commit 0c0ef9ea6f3f0d5979dc7b094b0a184c1a94716b upstream.
Commit 0ed266d7ae5e ("clk: ti: omap3: cleanup unnecessary clock aliases")
removed old omap3 clock framework aliases but caused omap3-rom-rng to
stop working with clock not found error.
Based on discussions on the mailing list it was requested by Tero Kristo
that it would be best to fix this issue by probing omap3-rom-rng using
device tree to provide a proper clk property. The other option would be
to add back the missing clock alias, but that does not help moving things
forward with removing old legacy platform_data.
Let's also add a proper device tree binding and keep it together with
the fix.

commit 2398c41d64321e62af54424fd399964f3d48cdc2 upstream.
With a wl1251 child node of mmc3 in the device tree decoded
in omap_hsmmc.c to handle special wl1251 initialization, we do
no longer need to instantiate the mmc3 through pdata quirks.
We also can remove the wlan regulator and reset/interrupt definitions
and do them through device tree.

commit 4e8fad98171babe019db51c15055ec74697e9525 upstream.
This partly reverts the commit efdfeb079cc3 ("regulator: fixed: Convert to
use GPIO descriptor only").
We must remove this from mainline first, so that the following patch
to remove the openpandora quirks for mmc3 and wl1251 cleanly applies
to stable v4.9, v4.14, v4.19 where the above mentioned patch is not yet
present.
Since the code affected is removed (no pandora gpios in pdata-quirks
and more), there will be no matching revert-of-the-revert.

This pushes the handling of inversion semantics and open drain
settings to the GPIO descriptor and gpiolib. All affected board
files are also augmented.
This is especially nice since we don't have to have any
confusing flags passed around to the left and right littering
the fixed and GPIO regulator drivers and the regulator core.
It is all just very straight-forward: the core asks the GPIO
line to be asserted or deasserted and gpiolib deals with the
rest depending on how the platform is configured: if the line
is active low, it deals with that, if the line is open drain,
it deals with that too.

The OMAP HSMMC driver has some elaborate and hairy handling for
passing GPIO card detect and write protect lines from a boardfile
into the driver: the machine defines a struct omap2_hsmmc_info
that is copied into struct omap_hsmmc_platform_data by
omap_hsmmc_pdata_init() in arch/arm/mach-omap2/hsmmc.c.
However the .gpio_cd and .gpio_wp fields are not copied from
omap2_hsmmc_info to omap_hsmmc_platform_data by
omap_hsmmc_pdata_init() so they remain unused. The only platform
defining omap2_hsmmc_info also define both to -1, unused.
It turn out there are no boardfiles passing any valid GPIO
lines into the OMAP HSMMC driver at all. And since we are not
going to add any more OMAP2 boardfiles, we can delete this
card detect and write protect handling altogether.
This seems to also fix a bug: the card detect callback
mmc_gpio_get_cd() in the slot GPIO core needs to be called
by drivers utilizing slot GPIO. It appears the the boardfile
quirks were not doing this right, so this would only get
called for boardfiles, i.e. since no boardfile was using it,
never.
Just assign mmc_gpio_get_cd() unconditionally to omap_hsmmc_ops
.get_cd() so card detects from the device tree works.
AFAICT card detect with GPIO lines assigned from
mmc_of_parse() are not working at the moment, but that is
no regression since it probably never worked.

As we augmented the regulator core to accept a GPIO descriptor instead
of a GPIO number, we can augment the fixed GPIO regulator to look up
and pass that descriptor directly from device tree or board GPIO
descriptor look up tables.
Some boards just auto-enumerate their fixed regulator platform devices
and I have assumed they get names like "fixed-regulator.0" but it's
pretty hard to guess this. I need some testing from board maintainers to
be sure. Other boards are straight forward, using just plain
"fixed-regulator" (ID -1) or "fixed-regulator.1" hammering down the
device ID.
It seems the da9055 and da9211 has never got around to actually passing
any enable gpio into its platform data (not the in-tree code anyway) so we
can just decide to simply pass a descriptor instead.
The fixed GPIO-controlled regulator in mach-pxa/ezx.c was confusingly named
"*_dummy_supply_device" while it is a very real device backed by a GPIO
line. There is nothing dummy about it at all, so I renamed it with the
infix *_regulator_* as part of this patch set.

Looks like these functions don't do anything in the mainline kernel so
we can just drop it.
Note that we must now also remove ir-rx51 pdata as it relies on the dummy
platform data that does not do anything. And ir-rx51 is calling a pdata
callback that doesn't do anything without checking if it exists first.
For configuring device specific minimal latencies, the interface to use
is pm_qos_add_request(). For an example, see what was done in commit
9834ffd1ecc3 ("ASoC: omap-mcbsp: Add PM QoS support for McBSP to prevent
glitches"). I've added some comments to ir-rx51 so people using it can
add pm_qos support and test it.

Pull "Driver changes for ti-sysc for v4.17" from Tony Lindgren:
This series of changes enables the use device tree based sysconfig
data for ti-sysc driver. As we already have SmartReflex data configured,
we use that as the first driver to enable. To do that in a way where
SmartReflex is not probed twice, we need to prepare the SmartReflex
driver before flipping dts data on for it in the last patch of the
series.
To avoid regressions, we are checking the passed dts data against
existing platform data since we still have it available. Then after the
dts files are converted, we can simply drop the related platform data
at some point in the future.

