[U-Boot] [PATCH 2/5] dm: spi: Convert Freescale ESPI driver to driver model

Chuanhua Han chuanhua.han at nxp.com
Tue Apr 23 08:05:53 UTC 2019


Modify the Freescale ESPI driver to support the driver model.
Also resolved the following problems:

===================== WARNING ======================
This board does not use CONFIG_DM_SPI. Please update
the board before v2019.04 for no dm conversion
and v2019.07 for partially dm converted drivers.
Failure to update can lead to driver/board removal
See doc/driver-model/MIGRATION.txt for more info.
====================================================
===================== WARNING ======================
This board does not use CONFIG_DM_SPI_FLASH. Please update
the board to use CONFIG_SPI_FLASH before the v2019.07 release.
Failure to update by the deadline may result in board removal.
See doc/driver-model/MIGRATION.txt for more info.
====================================================
