Tony Lindgren e64c021fd9 bus: ti-sysc: Rename clk related quirks to pre_reset and post_reset quirks
The clk_disable_quirk and clk_enable_quirk should really be called
pre_reset_quirk and post_reset_quirk to avoid confusion like we had
with hdq1w reset.

Let's also rename the related functions so the code is easier to follow.
Note that we also have reset_done_quirk that is needed in some cases
after checking the separate register for reset done bit.

Tony Lindgren aec551c7a0 bus: ti-sysc: Fix 1-wire reset quirk
Because of the i2c quirk we have the reset quirks named in a confusing
way. Let's fix the 1-wire quirk accordinlyg. Then let's switch to using
better naming later on.

Tony Lindgren 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.

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()

Merge tag 'omap-for-v5.5/ti-sysc-late-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into arm/fixes

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

John Garry 3e5cd20d4e bus: hisi_lpc: Expand build test coverage
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.

Ioana Ciornei 1ac210d128 bus: fsl-mc: add the fsl_mc_get_endpoint function
Using the newly added fsl_mc_get_endpoint function a fsl-mc driver can
find its associated endpoint (another object at the other link of a MC
firmware link).

The API will be used in the following patch in order to discover the
connected DPMAC object of a DPNI.

Also, the fsl_mc_device_lookup function is made available to the entire
fsl-mc bus driver and not just for the dprc driver.

Tony Lindgren 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.

David Lechner 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.

David Lechner 7cabf9251a bus/ti-pwmss: move TI PWMSS driver from PWM to bus subsystem
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.

Tero Kristo 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.

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.

This is some material that we picked up into our tree late or

 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

Tony Lindgren 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.

Tony Lindgren 2783d0638a bus: ti-sysc: Fix handling of invalid clocks
We can currently get "Unable to handle kernel paging request at
virtual address" for invalid clocks with dts node but no driver:

(__clk_get_hw) from [<c0138ebc>] (ti_sysc_find_one_clockdomain+0x18/0x34)
(ti_sysc_find_one_clockdomain) from [<c0138f0c>] (ti_sysc_clkdm_init+0x34/0xdc)
(ti_sysc_clkdm_init) from [<c0584660>] (sysc_probe+0xa50/0x10e8)
(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.

Masahiro Yamada ef92bfdaa7 bus: uniphier-system-bus: use devm_platform_ioremap_resource()
Replace the chain of platform_get_resource() and devm_ioremap_resource()
with devm_platform_ioremap_resource().

This allows to remove the local variable for (struct resource *), and
have one function call less.

Tony Lindgren 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.

Arnd Bergmann 3b1261fb72 bus: imx-weim: remove incorrect __init annotations
The probe function is no longer __init, so anything it calls now
must also be available at runtime, as Kbuild points out when building
with clang-9:

WARNING: vmlinux.o(.text+0x6e7040): Section mismatch in reference from the function weim_probe() to the function .init.text:imx_weim_gpr_setup()
The function weim_probe() references
the function __init imx_weim_gpr_setup().
This is often because weim_probe lacks a __init
annotation or the annotation of imx_weim_gpr_setup is wrong.

WARNING: vmlinux.o(.text+0x6e70f0): Section mismatch in reference from the function weim_probe() to the function .init.text:weim_timing_setup()
The function weim_probe() references
the function __init weim_timing_setup().
This is often because weim_probe lacks a __init
annotation or the annotation of weim_timing_setup is wrong.

Remove the remaining __init markings that are now wrong.
