[PATCH 3.14 01/29] media: staging: tighten omap4iss dependencies

From: Greg Kroah-Hartman
Date: Tue Jul 29 2014 - 22:06:38 EST

3.14-stable review patch. If anyone has any objections, please let me know.


From: Arnd Bergmann <arnd@xxxxxxxx>

commit 4856fbd12d69965d3ab680c686222db93872728d upstream.

The OMAP4 camera support depends on I2C and VIDEO_V4L2, both
of which can be loadable modules. This causes build failures
if we want the camera driver to be built-in.

This can be solved by turning the option into "tristate",
which unfortunately causes another problem, because the
driver incorrectly calls a platform-internal interface
for omap4_ctrl_pad_readl/omap4_ctrl_pad_writel.

Instead, this patch just forbids the invalid configurations
and ensures that the driver can only be built if all its
dependencies are built-in.
