Subject: [PATCH 1/7] mtd: nand: davinci: fix driver registration
Date: Wed, 20 Nov 2013 17:22:19 +0200 [thread overview]
Message-ID: <1384960945-14528-2-git-send-email-ivan.khoronzhuk@ti.com> (raw)
In-Reply-To: <1384960945-14528-1-git-send-email-ivan.khoronzhuk@ti.com>
When kernel is booted using DT, there is no guarantee that Davinci
NAND device has been created already at the time when driver init
function is executed. Therefore, platform_driver_probe() can't be used
because this may result the Davinci NAND driver will never be probed.
The driver probing has to be made with core mechanism.
