Subject: [PATCH v1 0/3] Add support for Microchip CoreSPI Controller

This patch series adds support for the Microchip FPGA CoreSPI "soft" IP 
and documents its device tree bindings.

As preparation, the existing Microchip SPI driver is renamed to clearly
indicate that it supports only the Microchip PolarFire SoC "hard" controller.
Although it was originally named with the expectation that it might also
cover the FPGA CoreSPI "soft" IP, the register layouts differ significantly, 
so separate drivers are required.

Prajna Rajendra Kumar (3):
  spi: microchip: rename driver file and internal identifiers
  spi: dt-binding: document Microchip CoreSPI
  spi: add support for microchip "soft" spi controller