Let's enable ti-sysc probing of child devices. So far we have only used
ti-sysc to probe interconnect target modules to idle them for cases where
the SoC does not have any child devices configured for the module, such
as smartreflex on dra7.
As we have smartreflex driver configured in the device tree for some SoCs,
we need to flip things on with a single patch to prevent both omap_device
and ti-sysc to probe smartreflex. So let's stop probing smartreflex with
omap_device and probe it with ti-sysc by enabling passing the auxdata.

We want to pass the device tree configuration for interconnect target
modules from ti-sysc driver to the existing platform hwmod code.
This allows us to first validate the dts data against the existing
platform data before we start dropping the platform data in favor of
device tree data.
To do this, let's add platform data callbacks for PM runtime functions
to call for the interconnect target modules if platform data is
available.
Note that as ti-sysc driver can rebind, omap_auxdata_lookup and related
functions can no longer be __init.

We are still initializing smartreflex with platform data using
omap_device_build(). We can instead pass the platform data in
with auxdata in pdata-quirks.c and make the driver use that
in later patches.
Note that we cannot enable the auxdata use yet, this is done
in the last patch of the series.

The device-tree file is written to support rev 2.0 of

McBSP2/3 module's sidetone module operates using the module's ICLK clock.
When the Sidetone is in use the interface clock of the module must not
idle. To prevent the iclk idling the driver expects to have pdata callback

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/fixes-non-critical
Merge "non urgent auxdata fix for v4.7 merge window" from Tony Lindgren:
Device tree auxdata handling fix that allows a match based on the
compatible string if no exact match based on the IO address is found.
This leaves out the need to patch auxdata for each driver when adding
new SoCs. And it also reprotedly fixes the issue of passing auxdata
to a child if the parent instantiates the child from DT as discussed
in the "[PATCH] of/platform: Allow secondary compatible match in
of_dev_lookup" mailing list thread.
As a minimal use case, let's also convert omap pinctrl auxdatato
use a generic match.
There is no need to get this in to the v4.6-rc cycle and it can wait
for v4.7 merge window. Note that these changes have now been sitting
in Linux next for about two weeks so far as I wanted to make sure no
new issues are popping up.

Let's pass the slot names in pdata like the legacy code does.
Once we have a generic DT binding for the slot names we can
switch to that.

Before we start removing omap3 legacy booting support, let's make n900
DT booting behave the same way for ir-rx51 as the legacy booting does.
For now, we need to pass pdata to the ir-rx51 driver. This means that
the n900 tree can move to using DT based booting without having to carry
all the legacy platform data with it when it gets dropped from the mainline
tree.
Note that the ir-rx51 driver is currently disabled because of the
dependency to !ARCH_MULTIPLATFORM. This will get sorted out later
with the help of drivers/pwm/pwm-omap-dmtimer.c. But first we need
to add chained IRQ support to dmtimer code to avoid introducing new
custom frameworks.
So let's just pass the necessary dmtimer functions to ir-rx51 so we
can get it working in the following patch.

Second set of omap device tree changes for v4.5 merge window. This series
updates the EDMA bindings based on the various fixes to split EDMA into
separate independent devices. It also adds support for more devices on the
CompuLab cm-t335 and LogicPD Torpedo boards, and enables the new bindings
for qspi for am437x and dra7. There are also few dra7 regulator fixes, and
change of gpoi-key,wakeup to wakeup-source.
These depend on commit ae0add740cd0 ("dmaengine: edma: DT: Change reserved
slot array from 16bit to 32bit type") already merged into mainline.

git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc
SoC changes for omaps for v4.5 merge window. The main change here is to
change the omap initcall levels a bit to initialize things later to allow
early device drivers at core_initcall level. This makes things easier
for us as most clocks can be made into regular device drivers except for
a few early clocks needed to initialize system timers. I wanted to have
these changes sit in Linux next for a few weeks before sending out a pull
request, and so far now issues have showed up.
The other changes in this series are timer changes for making use of the
new PWM driver, and timer changes to support more high security SoCs.
Also few minor improvments for module autoidle settings for ti81xx spinbox
and dra7 debug on uart4 in hwmod code. The rest is pretty much just removal
of platform data for SoCs that are all device tree only nowadays.

Some omaps are producing imprecise external aborts because we are
wrongly trying to init SRAM for device tree based booting. Only
omap3 is still using the legacy SRAM code, so we need to make it
omap3 specific. Otherwise we can get errors like this on at least
dm814x:
Unhandled fault: imprecise external abort (0xc06) at 0xc08b156c
...
(omap_rev) from [<c08b12e0>] (omap_sram_init+0xf8/0x3e0)

(kernel_init) from [<c000f890>] (ret_from_fork+0x14/0x24)
Let's fix the issue by making sure omap_sdrc_init only gets called for
omap3. To do that, we need to have compatible "ti,omap3" in the dts
files. And let's also use "ti,omap3630" instead of "ti,omap36xx" like
we're supposed to.
