The `need_switch` flag was not initialized in `event_post()`. Since it is
a local variable, it could contain a random non-zero value, leading to
incorrect behavior.
In addition, this patch also fixes an issue where the event clearing
operation in `event_post()` was not performed correctly.

The Nuttx MSS CAN driver has an exclusive interface to the integrated MSS CAN peripheral residing in Polarfire SoC FPGAs. There are two CAN block 0 and 1 that can be configured for use. In normal mode (non AMP), CAN0 and CAN1 block base register addresses are 0x2010C000UL and 0x2010D000UL.

The DEBUGASSERT is wrong in two cases;
1) In SIM, which does sim_timer_update from the idle task, and the sim timer runs on signals
2) If signal is dispatched from within an interrupt
In these cases, if there are not available items for pending signals, return
the nxsig_tcbdispatch with -EAGAIN instead of asserting.

Remove the nxevent_tickwait_wait() description from events.rst,
since this API was removed during the event module refactoring.
Signed-off-by: Chengdong Wang <wangchengdong@lixiang.com>
The current event implementation relies on a dedicated wait object,
which introduces several issues:
1. Increases memory usage
2. Complicates the event logic
3. Makes the API design less clean, as it requires a separate
nxevent_tickwait_wait() function
This patch removes the event’s dependency on the wait object
and eliminates the nxevent_tickwait_wait() API accordingly.
BREAKING CHANGE: this commit removed the nxevent_tickwait_wait function
so the related docs should be updated accordingly

The current event implementation uses semaphores for wait and post
operations. Since semaphores are relatively heavy-weight and intended
for resource-based synchronization, this is suboptimal.
So this patch replaced the semaphore-based mechanism with direct
scheduler operations to improve performance and reduce memory footprint.
This patch also introduce a new task state TSTATE_WAIT_EVENT to indicate
the task is waiting for a event.
BREAKING CHANGE: This commit introduced a new task state TSTATE_WAIT_EVENT
so apps/nshlib/, procfs/ and tools/pynuttx/nxgdb/ are needed to be updated accordingly.

The adc_dmaconvcallback routine was far too slow and inefficient. This was not caught until recently when I was testing faster sample rates. When in circular mode for the adc (dma and constant conversions), the adc_dmaconvcallback function would overwhelm the OS and lock it up. I looked into this and did a lot of testing. First I tried minimally improving the dma callback by removing the % operator from the algorithm, this was slow and inefficient. I also tried increasing the batch size considerably as well as the fifo size. This helped but the OS would still lockup with the fastest sample rate (5 Msps). au_receive_batch was the solution. In order to use this, I needed to change the dmabuffer to be of type uint32_t to match the data pointer in au_receive_batch. I also needed to create a channel buffer, which is initialized once in adc_setup. stm32_gpdma_cfg_s->tr1 needed to be updated for the uint32_t dmabuffer. Once I made changes to use au_receive_batch, I could reliably use the fastest sample rate without locking up the OS. Calling au_receive for every single conversion in a batch is far less efficient than calling au_receive_batch. I also snuck in some changes for the ADC watchdog defines and guards. These were fixes that were tested while testing these changes.

This initial implementation sets up support for the EMMC interfaces on
the BCM2711. Only EMMC2 is tested since it is the interface of interest
(connects to uSD card). MMCSD communication is functional and the boot
partition of the SD card can be mounted and interacted with.
Insertion/removal interrupts do not fire after initial boot, and
sdstress fails with any byte size larger than 1023. 32GB card works
perfectly, while 64GB card exhibits strange behaviour when interacting
with VFAT filesystem.

nxsig_wait_irq() is always invoked within an existing critical section,
and the task state is already verified, similar to nxsem_wait_irq().

The above function was removed in d8cb7759.
