We can now init system timers using the dmtimer and 32k counter
based on only devicetree data and drivers/clocksource timers.
Let's configure the clocksource and clockevent, and drop the old
unused platform data.
As we're just dropping platform data, and the early platform data
init is based on the custom ti,hwmods property, we want to drop
both the platform data and ti,hwmods property in a single patch.
Since the dmtimer can use both 32k clock and system clock as the
source, let's also configure the SoC specific default values. The
board specific dts files can reconfigure these with assigned-clocks
and assigned-clock-parents as needed.

This allows us to move the SoCs to probe system timers one SoC
at at time. As arch/arm/mach-omap2/timer.c will be eventually gone,
let's just add omap_init_time_of() to board-generic.c directly.

Core and userspace API:
- The userspace API KFIFOs have been imoproved with locks that
do not block interrupts. This makes us better at getting
events to userspace without blocking or disturbing new events
arriving in the same time. This was reviewed by the KFIFO
maintainer Stefani. This is a generic improvement which
paves the road for similar improvements in other subsystems.
- We provide a new ioctl() for monitoring changes in the line
information, such as when multiple clients are taking lines
and giving them back, possibly reconfiguring them in the
process: we can now monitor that and not get stuck with stale
static information.
- An example tool 'gpio-watch' is provided to showcase this
functionality.
- Timestamps for events are switched to ktime_get_ns() which is
monotonic. We previously had a 'realtime' stamp which could
move forward and *backward* in time, which probably would just
cause silent bugs and weird behaviour. In the long run we
see two relevant timestamps: ktime_get_ns() or the timestamp
sometimes provided by the GPIO hardware itself, if that
exists.
- Device Tree overlay support for GPIO hogs. On systems that
load overlays, these overlays can now contain hogs, and will
then be respected.
- Handle pin control interaction with nonexisting pin ranges
in the GPIO library core instead of in the individual
drivers.
New drivers:
- New driver for the Mellanox BlueField 2 GPIO controller.
Driver improvements:
- Introduce the BGPIOF_NO_SET_ON_INPUT flag to the generic
MMIO GPIO library and use this flag in the MT7621 driver.
- Texas Instruments OMAP CPU power management improvements,
such as blocking of idle on pending GPIO interrupts.

We need to check for errors when calling cpu_pm_enter() and
cpu_cluster_pm_enter(). And we need to bail out on errors as
otherwise we can enter a deeper idle state when not desired.
I'm not aware of the lack of error handling causing issues yet,
but we need this at least for blocking deeper idle states when
a GPIO instance has pending interrupts.

request_irq() is preferred over setup_irq(). Invocations of setup_irq()
occur after memory allocators are ready.
Per tglx[1], setup_irq() existed in olden days when allocators were not
ready by the time early interrupts were initialized.
Hence replace setup_irq() by request_irq().

In order for am335x and am437x to properly enter deeper c-states in
cpuidle they must always call into the sleep33/43xx suspend code and
also sometimes invoke the wkup_m3_ipc driver. These are both controlled
by the pm33xx module so we must provide a method for the platform code
to call back into the module when it is available as the core cpuidle
ops that are invoked by the cpuidle-arm driver must remain as built in.
Extend the init platform op to take an idle function as an argument so
that we can use this to call into the pm33xx module for c-states that
need it. Also add a deinit op so we can unregister this idle function
from the PM core when the pm33xx module gets unloaded.

am335x and am437x can now make use of the generic cpuidle-arm driver.
This requires that we define init and suspend ops to be passed set as
the cpuidle ops for the SoC. These ops are invoked directly at the last
stage of the cpuidle-arm driver in order to allow low level platform
code to run and bring the CPU the rest of the way into it's desired idle
state. It is required that the CPUIDLE_METHOD_OF_DECLARE be called from
code that is built in so define these ops in pm33xx-core where the
always built-in portion of the PM code for these SoCs lives.
Additionally, although an soc_suspend function is already exposed by the
pm33xx platform code, it contains additional operations needed for full
SoC suspend beyond what is needed for a relatively simple CPU suspend
needed during cpuidle. To get around this introduce cpu_suspend ops to
be used by the am335x and am437x PM driver for the last stage of cpuidle
path.

