Laurent Pinchart c56b2ddd5f omap: iommu: Return IRQ_HANDLED in fault handler when no fault occured
Commit d594f1f31a (omap: IOMMU: add
support to callback during fault handling) broke interrupt line sharing
between the OMAP3 ISP and its IOMMU. Because of this, every interrupt
generated by the OMAP3 ISP is handled by the IOMMU driver instead of
being passed to the OMAP3 ISP driver.

Nicolas Pitre 8ea0de4b88 ARM: zImage: remove the static qualifier from global data variables
To be able to relocate the .bss section at run time independently from
the rest of the code, we must make sure that no GOTOFF relocations are
used with .bss symbols.  This usually means that no global variables can
be marked static unless they're also const.

Let's remove the static qualifier from current offenders, or turn them
into const variables when possible.  Next commit will ensure the build
fails if one of those is reintroduced due to otherwise enforced coding
standards for the kernel.

Kevin Hilman 638080c37a OMAP2+ / PM: move runtime PM implementation to use device power domains
In commit 7538e3db6e (PM: add support
for device power domains) a better way for handling platform-specific
power hooks was introduced.

Rather than using the platform_bus dev_pm_ops overrides
(platform_bus_set_pm_ops()), this patch moves the OMAP runtime PM
implementation over to using device power domains.

Since OMAP is the only user of platform_bus_set_pm_ops(), that
interface can be removed (and will be in a forthcoming patch.)

[rjw: Rebased on top of a previous change modifying the handling of
 power domains by the PM core so that power domain callbacks take
 precendence over subsystem-level PM callbacks.]

Santosh Shilimkar 43b3e18982 ARM: 6860/1: OMAP4: Move the privately used SMP boot functions to OMAP specific header.
Header files in arch/arm/*/include/mach included from
arch/arm/include/asm/*.h are there to provide necessary definitions for
either the rest of the kernel or the ARM specific parts.  They shouldn't
be polluted with *any* platform private stuff which is not absolutely
necessary to satisfy the rest of the kernel.

Hence move the OMAP specific SMP boot functions to different header
instead of keeping them in 'plat/smp.h' which gets included indirectly
by linux/smp.h

The patch is outcome of the discussion in below thread:

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.

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 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 IRQ403

David Cohen 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.

Introduce functions which request and release VC's. This will be used in panel

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.

The _add_optional_clock_alias function expects an entry
already existing in the clkdev table in the form of

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.

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

Paul Walmsley a2debdbd1a OMAP2+: hwmod: add ability to setup individual hwmods
Add omap_hwmod_setup_one(), which is intended for use early in boot to
selectively setup the hwmods needed for system clocksources and
clockevents, and any other hwmod that is needed in early boot.
omap_hwmod_setup_all() can then be called later in the boot process.
The point is to minimize the amount of code that needs to be run
early.

Rajendra Nayak 97f678989a OMAP4: DPLL: Add dpll api to control GATE_CTRL
On OMAP4, the dpll post divider outputs (MX outputs)
along with clockout_x2 output provide a way to allow/deny
hardware level autogating.
Allowing autoidle would mean that the hw would autogate
this clock when there is no dependency for it.
Denying idle would mean that this clock output will be
forced to stay enabled.

Add dpll api's to read/allow/deny idle control
for these dpll mx postdividers.

NOTE: The gatectrl bit set to 0 allows gatectrl,
and the bit set to 1 denies gatectrl.

Paul Walmsley b80b956dc5 OMAP2+: clock: autoidle as many clocks as possible if CONFIG_OMAP_RESET_CLOCKS
Attempt to enable autoidle for as many clocks as possible in the
OMAP2+-common CONFIG_OMAP_RESET_CLOCKS code.  Currently, this only
enables DPLL autoidle for OMAP3/4 DPLLs; but future patches will
enable autoidle for other clocks and the OMAP2 DPLL/APLLs.

In the long run, we should probably get rid of
CONFIG_OMAP_RESET_CLOCKS, and unconditionally run the code that it
selects.  Otherwise, the state of the clock tree won't match the
hardware state - this could result in clocks being enabled or disabled
unpredictably.

Based on a patch by Rajendra Nayak <rnayak@ti.com> that did this in
the pm34xx.c/pm44xx.c code.

Rajendra Nayak 58e846fe78 OMAP: clock: Add allow_idle/deny_idle support in clkops
On OMAP various clock nodes (dpll's, mx post dividers, interface clocks)
support hardware level autogating which can be controlled from
software.
Support such functionality by adding two new function pointer
allow_idle and deny_idle in the clkops structure.

These function pointers can be populated for any clock
node which supports hardware level autogating.

