Subject: [PATCH 1/5] arm64: dts: rockchip: Split out common nodes for Rock960
e336be
 based boards
e336be
e336be
Since the same family members of Rock960 boards (Rock960 and Ficus)
e336be
share the same configuration, split out the common nodes into a common
e336be
dtsi file for reducing code duplication. The board specific nodes for
e336be
Ficus boards are then placed in corresponding board DTS file.

Subject: [PATCH 5/5] DT: rockchip: Fix stability issues with the 'performance'
e336be
 governor on rock960
e336be
e336be
When the performance governor is set as default, the rock960 hangs
e336be
around one minute after booting, whatever the activity is (idle, key
e336be
pressed, loaded, ...).
e336be
e336be
Based on the commit log found at https://patchwork.kernel.org/patch/10092377/
e336be
e336be
"vdd_log has no consumer and therefore will not be set to a specific
e336be
voltage. Still the PWM output pin gets configured and thence the vdd_log
e336be
output voltage will changed from it's default. Depending on the idle
e336be
state of the PWM this will slightly over or undervoltage the logic supply
e336be
of the RK3399 and cause instability with GbE (undervoltage) and PCIe
e336be
(overvoltage). Since the default value set by a voltage divider is the
e336be
correct supply voltage and we don't need to change it during runtime we
e336be
remove the rail from the devicetree completely so the PWM pin will not
e336be
be configured."
e336be
e336be
After removing the vdd-log from the rock960's specific DT, the board
e336be
does no longer hang and shows a stable behavior.
e336be
e336be
Apply the same change for the rock960 by removing the vdd-log from the
e336be
DT.
