Merge "omap fixes against v4.6-rc2" from Tony Lindgren

Fixes for omaps against v4.6-rc2, mostly to fix suspend for beagle-x15
that broke when we added runtime based SoC revision detection earlier.

It seems suspend worked earlier as things were only partially initialized,
while now we initialize things properly for dra7.

Note that the "ARM: OMAP: Catch callers of revision information prior
to it being populated" had to be reverted as it caused bogus warnings
for other SoCs because omap initcalls bail out based on revision being
set to 0 for other SoCs. These initcalls will mostly just disappear
when we drop support for omap3 legacy booting.

Also included is a fix for dra7 sys_32k_ck clock source that is not
enabled on boot making system fall back to using emulated clock.

On all shmobile ARM SoCs, loop-based delays may complete early, which
can be after only 1/3 (Cortex A9) or 1/2 (Cortex A7 or A15) of the
minimum required time.

This is caused by calculating preset_lpj based on incorrect assumptions
about the number of clock cycles per loop:
  - All of Cortex A7, A9, and A15 run __loop_delay() at 1 loop per
    CPU clock cycle,
  - As of commit 11d4bb1b

 ("ARM: 7907/1: lib: delay-loop: Add
    align directive to fix BogoMIPS calculation"), Cortex A8 runs
    __loop_delay() at 1 loop per 2 instead of 3 CPU clock cycles.

On SoCs with Cortex A7 and/or A15 CPU cores, this went unnoticed, as
delays use the ARM arch timer if available. R-Car Gen2 doesn't work if
the arch timer is disabled. However, APE6 can be used without the arch
timer.

This patch fixes mt8173-evb failing boot issue. With commit [1],
genpd state will not sync to real power domain state. So some
resources such as clocks and regulators may stay in a wrong state.

There is no regulator double enabling issue on mainline kernel, so

Fixes for omaps against v4.6-rc1. Mostly minor fixes for the newer
SoCs with few board fixes and a fix for a long time hwmod bug:

- Fix cpsw_emac0 link type for baltos-ir5221
- Fix interrupt type for TWD
- Fix edma memcpy channel allocation for am43x
- Fix am43x-epos sycntimer32k by using the correct assigned clock
- Fix interconnect barrier for dra7
- Fix a long time hwmod bug for updating sysconfig register properly
- Fix flakey booting on dm814x where USB reset needs a delay

And there is one minor change that is not strictly a fix, but is
good to have for proper hardware detection:

- Detect dra7 silicon revision 2.0 properly

omap_rev is used to detect various SoC types, however any misuse of
the usage by invoking it earlier than it being populated will result
in invalid results. Lets flag them as early as possible to prevent
unintended side effects taking place. We get 0 if it is uninitialized
and -1 when detection is done using device tree (as the case was for
DRA7 as the case was prior to commit 06c2d368

This is w.r.t J6/J6eco: 32clk is pseudo (erratum i856) - clock source.
Errata i856 for the AM572x (DRA7xx) points out that the 32.768KHz external
crystal is not enabled at power up. Instead the CPU falls back to using
an emulation for the 32KHz clock which is SYSCLK1/610.  SYSCLK1 is usually
20MHz on boards so far (which gives an emulated frequency of 32.786KHz)

Modelling the same in device tree.

When commit 06c2d368 ("ARM: OMAP: DRA7: Make use of omap_revision
information for soc_is* calls") introduced SoC check using
omap_revision, it missed providing DRA7 as class for initializing
the omap_version variable. Without doing this, soc_is_dra7xx() will
fail and as a result, omap4_pm_init_early never initializes the dra7
erratum for CPU power state. This causes the suspend path to fail
on DRA7 devices.

DRA7 has no SAR region for automated save and restore of wakeupgen,
which does not make real since the SoC really does not do legacy OFF
mode anymore. Further wakeupgen should never loose context in CSWR
retention mode for MPU domain on DRA7 since that is the deepest state
we will enter.

So, just skip, instead of oopsing as follows while attemptint to enter
suspend on BeagleBoard-X15.

Newer Fedora and OpenSUSE didn't boot with my standard configuration.
It took me some time to figure out why, in fact I had to write a script
to try different config options systematically.

The problem is that something (systemd) in dracut depends on
CONFIG_FHANDLE, which adds open by file handle syscalls.

While it is set in defconfigs it is very easy to miss when updating
older configs because it is not default y.

Make it default y and also depend on EXPERT, as dracut use is likely
widespread.
