Subject: [PATCH v3 4/6] syscon: Decrease driver registration priority
Date: Mon, 16 May 2016 09:45:59 -0700 [thread overview]
Message-ID: <1463417161-28634-5-git-send-email-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <1463417161-28634-1-git-send-email-andrew.smirnov@gmail.com>
A number of devices on i.MX6 list "syscon" as second compatibility
string, among them, most importantly, is "iomuxv3" pinmux driver, which
gets probed at "postcore_initcall". Probing this driver at
"core_initcall" results in "syscon" driver usurping pinmux device and
preventing "iomuxv3" driver from loading and correctly initializing
pinmux of the system (which in turn results in a lot of sadness).
Moving this driver to be initialized at "device_initcall" time resolves
the issue.
