[OpenWrt-Devel] [PATCH 00/22] Conversion of ARMv4 Gemini to DT and multiplatform

[Linus Walleij]

I got a Gemini platform from Florian Fainelli over at OpenWRT
some time back. I finally got around to "future-proofing" the
platform, which was the idea when he paintakingly sent the box
over to me.

This is the result: Gemini is converted to device tree and
multiplatform, all existing drivers are rewritten into their
proper subsystems and the old board-specific and machine-specific
code is deleted.

I would ideally like the irqchip, clocksource, gpio, rtc and MTD
patches (and bindings) to simply be merged into the respective
subsystem and the remaining ARM/ARM SoC patches funnelled to the
ARM SoC tree in a single pull request, lock stock and barrel,
with changes to board files and DTS additions in one go. But I
guess I could also switch the DTS files to a separate branch.

The OpenWRT tree still have a whole bunch of significant out-of
tree drivers:

- Watchdog
- GMAC (ethernet)
- FOT2G USB EHCI host
- PATA
- PCI

But I do not see any big obstacle in porting these over to be
probed from the device tree and upstreamed on top of this patch
series. I might tinker with it if I get time.

The out-of-tree code can be found here:
