[PATCH 00/23] spi: fsl-espi: several cleanups, improvements, and few fixes

[Heiner Kallweit]

This patch series includes several cleanups, improvements, and few
smaller fixes. It was successfully tested on a P1014-based
WiFi router with SPI NOR flash.

There are also some functional extensions in the pipe, I'll send
them part of a separate patch set.
