All SPI drivers are converted to DM_SPI but 3 drivers still operate in nondm mode for SPL due to footprint constraints. Update the migration status for it. Signed-off-by: Jagan Teki <jagan@amarulasolutions.com>

Migration Schedule
|
|
==================
|
|
|
|
U-Boot has been migrating to a new driver model since its introduction in
|
|
2014. This file describes the schedule for deprecation of pre-driver-model
|
|
features.
|
|
|
|
CONFIG_DM
|
|
---------
|
|
|
|
* Status: In progress
|
|
* Deadline: 2020.01
|
|
|
|
Starting with the 2010.01 release CONFIG_DM will be enabled for all boards.
|
|
This does not concern CONFIG_DM_SPL and CONFIG_DM_TPL. The conversion date for
|
|
these configuration items still needs to be defined.
|
|
|
|
CONFIG_DM_MMC
|
|
-------------
|
|
|
|
* Status: In progress
|
|
* Deadline: 2019.04
|
|
|
|
The subsystem itself has been converted and maintainers should submit patches
|
|
switching over to using CONFIG_DM_MMC and other base driver model options in
|
|
time for inclusion in the 2019.04 rerelease.
|
|
|
|
CONFIG_DM_USB
|
|
-------------
|
|
|
|
* Status: In progress
|
|
* Deadline: 2019.07
|
|
|
|
The subsystem itself has been converted along with many of the host controller
|
|
and maintainers should submit patches switching over to using CONFIG_DM_USB and
|
|
other base driver model options in time for inclusion in the 2019.07 rerelease.
|
|
|
|
CONFIG_SATA
|
|
-----------
|
|
|
|
* Status: In progress
|
|
* Deadline: 2019.07
|
|
|
|
The subsystem itself has been converted along with many of the host controller
|
|
and maintainers should submit patches switching over to using CONFIG_AHCI and
|
|
other base driver model options in time for inclusion in the 2019.07 rerelease.
|
|
|
|
CONFIG_BLK
|
|
----------
|
|
|
|
* Status: In progress
|
|
* Deadline: 2019.07
|
|
|
|
In concert with maintainers migrating their block device usage to the
|
|
appropriate DM driver, CONFIG_BLK needs to be set as well. The final deadline
|
|
here coincides with the final deadline for migration of the various block
|
|
subsystems. At this point we will be able to audit and correct the logic in
|
|
Kconfig around using CONFIG_PARTITIONS and CONFIG_HAVE_BLOCK_DEVICE and make
|
|
use of CONFIG_BLK / CONFIG_SPL_BLK as needed.
|
|
|
|
CONFIG_DM_SPI / CONFIG_DM_SPI_FLASH
|
|
-----------------------------------
|
|
|
|
Board Maintainers should submit the patches for enabling DM_SPI and DM_SPI_FLASH
|
|
to move the migration with in the deadline.
|
|
|
|
Partially converted::
|
|
|
|
drivers/spi/fsl_espi.c
|
|
drivers/spi/mxc_spi.c
|
|
drivers/spi/sh_qspi.c
|
|
|
|
* Status: In progress
|
|
* Deadline: 2019.07
|
|
|
|
CONFIG_DM_PCI
|
|
-------------
|
|
Deadline: 2019.07
|
|
|
|
The PCI subsystem has supported driver model since mid 2015. Maintainers should
|
|
submit patches switching over to using CONFIG_DM_PCI and other base driver
|
|
model options in time for inclusion in the 2019.07 release.
|
|
|
|
|
|
CONFIG_DM_VIDEO
|
|
---------------
|
|
Deadline: 2019.07
|
|
|
|
The video subsystem has supported driver model since early 2016. Maintainers
|
|
should submit patches switching over to using CONFIG_DM_VIDEO and other base
|
|
driver model options in time for inclusion in the 2019.07 release.
|
|
|
|
CONFIG_DM_ETH
|
|
-------------
|
|
Deadline: 2020.07
|
|
|
|
The network subsystem has supported the driver model since early 2015.
|
|
Maintainers should submit patches switching over to using CONFIG_DM_ETH and
|
|
other base driver model options in time for inclusion in the 2020.07 release.
