Pull SoC driver updates from Arnd Bergmann:
 "This is the first half of the driver changes:

   - A treewide interface change to the "syscore" operations for power
     management, as a preparation for future Tegra specific changes

   - Reset controller updates with added drivers for LAN969x, eic770 and
     RZ/G3S SoCs

   - Protection of system controller registers on Renesas and Google
     SoCs, to prevent trivially triggering a system crash from e.g.
     debugfs access

   - soc_device identification updates on Nvidia, Exynos and Mediatek

   - debugfs support in the ST STM32 firewall driver

   - Minor updates for SoC drivers on AMD/Xilinx, Renesas, Allwinner, TI

   - Cleanups for memory controller support on Nvidia and Renesas"

The PWM signal from the LPG channel can be routed to PMIC GPIOs with
proper GPIO configuration, and it is not necessary to enable the
TRILED channel in that case. This also applies to the LPG channels
that mapped to TRILED channels. Additionally, enabling the TRILED
channel unnecessarily would cause a voltage increase in its power
supply. Hence remove it.

Add support for optional GPIO-based enable pin control to PWM LED driver.
Some PWM LED driver chips like TPS92380 and LT3743 require a separate
enable signal in addition to PWM control. Implement support for such
GPIO control through the "enable-gpios" device tree property, activating
the pin when LED brightness is non-zero and deactivating it when off.

Tested on i.MX8MP EVK with TPS92380 LED driver chip

Several drivers can benefit from registering per-instance data along
with the syscore operations. To achieve this, move the modifiable fields
out of the syscore_ops structure and into a separate struct syscore that
can be registered with the framework. Add a void * driver data field for
drivers to store contextual data that will be passed to the syscore ops.

Currently if a user enqueues a work item using schedule_delayed_work() the
used wq is "system_wq" (per-cpu wq) while queue_delayed_work() use
WORK_CPU_UNBOUND (used when a cpu is not specified). The same applies to
schedule_work() that is using system_wq and queue_work(), that makes use
again of WORK_CPU_UNBOUND.

This lack of consistency cannot be addressed without refactoring the API.

This patch continues the effort to refactor worqueue APIs, which has begun
with the change introducing new workqueues and a new alloc_workqueue flag:

commit 128ea9f6ccfb ("workqueue: Add system_percpu_wq and system_dfl_wq")
commit 930c2ea566af ("workqueue: Add new WQ_PERCPU flag")

system_wq should be the per-cpu workqueue, yet in this name nothing makes
that clear, so replace system_wq with system_percpu_wq.

The old wq (system_wq) will be kept for a few release cycles.

sysfs_emit() is preferred to format sysfs output as it provides better

The function netxbig_gpio_ext_get() acquires GPIO descriptors but
fails to release them when errors occur mid-way through initialization.
The cleanup callback registered by devm_add_action_or_reset() only
runs on success, leaving acquired GPIOs leaked on error paths.

Add goto-based error handling to release all acquired GPIOs before
returning errors.

If a GPIO is used to control the chip's enable pin, it needs to be pulled
high before any i2c communication is attempted.

Currently, the enable GPIO handling is not correct.

Assume the enable GPIO is low when the probe function is entered. In this
case the device is in SHUTDOWN mode and does not react to i2c commands.

During probe the following sequence happens:
 1. The call to lp50xx_reset() on line 548 has no effect as i2c is not
    possible yet.
 2. Then - on line 552 - lp50xx_enable_disable() is called. As
    "priv->enable_gpio“ has not yet been initialized, setting the GPIO has
    no effect. Also the i2c enable command is not executed as the device
    is still in SHUTDOWN.
 3. On line 556 the call to lp50xx_probe_dt() finally parses the rest of
    the DT and the configured priv->enable_gpio is set up.

As a result the device is still in SHUTDOWN mode and not ready for
operation.

Split lp50xx_enable_disable() into distinct enable and disable functions
to enforce correct ordering between enable_gpio manipulations and i2c
commands.
Read enable_gpio configuration from DT before attempting to manipulate
enable_gpio.
Add delays to observe correct wait timing after manipulating enable_gpio
and before any i2c communication.
