Lothar Waßmann 96f3e25684 MXC IOMUX-V3 replace struct pad_desc with bitmapped cookie (step 2)
This patch actually replaces the 'struct pad_desc' with a u64 cookie
to facilitate adding platform specific pad_ctrl settings to an
existing pad definition.

So, instead of:
	iomux_v3_cfg_t power_key = MX51_PAD_EIM_A27__GPIO_2_21;
	power_key.pad_ctrl = MX51_GPIO_PAD_CTRL_2;
	mxc_iomux_v3_setup_pad(&power_key);
one can write:
	mxc_iomux_v3_setup_pad((MX51_PAD_EIM_A27__GPIO_2_21 & ~MUX_PAD_CTRL_MASK) | MX51_GPIO_PAD_CTRL_2);

Patch applies to branch 'imx-for-2.6.38' of git://git.pengutronix.de/git/imx/linux-2.6

Arnaud Patard (Rtp) 96886c4361 iMX51: introduce IMX_GPIO_NR
Currently, to define a GPIO number, we're using something like :

#define EFIKAMX_PCBID0         (2*32 + 16)

to define GPIO 3 16.

This is not really readable and it's error prone imho (note the 3 vs 2).
So, I'm introducing a new macro to define this in a better way. Now, the
code sample become :

#define EFIKAMX_PCBID0         IMX_GPIO_NR(3, 16)

v2:
- move to gpio.h
- add parens & spaces
- switch to IMX_GPIO_NR instead of MX51_GPIO_NR

The patch wraps 'struct pad_desc' in an opaque data type and
introduces macros to access the individual members.
This patch does not constitute any functional change!

The mxc-keypad device seems to be the result of an early and partial
merge of the keypad driver.  It's unused and there is no corresponding
driver available, so just remove it.

once in kernel/debug.S, and change the existing addruart macros to

This will also allow us to retreive the address of a uart for the MMU
state that we're not current in.

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.

===== begin semantic patch =====
// This adds an llseek= method to all file operations,
// as a preparation for making no_llseek the default.
//
// The rules are
// - use no_llseek explicitly if we do nonseekable_open
// - use seq_lseek for sequential files
// - use default_llseek if we know we access f_pos
// - use noop_llseek if we know we don't access f_pos,
//   but we still want to allow users to call lseek

Sascha Hauer 1ec1e82f25 dmaengine: Add Freescale i.MX SDMA support
This patch adds support for the Freescale i.MX SDMA engine.

The SDMA engine is a scatter/gather DMA engine which is implemented
as a seperate coprocessor. SDMA needs its own firmware which is
requested using the standard request_firmware mechanism. The firmware
has different entry points for each peripheral type, so drivers
have to pass the peripheral type to the DMA engine which in turn
picks the correct firmware entry point from a table contained in
the firmware image itself.
The original Freescale code also supports support for transfering
data to the internal SRAM which needs different entry points to
the firmware. Support for this is currently not implemented. Also,
support for the ASRC (asymmetric sample rate converter) is skipped.

I took a very simple approach to implement dmaengine support. Only
a single descriptor is statically assigned to a each channel. This
means that transfers can't be queued up but only a single transfer
is in progress. This simplifies implementation a lot and is sufficient
for the usual device/memory transfers.

Uwe Kleine-König 35bab0589b ARM: imx: change the way spi-imx devices are registered
Group soc specific data in a global struct instead of repeating it for
each call to imxXX_add_spi_imxX.  The structs holding the actual data
are placed in .init.constdata and so don't do much harm.  Compared to
the previous approach this reduces code size to call imx_add_spi_imx.

Uwe Kleine-König e780d2392d ARM: imx: prepare deprecating ARCH_MX1, MACH_MX2, MACH_MX21 and MACH_MX27
MACH_... is reserved for machine support, so use SOC as prefix, not MACH.

This introduces new symbols SOC_IMX1, SOC_IMX21 and SOC_IMX27.  They are
selected by the old symbols for now.  There is no substitute for MACH_MX2
as most usages of MX2 only means MX21 + MX27 but not MX25.

Later the choice about CPU and CPU family should go away and the individual
machines should select the right SOC symbol.  This is a precondition to
support more than one SOC in a single kernel image.

Uwe Kleine-König 9a763bfbe4 ARM: imx: get rid of mxc_gpio_init
This function is defined once for each imx family and so is in the way
when compiling a kernel for more than one SoC.

Uwe Kleine-König d109167b9c ARM: imx: rename mach dir for mx21 and mx27 to mach-imx
Finally all imx code should end up there, start with mach-mx2.  While
touching all files rename some files to use a hyphen instead of an
underscore.
