Subject: [PATCH 01/19] irqchip: atmel-aic: fix wrong bit operation for IRQ priority
Date: Mon, 4 Jan 2016 13:28:25 +0900 [thread overview]
Message-ID: <1451881723-2478-2-git-send-email-milo.kim@ti.com> (raw)
In-Reply-To: <1451881723-2478-1-git-send-email-milo.kim@ti.com>
Atmel AIC has common structure for SMR (Source Mode Register).
bit[6:5] Interrupt source type
bit[2:0] Priority level
Other bits are unused.
To update new priority value, bit[2:0] should be cleared first and then
new priority level can be written. However, aic_common_set_priority()
helper clears source type bits instead of priority bits.
This patch fixes wrong mask bit operation.
