[PATCH v3 0/8] arm64: rockchip: Initial GeekBox enablement

[Andreas Färber]

Hello,

This series adds initial support for the RK3368 based GeekBox.

Since v2 almost a month has passed with none of the first patches getting queued
despite Heiko offering to squash them himself, so here's a full update.

There were no more replies on the compatible string discussion for Landingship;
I have now adopted Heiko's proposal of using "geekbuying,geekbox-landingship".

v3 does minor cleanups and starts squashing undisputed patches. The power button
is still left separate, inserting cleanups to align all RK3368 boards at least.

On next-20160304 the GMAC seems to have regressed, it no longer finds the PHY:

libphy: PHY stmmac-0:ffffffff not found
eth0: Could not attach to PHY
stmmac_open: Cannot attach to PHY (error: -19)

For v2 I may have screwed up testing the Landingship FDT; I now ran into this:

rk3x-i2c ff140000.i2c: using default SCL frequency: 100000
INFO: rcu_preempt detected stalls on CPUs/tasks:
        1-...: (1 GPs behind) idle=481/140000000000000/0 softirq=130/131 fqs=5250 
        (detected by 7, t=5254 jiffies, g=-239, c=-240, q=90)
Task dump for CPU 1:

Call trace:
[<ffffff8008085c5c>] __switch_to+0xc4/0xd0
[<ffffff8008bc1000>] nonblocking_pool_data+0x20/0x80

Keeping i2c1 disabled avoids that; i2c2 does not run into such problems.
A quick git-grep shows that I'm the first actual user of i2c1 (and i2c2),
so maybe something's wrong with clocks or pinctrl?

Regards,
Andreas
