From 81c44c2b2ce358b1c5fe0065dc5d2e2010f39f1b Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Thu, 24 Apr 2014 13:28:20 +0100 Subject: [PATCH] video/omap: fix modular build The framebuffer layer can be a loadable module, which forces omapfb to be a module as well. However, this breaks the lcd drivers, which are linked into the omapfb driver but each have their own module_init() function. To solve this, we split out the lcd drivers into separate modules and export omapfb_register_panel, which is the only interface required between the main omapfb driver and the lcd panel drivers. We also have to introduce a new Kconfig symbol for H3, since that lcd driver has a dependency on TPS65010, which we can express better in Kconfig than Makefile syntax.
