Subject: [PATCH v6 1/6] regmap: add a new macro:REGMAP_IRQ_REG_LINE(_id, _reg_bits)
Date: Tue, 30 Oct 2018 18:07:56 +0800 [thread overview]
Message-ID: <1540894081-31270-2-git-send-email-tony.xie@rock-chips.com> (raw)
In-Reply-To: <1540894081-31270-1-git-send-email-tony.xie@rock-chips.com>
if there are lots of irqs for a device and the register addresses for these
irqs is continuous, we can use this macro to initialize regmap_irq value.
