and use the proper wrappers.

NOTE!

This merge commit was created to fix compilation error. The block
tree was merged upstream and removed the 'elv_queue_empty()'
function which the new 'mtdswap' driver is using. So a simple
merge of the mtd tree with upstream does not compile. And the
mtd tree has already be published, so re-basing it is not an option.

To fix this unfortunate situation, I had to merge upstream into the
mtd-2.6.git tree without committing, put the fixup patch on top of
this, and then commit this. The result is that we do not have commits
which do not compile.

In other words, this merge commit "merges" 3 things: the MTD tree, the
upstream tree, and the fixup patch.

Add new/changed base address definitions and resources for

77aded2f52 ARM: OMAP2+: Fix warnings for GPMC interrupt
Commit db97eb7dfe
(omap: gpmc: enable irq mode in gpmc) enabled interrupts for
GPMC (General Purpose Memory Controller). However, looks like
this patch only works on omap3. Fix the issues to avoid warnings
on omap4 during the boot.

GPMC: number of chip select is 8, CS0 to CS7. One less IRQ
allocated throws below warning at boot:

[    0.429290] Trying to install type control for IRQ409
[    0.429290] Trying to set irq flags for IRQ409

Resolve following warning messages in boot when irq chip is not set:

[    0.429229] Trying to install interrupt handler for IRQ402
[    0.429229] Trying to install interrupt handler for IRQ403
[    0.429229] Trying to install interrupt handler for IRQ404
[    0.429260] Trying to install interrupt handler for IRQ405

[    0.429260] Trying to install interrupt handler for IRQ407
[    0.429290] Trying to install interrupt handler for IRQ408

Resolve following warning in OMAP4:
[    0.429290] gpmc: irq-20 could not claim: err -22

d038aee24d omap: iovmm: don't check 'da' to set IOVMF_DA_FIXED flag
Currently IOVMM driver sets IOVMF_DA_FIXED/IOVMF_DA_ANON flags according
to input 'da' address when mapping memory:
da == 0: IOVMF_DA_ANON
da != 0: IOVMF_DA_FIXED

It prevents IOMMU to map first page with fixed 'da'. To avoid such
issue, IOVMM will not automatically set IOVMF_DA_FIXED. It should now
come from the user throught 'flags' parameter when mapping memory.
As IOVMF_DA_ANON and IOVMF_DA_FIXED are mutually exclusive, IOVMF_DA_ANON
can be removed. The driver will now check internally if IOVMF_DA_FIXED
is set or not.

5ee3c1445d OMAP: DSS2: Functions to request/release DSI VCs
Introduce functions which request and release VC's. This will be used in panel
drivers in their probes.

omap_dsi_request_vc() takes in the pointer to the omap_dss_device, the VC_ID
parameter which goes into the header of the DSI packets, and returns a Virtual
channel number (or virtual channel register set) which it can use.

omap_dsi_set_vc_id() takes the omap_dss_device pointer, the Virtual Channel
number and the VC_ID that needs to be set for the specifed Virtual Channel.

omap_dsi_release_vc() takes the omap_dss_device pointer and the Virtual Channel
number that needs to be made free.

Initialisation of VC parameters is done in dsi_init().

DSI PLL output clock names have been made more generic. The clock name
describes what the source of the clock and what clock is used for. Some of
DSI PLL parameters like dividers and DSI PLL source have also been made more
generic.

dsi1_pll_fclk and dsi2_pll_fclk have been changed as dsi_pll_hsdiv_dispc_clk
and dsi_pll_hsdiv_dsi_clk respectively. Also, the hsdividers are now named
regm_dispc and regm_dsi instead of regm3 and regm4.

Functions and macros named on the basis of these clock names have also been

9599217a06 OMAP2+: hwmod: add API to handle autoidle mode
Create a new API that forms a wrapper to _set_module_autoidle()
to modify the AUTOIDLE bit.

This API is intended to be used by drivers that requires direct
manipulation of the AUTOIDLE bits in SYSCONFIG register.
McBSP driver requires autoidle bit to be enabled/disabled while
using sidetone feature.

43b0164335 OMAP2+: hwmod: allow board files to prevent devices from being reset upon init
Some boards can't tolerate IP blocks being reset when they are initialized.
Michael Büsch cites a case with the Nokia N810:

    http://www.spinics.net/lists/linux-omap/msg47277.html

To allow such boards to continue working normally, allow board file
maintainers to mark IP blocks to prevent them from being reset upon
init.  This is done via a hwmod function, omap_hwmod_no_setup_reset().

cc1226e763 OMAP2+: hwmod: use status bit info for reset line
On OMAP2 and OMAP3 the reset ctrl shift doesn't match the
status bit, as it does on OMAP4, when handling the reset lines.

This patch adds a new member in the reset info structure, so now it
can be added as part of hwmod data, and checked accordingly for
OMAP2 or 3; otherwise, there could be cases when the shift masks
doesn't match both of the registers, and a successful reset might
throw an error message or vice versa.

Now that omap_hwmod + omap_device is used for OMAP UART device and
driver code, we no longer need the UART physical addresses in
omap_globals.

Note that the #defines for the base addresses are still left in
<plat/serial.h> since they are used by DEBUG_LL and uncompress code.

Remove the DPLL rate tolerance code that is called during rate
rounding.  As far as I know, this code is never used, since it's been
more important for callers of the DPLL round_rate()/set_rate()
functions to obtain an exact rate than it is to save a relatively
small amount of power.

da0653fe01 OMAP2+: omap_device/clock: Do not expect an entry in clkdev for opt_clks
The _add_optional_clock_alias function expects an entry
already existing in the clkdev table in the form of
<dev-id=NULL, con-id=role> which might not be the case
always.

Instead, just check if an entry already exists in clkdev
in the <dev-id=dev_name, con-id=role> form, else go ahead
and add one.

Remove any assumption of an entry already existing in clkdev
table in any form.

Since this means, adding a new entry in clkdev if it does
not already exist, and not really adding an 'alias',
also rename the function name
(s/_add_optional_clock_alias/_add_optional_clock_clkdev)
to reflect this.

4621d5f8cb OMAP: adapt hsmmc to hwmod framework
OMAP2420 platform consists of mmc block as in omap1 and not the
hsmmc block as present in omap2430, omap3, omap4 platforms.
Removing all base address macro defines except keeping one for OMAP2420 and
adapting only hsmmc device registration and driver to hwmod framework.

Changes involves:
1) Remove controller reset in devices.c which is taken care of
   by hwmod framework.
2) Using omap-device layer to register device and utilizing data from
   hwmod data file for base address, dma channel number, Irq_number,
   device attribute.
3) Update the driver to use dev_attr to find whether controller
   supports dual volt cards

e08016d0f4 omap: mmc: split out init for 2420
The MMC controller on the OMAP2420 is different from those
on the OMAP2430, OMAP3 and OMAP4 families - all of the latter
are identical. The one on the OMAP2420 is closer to that
on OMAP1 chips.

Currently, the n8x0 is the only OMAP2420 platform supported
in mainline which registers the MMC controller. Upcoming
changes to register the controllers using hwmod data are
potentially invasive. To reduce the risk, separate out the
2420 controller registration from the common init function
and update its only user. Also seperating out mux settings
for OMAP2420.
