This series adds support for a serial uclass, enabling serial drivers to be converted to use driver model.
With v4, exynos boards all build and a second attempt has been made to add Tegra support via the ns16550 driver, tested on beaver, Jetson-TK1 and seaboard (i.e. 3 of the 4 SoCs in mainline).
To see the current state of driver model, look at u-boot-dm.git branch 'working'. This branch is at 'serial-working'.
Changes in v5: - Add new patch to add a function to look up a chosen node - Add struct udevice declaration - Use /chosen/stdout-path instead of /aliases/console to specify the console
Changes in v4: - Add a binding for sandbox serial - Add a separate Tegra serial driver to deal with the clock issue - Add new CONFIG_TEGRA_SERIAL option to enable dm driver - Remove 'clock-frequency' property from serial nodes - Remove clock frequency setup for ns16550 driver - Remove pre-reloc fdt property - Use hard-coded UART clock from Tegra configuration
Changes in v3: - Add new change to enhance lists_bind_fdt() - Add new patch for tegra serial port details - Add new patch to collect common baud rate code in ns16550 - Add new patch to enable driver model for serial on tegra - Add new patch to move baud rate calculation to ns16550.c - Add new patch to support driver model in ns16550 - Add new patch to use V_NS16550_CLK only in SPL builds - Automatically bind the console even if not marked for pre-relocation - Avoid reordering functions - Change pre-reloc fdt property to 'u-boot,dm-pre-reloc' - Fix typo in commit message
Changes in v2: - Rename struct device to struct udevice
