88e66102b7 Several more OMAP patches targeted for v3.19. They include:
- OMAP4/5: DSS hwmod cleanup patches from Tomi Valkeinen.
 - DRA7xx: hwmod data support for UARTs 7 through 10.
 - AM43xx: hwmod data support for the onboard ADC.
 
 Basic build, boot, and PM test reports are here:
 
 http://www.pwsan.com/omap/testlogs/omap-b-for-v3.19/20141121110550/
 
 Note that I cannot test the DRA7xx or AM43xx patches, since I do not have
 these boards.

1b65729a18 [media] mach-omap2: remove deprecated VIDEO_OMAP2 support
The omap2 camera driver has been deprecated for a year and is now
going to be removed. It is unmaintained and it uses an internal API
that has long since been superseded by a much better API. Worse, that
internal API has been abused by out-of-kernel trees (i.MX6).

In addition, Sakari stated that these drivers have never been in a
usable state in the mainline kernel due to missing platform data.

This patch adds hwmod support for ADC on AM43xx. Since clockdomain
and offsets of adc_tsc are different from AM33xx, ADC data has been
directly added to AM43xx hwmod file.

e639cd5bfc ARM: OMAP2+: Prepare to move GPMC to drivers by platform data header
We still need to support platform data for omap3 until it's booting
in device tree only mode. So let's add platform_data/omap-gpmc.h for
that, and a minimal linux/omap-gpmc.h for the save and restore used
by the PM code.

Let's also keep a minimal mach-omap2/gpmc.h still around to avoid
churn on the board-*.c files. Once omap3 boots in device tree only
mode, we can drop mach-omap2/gpmc.h and we can make the data
structures in platform_data/omap-gpmc.h private to the GPMC driver.

Note that we can now also remove gpmc-nand.h and gpmc-onenand.h.

594b5d51c6 Drop few unused omap board files. The support for ti81xx is known to
be incomplete and broken, and the 3430sdp is only used in few automated
 boot test systems AFAIK and those have been booting in device tree only
 mode for quite some time now.
 
 Note that this branch has a dependency to the related device tree
 changes and GPMC changes sent in a separate pull request.

RFBI iclk was set to point to hacky "dss_fck", which will be removed.
Instead use "l3_div_ck", which is the proper clock for this. "l3_div_ck"
is the parent of "dss_fck", so the clock rate is the same as previously.

9889278181 Some OMAP clock/hwmod patches for v3.19.
Most of the patches are clock-related.  The DPLL implementation is
 changed to better align to the common clock framework.
 There is also a patch that removes a few lines from the hwmod code -
 this patch should have no functional effect.
 
 Basic build, boot, and PM test logs for these patches can be found here:

79005fbd3e ARM: OMAP2+: hwmod: drop unnecessary list initialization
ml->node and sl->node are currently initialized
by means of INIT_LIST_HEAD(). That initialiation
is followed by a list_add() call.

Looking at what both these functions do we will have:

	ml->node.next = &ml->node;
	ml->node.prev = &ml->node;
	oi->master->master_ports.next.prev = &ml->node;
	ml->node.next = &oi->master->master_ports.next;
	ml->node.prev = &oi->master->master_ports;
	oi->master->master_ports.next = &ml->node;

from this, it's clear that both INIT_LIST_HEAD() calls
are unnecessary and can be safely removed.

2e1a7b014f ARM: OMAP3+: DPLL: use determine_rate() and set_rate_and_parent()
Currently, DPLLs are hiding the gory details of switching parent
within set_rate, which confuses the common clock code and is wrong.
Fixed by applying the new determine_rate() and set_rate_and_parent()
functionality to any clock-ops previously using the broken approach.
This patch also removes the broken legacy code.

83501ff0a5 ARM: OMAP4: clock: add support for determine_rate for omap4 regm4xen DPLL
Similarly to OMAP3 noncore DPLL, the implementation of this DPLL clock
type is wrong. This patch adds basic functionality for determine_rate
for this clock type which will be taken into use in the patches following
later.

d539efa37f ARM: OMAP3: clock: add new rate changing logic support for noncore DPLLs
Currently, DPLL code hides the re-parenting within its internals, which
is wrong. This needs to be exposed to the common clock code via
determine_rate and set_rate_and_parent APIs. This patch adds support
for these, which will be taken into use in the following patches.

f0d2f68a63 ARM: OMAP3: clock: use clk_features flags for omap3 DPLL4 checks
DPLL4 can't be reprogrammed on OMAP3430 ES1.0 due to hardware limitation.
Currently, the code does runtime omap_rev() check to see the chip it is
being executed on, instead, change this to use clk_features flags.
This avoids need for runtime omap_rev() checks.

b82b6cca48 cpuidle: Invert CPUIDLE_FLAG_TIME_VALID logic
The only place where the time is invalid is when the ACPI_CSTATE_FFH entry
method is not set. Otherwise for all the drivers, the time can be correctly
measured.

