Ederson de Souza 0295edf834 soc/arm/microchip_mec/mec1501: Initialise GPIO after interrupts
Since bb590b5b6e, which enforces a more consistent ordering of
initialisation for devices, the SOC initialisation was happening after
GPIO initialisation. This caused interrupts to stop working on GPIO
input.

This patch fixes that by increasing the default GPIO initialisation
priority, so that it happens after SOC.

Jay Vasanth c7e0d727d7 drivers: clock: Microchip XEC clock driver add MEC15xx support
Add support for Microchip MEC15xx to the XEC clock control driver.
MEC15xx 32KHz clock support uses the same 32KHz source for both the
PLL and peripherals. MEC152x does not include the PCR clock monitor
present in MEC172x.  MEC15xx and MEC172x support internal silicon
oscillator, parallel and single ended crystal inputs, and the
32KHZ_PIN input. MEC152x supports fall back to internal silicon
OSC when VTR and 32KHZ_PIN are turned off. Therefore in MEC152x the
internal silicon oscillator can only be disabled if using an external
32KHz which is always on. For MEC152x the driver will only use the
PLL source clock device tree value.

Gerard Marull-Paretas 95fb0ded6b kconfig: remove Enable from boolean prompts
According to Kconfig guidelines, boolean prompts must not start with
"Enable...". The following command has been used to automate the changes
in this patch:

sed -i "s/bool \"[Ee]nables\? \(\w\)/bool \"\U\1/g" **/Kconfig*

Gerard Marull-Paretas 7746abdc39 soc: arm: microchip_mec: mec1501: remove SOC_POWER_MANAGEMENT
Remove a redundant symbol that was used as a proxy to enable CONFIG_PM.
If an application needs to enable PM, it should just enable PM subsystem
Kconfig options. Furthermore, there's no clue "SOC_POWER_MANAGEMENT" is
a Microchip specific option.

Tom Burdick f523c336ef pm: Use stats subsys for tracking system states
Uses the stats subsys to provide simple but useful debugging stats for
power management state changes and timing.

Removes the no longer needed PM_DEBUG config option

Replaces the use of PM_DEBUG for a test clock output pin for mec1501 and
adds in its place an SoC Kconfig option to enable it.

Adds a STATS_SET macro for assigning a value to a stat group field

Ulf Magnusson 87e917a925 kconfig: Remove redundant 'default n' and 'prompt' properties
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.

Also replace some

    config
    	prompt "foo"
    	bool/int

with the more common shorthand

    config
    	bool/int "foo"

See the 'Style recommendations and shorthands' section in
https://docs.zephyrproject.org/latest/guides/kconfig/index.html.

Ulf Magnusson bd6e04411e kconfig: Clean up header comments and make them consistent
Use this short header style in all Kconfig files:

    # <description>

    # <copyright>
    # <license>

    ...

Also change all <description>s from

    # Kconfig[.extension] - Foo-related options

to just

    # Foo-related options

It's clear enough that it's about Kconfig.

The <description> cleanup was done with this command, along with some
manual cleanup (big letter at the start, etc.)

        xargs sed -i -E '1 s/#\s*Kconfig[\w.-]*\s*-\s*/# /'

Ulf Magnusson 975de21858 kconfig: Global whitespace/consistency cleanup
Clean up space errors and use a consistent style throughout the Kconfig
files. This makes reading the Kconfig files more distraction-free, helps
with grepping, and encourages the same style getting copied around
everywhere (meaning another pass hopefully won't be needed).

Go for the most common style:

 - Indent properties with a single tab, including for choices.

   Properties on choices work exactly the same syntactically as
   properties on symbols, so not sure how the no-indentation thing
   happened.

 - Indent help texts with a tab followed by two spaces

 - Put a space between 'config' and the symbol name, not a tab. This
   also helps when grepping for definitions.

 - Do '# A comment' instead of '#A comment'

I tweaked Kconfiglib a bit to find most of the stuff.

Some help texts were reflowed to 79 columns with 'gq' in Vim as well,
though not all, because I was afraid I'd accidentally mess up
formatting.

Scott Worley bdaab8cfa0 drivers : timer : Add MEC1501 32KHz kernel timer driver
Add a kernel timer driver for the MEC1501 32KHz RTOS timer.
This timer is a count down 32-bit counter clocked at a fixed
32768 Hz. It features one-shot, auto-reload, and halt count down
while the Cortex-M is halted by JTAG/SWD. This driver is based
on the new Intel local APIC driver. The driver was tuned for
accuracy at small sleep values. Added a work-around for RTOS
timer restart issue. RTOS timer driver requires board ticks per
second to be 32768 if tickless operation is configured.
