Patch 1/2 Migrates the fsl-(e)spi driver to use the generic master queuing. Avoids the "master is unqueued, this is deprecated" warning.
Patch 2/2 Adds (un)prepare_transfer_hardware calls to (re)set SPMODE_ENABLE. Reduces power consumption when SPI is idle. I successfully tested the backported version of both patches on a wireless router TP-Link TL-WDR4900 (P1014/mpc85xx-based: fsl-espi) with openwrt and kernel 3.14.25 (newer kernels not yet supported). Due to missing hw I wasn't able to test patch 1 with fsl-spi.
