Subject: [PATCH 01/19] ARM: imx legacy: kzm: move peripheral initialization to .init_late
Date: Mon, 19 Sep 2016 04:37:13 +0300 [thread overview]
Message-ID: <1474249051-10718-1-git-send-email-vz@mleia.com> (raw)
In-Reply-To: <1474248988-10626-1-git-send-email-vz@mleia.com>
The change moves some of peripheral registrations and initializations
(all peripherals dependent on GPIOs) from .init_machine to .init_late
level, this allows to safely shift the shared GPIO controller driver
initialization level after init level of i.MX IOMUXC driver.
The change is tested on qemu kzm target.
