Subject: [PATCH v2 6/6] i.MX: Do not explicitly call l2x0_of_init()
Date: Tue, 14 Jun 2016 18:29:53 -0700	[thread overview]
Message-ID: <1465954193-5894-7-git-send-email-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <1465954193-5894-1-git-send-email-andrew.smirnov@gmail.com>

There's no need to explicitly call l2x0_of_init() since it will be
called as a part of init_IRQ() (see arch/arm/kernel/irq.c for
details). This way we can simplify imx_init_l2cache() and ditch the call
to it on i.MX35 (which does not claim compatibility with
"arm,pl310-cache") alltogether.
