Subject: [PATCH v4 02/10] irqdomain: add bus token DOMAIN_BUS_WAKEUP
Date: Wed, 13 Mar 2019 15:18:36 -0600 [thread overview]
Message-ID: <20190313211844.29416-3-ilina@codeaurora.org> (raw)
In-Reply-To: <20190313211844.29416-1-ilina@codeaurora.org>
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.
