| Subject: ARM: OMAP2+: gpmc: fix: DT ONENAND child nodes not probed when MTD_ONENAND is built as module |
| |
| From: Pekon Gupta <pekon@ti.com> |
| |
| 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 |
