commit 8ac686d7dfed721102860ff2571e6b9f529ae81a upstream.

The assigned parent clocks should be normally specified in the consumer
device's DT node, this ensures respective driver always sees correct clock
settings when required.

This patch fixes regression in audio subsystem on Odroid XU3/XU4 boards
that appeared after commits:

commit 647d04f8e07a ("ASoC: samsung: i2s: Ensure the RCLK rate is properly determined")
commit 995e73e55f46 ("ASoC: samsung: i2s: Fix rclk_srcrate handling")
commit 48279c53fd1d ("ASoC: samsung: i2s: Prevent external abort on exynos5433 I2S1 access")

Without this patch the driver gets wrong clock as the I2S function clock
(op_clk) in probe() and effectively the clock which is finally assigned
from DT is not being enabled/disabled in the runtime resume/suspend ops.

Without the above listed commits the EXYNOS_I2S_BUS clock was always set
as parent of CLK_I2S_RCLK_SRC regardless of DT settings so there was no issue
with not enabled EXYNOS_SCLK_I2S.

Pull ARM SoC fixes from Olof Johansson:
 "The usual batch; most of them are DT tweaks to fix misdescribed
  hardware. Beyond that:

   - A bugfix for MMP2 CPU detection, it's been there quite a while but
     makes sense to fix now anyway.

   - Some power management tweaks:
      + disabling of CPU idle power state on Marvell Armada 7K/8K
        (Macchiatobin et al)
      + Increase of minimum voltage on BananaPi M3
      + Tweak of power ramp time for DVFS on NXP/Freescale i.MX7SX

   - A couple of MAINTAINER updates:
      + MMP has a new volunteer to look after it
      + Mediatek adds a few keywords, IRC channel and wiki URL"

i.MX fixes for 4.20, round 3:
 - A couple of fixes on imx7d-pico and imx7d-nitrogen7 boards to correct
   the description of the Wifi clock.
 - Change SW2ISO count to get a safer ARM LDO ramp-up time, so that
   different boards can be covered. This fixes the ARM LDO failure seen
   on some customer boards.

Marek Szyprowski reported problems with CPU hotplug in current kernels.
This was tracked down to the processor vtables being located in an
init section, and therefore discarded after kernel boot, despite being
required after boot to properly initialise the non-boot CPUs.

Arrange for these tables to end up in .rodata when required.

According to bindings/regulator/fixed-regulator.txt the 'clocks' and
'clock-names' properties are not valid ones.

In order to turn on the Wifi clock the correct location for describing
the CLKO2 clock is via a mmc-pwrseq handle, so do it accordingly.

The sw2iso count should cover ARM LDO ramp-up time,
the MAX ARM LDO ramp-up time may be up to more than
100us on some boards, this patch sets sw2iso to 0xf
(~384us) which is the reset value, and it is much
more safe to cover different boards, since we have
observed that some customer boards failed with current
setting of 0x2.

The Wifi chip should be clocked by a 32kHz clock coming from i.MX7D
CLKO2 output pin, so describe the pinmux and clock hierarchy in the
device tree to allow the Wifi chip to be properly clocked.

Managed to successfully test Wifi with such change. Used the standard
nvram.txt file provided by TechNexion, which selects an external 32kHz
clock for the Wifi chip by default.
