Swift Tian	43e23cf9f2	drivers: mspi: Add Ambiq apollo3p mspi controller ... The Ambiq MSPI controller is implemented using the MSPI bus API. The hardware supports up to 48MHz octal SDR with XIP, scrambling and hardware command queue features. Signed-off-by: Swift Tian <swift.tian@ambiq.com>	2024-06-14 21:07:00 -04:00
Swift Tian	f5554ca762	emul: mspi: Add the mspi controller emulator ... Add bus emulator support for MSPI and the MSPI controller emulator. The mspi_emul.c not only serves as an emulator but also provides an example implementation of the MSPI API. It does not actually do anything other than validating parameters and forwarding transceive request back to the device driver emulators.

Swift Tian	8a2bf58826	drivers: mspi: Add the new MSPI API ... The MSPI(multi-bit SPI) is provided as a generic API to accommodate advanced SPI peripherals and devices that typically require command, address and data phases, and multiple signal lines during these phases. While the API supports advanced features such as XIP eXecute In Place and scrambling, it is also compatible with generic SPI.
