25db711df3 gpio/omap: Fix IRQ handling for SPARSE_IRQ
The driver is still relying on internal OMAP IRQ defines that
are not relevant anymore if OMAP is built with SPARSE_IRQ.

Replace the defines with the proper IRQ base number.
Clean some comment style issue.
Remove some hidden and ugly cpu_class_is_omap1() inside the
gpio header.

cea6b94212 ARM: OMAP3+: SmartReflex: use voltage domain name in device attributes
To set sr ntarget values for all volt_domain,
volt_table is retrieved by doing a look_up of 'vdd_name'
field from omap_hwmod but voltage domain pointer does not
belong to omap_hwmod and is not used anywhere else.
As a part of voltage layer and SR Layer clean up volt
pointer is removed from omap_hwmod and added in dev
attributes of SR. The value of the field must match
the voltage domain names for the binding to be effective.

Tested on OMAP3630 SDP, OMAP3530 Beagleboard and
OMAP4430 SDP Board.

0379c1f55b ASoC: OMAP: ams-delta: drop .set_bias_level callback
This functionality has already been implemented in the cx20442 codec
driver (commit f75a8ff67d161b5166a2c2360bb2ffaefd5eb853, "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.

    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.

acea7c7b81 ARM: OMAP2+: Limit omap_read/write usage to legacy USB drivers
Drivers should no longer use omap_read/write functions
but instead use ioremap + read/write functions.

As some USB legacy code is still shared between omap1 and
omap2420, let's limit the omap_read/write to plat/usb.h.

Note that the long term fix is to update the drivers to
use ioremap and read/write functions. That can now be
done as a separate patch series that is limited to the
USB drivers.

Also make sure the legacy omap1-keypad.c driver builds
if selected for 2420 based systems.

ddba6c7f7e OMAP1: pass LCD config with omapfb_set_lcd_config()
LCD config for old omapfb driver is passed with OMAP_TAG_LCD from board
files or from the bootloader. In an effort to remove OMAP_TAG_LCD, this
patch adds omapfb_set_lcd_config() function that the board files can
call to set the LCD config.

This has the drawback that configuration can no longer come from the
bootloader. Of the boards supported by the kernel, this should only
affect N770 which depends on the data from the bootloader. This patch
adds an LCD config for N770 to its board files, but that is most
probably broken. Fixing this would need information about the HW setup
in N770 boards.

In an effort to clean up the old omapfb driver, this patch removes
HWA742 (the display chip used in N770) platform data. This can be done
as N770 is the only user of HWA742, and the platform data contains only
one field, te_connected, which we can just presume to be true in the
HWA742 driver.

This allows us to remove omapfb_set_ctrl_platform_data(), and the
mechanism to pass the platform data, in a later patch.

993e4fbd78 ARM: OMAP: omap_device: Expose omap_device_{alloc, delete, register}
Expose omap_device_{alloc, delete, register} so we can use them outside
of omap_device.c.

This approach allows users, which need to manipulate an archdata member
of a device before it is registered, to do so. This is also useful
for users who have their devices created very early so they can be used
at ->reserve() time to reserve CMA memory.

The immediate use case for this is to set the private iommu archdata
member, which binds a device to its associated iommu controller.
This way, generic code will be able to attach omap devices to their
iommus, without calling any omap-specific API.

With this in hand, we can further clean the existing mainline OMAP iommu
driver and its mainline users, and focus on generic IOMMU approaches
for future users (rpmsg/remoteproc and the upcoming generic DMA API).

This patch is still considered an interim solution until DT fully materializes
for omap; at that point, this functionality will be removed as DT will
take care of creating the devices and configuring them correctly.

Tested on OMAP4 with a generic rpmsg/remoteproc that doesn't use any
omap-specific IOMMU API anymore.

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.

34ed5a33b1 remoteproc/omap: add a remoteproc driver for OMAP4
Add a remoteproc driver for OMAP4, so we can boot the dual-M3 and
and DSP subsystems.

Use the omap_device_* API to control the hardware state, and utilize
the OMAP mailbox to interrupt the remote processor when a new message
is pending (the mailbox payload is used to tell it which virtqueue was
the message placed in).

Conversely, when an inbound mailbox message arrives, tell the remoteproc
core which virtqueue is triggered.

Later we will also use the mailbox payload to signal omap-specific
events like remote crashes (which will be used to trigger remoteproc
recovery) and power management transitions. At that point we will also
extend the remoteproc core to support this.

Based on (but now quite far from) work done by Fernando Guzman Lugo
<fernando.lugo@ti.com> and Hari Kanigeri <h-kanigeri2@ti.com>.

With the latest Sourcery G++ Lite 2011.03-41 and latest linaro
tool-chains OMAP2 only build breaks with below error.

OMAP2 devices doesn't have the security support but the security support
was getting built because of OMAP2PLUS. Don't build security code for
OMAP2 devices.

While at it, fix the secure-common line in the Makefile to use tabs
instead of spaces.

d0d665a896 gpio/omap: remove bank->method & METHOD_* macros
The only bank->type (method) used in the OMAP GPIO driver is MPUIO type as they
need to be handled separately. Identify the same using a flag and remove all
METHOD_* macros.

mpuio_init() function is defined under #ifdefs. It is required only in case
of MPUIO bank type and only when PM operations are supported by it.
This is applicable only in case of OMAP16xx SoC's MPUIO GPIO bank type.
For all the other cases it is a dummy function. Hence clean up the same
and remove all the OMAP SoC specific #ifdefs.

5e571f38f6 gpio/omap: cleanup set_gpio_triggering function
Getting rid of ifdefs within the function by adding register offset intctrl
and associating OMAPXXXX_GPIO_INT_CONTROL in respective SoC specific files.
Also, use wkup_status register consistently instead of referring to wakeup
clear and wakeup set register offsets. Get rid of cpu_is_xxxx checks in
set_gpio_trigger() using irqctrl.
