omap3xxx_prm_enable_io_wakeup() is marked __init, but its caller is not, so
we get a warning with clang-8:
WARNING: vmlinux.o(.text+0x343c8): Section mismatch in reference from the function omap3xxx_prm_late_init() to the function .init.text:omap3xxx_prm_enable_io_wakeup()
The function omap3xxx_prm_late_init() references
the function __init omap3xxx_prm_enable_io_wakeup().
This is often because omap3xxx_prm_late_init lacks a __init
annotation or the annotation of omap3xxx_prm_enable_io_wakeup is wrong.
When building with gcc, omap3xxx_prm_enable_io_wakeup() is always
inlined, so we never noticed in the past.

call dev_info() if am437x is suspending to RTC-only mode. We want to
see this in case of issues as it depends on the board wiring for things

ti-sysc interconnect target module driver changes for v5.3
This series of changes improves probing devices with ti-sysc to the
point where we can now probe most devices without the custom dts
property "ti,hwmods" and no legacy platform data :)
We add support for platform data callbacks for idling and unidling the
clockdomain the module belongs to. The rest of the series mostly adds
handling for the various quirks needed by old legacy modules such as
i2c and watchdog. Some quirk handling is still missing for few modules,
but those will be added as they get tested.
The related platform data and dts changes will be sent separately.

We need to let ti-sysc driver manage clockdomain autoidle for the
duration of of reset, enable and idle. And we need to do it before we
enable the clock and after we disable it. Currently we are still
relying on platform callbacks indirectly managing clockdomain autoidle.
But I noticed that for device tree only probed drivers it now happens
only after we enabling the clocks and before we disable the clocks,
while it should be the other way around. So far I have not noticed
any issues with this though.
Let's add new ti_sysc_clkdm_deny_idle() and ti_sysc_clkdm_allow_idle()
functions for ti-sysc driver to use to manage clockdomains directly via
platform data callbacks. Note that we can implement the clockdomain
functions in pdata-quirks.c as for probing devices without "ti,hwmods"
custom property we don't need to use the other platform data callbacks.
Let's do this in one patch as there's is still an unlikely chance we
may need to apply this as a fix for v5.2 for dropping legacy platform
data for some devices. We also do have the option of adding back the
platform data if needed in case of trouble.

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.

With ti-sysc interconnect target module, we can allocate struct omap_hwmod

To allocate struct omap_hwmod dynamically, we need to add a mutex for

Note that we are not initialized oh->_clk or the optional clocks and their