Recent omap changes added runtime checks to use omap_smccc_smc()
when optee is configured in dts. As the omap-secure code can be
built for ARMv6 only without ARMv7 and use custom smc calls, we
now get a build error:
omap-secure.c:(.text+0x94): undefined reference to `__arm_smccc_smc'
As there secure calls are not used for ARMv6, we should not build
secure-common, and not call omap_secure_init() for omap2.

We need to know SoC type and features for cases where the same SoC
may be installed in various versions on the same board and would need
a separate dts file otherwise for the different variants.
For example, am3703 is pin compatible with omap3630, but has sgx and
iva accelerators disabled. We must not try to access the sgx or iva
module registers on am3703, and need to set the unavailable devices
disabled early.
Let's also detect omap3430 as that is needed for display subsystem
(DSS) reset later on, and GP vs EMU or HS devices. Further SoC
specific disabled device detection can be added as needed, such as
dra71x vs dra76x rtc and usb4.

We can currently get a cryptic warning sysc_fields (ptrval) != (ptrval)
if the legacy platform data has no sysc_fields defined while the newer
dts data has them. This warning appears only when booting still with
legacy "ti,hwmods" custom property set. This can happen at least with
DSS related modules where we may not have sysc_fields defined in the
in the legacy data.
Let's not error out on missing legacy data sysc_fields, and show a more
descriptive warning for other cases.

Both CAL and VIP rely on this clock domain. But CAL DPHY require
LVDSRX_96M_GFCLK to be active. When this domain is set to HWSUP the
LVDSRX_96M_GFCLK is on;y active when VIP1 clock is also active. If only
CAL on DRA72x (which uses the VIP2 clkctrl) probes the CAM domain is
enabled but the LVDSRX_96M_GFCLK is left gated. Since LVDSRX_96M_GFCLK
is sourcing the input clock to the DPHY then actual frame capture cannot
start as the phy are inactive.
So we either have to also enabled VIP1 even if we don't intend on using
it or we need to set the CAM domain to use SWSUP only.
This patch implements the latter.

We can now probe devices with ti-sysc interconnect driver and dts
data. Let's drop the related platform data and custom ti,hwmods
dts property.
As we're just dropping data, and the early platform data init
is based on the custom ti,hwmods property, we want to drop both
the platform data and ti,hwmods property in a single patch.

omap_secure_init() is now called from all OMAP2+ platforms during their
init_early() call. This function is in omap-secure.o so include that
in the build for these platforms.

During suspend CPU context may be lost in both non-secure and secure CPU
states. The kernel can handle saving and restoring the non-secure context
but must call into the secure side to allow it to save any context it may
lose. Add these calls here.
Note that on systems with OP-TEE available the suspend call is issued to
OP-TEE using the ARM SMCCC, but the resume call is always issued to the
ROM. This is because on waking from suspend the ROM is restored as the
secure monitor. It is this resume call that instructs the ROM to restore
OP-TEE, all subsequent calls will be handled by OP-TEE and should use the
ARM SMCCC.

On High-Security(HS) OMAP2+ class devices a couple actions must be
performed from the ARM TrustZone during boot. These traditionally can be
performed by calling into the secure ROM code resident in this secure
world using legacy SMC calls. Optionally OP-TEE can replace this secure
world functionality by replacing the ROM after boot. ARM recommends a
standard calling convention is used for this interaction (SMC Calling
Convention). We check for the presence of OP-TEE and use this type of
call to perform the needed actions, falling back to the legacy OMAP ROM
call if OP-TEE is not available.

We can now probe devices with ti-sysc interconnect driver and dts
data, and can continue dropping the related platform data and custom
ti,hwmods dts property for various devices.
And related to that, we finally can remove the legacy sdma support in
favor of using the dmaengine driver only. I was planning to send the
sdma changes separately, but that would have produced a pile of
pointless merge conflicts, so I decided it's best to resolve it locally.
After all, the sdma series also ends up removing the related platform
data.
Note that this series is based on omap-for-v5.6/ti-sysc-dt-signed branch
as it depends for dts data being in place.
