[U-Boot] [PATCH v4 0/6] board: sama5d3: convert boards to support DM/DT
The purpose of patch set is to convert the board to support device tree and driver model, and enable the early debug UART as well. It is based on the patch set: [PATCH v8 0/2] pinctrl: at91: Add pinctrl driver https://lists.denx.de/pipermail/u-boot/2017-March/284577.html
Changes in v4: - Remove wrong using CONFIG_PHY_MICREL. - Remove the ethernet init code completely.
Changes in v3: - Convert the macb to support DM and clean up macb init code. - Remain the SPI speed macros. - Update the config options for SPL. - Update the commit log. - Remove the unneeded dbgu init during board_early_init_f stage. - Use CONFIG_DEBUG_UART_CLOCK as the input clock for the early debug uart. - Drop [PATCH] configs: sama5d3_xplained: move CONFIG_SYS_NO_FLASH to defconfig. - Rebase on v2017.03.
Changes in v2: - rebase on the patch set: [PATCH v3 0/8] board: sama5d4: convert boards to support DM/DT http://lists.denx.de/pipermail/u-boot/2017-February/280506.html

Update the configuration files to support the device tree and driver model, so do SPL. The device clock and pins configuration are handled by the clock and the pinctrl drivers respectively.

Changes in v4: None Changes in v3: - Convert the macb to support DM and clean up macb init code. - Remain the SPI speed macros. - Update the config options for SPL. - Update the commit log. - Remove the unneeded dbgu init during board_early_init_f stage. - Use CONFIG_DEBUG_UART_CLOCK as the input clock for the early debug uart. - Drop [PATCH] configs: sama5d3_xplained: move CONFIG_SYS_NO_FLASH to defconfig. - Rebase on v2017.03.
Changes in v2: - rebase on the patch set: [PATCH v3 0/8] board: sama5d4: convert boards to support DM/DT http://lists.denx.de/pipermail/u-boot/2017-February/280506.html
