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
