imxrt-hal 0.5.9

• Fixes a LPSPI word unpacking bug: #176.
• Adds a Debug implementation for TempMon: #177.

imxrt-hal 0.5.8

Includes #172 and #173.

imxrt-hal 0.5.7

Add PLL7 for 1060 MCUs.

imxrt-hal 0.5.6

• Add LPSPI low-level clock configuration APIs.
• Add LPSPI set_peripheral_enable to configure the driver as a SPI peripheral.

When the LPI2C driver concludes a transaction, it ensures that the controller
is idle before returning.

imxrt-hal 0.5.5

Add embedded-hal 1 implementations for the following drivers:

• GPIO
• LPUART
• LPI2C

Introduce LPSPI improvements:

• Add additional checks for LPSPI frame sizes.
• Rework LPSPI clock settings, initialization, and disable.
• Add flush() method.
• Add soft_reset() method.
• Allow users to change the mode while enabled. Deprecate the corresponding
  method on the Disabled helper.
• Allow users to change the watermark while enabled. Deprecate the corresponding
  method on the Disabled helper.

Change how the LPSPI driver manages the FIFOs. As a result of this change, the
driver never returns the Busy or NoData errors through the embedded-hal
interfaces. Instead of returning Busy, the driver blocks until there's space in
the FIFO. If the caller provides an empty buffer, then the result is OK.

The LPSPI embedded-hal (0.2) implementations will implicitly flush after blocking
I/O. Users can rely on this behavior to synchronize external components.

imxrt-hal v0.5.4

Add FlexIO CCM APIs for 1000 targets.

imxrt-hal v0.5.3

Add FlexIO clock gates.

imxrt-hal 0.5.2

Fix a bug in the LPSPI driver that prevented transfers from reading data back into the caller's buffer. The LPSPI transfer now waits for all data before returning to the caller.

Add LPSPI API to configure the sample point.

imxrt-hal 0.5.1

Add support for i.MX RT 1020 processors. Enable support with the "imxrt1020"
imxrt-hal feature, and separately select your imxrt-ral feature.

Deprecate the clko2::Selection::TracClk item. Prefer the correctly-spelled
variant, clko2::Selection::TraceClk.

Deprecate the following items in the timer module:

• timer::BlockingPitChan and constructor from_pit_channel.
• timer::RawCountDownPitChanand constructor from_pit_channel.

The type names differ from *PitChain by one letter. Prefer the spellings
without *Chan and *_channel.

---

Add support for executing in-repo examples on i.MX RT 1060 EVKs.

Release 0.4.5

Added

You can now configure GPIO inputs to trigger interrupts. See the GPIO
documentation for the new API.

Fixed

The TRNG signals a rand_core custom error code.
