arch/arm/src/stm32/hardware/stm32_dmamux.h,
arch/arm/src/stm32/hardware/stm32g47xxx_dmamux.h:
* New files, based on STM32G474RE reference manual, RM0440 Rev 4.
Used reference manual for STM32G071CB. The F0 and L0 families do not
appear to have a DMAMUX.
arch/arm/src/stm32f0l0g0/hardware/stm32_dmamux.h:
* Remove all mentions of DMAMUX12 from comments. This family has
at most DMAMUX1 only.
* Add missing defines DMAMUX_CCR_SPOL_NONE,
DMAMUX_CCR_SPOL_RISING, DMAMUX_CCR_SPOL_FALLING, and
DMAMUX_CCR_SPOL_BOTH.
* DMAMUX_CCR_SYNCID_SHIFT: Fix comment. Was "Bits 24-26" (3 bits)
but datasheet shows bits 24-28 (5 bits).
* DMAMUX_CCR_SYNCID_MASK: Fix mask. Was 0x7 (3 bits) but datasheet
shows (5 bits) 0x1f.
* DMAMUX1_CSR_SOF(x): Add parenthesis around macro parameter
expansion.
* DMAMUX1_CFR_SOF(x): Rename to DMAMUX1_CFR_CSOF(x) for
consistency with datasheet and add parenthesis around macro
parameter expansion.

DMAMUX_RGCR_GPOL_RISING, DMAMUX_RGCR_GPOL_FALLING, and
DMAMUX_RGCR_GPOL_BOTH.
* DMAMUX_RGCR_GNBREQ_SHIFT: Fix incorrect value. Was 17 (collision
with DMAMUX_RGCR_GPOL_SHIFT) but datasheet and comment both show
this bitfield at bits 19-23.
* DMAMUX_RGCR_GNBREQL_MASK: Fix incorrect mask. Was 0x7 (3 bits)
but datasheet shows 5 bits (0x1f).

arch/arm/src/stm32/hardware/stm32_spi.h:
* Avoid numerous ifdef on STM32 part numbers and make the
different variations of SPI peripheral features more
self-documenting: based on STM32_HAVE_IP_SPI_V* defines
from chip.h, define some or all of HAVE_SPI_I2S,
HAVE_SPI_TI_MODE, HAVE_SPI_ARB_DATA_SIZE, HAVE_SPI_FIFOS,
HAVE_SPI_NSSP, HAVE_SPI_I2S_ASTRT, and make decisions on
which registers and bitfields to define based on them.
* Define registers and bitfields for STM32_HAVE_IP_SPI_V4,
currently used only for STM32G47XX family MCUs, including
SPI_CR1_CRCL, SPI_CR2_NSSP, SPI_CR2_FRXTH, SPI_CR2_LDMARX,
SPI_CR2_LDMATX, SPI_CR2_DS_SHIFT/SPI_CR2_DS_MASK,

(xx << SPI_I2SCFGR_I2SSTD_SHIFT). Corrected this to
(0 << SPI_I2SCFGR_I2SSTD_SHIFT).
* SPI_I2SCFGR_I2SSTD_MSB: Was defined incorrectly as
(0 << SPI_I2SCFGR_I2SSTD_SHIFT). Corrected this to

This change improves upon current support for pin interrupts. Before,
a pin interrupt was handled (with nrf52_gpiote_setevent) using one
of the eight available GPIOTE channels. Moreover, it didn't event let
the user specify which channel to use (simply tried to get a free one).
Also, it was buggy since it did not consider unsetting the callback.
Besides GPIOTE channels, there is another way to deal with pin interrupts.
The GPIO peripheral is capable of generating a PORT event
(for the whole GPIO port) depending on the pin SENSE configuration
(HIGH or LOW, or NONE) and GPIO DETECTMODE register
(latching or non-latching).
This change then renames nrf52_gpiote_setevent into nrf52_gpiote_set_ch_event,
maintaining functionality of original function, but now allows specifying
channel (and correctly handles unsetting the callback). Then, a
new nrf52_gpiote_set_pin_event is added, which allows to set a callback
for a given pin. During initialization, interrupt for the PORT event is
enabled and handled in such way that for each pin whose corresponding
bit in LATCH register (indicates the result of pin SENSEing) the
callback for this pin will be invoked. This mechanism means that
every pin can get an ISR. It also avoids using GPIOTE channels for this
purpose which carry higher current consumption.
This new per-pin callback mechanism has some added memory requirement
so it can be disabled and its default is dependant on DEFAULT_SMALL.
When disabled, a callback for the PORT event can be set directly
with nrf52_gpiote_set_port_event
There was only one use of nrf52_gpio_setevent() which was migrated
into nrf52_gpio_set_ch_event() passing channel zero.

1. function "stop" should really stop repeat timer
2. delete timer really in rt-timer task to avoid resource being broken
3. timer triggers when stopping/deleting it and skip it in ISR
When HAVE_HSI_CONTROL, adc_reset_hsi_disable() calls adc_reset()
followed by adc_shutdown() and this combination is called before
adc_setup() by upper level ADC driver. Without this patch,
priv->initialized wraps from 0 to 255 in this case.

In the current compilation environment, the recursive assignment(=) for compile
flags will be delayed until every file is actually need to be compile.
For example:
--------------------------------------------------------------------------------
arch/arm/src/Makefile:
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)chip}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)common}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(ARCH_SRCDIR)$(DELIM)$(ARCH_SUBDIR)}
INCLUDES += ${shell $(INCDIR) "$(CC)" $(TOPDIR)$(DELIM)sched}
CPPFLAGS += $(INCLUDES) $(EXTRAFLAGS)
CFLAGS += $(INCLUDES) $(EXTRAFLAGS)
CXXFLAGS += $(INCLUDES) $(EXTRAFLAGS)
AFLAGS += $(INCLUDES) $(EXTRAFLAGS)
--------------------------------------------------------------------------------
All compilation options will be included recursively,
which will be delayed until the compilation options are actually used:
tools/Config.mk:
--------------------------------------------------------------------------------
define COMPILE
@echo "CC: $1"
$(Q) $(CC) -c $(CFLAGS) $($(strip $1)_CFLAGS) $1 -o $2
endef
--------------------------------------------------------------------------------
All compile flags to be reexecuted $(INCDIR) as long as one file needs to be compiled,
but in fact, the compilation options have not changed in the current directory.
So the we recommand to change the syntax of assignment
From
Recursive (=)
To
Simple (:=)
In this way, we can ensure that all compilation options are expanded only once and reducing repeated works.
