1.. SPDX-License-Identifier: GPL-2.0+ 2 3Migration Schedule 4================== 5 6U-Boot has been migrating to a new driver model since its introduction in 72014. This file describes the schedule for deprecation of pre-driver-model 8features. 9 10CONFIG_DM 11--------- 12 13* Status: In progress 14* Deadline: 2020.01 15 16Starting with the 2010.01 release CONFIG_DM will be enabled for all boards. 17This does not concern CONFIG_DM_SPL and CONFIG_DM_TPL. The conversion date for 18these configuration items still needs to be defined. 19 20CONFIG_DM_MMC 21------------- 22 23* Status: In progress 24* Deadline: 2019.04 25 26The subsystem itself has been converted and maintainers should submit patches 27switching over to using CONFIG_DM_MMC and other base driver model options in 28time for inclusion in the 2019.04 rerelease. 29 30CONFIG_DM_USB 31------------- 32 33* Status: In progress 34* Deadline: 2019.07 35 36The subsystem itself has been converted along with many of the host controller 37and maintainers should submit patches switching over to using CONFIG_DM_USB and 38other base driver model options in time for inclusion in the 2019.07 rerelease. 39 40CONFIG_SATA 41----------- 42 43* Status: In progress 44* Deadline: 2019.07 45 46The subsystem itself has been converted along with many of the host controller 47and maintainers should submit patches switching over to using CONFIG_AHCI and 48other base driver model options in time for inclusion in the 2019.07 rerelease. 49 50CONFIG_BLK 51---------- 52 53* Status: In progress 54* Deadline: 2019.07 55 56In concert with maintainers migrating their block device usage to the 57appropriate DM driver, CONFIG_BLK needs to be set as well. The final deadline 58here coincides with the final deadline for migration of the various block 59subsystems. At this point we will be able to audit and correct the logic in 60Kconfig around using CONFIG_PARTITIONS and CONFIG_HAVE_BLOCK_DEVICE and make 61use of CONFIG_BLK / CONFIG_SPL_BLK as needed. 62 63CONFIG_DM_SPI / CONFIG_DM_SPI_FLASH 64----------------------------------- 65 66Board Maintainers should submit the patches for enabling DM_SPI and DM_SPI_FLASH 67to move the migration with in the deadline. 68 69No dm conversion yet:: 70 71 drivers/spi/fsl_espi.c 72 drivers/spi/lpc32xx_ssp.c 73 drivers/spi/sh_spi.c 74 drivers/spi/soft_spi_legacy.c 75 76* Status: In progress 77* Deadline: 2019.04 78 79Partially converted:: 80 81 drivers/spi/davinci_spi.c 82 drivers/spi/fsl_dspi.c 83 drivers/spi/kirkwood_spi.c 84 drivers/spi/mxc_spi.c 85 drivers/spi/mxs_spi.c 86 drivers/spi/omap3_spi.c 87 drivers/spi/sh_qspi.c 88 89* Status: In progress 90* Deadline: 2019.07 91 92 93CONFIG_DM_PCI 94------------- 95Deadline: 2019.07 96 97The PCI subsystem has supported driver model since mid 2015. Maintainers should 98submit patches switching over to using CONFIG_DM_PCI and other base driver 99model options in time for inclusion in the 2019.07 release. 100 101 102CONFIG_DM_VIDEO 103--------------- 104Deadline: 2019.07 105 106The video subsystem has supported driver model since early 2016. Maintainers 107should submit patches switching over to using CONFIG_DM_VIDEO and other base 108driver model options in time for inclusion in the 2019.07 release. 109 110CONFIG_DM_ETH 111------------- 112Deadline: 2020.07 113 114The network subsystem has supported the driver model since early 2015. 115Maintainers should submit patches switching over to using CONFIG_DM_ETH and 116other base driver model options in time for inclusion in the 2020.07 release. 117