Also add 2 new functions (omap_clk_enable_autoidle_all and
omap_clk_disable_autoidle_all) which can be called from
architecture specific PM core code, if hardware level
autogating (for all supported clock nodes) is to be
enabled or disabled.

Hwmod needs database of all IPs in a system. This patch generates the hwmod
database for Display Sub System applicable for OMAP3430 and
OMAP36xx.  DSS is also considered as an IP as DISPC, RFBI and named as dss_core.
For all the IP modules in DSS, same clock is needed for enabling. Hwmod sees
DSS IPs as independent IPs, so same clock has to be repeated for .main_clk in
each IP.

This patch defines separate hwmod databases for OMAP3430ES1 and (OMAP3430ES2 and
OMAP36xx) as OMAP3430ES1 does not have IDLEST bit to poll on for dss IP, and also
the firewall regions are different between 3430es1 and later.

Allow OMAP4 ES2.1 and ES2.2 revisions to be recognized in the

Mainly, ES2.1 has fixes that allow LPDDR to be used at 100% OPP (400MHz).
ES2.2 additionally has a couple of power management fixes (to reduce
leakage), an I2C1 SDA line state fix, and a floating point write
corruption fix (cortex erratum).

Even though the current mainline support doesn't need to distinguish
between ES2.X versions, it's still useful to know the correct silicon
rev when issues are reported. Moreover, these id checks can be used by
power management code that selects suitable OPPs considering the
memory speed limitation on ES2.0.

Santosh Shilimkar b9b35ade88 omap4: Remove 'FIXME: omap44xx_sram_init not implemented'
The omap44xx_sram_init() implements functionality to push some
code on SRAM whenever the code can't be executed from external
memory. The low power and DVFS code can be executed from
external DDR itself thanks to OMAP4  memory controller hardware
support. So on OMAP4, sram_push kind of functionality isn't needed.

Hence remove the FIXME warning added for implementing sram push
feature on OMAP4.

Charulatha V 1a5d81905a OMAP: devices: Modify McSPI device to adapt to hwmod framework
Cleans up all base address definitions for omap_mcspi
and adapts the device registration and driver to hwmod framework.
Changes involves:
1) Removing all base address macro defines.
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(number of chipselect).
3) Appending base address with pdata reg_offset for omap4 boards.
   For omap4 all regs used in driver deviate with reg_offset_macros
   defined with an value of 0x100. So pass this offset through pdata
   and append the same to base address retrieved from hwmod data file
   and we are not mapping *_HL_* regs which are not used in driver.

Hemant Pedanekar 4bd7be22f4 TI816X: Update common omap platform files
This patch updates the common platform files with TI816X support.

The approach taken in this patch is to add TI816X as part of OMAP3 variant where
the cpu class is considered as OMAP34XX and the type is TI816X. This means, both
cpu_is_omap34xx() and cpu_is_ti816x() checks return success on TI816X.

A kernel config option CONFIG_SOC_OMAPTI816X is added under OMAP3 to include
support for TI816X build.

The new fncpy API is better suited* for copying some
code to SRAM at runtime. This patch changes the ad-hoc
code to the more generic fncpy API.

*: 1. fncpy ensures that the thumb mode bit is propagated,
   2. fncpy provides the security of type safety between the
     original function and the sram function pointer.

Tested OK on OMAP3 in low power modes (RET/OFF)
using omap2plus_defconfig with !CONFIG_THUMB2_KERNEL.

Sumit Semwal 18faa1b68a OMAP: DSS2: Introduce omap_channel as an omap_dss_device parameter, add new overlay manager.
A panel connects to one of the overlay managers of DSS through some interface block.
On OMAP4, specifying the type of the display is not sufficient to conclude which manager
the panel should be connected to.
Hence, a new member 'channel' is introduced in omap_dss_device structure to determine
which manager the panel uses. The dss_recheck_connections() called in dss_driver_probe()
uses this channel parameter to set the correct manager to the corresponding omap_dss_device.

The channel parameter is used only once to ensure the correct managers are set for each
panel. The parameter dssdev->manager->id will take care of ensuring that the panel and
then the interface driver configures the correct DISPC channel.

Also, add a new Overlay Manager in manager.c, make other changes needed for LCD2 channel.

Sumit Semwal 2a205f34b8 OMAP: DSS2: LCD2 Channel Changes for DISPC
DISPC functions are modified in order to work when the manager is LCD2.
This includes:
Adding new IRQs specific to LCD2 and their handling.
Provide dumps of the new manager's registers.
Provide dumps of the new manager's clocks.
Checks for channel for registers DISPC_CONTROL2 and DISPC_CONFIG2
which can't be parametrized.
