Current implementation supports the trigger generation only from timer
capture on period value. This is sufficient for PWM synchronization but
may not be enough for other purposes as ADC triggering for example.
This change adds an option to generate the trigger based on a duty
cycle value.

with the test of sim:lua ,I have fixed some bug of error output
1.input: " " and error output string is "NULL"
2.input: "1.2e+", error output string is "NULL"
3.input: "." error output string is "NULL"
Summary:
- Fix knsh/defconfig to work with pyOCD
- Fix kernel-space.ld to boot
- Fix memory.ld for CONFIG_BUILD_PROTECTED=y
Impact:
- CONFIB_BUILD_PROTECTED=y only
Testing:
- Tested with imxrt1060-evk

The function call dac_txdone(&g_dac1dev) was not contained in ifdef
section. This was cousing compilation error if only DAC1 was configured
as the structure g_dac1dev is defined only if DAC0 is used.
This commit fixes the error and ensures the function is called only if
corresponding DAC is configured.

There is an issue where the wrong process exit code is given to the parent
when a process exits. This happens when the process has pthreads running
user code i.e. not within a cancel point / system call.
Why does this happen ?
When exit() is called, the following steps are done:
- group_kill_children(), which tells the children to die via pthread_cancel()
Then, one of two things can happen:
1. if the child is in a cancel point, it gets scheduled to allow it to leave
the cancel point and gets destroyed immediately
2. if the child is not in a cancel point, a "cancel pending" flag is set and
the child will die when the next cancel point is encountered
So what is the problem here?
The last thread alive dispatches SIGCHLD to the parent, which carries the
process's exit code. The group head has the only meaningful exit code and
this is what should be passed. However, in the second case, the group head
exits before the child, taking the process exit code to its grave. The child
that was alive will exit next and will pass its "status" to the parent process,
but this status is not the correct value to pass.
This commit fixes the issue by passing the group head's exit code ALWAYS to
the parent process.
First decoupling changes related to CMAKE
BINDIR/APPSBINDIR:
Output path of Kconfig which dynamically generated by NuttX Kernel/Apps
This option is consistent with the TOPDIR/APPSDIR by default, and will
be changed when out-of-tree compilation is supported

Previously, it was impossible to build for PIC32MZ architecture with
CONFIG_SERIAL_TERMIOS because it introduced compiler errors in the
lower half driver.
Fixing the compiler errors and adding an implementation of the
TIOCSERGSTRUCT, TCGETS, and TCSETS ioctl calls.
* arch/mips/src/pic32mz/pic32mz_serial.c
(): Include nuttx/fs/ioctl.h, needed for the TIOCSERGSTRUCT, TCGETS,
and TCSETS defines.
(up_ioctl): Fix compile breakage. Implement TIOCSERGSTRUCT. Make
TCGETS return data bits, parity, and stop bits. Make TCSETS apply
changes to data bits, parity, and stop bits.
In the lower half UART driver for Tiva architecture (TM4C12x), adding
the TIOCxBRK ioctl calls, which allow an application to transmit a BSD
compatible line BREAK. TIOCSBRK starts the BREAK and TIOCCBRK ends it.
This architecture supports BSD-style BREAK in hardware. We write to
the BRK bit (bit 0) of the UART Line Control register (UARTLCRH) to
start the BREAK, which begins after the UART finishes shifting out the
current character in progress, if any, including its stop bit(s), and
continues indefinitely until we write to the BRK bit again to stop the
BREAK.
* arch/arm/src/tiva/Kconfig
(config TIVA_UART_BREAKS): New. Appears as CONFIG_TIVA_UART_BREAKS
in code.
* arch/arm/src/tiva/common/tiva_serial.c
(struct up_dev_s): Add new field 'brk' to indicate line break in
progress when built with CONFIG_TIVA_UART_BREAKS.
(up_ioctl): Add cases for TIOCSBRK to turn BSD-compatible break on
unconditionally and TIOCCBRK to turn break off unconditionally.
(up_txint): Block enabling TX interrupt if line break in progress.
This is similar to the STM32F7 implementation.
SOCK_CTRL is added to provide special control over network drivers
and daemons. Currently, SOCK_DGRAM and SOCK_STREAM perform this control,
but these use socket resources. In the case of usersocket in particular,
this is a waste of the device's limited socket resources.
