Subject: [PATCH] DT: rockchip: Fix stability issues with the 'performance'
|
||||
governor on rock960
|
||||
Date: Tue, 16 Oct 2018 16:00:20 +0200

||||

||||

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