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.

5a3ff8473c ARM: OMAP: irqs: Fix NR_IRQS value to handle PRCM interrupts
The following commit: 2f31b51659
Author: Tero Kristo <t-kristo@ti.com>
Date:   Fri Dec 16 14:37:00 2011 -0700

    ARM: OMAP4: PRM: use PRCM interrupt handler

introduced the PRCM interrupt handler and thus the need
for 64 more interrupts. Since SPARSE_IRQ is still not fully
functional on OMAP, the NR_IRQS needs to be updated to avoid
the failure that happen during irq_alloc_descs call inside
the PRCM driver:

[    0.208221] PRCM: failed to allocate irq descs: -12

Later the mux framework is then unable to request an IRQ from
the PRCM interrupt handler.

[    1.802795] mux: Failed to setup hwmod io irq -22

Fix that by adding 64 more interrupts for OMAP2PLUS config.

2ec1fc4e16 ARM: OMAP4: Move the barrier memboclk_steal() as part of reserve callback
arm_memblock_steal() is not suppose to be used outside ->reserve callback.
OMAP barrier errata code was using it outside reserve callback and hence
it was broken.

Move the allocation as part of ->reserve callback to fix the it.

716a3dc200 ARM: Add arm_memblock_steal() to allocate memory away from the kernel
Several platforms are now using the memblock_alloc+memblock_free+
memblock_remove trick to obtain memory which won't be mapped in the
kernel's page tables.  Most platforms do this (correctly) in the
->reserve callback.  However, OMAP has started to call these functions
outside of this callback, and this is extremely unsafe - memory will
not be unmapped, and could well be given out after memblock is no
longer responsible for its management.

So, provide arm_memblock_steal() to perform this function, and ensure
that it panic()s if it is used inappropriately.  Convert everyone
over, including OMAP.

As a result, OMAP with OMAP4_ERRATA_I688 enabled will panic on boot
with this change.  Mark this option as BROKEN and make it depend on
BROKEN.  OMAP needs to be fixed, or 137d105d50 (ARM: OMAP4: Fix
errata i688 with MPU interconnect barriers.) reverted until such
time it can be fixed correctly.

8d09a1bb31 input: serio: ams-delta: toggle keyboard power over GPIO
Don't use Amstrad Delta custom I/O functions once GPIO interface is
available for the underlying hardware.

While requesting and initializing GPIO pins used, also take care of one
extra pin KEYBRD_DATAOUT which, even if not used by the driver, belongs
to the device and affects its functioning.

Once done, move the driver initialization back to the device_initcall
level, reverting the temporary chane introduced with patch 1/7 "ARM:
OMAP1: ams-delta: register latch dependent devices later".  That change
is no longer required once the driver takes care of registering used
GPIO pins, and it's better to initialize the device before others using
the latch2 based GPIO pins, otherwise a garbage is reported on boot,
perhaps due to random data already captured by the FIQ handler while the
keyboard related latch bits are written with random values during
initialization of those other latch2 dependent devices.

937eb4bb00 ARM: OMAP1: ams-delta: convert latches to basic_mmio_gpio
Once ready, ams-delta specific device drivers currently calling custom
ams_delta_latch[12]_write() functions can be updated to call generic
gpio_set_value() instead, which will make them less platform dependent.
Even more, some custom ams-delta only drivers can perhaps be dropped
from the tree after converting selected ams-delta platform devices to
follow generic GPIO based device models.

The latch_gpios[] table is initially filled with all latch1 and latch2
GPIO pins in order to register and initialize them from the board file
until those are handled by respective existing device drivers (leds,
nand, lcd, serio, asoc, serial). That table will get almost empty after
the transision process is completed, holding only pins not used by any
drivers / connected to unused devices, in order to initialize them from
the board file for power saving purposes.

The new ams_delta_latch_write() function is a unified replacement for
those removed ams_delta_latch[12]_write(), and serves as a temporary
wrapper over gpio_set_value(), providing the old API for those not yet
updated device drivers, and will be removed after all custom drivers are
converted or replaced.

2f0778afac ARM: 7205/2: sched_clock: allow sched_clock to be selected at runtime
sched_clock() is yet another blocker on the road to the single
image. This patch implements an idea by Russell King:

http://www.spinics.net/lists/linux-omap/msg49561.html

Instead of asking the platform to implement both sched_clock()
itself and the rollover callback, simply register a read()
function, and let the ARM code care about sched_clock() itself,
the conversion to ns and the rollover. sched_clock() uses
this read() function as an indirection to the platform code.
If the platform doesn't provide a read(), the code falls back
to the jiffy counter (just like the default sched_clock).

This allow some simplifications and possibly some footprint gain
when multiple platforms are compiled in. Among the drawbacks,
the removal of the *_fixed_sched_clock optimization which could
negatively impact some platforms (sa1100, tegra, versatile
and omap).

