Subject: [PATCH] MIPS: Octeon: Add twsi interrupt initialization for OCTEON
|
||
|
|
3XXX, 5XXX, 63XX
|
||
|
|
|
||
|
|
In octeon_3xxx.dts file, there is a definiton for twsi/twsi2 interrupts.
|
||
|
|
But there is no code for initialization of this interrupts. This patch adds
|
||
|
|
code for initialization of twsi interrupts.
