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.
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.

This separation allows to interact with the watchdog from OS code,
for example initiating the watchdog very early on boot. Moreover,
these changes make the lower-half driver support an already running
watchdog, which may happen if there's a bootloader which already
started it.
Follow the POSIX description.
SIGTSTP should be sent when the Ctrl-Z characters is encountered, not SIGSTP.
Testing:
Built with hifive1-revb:nsh (CONFIG_SERIAL_TERMIOS=y, CONFIG_SIG_DEFAULT=y and CONFIG_TTY_SIGTSTP=y)
the mkspk tool will automaticaly be built if CONFIG_CXD56_BINARY
is set.
Test:
nuttx.spk was succesfully generated
