2c81f0f6d3 bus: ti-sysc: Fix iterating over clocks
Commit d878970f6c ("bus: ti-sysc: Add separate functions for handling
clocks") separated handling of optional clocks from the main clocks, but
introduced an issue where we do not necessarily allocate a slot for both
fck and ick clocks, but still assume fixed slots for enumerating over the
clocks.

Let's fix the issue by ensuring we always have slots for both fck and ick
even if we don't use ick, and don't attempt to enumerate optional clocks
if not allocated.

In the long run we might want to simplify things a bit by only allocating
space only for the optional clocks as we have only few devices with
optional clocks.

Commit 03856e928b ("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.

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()

c7d8669f46 bus: ti-sysc: Fix watchdog quirk handling
I noticed that when probed with ti-sysc, watchdog can trigger on am3, am4
and dra7 causing a device reset.

Turns out I made several mistakes implementing the watchdog quirk handling:

1. We must do both writes to spr register

2. We must also call the reset quirk on disable

3. On am3 and am4 we need to also set swsup quirk flag

I probably only tested this earlier with watchdog service running when the
watchdog never gets disabled.

f213729f67 counter: new TI eQEP driver
This adds a new counter driver for the Texas Instruments Enhanced
Quadrature Encoder Pulse (eQEP) module.

Only very basic functionality is currently implemented - only enough to
be able to read the position. The actual device has many more features
which can be added to the driver on an as-needed basis.

It is not possible to read the QEPA/B signal values in hardware, so
that feature is omitted.

The TI_PWMSS kernel option is selected in Kconfig to enable the parent
bus, which is needed for power management.

The TI PWMSS driver is a simple bus driver for providing power
power management for the PWM peripherals on TI AM33xx SoCs, namely
eCAP, eHRPWM and eQEP. The eQEP is a counter rather than a PWM, so
it does not make sense to have the bus driver in the PWM subsystem
since the PWMSS is not exclusive to PWM devices.

cdc56c1129 bus: ti-sysc: avoid toggling power state of module during probe
Current implementation for ti-sysc powers down the module once module
init is complete. However, right after power is disabled, it is enabled
via runtime PM. This is unnecessary so avoid it by re-ordering the
events a bit; move powering down of the module post runtime PM enable
which makes sure the use counts are maintained properly and there is
no extra power down/up sequence for the module.

There seems to be unnecessary extra hardreset line toggling applied

bf59ebbeac bus: ti-sysc: re-order reset and main clock controls
The main clocks and reset controls have a hardware level dependency,
where one can't transition state without the other one transitioning.
Because we don't have the dependency implemented in software, we must
ensure the ordering of these two is done properly; they way this is
handled is that clocks transition on software level without delay,
and the status is only polled on reset side. Because of this, we must
re-order the main clock and reset handling on the ti-sysc driver.

f97c81dc6c ARM: SoC: late updates for v5.4
This is some material that we picked up into our tree late or
 that had complex inter-depondencies. The fact that there are these
 interdependencies tends to meant that these are often actually the most
 interesting new additions:
 
 The new Aspeed AST2600 baseboard management controller is added, this
 is a Cortex-A7 based follow-up to the ARM11 based AST2500 and had some
 dependencies on other device drivers.
 
 After many years, support for the MMP2 based OLPC XO-1.75 finally makes
 it into the kernel.
 
 The Armada 3720 based Turris Mox open source router platform is a late
 addition and it follows some preparatory work across multiple branches.
 
 The OMAP2+ platform had some large-scale cleanup involving driver
 changes and DT changes, here we finish it off, dropping a lot of the
 now-unused platform data.
 
 The TI K3 platform that got added for 5.3 gains a lot more support
 for individual bits on the SoC, this part just came late for the
 merge window.

Pull ARM SoC late updates from Arnd Bergmann:
 "This is some material that we picked up into our tree late or that had
  complex inter-depondencies. The fact that there are these
  interdependencies tends to meant that these are often actually the
  most interesting new additions:

   - The new Aspeed AST2600 baseboard management controller is added,
     this is a Cortex-A7 based follow-up to the ARM11 based AST2500 and
     had some dependencies on other device drivers.

