Subject: [PATCH v4 07/11] thermal: sun8i: rework for ths irq handler func
Date: Sun, 23 Jun 2019 12:42:02 -0400
Message-ID: <20190623164206.7467-8-tiny.windzz@gmail.com> (raw)
In-Reply-To: <20190623164206.7467-1-tiny.windzz@gmail.com>

Here, we do something to prepare for the subsequent
support of multiple platforms.

1) rename sun50i_h6_irq_thread to sun8i_irq_thread, because
   this function should be suitable for all platforms.

2) introduce irq_ack callback to mask interrupt register
   differences.
