Subject: [PATCH v3 20/37] ARM: davinci: aintc: move timer-specific irq_set_handler() out of irq.c
Date: Tue, 12 Feb 2019 11:38:18 +0100 [thread overview]
Message-ID: <20190212103835.7768-21-brgl@bgdev.pl> (raw)
In-Reply-To: <20190212103835.7768-1-brgl@bgdev.pl>
From: Bartosz Golaszewski <bgolaszewski@baylibre.com>
I've been unable to figure out exactly why, but it seems that the
IRQ_TINT1_TINT34 interrupt for timer 1 needs to be handled as a
level irq, not edge like all others.
Let's move the handler setup out of the aintc driver where it's lived
since the beginning and into the dm* SoC-specific files where it
belongs.