   - After many years, support for the MMP2 based OLPC XO-1.75 finally
     makes it into the kernel.

   - The Armada 3720 based Turris Mox open source router platform is a

399eb9b6cb ARM: SoC driver updates for v5.4
The branch contains driver changes that are tightly
 connected to SoC specific code. Aside from smaller
 cleanups and bug fixes, here is a list of the notable
 changes.
 
 New device drivers:
 
 - The Turris Mox router has a new "moxtet" bus driver
   for its on-board pluggable extension bus. The
   same platform also gains a firmware driver.
 
 - The Samsung Exynos family gains a new Chipid driver
   exporting using the soc device sysfs interface
 
 - A similar socinfo driver for Qualcomm Snapdragon
   chips.
 
 - A firmware driver for the NXP i.MX DSP IPC protocol
   using shared memory and a mailbox
 
 Other changes:
 
 - The i.MX reset controller driver now supports the
   NXP i.MX8MM chip
 
 - Amlogic SoC specific drivers gain support for
   the S905X3 and A311D chips
 
 - A rework of the TI Davinci framebuffer driver to
   allow important cleanups in the platform code
 
 - A couple of device drivers for removed ARM SoC
   platforms are removed. Most of the removals were
   picked up by other maintainers, this contains
   whatever was left.

a4c8723a16 bus: ti-sysc: Remove unpaired sysc_clkdm_deny_idle()
Commit d098913a10 ("bus: ti-sysc: Fix clock handling for no-idle
quirks") fixed handling for no-idle quirk modules that are not enabled
by the bootloader.

But it also caused unpaired clockdomain calls that won't allow idling
the system. That's because clkdm_allow_idle_nolock() and
clkdm_deny_idle_nolock() have usage count with clkdm->forcewake_count.

Let's drop the unpaired sysc_clkdm_deny_idle() to fix idling of devices.

We can currently get "Unable to handle kernel paging request at

(__clk_get_hw) from [<c0138ebc>] (ti_sysc_find_one_clockdomain+0x18/0x34)

(sysc_probe) from [<c065c6ac>] (platform_drv_probe+0x58/0xa8)

Let's add IS_ERR checks to ti_sysc_clkdm_init() as And let's start treating
clk_get() with -ENOENT as a proper error. If the clock name is specified
in device tree we must succeed with clk_get() to continue. For modules with
no clock names specified in device tree we will just ignore the clocks.

d098913a10 bus: ti-sysc: Fix clock handling for no-idle quirks
NFSroot can fail on dra7 when cpsw is probed using ti-sysc interconnect
target module driver as reported by Keerthy.

Device clocks and the interconnect target module may or may not be
enabled by the bootloader on init, but we currently assume the clocks
and module are on from the bootloader for "ti,no-idle" and
"ti,no-idle-on-init" quirks as reported by Grygorii Strashko.

Let's fix the issue by always enabling clocks init, and
never disable them for "ti,no-idle" quirk. For "ti,no-idle-on-init"
quirk, we must decrement the usage count later on to allow PM
runtime to idle the module if requested.

The function weim_probe() references

This is often because weim_probe lacks a __init

bff00fdf03 i.MX drivers update for 5.4:
- A series from Anson Huang to add UID support for i.MX8 SoC and SCU
    drivers.
  - A series from Daniel Baluta to add DSP IPC driver for communication
    between host AP (Linux) and the firmware running on DSP embedded in
    i.MX8 SoCs.
  - A small fix for GPCv2 error code printing.
  - Switch from module_platform_driver_probe() to module_platform_driver()
    for imx-weim driver, as we need the driver to probe again when device
    is present later.
  - Add optional burst clock mode support for imx-weim driver.

4a92f07816 bus: imx-weim: use module_platform_driver()
Switch from module_platform_driver_probe() to module_platform_driver().
The former is not suitable for booting with device tree as the driver
will be registered before the device and thus won't be probed again
when the device is present.
