[linux-sunxi] [PATCH v2] ARM: dts: sunxi: Add regulators for LeMaker BananaPi

2015-08-02 Thread Timo Sigurdsson
sun7i-a20-bananapi.dts doesn't contain regulator nodes for the AXP209 PMU
driver, so add them to allow for voltage-scaling with cpufreq-dt.

Signed-off-by: Timo Sigurdsson 
---
Changes since v1 (RFC):

- Dropped the changes to the cpufreq operating points and renamed the patch
accordingly
- Limited the CPU voltage range so it doesn't exceed the SOC specifications

Thanks for doing this, looks good to me:

p.s.

I've replaced my own patch with this one in my sunxi-wip branch.
