We have dts property for "ti,sysc-delay-us", and we're using it, but the
wait after OCP softreset only happens if devices are probed in legacy mode.
Let's add a delay after writing the OCP softreset when specified.

Commit 03856e928b0e ("bus: ti-sysc: Handle mstandby quirk and use it for
musb") added quirk handling for mstandby quirk but did not consider that
we also need a quirk variant for SYSC_QUIRK_FORCE_MSTANDBY.
We need to use forced idle mode for both SYSC_QUIRK_SWSUP_MSTANDBY and
SYSC_QUIRK_FORCE_MSTANDBY, but SYSC_QUIRK_SWSUP_MSTANDBY also need to
additionally also configure no-idle mode when enabled.

Few ti-sysc related fixes for v5.5 merge window Just few minor changes that can be merged when suitable, but would be good to have these in v5.5-rc1 to remove dependencies between branches for more changes later on in v5.6: - Add quirk handling for AESS (Audio Engine Sub System) - We want to drop the useless gptimer option for omap4 as there are local timers - A minor error path handling improvment for sysc_child_add_named_clock() that will make further patching a bit easier * tag 'omap-for-v5.5/ti-sysc-late-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: bus: ti-sysc: Adjust exception handling in sysc_child_add_named_clock() ARM: OMAP2+: Drop useless gptimer option for omap4 bus: ti-sysc: Add module enable quirk for audio AESS Link: https://lore.kernel.org/r/pull-1574273726-31367@atomide.com Signed-off-by: Olof Johansson <olof@lixom.net>
Pull ARM SoC driver updates from Olof Johansson:
"Various driver updates for platforms:
- A larger set of work on Tegra 2/3 around memory controller and
regulator features, some fuse cleanups, etc..
- MMP platform drivers, in particular for USB PHY, and other smaller
additions.
- Samsung Exynos 5422 driver for DMC (dynamic memory configuration),
and ASV (adaptive voltage), allowing the platform to run at more
optimal operating points.
- Misc refactorings and support for RZ/G2N and R8A774B1 from Renesas
- Clock/reset control driver for TI/OMAP
- Meson-A1 reset controller support
- Qualcomm sdm845 and sda845 SoC IDs for socinfo"

ARM64: hisi: SoC driver updates for 5.5
- check the LOGIC_PIO_INDIRECT region ops at registration instead of
in the IO port accessors to optimise the lib/ligic_pio.c
- add the hisi LPC driver to the build test for the other architectures
except ALPHA, C6X, HEXAGON and PARISC as they do not define {read,write}sb
by updating the hisi LPC Kconfig and adding a dummy PIO_INDIRECT_SIZE
- clean the sparse complains of the hisi LPC driver
- build logic_pio into a lib to avoid including in the vmlinux when not
referenced

Currently the driver will only ever be built for ARM64 because it selects
CONFIG_INDIRECT_PIO, which itself depends on ARM64.
Expand build test coverage for the driver to other architectures by only
selecting CONFIG_INDIRECT_PIO for ARM64, when we really want it.
We don't include ALPHA, C6X, HEXAGON, and PARISC architectures as they
don't define {read, write}sb.
