4618b79b22 rp/pio: seal PioInstance, SmInstance
seems prudent to hide access to the internals.

db16b6ff3f rp/pio: don't call dma::init so much
this is already done during platform init. it wasn't even sound in the
original implementation because futures would meddle with the nvic in
critical sections, while another (interrupt) executor could meddle with
the nvic without critical sections here. it is only accidentally sound
now and only if irq1 of both pios isn't used by user code. luckily the
worst we can expect to happen is interrupt priorities being set wrong,
but wrong is wrong is wrong.

a9074fd09b rp/pio: enable pio interrupts only once
since we never actually *disable* these interrupts for any length of
time we can simply enable them globally. we also initialize all pio
interrupt flags to not cause system interrupts since state machine
irqa are not necessarily meant to cause a system interrupt when set. the
fifo interrupts are sticky and can likewise only be cleared inside the
handler by disabling them.

f2469776f4 rp/pio: use atomic accesses, not critical sections
atomic accesses are not only faster but also can't conflict with other
critical sections.

a10850a6da rp/pio: handle all pio irqs in one handler
dma does this too, also with 12 bits to check. this decreases code size
significantly (increasing speed when the cache is cold), frees up an
interrupt handler, and avoids read-modify-write cycles (which makes each
processed flag cheaper). due to more iterations per handler invocation
the actual runtime of the handler body remains roughly the
same (slightly faster at O2, slightly slower at Oz).

notably wakers are now kept in one large array indexed by the irq
register bit number instead of three different arrays, this allows for
machine code-level optimizations of waker lookups.

1405: add IPCC peripheral for stm32wb r=xoviat a=OueslatiGhaith

Hello again,

This pull request is related to #1397 and #1401, inspired by #24, and was tested on an stm32wb55rg.

This pull request aims to add the IPCC peripheral for stm32wb microcontrollers.
I am debating whether this should be included in the public API, since the IPCC peripheral would be typically managed by the TL Mailbox, not by the app directly.

1412: stm32/uart: abort on error r=Dirbaio a=xoviat

This PR aborts the DMA transfer in the event of a UART error. Otherwise, the transfer will never complete, and an error will not be returned.

1403: Bump versions preparing for -macros and -executor release r=lulf a=lulf

I'd like to propose a new release of embassy-macros and embassy-executor, as there is a challenge with some of the features changing since 0.1.1 when using libraries that depend on 0.1.1 with applications that patch to use git versions.

1406: rp: DMA behaviour during flash operations r=Dirbaio a=kalkyl

This PR changes the old behaviour during flash operations where all DMA transfers were paused during the flash operation.
The new approach is to wait for any DMA operating in flash region to finish and let RAM transfers continue.

054ca17f66 Switch from probe-run to probe-rs-cli.
- probe-run screwed up the last release 2 weeks ago and it's still not fixed (issue 391). Doesn't look well maintained.
- Even when it's not broken, it lags behind probe-rs-cli in new chips support because it's slow in updating probe-rs.

1392: embassy-rp : Fix for division intrinsics clashing with rp2040-hal r=Dirbaio a=peterkrull

Commit [7a682ec](7a682ec02a (diff-f121955242a67342004444b26214e5d1d591c3182dcd0fedf4329ad472cd1200)) may break compilation if also using `rp2040-hal`. It seems that the rp2040-hal does have a feature flag for [disabling intrinsics](2c9921cdc5/rp2040-hal/src/sio.rs (L323)), but I still cannot seem to compile with that enabled. Adding these flags fixes it for me.
