In order to convert the Freescale ESPI driver to the driver model, there are 5 related patches in the current patch set:
0001-spl-dm-disable-SPI-DM-flash-for-non-DM-SPL.patch 0002-dm-spi-Convert-Freescale-ESPI-driver-to-driver-model.patch 0003-powerpc-dts-t2080-add-espi-controller-node-support.patch 0004-powerpc-dts-t2080qds-add-espi-slave-nodes-support.patch 0005-configs-enable-espi-device-module-in-T2080QDS.patch
The first patch is to solve the problem that spl can't work when spiboot, and this is required for SPI boot.
The other four patches are supported by the driver model. This patchset already supports the full dm mode, and fsl_espi driver support both OF_CONTROL and PLATDATA.