Instead of duplicating the CPUIDLE_FLAG_TIME_VALID flag in all the drivers
for all the states, just invert the logic by replacing it by the flag
CPUIDLE_FLAG_TIME_INVALID, hence we can set this flag only for the acpi idle
driver, remove the former flag from all the drivers and invert the logic with
this flag in the different governor.

a30d81b98a ARM: OMAP4+: PM: Program CPU logic power state
CPU logic power state is never programmed in either the initialization
or the suspend/resume logic, instead, we depend on mpuss to program this
properly. However, this leaves CPU logic power state indeterminate and
most probably in reset configuration (If bootloader or other similar
software have'nt monkeyed with the register). This can make powerstate=
RET be either programmed for CSWR (logic=ret) or OSWR(logic = OFF) and
in OSWR, there can be context loss when the code does not expect it.

To prevent all these confusions, just support clearly ON, INA, CSWR,
OFF which is the intent of the existing code by explicitly programming
logic state.

NOTE: since this is a hot path (using in cpuidle), the exit path just
programs powerstate (logic state is immaterial when powerstate is ON).

Without doing this, we end up with lockups when CPUs enter OSWR and
multiple blocks loose context, when we expect them to hit CSWR.

Commit 705814b5ea ("ARM: OMAP4+: PM: Consolidate OMAP4 PM code to
re-use it for OMAP5")

Moved logic generic for OMAP5+ as part of the init routine by
introducing omap4_pm_init. However, the patch left the powerdomain
initial setup, an unused omap4430 es1.0 check and a spurious log
"Power Management for TI OMAP4." in the original code.

Remove the duplicate code which is already present in omap4_pm_init from
omap4_init_static_deps.

As part of this change, also move the u-boot version print out of the
static dependency function to the omap4_pm_init function.

the following errors:

omap_l3_smx omap_l3_smx.0: couldn't request debug irq
omap_l3_smx: probe of omap_l3_smx.0 failed with error -22

This is because we don't have handling in the driver for the
compatible property and instead assume platform data being
passed.

Note that this binding is already documented, and implemented
for the related omap_l3_noc driver for omap4 and later. Looks
like the binding somehow never got never implemented for this
omap_l3_smx driver though.

Let's also remove __exit_p to allow binding and unbinding
of the driver while at it.

There are cases where we have multiple device instances
connected to a single GPMC chip select. For example, there
are four UARTs on the Zoom debug boards that all share a
single chip select and a GPIO interrupt.

We do have support for this already in theory, but it's broken
because we're bailing out if the chip select is already taken.

To be able to provide checks on the chip select usage, let's
add new struct gpmc_cs_data so we can start using already
registered device names for checks.

Later on we probably want to start using struct gpmc_cs_data
as a wrapper for all the GPMC chipselect related data.

2084becbe1 ARM: SoC fixes for 3.8-rc3
A surprisingly small batch of fixes for -rc3. Suspiciously small, I'd say.
 
 Anyway, most of this are a few defconfig updates. Some for omap to deal
 with kernel binary size (moving ipv6 to module, etc). A larger one for
 socfpga that refreshes with some churn, but also turns on a few options
 that makes the newly-added board in my bootfarm usable for testing.
 
 OMAP3 will also now warn when booted with legacy (non-DT) boot protocols,
 hopefully encouraging those who still care about some of those platforms
 to submit DT support and report bugs where needed. Nothing stops working
 though, this is just to warn for future deprecation.
 
 Beyond this, very few actual bugfixes. A PXA fix for DEBUG_LL boot hangs,
 a missing terminting entry in a dt_match array on RealView a MTD fix on
 OMAP with NAND.

7d2911c438 net: smc91x: Fix gpios for device tree based booting
With legacy booting, the platform init code was taking care of
the configuring of GPIOs. With device tree based booting, things
may or may not work depending what bootloader has configured or
if the legacy platform code gets called.

Let's add support for the pwrdn and reset GPIOs to the smc91x
driver to fix the issues of smc91x not working properly when
booted in device tree mode.

And let's change n900 to use these settings as some versions
of the bootloader do not configure things properly causing
