Subject: [PATCH 43/76] ARM: dts: mt8127: enable basic SMP bringup for mt8127
|
||
|
|
|
||
|
|
Add arch timer node to enable arch-timer support. MT8127 firmware
|
||
|
|
doesn't correctly setup arch-timer frequency and CNTVOFF, add
|
||
|
|
properties to workaround this.
|
||
|
|
|
||
|
|
This also set cpu enable-method to enable SMP.
