This adds support for the Olimex A20-OLinuXino-Lime2
https://www.olimex.com/Products/OLinuXino/A20/A20-OLinuXIno-LIME2
Differences to previous Lime boards are 1GB RAM and gigabit ethernet

changes for v2
add axp209 regulators node
changes for v3
add reg_axp_ipsout regulator
follow suggestion by Chen-Yu in
http://lists.infradead.org/pipermail/linux-arm-kernel/2014-October/292645.html
on parenting the regulators which gives:
[ 0.879031] LDO1: 1300 mV
[ 0.881986] LDO1: supplied by axp-ipsout
[ 0.886609] LDO2: 1800 <--> 3300 mV at 3000 mV
[ 0.891202] LDO2: supplied by axp-ipsout
[ 0.895584] LDO3: 700 <--> 3500 mV at 2275 mV
[ 0.900082] LDO3: supplied by axp-ipsout
[ 0.904300] LDO4: 1250 <--> 3300 mV at 2800 mV
[ 0.908877] LDO4: supplied by axp-ipsout
[ 0.913481] LDO5: 1800 <--> 3300 mV at 2800 mV
[ 0.918070] LDO5: supplied by axp-ipsout
[ 0.922474] DCDC2: 700 <--> 2275 mV at 1400 mV
[ 0.927074] DCDC2: supplied by axp-ipsout
[ 0.931538] DCDC3: 700 <--> 3500 mV at 1250 mV
[ 0.936159] DCDC3: supplied by axp-ipsout
[ 0.940253] axp20x 0-0034: AXP20X driver loaded
I gave up trying to build this on top of linux-next as over the last couple
of days linux-next stops somewhere around probing the sata driver, not
always in exactly the same place though. I don't get anywhere near the
previous mmc related issue.
This patchset is based on top of
git://git.kernel.org/pub/scm/linux/kernel/git/mripard/linux.git sunxi/for-next
429823087fec3d3138c72f2910d36d3d8d0733a7
with http://lists.infradead.org/pipermail/linux-arm-kernel/2014-September/288901.html
and http://lists.infradead.org/pipermail/linux-arm-kernel/2014-September/283341.html
added on top.
