Subject: [PATCH v13 04/12] mailbox: mediatek: cmdq: move the CMDQ_IRQ_MASK into cmdq driver data
Date: Tue, 20 Aug 2019 16:36:27 +0800 [thread overview]
Message-ID: <20190820083635.5404-5-bibby.hsieh@mediatek.com> (raw)
In-Reply-To: <20190820083635.5404-1-bibby.hsieh@mediatek.com>
The interrupt mask and thread number has positive correlation,
so we move the CMDQ_IRQ_MASK into cmdq driver data and calculate
it by thread number.
