Subject: [PATCH V4 0/4] irq: imx-irqsteer: add 32 interrupts chan and multi outputs support
Date: Wed, 20 Feb 2019 11:40:36 +0000 [thread overview]
Message-ID: <1550662447-8565-1-git-send-email-aisheng.dong@nxp.com> (raw)
Not all 64 interrupts may be used in one group. e.g. most irqsteer in
imx8qxp and imx8qm subsystems supports only 32 interrupts.
And one irqsteer channel can support up to 8 output interrupts.
This patch series aims to support 32 interrupts chan and multi output
interrupts.
Tested on:
iMX8QXP MEK with MIPI CSI capture and DC Display
iMX8MQ EVK with MIPI DSI Display
Change Log:
v3->v4:
* no code changes except adding more commit message for Patch 1
Dong Aisheng (4):
dt-binding: irq: imx-irqsteer: use irq number instead of group number
dt-bindings: irq: imx-irqsteer: add multi output interrupts support
irq: imx-irqsteer: change to use reg_num instead of irq_group
irq: imx: irqsteer: add multi output interrupts support
