Ramakrishna Pallala e1639b5345 device: Extend device_set_power_state API to support async requests
The existing device_set_power_state() API works only in synchronous
mode and this is not desirable for devices(ex: Gyro) which take
longer time (few 100 mSec) to suspend/resume.

To support async mode, a new callback argument is added to the API.
The device drivers can asynchronously suspend/resume and call the
callback function upon completion of the async request.

This commit adds the missing callback parameter to all the drivers
to make it compliant with the new API.

Patrik Flykt 4344e27c26 all: Update reserved function names
Update reserved function names starting with one underscore, replacing
them as follows:
   '_k_' with 'z_'
   '_K_' with 'Z_'
   '_handler_' with 'z_handl_'
   '_Cstart' with 'z_cstart'
   '_Swap' with 'z_swap'

This renaming is done on both global and those static function names
in kernel/include and include/. Other static function names in kernel/
are renamed by removing the leading underscore. Other function names
not starting with any prefix listed above are renamed starting with
a 'z_' or 'Z_' prefix.

Function names starting with two or three leading underscores are not
automatcally renamed since these names will collide with the variants
with two or three leading underscores.

Various generator scripts have also been updated as well as perf,
linker and usb files. These are
   drivers/serial/uart_handlers.c
   include/linker/kobject-text.ld
   kernel/include/syscall_handler.h
   scripts/gen_kobject_list.py
   scripts/gen_syscall_header.py

Erwan Gouriou f502da5b08 drivers/interrupt_controller: stm32: Remove RTC_Alarm IRQ handling
RTC_Alarm IRQ is mentioned as an exti interrupt in documentation,

Marti Bolivar 58d8afb476 interrupt_controller: RV32M1: add intmux driver / DT bindings
Add a level 2 interrupt controller for the RV32M1 SoC. This uses the
INTMUX peripheral.

As a first customer, convert the timer driver over to using this,
adding nodes for the LPTMR peripherals. This lets users select the
timer instance they want to use, and what intmux channel they want to
route its interrupt to, using DT overlays.

Marti Bolivar 0aa87e15bb drivers: interrupt_controller: multi-level improvements
Some extensions to the multi-level interrupt controller are required
to support SoCs with more than four level 2 interrupt "aggregators".

Extend existing support to allow at most 8 level 2 or level 3
aggregators. Use Kconfig macro templates to cut down on boilerplate.
Try to clarify some aspects of the Kconfig help while we're at it, and
change the type of options which count things or are table offsets
from "hex" to "int", so that the generated .config is easier to read.

Finally, make some improvements to gen_isr_tables.py while we are
here. In particular, move some assignments around to cut down on
duplicated work, don't check for symbols we know must exist, and
improve the debug logging output's readability.

Andrzej Głąbek 20202902f2 dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig
These changes were obtained by running a script  created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:

1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
   #define X Y)
3. Check if that name is also the name of a Kconfig option
   3.a If it is, then do nothing
   3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
       has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
   (.c, .h, .ld)

Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.

Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

Ulf Magnusson 8cf8db3a73 Kconfig: Use a short, consistent style for prompts
Consistently use

    config FOO
            bool/int/hex/string "Prompt text"

instead of

    config FOO
            bool/int/hex/string
            prompt "Prompt text"

(...and a bunch of other variations that e.g. swapped the order of the
type and the 'prompt', or put other properties between them).

The shorthand is fully equivalent to using 'prompt'. It saves lines and
avoids tricking people into thinking there is some semantic difference.

Most of the grunt work was done by a modified version of
https://unix.stackexchange.com/questions/26284/

Wayne Ren 528c960ae7 arch: arc: Add the support of secure mode for em
In ARC's SecureShield, a new secure mode (currently only em) is added.
The secure/normal mode is orthogonal to kernel/user mode. The
differences between secure mode and normal mode are following:

* different irq stack frame. so need to change the definition of
  _irq_stack_frame, assembly code.

* new aux regs, e.g, secure status(SEC_STAT), secure vector base
  (VECT_BASE_S)

* interrupts and exceptions, secure mode has its own vector base;
  interrupt can be configured as secure or normal through the
  interrupt priority aux reg.

* secure timers. Two secure timers (secure timer 0 and timer 1) are
  added.Here, for simplicity and backwards compatibility original
  internal timers (timer 0 and timer1) are used as sys clock of zephyr

* on reset, the processor is in secure mode and secure vector base is
  used.

Note: the mix of secure and normal mode is not supported, i.e. it's
assumed that the processor is always in secure mode.
