[PATCH RESEND 0/9] ARM: davinci: DT boot support for DA850

[PATCH RESEND 0/9] ARM: davinci: DT boot support for DA850

[Sekhar Nori]

This series adds basic DT boot support for DA850 EVM and EnBW CMC board.
It applies to master branch of Linux DaVinci tree[1].

Resending this because I missed copying the DT and Documentation folks
last time around. Sorry about that. There is no change in patch contents.

Thanks,
Sekhar

[PATCH 1/9] ARM: davinci: uncompress.h: bail out if uart not initialized

[Sekhar Nori]

Bail out of UART access functions in uncompress.h if the uart
port is not setup. This will happen when booting from DT since
machine type matching does not work in this case. This may also
happen if a correct machine type is not setup by bootloader.

[PATCH 2/9] ARM: davinci: serial: provide API to initialze UART clocks

[Sekhar Nori]

Provide an API to initialize a UART clock. Refactor existing
davinci_serial_init() to separate out the part which enables
the clock.

This will later be used to help DA850 DT boot support.

[PATCH 7/9] ARM: davinci: add support for am1808 based EnBW CMC board

[Sekhar Nori]

From: Heiko Schocher <hs-ynQEQJNshbs@public.gmane.org>

This board supports:

- AM1808 based board
- 64 MiB DDR ram
- 2 MiB Nor flash
- 128 MiB NAND flash
- use internal RTC
- I2C support
- hwmon lm75 support
- UBI/UBIFS support
- MMC support
- USB OTG support

This patch adds the basic DTS file enabling the serial ports.
Other features will be added in due course of time.
