Subject: [PATCH 00/10] Patches to get dm814x-evm booting to NFSroot

Hi all,

Here are some fixes for v4.5 merge window to get dm814x-evm booting.
While hp t410 boots based on the bootloader clocks, dm814x-evm needs
more things configured. Especially the clock dts entries were all
wrong and just happened to be harmless on hp t410.

To boot, you probably want to use v4.4-rc3 because of commit 29f5b34ca1a1
("arm: omap2+: add missing HWMOD_NO_IDLEST in 81xx hwmod data") and also
manually apply commit 0db19b850468 ("net: cpsw: Fix ethernet regression
for dm814x") from Linux next.

I have more changes coming up after this series after I clean them
up a bit. Here's a brief status update for people:

What's working after this series on dm814x-evm and hp t410:

- Timers

- Serial

- Ethernet

- DMA

- I2C (only tested so far with i2cdetect -r 0)

- GPIO (only tested with additional MMC patches for card detect)

I have the following additional patches coming soonish:

- Basic ADPLL clock driver

- MMC support

- USB support

- Minimal j5eco-evm support

Should work with just configuration:

- [PATCH 0/3] pwm: omap: Add PWM support using dual-mode timers

I'm not working on any of the accelerators or graphics FYI. If somebody
has patches coming for those please notify on the linux-omap and
linux-arm-kernel mailings lists so we can avoid duplicate work.

Cheers,

Tony
