Scott Worley 53e17c4c22 drivers: spi: microchip: Add SPI driver for MEC5 HAL quad SPI
SPI driver for Microchip MEC5 HAL based QSPI controller. QSPI
hardware supports full duplex, dual, and quad operation. MEC5
QSPI controller also includes three local DMA channels per
direction to off load firmware. The driver API supports full
or half-duplex. Due to QSPI hardware not supporting one wire
half-duplex, this driver supports full-duplex only. QSPI hardware
design requires it to control chip select and current hardware
supports up to two chip selects. Zephyr's SPI DT macros store the
child SPI device's reg properity as the "slave" member of the SPI
configuration structure. The driver uses the "slave" value as the
chip select. Additional timing settings specific to SPI flash devices
are in a new SPI device YAM file: "microchip,mec5-qspi-device.yaml"
which includes the standard "spi-device.yaml". If the new YAML is not
used, the QSPI controller will use default timing values for chip
select and I/O line taps.

The Zephyr Project is a scalable real-time operating system (RTOS) supporting
multiple hardware architectures, optimized for resource constrained devices,
and built with security in mind.

The Zephyr OS is based on a small-footprint kernel designed for use on
resource-constrained systems: from simple embedded environmental sensors and
LED wearables to sophisticated smart watches and IoT wireless gateways.

The Zephyr kernel supports multiple architectures, including ARM (Cortex-A,
Cortex-R, Cortex-M), Intel x86, ARC, Tensilica Xtensa, and RISC-V,
SPARC, MIPS, and a large number of `supported boards`_.
