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
