Kumar Gala 83d8ffb2a0 spi: mcux: Rename spi driver to DSPI to match naming convention
In prep for supporting the older KL2x SoCs that use a different SPI
block, rename the current SPI driver to DSPI to match what the MCUX HAL
defines it as.

Maureen Helm 8769cd585e spi: k64: Remove the k64 spi driver
Now that we have a more generic mcux spi driver that can be used across
multiple Kinetis SoCs, remove the specific k64 spi driver.

Maureen Helm d138a4fad1 spi: Introduce new mcux shim driver
Adds a shim layer around the mcux dspi driver to adapt it to the Zephyr
spi interface. Unlike the existing k64 spi driver, this driver can be
used for other Kinetis SoCs that contain the dspi module.

Baohong Liu 35633586f2 spi: quark se: Add QMSI 1.1-based SPI shim driver
Add SPI sub-driver for sensor system.

Use SPI irq number definitions already in Zephyr header file.

Jeff Blais 995a9ba72a arm: K64 SPI module driver
Support for Freescale/NXP K64 SPI modules, limited to:

- Master mode
- A single active set of clock and transfer attributes (CTAR0), which
includes non-adjustable delay parameters
- Tx FIFO fill and Rx FIFO drain interrupt handling
- Standard, continuous select and continuous SCK SPI transfer formats

Also, divide-by-zero code generation in this driver is prevented.
The 'volatile' attribute is added to some of the variables in the baud
rate and delay calculation functions of the K64 SPI driver in order to
prevent bad code generation by gcc toolchains for ARM seen when an
optimization setting above -O0 is used.
Specifically, a register is loaded with the constant 0 and is used as
the divisor in a following divide instruction, resulting in a
divide-by-zero exception.
This issue has been seen with gcc versions 4.8.1 (the VxWorks toolchain)
and 5.2.0 (the Zephyr SDK toolchain).

Vinicius Costa Gomes 40f8914376 spi: Add QMSI-based implementation
This driver uses the QMSI library and mostly translates calls from the
Zephyr API to QMSI ones.

This driver conflicts with the native driver implemenation. In order to
enable it, you must set:
CONFIG_QMSI_DRIVERS=y
CONFIG_QMSI_INSTALL_PATH="PATH_TO_QMSI"
CONFIG_SPI_QMSI=y
CONFIG_SPI_QMSI_PORT_0=y
CONFIG_SPI_QMSI_PORT_1=y

Missing:
 - Support for using a GPIO pin as Chip Select;

Andrew Boie d9cfbd5a61 interrupts: new static IRQ API
The interrupt API has been redesigned:

- irq_connect() for dynamic interrupts renamed to irq_connect_dynamic().
  It will be used in situations where the new static irq_connect()
  won't work, i.e. the value of arguments can't be computed at build time
- a new API for static interrupts replaces irq_connect(). it is used
  exactly the same way as its dynamic counterpart. The old static irq
  macros will be removed
- Separate stub assembly files are no longer needed as the stubs are now
  generated inline with irq_connect()

ReST documentation updated for the changed API. Some detail about the
IDT in ROM added, and an oblique reference to the internal-only
_irq_handler_set() API removed; we don't talk about internal APIs in
the official documentation.
