The da850 family of processors has an async3 clock domain that can be
muxed to either pll0_sysclk2 or pll1_sysclk2. Now that the davinci clocks
have a set_parent callback, we can use this to control the async3 mux
instead of a stand-alone function.

This adds a new async3_clk and sets the appropriate child clocks. The
default is use to pll1_sysclk2 since it is not affected by processor
frequency scaling.

Merge tag 'for-v4.7/omap-hwmod-a' of git://git.kernel.org/pub/scm/linux/kernel/git/pjw/omap-pending into omap-for-v4.7/soc

ARM: OMAP2+: first set of hwmod changes for v4.7

For the DRA7xx platform, add IP block data for the McASP, PWMSS,
and GPTimer12 IP blocks.  Add lock and unlock functions for the
RTC IP blocks on the DRA7xx, AM33xx, and AM43xx devices.  And add
a fix for the hwmod core for device driver unbind operations for
IP blocks with hardreset lines.

Basic build, boot, and PM test results are available here:

http://www.pwsan.com/omap/testlogs/omap-hwmod-a-for-v4.7/20160410132119/

Note that the testbed here does not have the DRA7xx board included yet.

Commit edf41009 ("ARM: shmobile: sh7372 dtsi: Remove Legacy
file") removed the DTS for the last shmobile SoC with a Cortex A8 CPU
core (sh7372 aka SH-Mobile AP4), hence drop support for it in the
loops-per-jiffy preset code.

As "div" is always 1 for supported contemporary ARM processors, we can
simplify the code:
  - Absorb shmobile_setup_delay_hz(), which was always called with
    mult = div = 1,
  - Return earlier if the Cortex A7/A15 arch timer exists and support is
    enabled.

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.
