495b8b739a Change GPIO inherent methods back to &self.
With the embedded-hal rc3 update I changed them to require `&mut self`, but
in retrospect I think `&self` is better, for extra flexibility.

This PR reverts the changes from the rc3 update to inherent methods.

71c4e7e4d2 Fix timing on RP2040 pio_ws2812.rs example
The example spins too fast so it doesn't appear to change;
it's delaying for microseconds instead of milliseconds.
This commit slows it down and adds a comment noting the pin
mapping for the Adafruit feather rp2040+RFM95 LoRA module,
which has its Neopixel on pin 4 instead of 16.

a6b8f3d994 rp: add single-channel dma from adc
with uniform treatment of adc inputs it's easy enough to add a new
sampling method. dma sampling only supports one channel at the moment,
though round-robin sampling would be a simple extension (probably a new
trait that's implemented for Channel and &[Channel]). continuous dma as
proposed in #1608 also isn't done here, we'd expect that to be a
compound dma::Channel that internally splits a buffer in half and
dispatches callbacks or something like that.

b166ed6b78 rp: generalize adc inputs from pins to channels
this lets us treat pins and the temperature sensor uniformly using the

combinatorial explosion of methods and types needed to handle them all.

cbc8871a0b rp: relocate programs implicitly during load
this removed the RelocatedProgram construction step from pio uses.
there's not all that much to be said for the extra step because the
origin can be set on the input program itself, and the remaining
information exposed by RelocatedProgram can be exposed from
LoadedProgram instead (even though it's already available on the pio_asm
programs, albeit perhaps less convenient). we do lose access to the
relocated instruction iterator, but we also cannot think of anything
this iterator would actually be useful for outside of program loading.

972cdd4265 rp/adc: rewrite the module
- don't require an irq binding for blocking-only adc
- abstract adc pins into an AnyPin like interface, erasing the actual
  peripheral type at runtime.
- add pull-up/pull-down functions for adc pins
- add a test (mostly a copy of the example, to be honest)
- configure adc pads according to datasheet
- report conversion errors (although they seem exceedingly rare?)
- drop embedded-hal interfaces. embedded-hal channels can do neither
  AnyPin nor pullup/pulldown without encoding both into the type

f97b591831 rp/clocks: don't expose unstable pac items
exposing pac items kind of undermines the unstable-pac feature. directly
exposing register structure is also pretty inconvenient since the clock
switching code takes care of the src/aux difference in behavior, so a
user needn't really be forced to write down decomposed register values.

1458: rp: remove take!, add bind_interrupts! r=Dirbaio a=pennae

both of the uart interrupts now check a flag that only the dma rx path ever sets (and now unsets again on drop) to return early if it's not as they expect. this is ... not our preferred solution, but if bind_interrupts *must* allow mutiple handlers to be specified then this is the only way we can think of that doesn't break uarts.

It was intended to allow changing baudrate on shared spi/i2c. There's no
advantage in using it for PWM or PIO, and makes it less usable because you have to
have `embassy-embedded-hal` as a dep to use it.

1435: Added example for multi priority executors rp2040 r=Dirbaio a=fakusb

I added an example for multiple priorities of tasks on rp2040 by adjusting [examples/nrf52840/src/bin/multiprio.rs](https://github.com/embassy-rs/embassy/blob/master/examples/nrf52840/src/bin/multiprio.rs) .

This needs https://github.com/embassy-rs/rp-pac/pull/2 , and this commit also adds the 6 new interrupt handlers for software interrupts to embassy-rs.

We might need to change the git path for rp-pac in [embassy-rp/Cargo.toml](https://github.com/embassy-rs/embassy/compare/master...fakusb:rp2040-multiprio-executor?expand=1#diff-47463ea358745927ecdb686f52feab816fde5d402a9628a136c116f34a802ab0)

Closes #1413

b38d496d51 rp/pio: allow wrap-around program loading
execution wraps around after the end of instruction memory and wrapping
works with this, so we may as well allow program loading across this
boundary. could be useful for reusing chunks of instruction memory.

the many individual sets aren't very efficient, and almost no checks
were done to ensure that the configuration written to the hardware was
actually valid. this adresses both of these.

41ec4170a5 rp/pio: add load_program, use_program
programs contain information we could pull from them directly and use to
validate other configuration of the state machine instead of asking the
user to pull them out and hand them to us bit by bit. unfortunately
programs do not specify how many in or out bits they use, so we can only
handle side-set and wrapping jumps like this. it's still something though.

c44c108db5 rp/pio: wrap sm rx, tx in structs and allow splitting
this *finally* allows sound implementions of bidirectional transfers
without blocking. the futures previously allowed only a single direction
to be active at any given time, and the dma transfers didn't take a
mutable reference and were thus unsound.

909a5fe2e5 rp/pio: split irqs from state machines
we can only have one active waiter for any given irq at any given time.
allowing waits for irqs on state machines bypasses this limitation and
causes lost events for all but the latest waiter for a given irq.
splitting this out also allows us to signal from state machines to other
parts of the application without monopolizing state machine access for
the irq wait, as would be necessary to make irq waiting sound.

486fe9e59d rp/pio: remove PioStateMachineInstance
move all methods into PioStateMachine instead. the huge trait wasn't
object-safe and thus didn't have any benefits whatsoever except for
making it *slightly* easier to write bounds for passing around state
machines. that would be much better solved with generics-less instances.

8839f3f62a rp/pio: PioInstance::split -> Pio::new
not requiring a PioInstance for splitting lets us split from a
PeripheralRef or borrowed PIO as well, mirroring every other peripheral
in embassy_rp. pio pins still have to be constructed from owned pin
instances for now.

3229b5e809 rp/pio: remove PioPeripheral
merge into PioInstance instead. PioPeripheral was mostly a wrapper

PioInstanceBase<N> types where PIO{N} could've been used instead.

peripheral, and this example exercises many pio features that we don't
have good examples for yet.

1414: rp: report errors from buffered and dma uart receives r=Dirbaio a=pennae

neither of these reported errors so far, which is not ideal. add error reporting to both of them that matches the blocking error reporting as closely as is feasible, even allowing partial receives from buffered uarts before errors are reported where they would have been by the blocking code. dma transfers don't do this, if an errors applies to any byte in a transfer the entire transfer is nuked (though we probably could report how many bytes have been transferred).

f4ade6af8b rp/pio: write instr memory only from common
instruction memory is a shared resource. writing it only from PioCommon
clarifies this, and perhaps makes it more obvious that multiple state
machines can share the same instructions.

this also allows *freeing* of instruction memory to reprogram the
system, although this interface is not entirely safe yet. it's safe in
the sense rusts understands things, but state machines may misbehave if
their instruction memory is freed and rewritten while they are running.
fixing this is out of scope for now since it requires some larger
changes to how state machines are handled. the interface provided
currently is already unsafe in that it lets people execute instruction
memory that has never been written, so this isn't much of a drawback for now.

58e727d3b9 rp/pio: move non-sm-specific methods to PioCommon
pin and irq operations affect the entire pio block. with pins this is
not very problematic since pins themselves are resources, but irqs are
not treated like that and can thus interfere across state machines. the
ability to wait for an irq on a state machine is kept to make
synchronization with user code easier, and since we can't inspect loaded
programs at build time we wouldn't gain much from disallowing waits from
state machines anyway.
