the software protocol for communicating with the 16bit
microcontroller inside the c67x00 device.
Communication is done over the HPI int
This patch adds USB gadget support for the Cypress c67x00 family of devices.
This is work in progress and not ready to be committed yet. I'm posting this
to show how it fits with the rest of the driver and to collect feedback.
The driver works good enought to use g_serial, but there are still iss

This looks pretty cool ... but I don't want to create a dependency on
hrtimer.
It doesn't create such a dependency.
We use it unconditionally in the generic networking.
Please don't use platfor

Hi,

present in today's 2.6.25-git with CONFIG_NVRAM=m (instead of =y):

Hi,
I was a bit puzzled today when I came across
/sys/devices/platform/pmu-battery.0/power_supply/PMU battery 0/power
and thought to myself: why are there spaces in "PMU battery 0"? Wouldn't
../pmu-battery.0/power_supply/PMU_battery_0/power be feasible too? I find
it rather annoying to special c

Update. HW decided that the panic was bad. Added a flashing led to the
critical temperature.

You are correct. That was a cut and paste from warp.c which
specifically needs of_platform.h.

This adds a system call on 64-bit platforms for switching between
little-endian and big-endian modes that is much faster than doing a
prctl call. This system call is handled as a special case right at
the start of the system call entry code, and because it is a special
case, it uses a system call

This changes the definitions of the xchg and cmpxchg families of
functions in include/asm-powerpc/system.h to be marked __always_inline
rather than __inline__. The reason for doing this is that we rely on
the compiler inlining them in order to eliminate the references to
