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
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
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
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
This patch adds HCD support for the Cypress c67x00 family of devices.

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 platform
Hi Jean,
-if ((err = f75375_probe(client)) 0)
+err = f75375_probe(client, NULL);

return 0;
These coding style cleanups don't belong to this patch (if they belong
anywhere - I don't much see the point)
I just wanted to make

Jochen, I'm a bit confused by the dependencies that exist - or not -
between these 7 patches you sent at once. I thought they had to be
applied in sequence but it seems not? And some of them should

General comment: if you're going to index arrays by enum
values, it's best to initialize them that way too. Else
you're expecting a particular optional policy for how the

PIKA Warp: Update platform code to support Rev B boards.
* Switched from 64M NOR/64M NAND to 4M NOR/256M NAND.
* Full DTM support including critical temperature.
* Added POST information.

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
