Subject: ARM: OMAP2+: gpmc: fix: DT ONENAND child nodes not probed when
MTD_ONENAND is built as module
From: Pekon Gupta <[email protected]>
commit 980386d2d6d49e0b42f48550853ef1ad6aa5d79a upstream.
Fixes: commit 75d3625e0e86b2d8d77b4e9c6f685fd7ea0d5a96
ARM: OMAP2+: gpmc: add DT bindings for OneNAND
OMAP SoC(s) depend on GPMC controller driver to parse GPMC DT child nodes and
register them platform_device for ONENAND driver to probe later. However this
does
not happen if generic MTD_ONENAND framework is built as module
(CONFIG_MTD_ONENAND=m).
Therefore, when MTD/ONENAND and MTD/ONENAND/OMAP2 modules are loaded, they are
unable
to find any matching platform_device and remain un-binded. This causes on board
ONENAND flash to remain un-detected.
This patch causes GPMC controller to parse DT nodes when
CONFIG_MTD_ONENAND=y || CONFIG_MTD_ONENAND=m
