From 808a504f394bdd68c282c461960ad94eb41e6502 Mon Sep 17 00:00:00 2001 From: Lina Iyer Date: Fri, 13 Sep 2019 15:59:09 -0600 Subject: [PATCH] FROMLIST: irqdomain: add bus token DOMAIN_BUS_WAKEUP A single controller can handle normal interrupts and wake-up interrupts independently, with a different numbering space. It is thus crucial to allow the driver for such a controller discriminate between the two. A simple way to do so is to tag the wake-up irqdomain with a "bus token" that indicates the wake-up domain. This slightly abuses the notion of bus, but also radically simplifies the design of such a driver. Between two evils, we choose the least damaging.
