Subject: [PATCH] MIPS: ralink: mt7621: avoid to init common ralink reset controller
|
||
|
|
|
||
|
|
[ Upstream commit 76ce51798cb16738a4a28a6662e7344aaf7ef769 ]
|
||
|
|
|
||
|
|
Commit 38a8553b0a22 ("clk: ralink: make system controller node a reset provider")
|
||
|
|
make system controller a reset provider for mt7621 ralink SoCs. Ralink init code
|
||
|
|
also tries to start previous common reset controller which at the end tries to
|
||
|
|
find device tree node 'ralink,rt2880-reset'. mt7621 device tree file is not
|
||
|
|
using at all this node anymore. Hence avoid to init this common reset controller
|
||
|
|
for mt7621 ralink SoCs to avoid 'Failed to find reset controller node' boot
|
||
|
|
error trace error.
|
||
|
|
|
||
|
