Samsung mach/soc changes for v5.2
1. Cleanup in mach code.
2. Add necessary fixes for Suspend to RAM on Exynos5422 boards (tested
with Odroid XU3/XU4/HC1 family). Finally this brings a working S2R
on these Odroid boards (still other drivers might have some issues
but mach code seems to be finished).
3. Require MCPM for Exynos542x boards because otherwise not all of cores
will come online.
4. GPIO regulator cleanup on S3C6410 Craig.

Driver changes for ti-sysc for v5.2 merge window
This series of changes for ti-sysc interconnect target module driver
gets us to the point where we can actually drop legacy platform data
for many devices in favor of device tree data.
To do this, we improve ti-sysc driver not to rely on platform data
callbacks to manage module clocks, and handle more quirks needed for
some devices. Also few minor fixes are needed, but were considered
not needed to be sent separately as they only show up with this series.
Then we drop several thousands of lines of legacy platform data for
omap4, omap5, dra7, am335x and am437x. We drop platform data for mmc,
i2c, gpio and uart devices to start with as those are typically
easily tested on all devices. In case of unexpected issues, we can just
add back the legacy platform data for a single device type if needed.
Finally we add initial support for enabling and disabling some devices
without legacy platform data callbacks. I was planning on sending the
dropping of legacy platform data as a separate series, but already
applied Roger's patch on top and pushed it out.
Note that this series depends on related SoC and is based on those.

SoC changes for omap variants for v5.2 merge window
This series of changes mostly consists of ti-sysc interconnect driver

In preparation of dropping interconnect target module platform data in
favor of devicetree based data, we must pass swsup idle quirks to the
platform data functions.
For now, let's only tag the UART modules with the SWSUP_SIDLE_ACT quirk.
The other modules will get tagged with swsup quirks as we drop the
platform data and test the changes.

We already have the clockactivity quirk set for some modules like i2c,

yet. Let's start doing that in preparation of dropping interconnect target
module platform data in favor of device tree based data.

We cannot access mcpdm registers at all unless there is an optional pdmclk
configured. As this is currently only needed for mcpdm, let's check for
mcpdm in sysc_get_clocks(). If it turns out to be needed for other modules
too, we can add more flags to the quirks table for this.
Signed-off-by: Tony Lindgren <tony@atomide.com>
At least mcpdm needs an optional external clock enabled to function and
this clock typically comes from the PMIC. We can detect mcpdm based on
the interconnect target module address and set a quirk flag early.
To do this, let's initialize the clocks a bit later and add a new
function for sysc_init_early_quirks(). Note that we cannot yet enable
the early quirks for mcpdm until the optional external clocks are
handled in the in the following patch.
Signed-off-by: Tony Lindgren <tony@atomide.com>
We can do the rsstctrl a bit later, but need to deassert rstctrl reset
before the clocks are enabled if asserted. Let's only init restctrl
in sysc_init_resets() and do the reset later on just before we enable
the device clocks.

We are currently not managing interconnect target module clocks in the
for legacy platform data based case. This causes a problem for using the
platform data based functions when dropping the platform data for the
interconnect target module configuration.
To avoid a situation where we need to populate the main and optional
clocks also for the platform data based functions, let's just manage the
clocks directly in ti-sysc driver. This means that until the interconnect
target module confugration platform data is dropped our use count for
clk_enable() will be 2 instead of 1.

The platform data based init functions typically reset the interconnect
target module configure the registers. As we may need the interconnect
target module specific quirks configured based on the revision register,
we want to move the platform data based init to happen later.
Let's allocate mdata as needed so it's available for sysc_legacy_init()
that we call with module clocks enabled from sysc_init_module().
Signed-off-by: Tony Lindgren <tony@atomide.com>
The first thing we want to do is just read the module revision register to
be able to configure the module specific quirks and configure the module
registers.
As the interconnect target module may not yet be properly configured and
may need a reset first, we don't want to use pm_runtime_get() at this
point.
To read the revision register, let's just enable the all the clocks for
the interconnect target module during init even if the optional clocks
are not needed. That way we can read the revision register to configure
the quirks needed for PM runtime.

At least McPDM module depends on an external optional clock to be
usable. To make handling of the McPDM clock easier in the following

while at it.