Tested on 11MPCore, OMAP4 and Tegra.

aacf094128 ARM: OMAP2+: hwmod: Add a new flag to handle hwmods left enabled at init
An hwmod with a 'HWMOD_INIT_NO_IDLE' flag set, is left in
enabled state by the hwmod framework post the initial setup.
Once a real user of the device (a driver) tries to enable it
at a later point, the hwmod framework throws a WARN() about
the device being already in enabled state.

Fix this by introducing a new internal flag '_HWMOD_SKIP_ENABLE' to
identify such devices/hwmods. When the device/hwmod is requested to be
enabled (the first time) by its driver/user, nothing except the
mux-enable is needed. The mux data is board specific and is
unavailable during initial enable() of the device, done by the
framework as part of setup().

A good example of a such a device is an UART used as debug console.
The UART module needs to be kept enabled through the boot, until the
UART driver takes control of it, for debug prints to appear on
the console.

abc2d54563 ARM: OMAP: hwmod: add support for selecting mpu_irq for each wakeup pad
By default all registered pads will trigger mpu_irqs[0]. Now there is
an API for selecting used mpu_irq on pad basis, which can be used to
trigger different irq handlers for different pads in the same hwmod.
Each pad that requires its interrupt to be re-routed this way must
have a separate call to omap_hwmod_pad_route_irq(hwmod, pad, irq).

6c984b066d ARM: OMAP: USBHOST: Replace usbhs core driver APIs by Runtime pm APIs
The ehci and ohci drivers does not use the APIs of the usbhs
core driver; the runtime pm APIs are used for clock
enable/disable. Since usbhs is parent platform device of the
ehci and ohci devices, the runtime apis indirectly uses the
usb hs core device as input parameter to for clock functions.

4bf90f6573 ARM: OMAP: hwmod data: Add support for AM35xx UART4/ttyO3
Add hwmod support to enable access to UART4 of the AM35xx series of
chips.  The UART4 device referenced from the TRM will show up as ttyO3.

This was tested on an AM3505.

2fd149645e ARM: OMAP2+: UART: Remove omap_uart_can_sleep and add pm_qos
Omap_uart_can_sleep function blocks system wide low power state until
uart is active remove this func and add qos requests to prevent
MPU from transitioning.

Keep qos request to default value which will allow MPU to transition
and while uart baud rate is available calculate the latency value
from the baudrate and use the same to hold constraint while uart clocks
are enabled, and if uart is auto-idled the constraint is updated with
default constraint value allowing MPU to transition.

Qos requests are blocking notifier calls so put these requests to
work queue, also the driver uses irq_safe version of runtime API's
and callbacks can be called in interrupt disabled context.
So to avoid warn on slow path warning while using qos update
API's from runtime callbacks use the qos_work_queue.

During bootup the runtime_resume call backs might not be called and runtime
callback gets called only after uart is idled by setting the autosuspend
timeout. So qos_request from runtime resume callback might not activated during
boot if uart baudrate is calculated during bootup for console uart, so schedule
the qos_work queue once we calc_latency while configuring the uart port.

Flush and complete any pending qos jobs in work queue while suspending.

a9e210e0b7 ARM: OMAP2+: UART: Make the RX_TIMEOUT for DMA configurable for each UART
When using DMA there are two timeouts defined. The first timeout,
rx_timeout, is really a polling rate in which software polls the
DMA status to see if the DMA has finished. This is necessary for
the RX side because we do not know how much data we will receive.
The secound timeout, RX_TIMEOUT, is a timeout after which the
DMA will be stopped if no more data is received. To make this
clearer, rename rx_timeout as rx_poll_rate and rename the
function serial_omap_rx_timeout() to serial_omap_rxdma_poll().

The OMAP-Serial driver defines an RX_TIMEOUT of 3 seconds that is
used to indicate when the DMA for UART can be stopped if no more
data is received. The value is a global definition that is applied
to all instances of the UART.

Each UART may be used for a different purpose and so the timeout
required may differ. Make this value configurable for each UART so
that this value can be optimised for power savings.

c86845db77 ARM: OMAP2+: UART: Allow UART parameters to be configured from board file.
The following UART parameters are defined within the UART driver:

1). Whether the UART uses DMA (dma_enabled), by default set to 0
2). The size of dma buffer (set to 4096 bytes)
3). The time after which the dma should stop if no more data is received.
4). The auto suspend delay that will be passed for pm_runtime_autosuspend
    where uart will be disabled after timeout

Different UARTs may be used for different purpose such as the console,
for interfacing bluetooth chip, for interfacing to a modem chip, etc.
Therefore, it is necessary to be able to customize the above settings
for a given board on a per UART basis.

This change allows these parameters to be configured from the board file
and allows the parameters to be configured for each UART independently.

If a board does not define its own custom parameters for the UARTs, then
use the default parameters in the structure "omap_serial_default_info".
The default parameters are defined to be the same as the current settings
in the UART driver to avoid breaking the UART for any cuurnelty supported
boards. By default, make all boards use the default UART parameters.
