0379c1f55b ASoC: OMAP: ams-delta: drop .set_bias_level callback
This functionality has already been implemented in the cx20442 codec
driver (commit f75a8ff67d, "ASoC: cx20442:
add bias control over a platform provided regulator"), no need to keep
it here duplicated.

Once done, remove the no longer used AMS_DELTA_LATCH2_MODEM_NRESET
symbol from the board header file and a call to the regulator_toggle()
helper function from the old API wrapper found in the board file.  While
being at it, simplify the way the modem .pm callback handles the
regulator and drop that helper function and its related consumer setup
completely.

Depends on patches 1/3 and 2/3 for clean apply and keep things working.

aabf31737a ARM: OMAP1: ams-delta: update the modem to use regulator API
After the CX20442 codec driver already takes care of enabling the codec
power for itself (commit f75a8ff67d,
"ASoC: cx20442: add bias control over a platform provided regulator"),
but before dropping the old bias control method from the Amstrad Delta
ASoC sound card file, which in fact keeps the modem power always on,
even on the ASoC device close for now, extend the modem setup with a
power management callback which toggles the regulator up to the modem's
needs, reusing the previously set up regulator consumer for this. Also,
drop the MODEM_NRESET pin setup from the modem initialization procedure,
as this operation was already ineffective since patch 1/3, and not
needed because the regulator is set up as initially enabled.

Depends on patch 1/3 "ARM: OMAP1: ams-delta: set up regulator over modem
reset GPIO pin" to apply cleanly.

ac2885df30 ARM: OMAP1: ams-delta: set up regulator over modem reset GPIO pin
The Amstrad Delta on-board latch2 bit named MODEM_NRESET, now available
as a GPIO pin AMS_DELTA_GPIO_PIN_NMODEM_RESET, is used to power up/down
(bring into/out of a reset state) two distinct on-board devices
simultaneously: the modem, and the voice codec. As a consequence, that
bit is, or can be, manipulated concurrently by two drivers, or their
platform provided hooks.

Instead of updating those drivers to use the gpiolib API as a new method
of controlling the MODEM_NRESET pin state, like it was done to other
drivers accessing latch2 pins, and still being vulnerable to potential
concurrency conflicts, or trying to solve that sharing issue with a
custom piece of code, set up a fixed regulator device on top of that
GPIO pin, with the intention of updating both drivers to manipulate that
regulator, not the GPIO pin directly.

Before the ASoC driver is updated and the modem platform data expanded
with a power management callback for switching its power, the
ams_delta_latch_write() function, which still provides the old API for
accessing latch2 functionality from not updated drivers, is modified to
toggle the regulator instead of the MODEM_NRESET GPIO pin.  A helper
function provided for balancing the regulator enable/disable operations,
together with the consumer data needed for tracking the regulator state,
will be removed once the drivers are updated.

Depends on patch series "ARM: OMAP1: ams-delta: replace custom I/O with
GPIO".

Tegra board updates. Most of the board updates for tegra30 and for some

c5444f3962 ARM: tegra: match SoC name not board name in DT board files
board-dt-tegra*.c should support any board using Tegra when booted using
device tree. Instead of explicitly listing all the supported boards,
which requires a kernel change for each new board, list the supported SoC
model instead.

Note that the board files do currently have explicit support for setting
up each board's pinmux. However, it's fairly likely that at least the
basic devices on any new board will work just fine as set up by the boot-
loader, and the pinmux data should be moving into device tree soon anyway.

da564a05b3 ARM: OMAP1: ams-delta: clean up init data section assignments
The main purpose of this patch is to fix several section mismatch
warnings from the board file and a few board specific drivers,
introduced with recent Amstrad Delta patch series, some of them rising
up only when building with CONFIG_MODULES not set.

While being at it, section tagging of all init data found in the board
file have been revised and hopefully corrected and/or optimized.

All the fixes are for the OMAP IOMMU driver. The first patch is the
 biggest one. It fixes the calls of the function omap_find_iovm_area() in
 the omap-iommu-debug module which expects a 'struct device' parameter
 since commit fabdbca instead of an omap_iommu handle. The
 omap-iommu-debug code still passed the handle to the function which
 caused a crash.
 The second patch fixes a NULL pointer dereference in the OMAP code and
 the third patch makes sure that the omap-iommu is initialized before the
 omap-isp driver, which relies on the iommu. The last patch is only a
 workaround until defered probing is implemented.

11407e5713 pxa/hx4700: Correct StrataFlash block size discovery
The HP iPAQ hx4700 has 128Mb of flash provided by two Intel StrataFlash devices.
The hx4700 platform configuration defines a single 128Mb flash resource,
resulting in the MTD physmap-flash driver probing the first device only and
presuming the second device is identical:

physmap platform flash device: 08000000 at 00000000
physmap-flash: Found 2 x16 devices at 0x0 in 32-bit bank. Manufacturer ID 0x000089 Chip ID 0x008816
physmap-flash: Found 2 x16 devices at 0x4000000 in 32-bit bank
<snip>
erase region 0: offset=0x0,size=0x10000,blocks=4
erase region 1: offset=0x40000,size=0x40000,blocks=255
erase region 2: offset=0x4000000,size=0x10000,blocks=4
erase region 3: offset=0x4040000,size=0x40000,blocks=255
physmap-flash: 2 set(s) of 2 interleaved chips --> 32 partitions of 4096 KiB

Unfortunately the two devices are not identical. The first has a device ID of
0x8816, identifying a bottom parameter device. The second has a device ID of
0x8813, identifying a top parameter device. By not probing the second device,
physmap-flash does not discover the correct block sizes.

This patch splits the configuration into two 64Mb flash resources, forcing
physmap-flash to probe both devices and thus discover the correct block sizes:

physmap platform flash device: 04000000 at 00000000
physmap-flash: Found 2 x16 devices at 0x0 in 32-bit bank. Manufacturer ID 0x000089 Chip ID 0x008816

3d468b6d60 ARM: kirkwood: add dreamplug (fdt) support.
Initially, copied guruplug-setup.c and did s/guruplug/dreamplug/g.
Then, switched to SPI based NOR flash.

After talking to Arnd Bergman, chose an incremental approach to adding
devicetree support.  First, we use the dtb to tell us we are on the
dreamplug, then we gradually port over drivers.

Driver porting will start with the uart (see next patch), and progress
from there.  Possibly, spi/flash/partitions will be next.

When done, board-dt.c will no longer be dreamplug specific, and dt's can
be made for the other kirkwood boards.
