1003: all Cargo.toml: Add license to all crate Cargo.toml files r=lulf a=chrysn
This sets the license to "MIT OR Apache-2.0" in a machine readable form on all crates, as it was already in human readable form in the README.md file, and reaffirmed in #1002.
(The statements on all the individual examples might not be strictly essential for the `cargo deny` use case as they are leaf crates, but other tools might use that information).

1000: Forgot to add space function to immediate publisher r=lulf a=diondokter
Title says it all really. This function was added to the normal publisher, so now also to the immediate publisher

996: Add required info to embassy-sync package r=Dirbaio a=lulf
Updates the README.md based on embassy-futures structure.
Co-authored-by: Ulf Lilleengen <lulf@redhat.com>
Assert "tx_empty" interrupt a little early so there's time to wake up
and start refilling the fifo before it drains. This avoids stalling the
i2c bus if the tx fifo completely drains.
993: rp i2c: blocking example r=Dirbaio a=jsgf
i2c example talking to mcp23017 i2c gpio expander.
Co-authored-by: Jeremy Fitzhardinge <jeremy@goop.org>
Simple example exercising an mcp23017 GPIO expander, configured on
RP2040 GPIOs 14+15 (i2c1) with 8 inputs and 8 outputs. Input bit 0
controls whether to display a mcp23017 register dump.
This is an interrupt-driven async i2c master implementation. It makes as
best use of the RP2040's i2c block's fifos as possible to minimize
interrupts.
It implements embedded_hal_async::i2c for easy interop.
WIP async impl
992: (embassy-stm32): remove flash lock/unlock public API from stm32 flash r=lulf a=MathiasKoch
Instead, perform the unlocking and locking automatically on erase and write operations.
This makes the `embedded-storage` abstraction actually useable in libraries, while still keeping the flash peripheral locked the majority of the time.

990: Small pubsub improvements r=Dirbaio a=diondokter
- Futures in pub & sub are now awaited instead of returned
- Added functions for reading how many messages are available
This helps people get better compiler diagnostics. For example, I forgot to call await on a future and the compiler didn't complain.
This also helps with making some decisions based on the state of the channels.
