Greg Kroah-Hartman 89337e944e misc: delete mimc200 fram driver
To quote Mark:
	I think it's safe to delete the driver.

	The mimc200 unit is now basically obsolete and there'll be no
	new development on it.

Becides, it grabs the 0 misc minor number, when it never asked for it,
conflicting with the logitech bus mouse driver.

Paul Walmsley 464b500e37 avr32: favr-32: clk_round_rate() can return a zero upon error
Treat both negative and zero return values from clk_round_rate() as
errors.  This is needed since subsequent patches will convert
clk_round_rate()'s return value to be an unsigned type, rather than a
signed type, since some clock sources can generate rates higher than
(2^31)-1 Hz.

Eventually, when calling clk_round_rate(), only a return value of zero
will be considered a error.  All other values will be considered valid
rates.  The comparison against values less than 0 is kept to preserve
the correct behavior in the meantime.

The sysdev.h file should not be needed by any in-kernel code, so remove
the .h file from these random files that seem to still want to include
it.

The sysdev code will be going away soon, so this include needs to be
removed no matter what.

Jamie Iles 84e0cdb0a2 macb: unify at91 and avr32 platform data
Both at91 and avr32 defines its own platform data structure for
the macb driver and both share common structures though at91
includes a currently unused phy_irq_pin.  Create a common
macb_platform_data for macb that both at91 and avr32 can use.  In
future we can use this to support other architectures that use the
same IP block with the macb driver.

v2: rename eth_platform_data to macb_platform_data and allow at91_ether
to share the platform data with macb.

Arnd Bergmann 6038f373a3 llseek: automatically add .llseek fop
All file_operations should get a .llseek operation so we can make
nonseekable_open the default for future file operations without a
.llseek pointer.

The three cases that we can automatically detect are no_llseek, seq_lseek
and default_llseek. For cases where we can we can automatically prove that
the file offset is always ignored, we use noop_llseek, which maintains
the current behavior of not returning an error from a seek.

New drivers should normally not use noop_llseek but instead use no_llseek
and call nonseekable_open at open time.  Existing drivers can be converted
to do the same when the maintainer knows for certain that no user code
relies on calling seek on the device file.

The generated code is often incorrectly indented and right now contains
comments that clarify for each added line why a specific variant was
chosen. In the version that gets submitted upstream, the comments will
be gone and I will manually fix the indentation, because there does not
seem to be a way to do that using coccinelle.

Some amount of new code is currently sitting in linux-next that should get
the same modifications, which I will do at the end of the merge window.

Many thanks to Julia Lawall for helping me learn to write a semantic
patch that does all this.

Ben Nizette 92c548cd35 favr32: improve touchscreen response
The ezLCD+101 board (to which an favr-32 is fitted) has a long,
unshielded, nasty lead between the touch panel and the ads7843 touch
controller.  In order to get satisfactory response then, we need to
employ every noise-reduction trick in the driver's arsenal.  After
extensive fiddling I've found some good settings:

1) We keep vref on all the time to dramatically reduce settling times
(at the cost of a tiny increase in power consumption).

2) Despite 1 the settling time is still non-zero.  500uS is plenty of
time for the signals to settle

3) Despite 1 and 2 there's still a little bit of noise around.  By
setting a pen recheck delay we make the panel feel less touchy and
twitchy.

Someone with more time and patience myself might be able to tune this
numbers further but these settings are now perfectly acceptable for
normal use.

Tested on ezLCD+101 though should only improve response on other ezLCD+/
favr-32 boards too.

Mark Jackson c878b7d604 Fix MIMC200 board LCD init
This patch updates the LCD init code for the MIMC200 board.

V2 fixes a .yres typo and corrects an incorrect setup value
in the call to at32_add_device_lcdc()

Without this patch, the lcd setup is wrong and won't display images
correctly (if at all !!)

Alex Raimondi dd5e1339e5 avr32: Hammerhead board support
The Hammerhead platform is built around a AVR32 32-bit microcontroller
from Atmel.  It offers versatile peripherals, such as ethernet, usb
device, usb host etc.

The board also incooperates a power supply and is a Power over Ethernet
(PoE) Powered Device (PD).

Additonally, a Cyclone III FPGA from Altera is integrated on the board.
The FPGA is mapped into the 32-bit AVR memory bus. The FPGA offers two
DDR2 SDRAM interfaces, which will cover even the most exceptional need
of memory bandwidth. Together with the onboard video decoder the board
is ready for video processing.

This patch does include the basic support for the fpga device driver,
but not the device driver itself.
