Subject: [PATCH] irqchip/qeic: merge qeic init code from platforms to a common
|
|
function
|
|
|
|
The codes of qe_ic init from a variety of platforms are redundant,
|
|
merge them to a common function and put it to irqchip/irq-qeic.c
|
|
|
|
For non-p1021_mds mpc85xx_mds boards, use "qe_ic_init(np, 0,
|
|
qe_ic_cascade_low_mpic, qe_ic_cascade_high_mpic);" instead of
|
|
"qe_ic_init(np, 0, qe_ic_cascade_muxed_mpic, NULL);".
|
|
|
|
qe_ic_cascade_muxed_mpic was used for boards has the same interrupt
|
|
number for low interrupt and high interrupt, qe_ic_init has checked
|
|
if "low interrupt == high interrupt"
|
