Subject: [PATCH] ARM: dts: sun8i-h3: add sy8106a to orange pi plus
|
||||
|
||||
The Orange Pi Plus board lacks voltage scaling capabilities in its
|
||||
current form. This results in random freezes during boot when cpufreq is
|
||||
enabled, probably due to wrong voltages.
|
||||
|
||||
This patch (more or less copy/paste from 06139c) does the following
|
||||
things on this board:
|
||||
- enable r_i2c
|
||||
- add sy8106a to the r_i2c bus
|
||||
- have the sy8106a regulate VDD of cpu
|
||||
|
||||
Since the Orange Pi Plus has the same PMU setup as the Orange Pi PC, I
|
||||
simply took min/max/fixed/ramp from the latter DTS. In that file the
|
||||
origin of the values are described by the following comment:
|
||||
|
||||
"The datasheet uses 1.1V as the minimum value of VDD-CPUX,
|
||||
however both the Armbian DVFS table and the official one
|
||||
have operating points with voltage under 1.1V, and both
|
||||
DVFS table are known to work properly at the lowest
|
||||
operating point.
|
||||
Use 1.0V as the minimum voltage instead."
|
||||
|
||||
I have tested this on patch two Orange Pi Plus boards, by running a
|
||||
kernel with this patch and do intermettent runs of cpuburn while
|
||||
monitoring voltage, frequency and temperature. The board runs stable
|
||||
across its operatiing points while showing a reasonable (< 40C)
|
||||
temperature. My Orange Pi PC, when put to the same test, yields similar
|
||||
stable results.
