Due to adding various new functionalities with SPI and SPI-FLASH subsystems which are rounding in Mailing list for year+ [1] these long term supporting spi driver which never seen any update with driver-model conversion.
We support to write another stack code for supporting these legacy stuff, but things become more difficult. So I'm finally giving deadlines for these drivers to respective driver or board developers to convert them as soon as possible.
PS: We all agree some special platforms has some difficulties with dm-conversion let's discuss.
No dm conversion yet: ---------------------------- drivers/spi/cf_spi.c drivers/spi/fsl_espi.c drivers/spi/lpc32xx_ssp.c drivers/spi/mpc8xx_spi.c drivers/spi/mpc8xxx_spi.c drivers/spi/mxs_spi.c drivers/spi/sh_qspi.c drivers/spi/sh_spi.c drivers/spi/soft_spi_legacy.c
Partially converted: ------------------------- drivers/spi/atcspi200_spi.c drivers/spi/atmel_spi.c drivers/spi/davinci_spi.c drivers/spi/fsl_dspi.c drivers/spi/fsl_qspi.c drivers/spi/kirkwood_spi.c drivers/spi/mxc_spi.c drivers/spi/omap3_spi.c drivers/spi/ti_qspi.cM
I would like to see these legacy drivers with full dm-conversion or zapped in v2018.09 version of U-Boot.
