- Add retry timeout to prevent inifinite loop
- Change the register operation of power control
- Add exclusive control by semaphore into some functions
- Add short delay until power control is reflected
This commit enhances ADC and PWM drivers with option to trigger ADC
conversion with events generated by PWM comparison units.
The generation of PWM events is handled by comparison units set up from
Kconfig option SAMV7_PWMx_TRIGn. ADC triggering from PWM can be selected
by AFECn_PWMTRIG option.

SAMv7 PWM driver supports complementary PWM output if both pins (H and L)
are defined and configured. This commit adds a configuration option to
configure the complementary L pin.
The pin definition has to be provided by board level support.

Summary:
- I noticed that there are two kinds of descriptors for imxrt_enet.c
- The first one is the legacy descriptor and its size is 8bytes.
- The second one is the enhanced descriptor and its size is 32bytes.
- In both cases, we can not use a descriptor chain like stm32.
- Considering cache line alignment, the second one is perfect because
one descriptor fits the Cortex-M7 cache line which would fix networking
stability issues in d-cache write-back mode.
Impact:
- imxrt ethernet in d-cache write-back mode
Testing:
- Tested with ixmrt1060-evk:netnsh_dcache_wb (will be added later)

Summary:
- I noticed that CONFIG_IMXRT_ENET_ENHANCEDBD is not correctly
used though it is defined in Kconfig.
- This commit fixes this issue.
Impact:
- None
Testing:
- Tested with imxrt1060-evk:netnsh_dcache_wb (will be added later)

This reverts commit 62c15c03d3.
Fix warning: the choice symbol STM32_FLASH_CONFIG_G (defined at arch/arm/src/stm32/Kconfig:1275) is selected by the following symbols, but select/imply has no effect on choice symbols
- ARCH_CHIP_STM32F412ZG (defined at arch/arm/src/stm32/Kconfig:1014)
Generic drivers shoud not use architecture related config options like
CONFIG_SAMV7_PWM. This commit adds PWM pin overwrite under generic
configuration option CONFIG_PWM_OVERWRITE.
Now the overwrite can be used on other architectures as well or can be
completely disabled for SAMv7.

Commit d07792a caused a build error in sam_mcan.c file. This commit fixes
the build. The file now succesfully compiles and CAN works.

When I checked how this register was set I discovered that 128 was not
accepted by the H7 but 64 was ok. Looking at the STM32Cube's HAL it
seems to be only 64 words long, however, the reference manual claims
otherwise.
I have opened a discussion on the ST community forum
https://community.st.com/s/question/0D73W000001nzqFSAQ
but unfortunately not received an answer yet.
In the meantime, I think, we should update this to what I found to be
working though.

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.

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.

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.
* arch/arm/src/tiva/common/tiva_serial.c:
(up_ioctl): PR #8406 (commit 1edec0aaa1) added support for
configuring the serial port's CTS/RTS flow control at runtime using
termios when built with CONFIG_SERIAL_TERMIOS and either or both of
CONFIG_SERIAL_OFLOWCONTROL and CONFIG_SERIAL_IFLOWCONTROL. However,
a runtime sanity check left over from before prevented this from
working: When processing ioctl TCSETS, we would return -EINVAL if
one or both of CCTS_OFLOW and CRTS_IFLOW were requested, which was
not deserved if the requested features were in fact supported.
Fixing the sanity check so it depends on features actually
configured.
The function is not relevant any longer, remove it. Also remove
save_addrenv_t, the parameter taken by up_addrenv_restore.
Implement addrenv_select() / addrenv_restore() to handle the temporary
instantiation of address environments, e.g. when a process is being
created.
Detach the address environment handling from the group structure to the
tcb. This is preparation to fix rare cases where the system (MMU) is left
without a valid page directory, e.g. when a process exits.
