Jiri Slaby 4bb1667255 build some drivers only when compile-testing ... Some drivers can be built on more platforms than they run on. This is a burden for users and distributors who package a kernel. They have to manually deselect some (for them useless) drivers when updating their configs via oldconfig. And yet, sometimes it is even impossible to disable the drivers without patching the kernel. Introduce a new config option COMPILE_TEST and make all those drivers to depend on the platform they run on, or on the COMPILE_TEST option. Now, when users/distributors choose COMPILE_TEST=n they will not have the drivers in their allmodconfig setups, but developers still can compile-test them with COMPILE_TEST=y. Now the drivers where we use this new option: * PTP_1588_CLOCK_PCH: The PCH EG20T is only compatible with Intel Atom processors so it should depend on x86. * FB_GEODE: Geode is 32-bit only so only enable it for X86_32. * USB_CHIPIDEA_IMX: The OF_DEVICE dependency will be met on powerpc systems -- which do not actually support the hardware via that method. * INTEL_MID_PTI: It is specific to the Penwell type of Intel Atom device. [v2] * remove EXPERT dependency [gregkh - remove chipidea portion, as it's incorrect, and also doesn't apply to my driver-core tree] Signed-off-by: Jiri Slaby <jslaby@suse.cz> Cc: Andrew Morton <akpm@linux-foundation.org> Cc: Linus Torvalds <torvalds@linux-foundation.org> Cc: Jeff Mahoney <jeffm@suse.com> Cc: Alexander Shishkin <alexander.shishkin@linux.intel.com> Cc: linux-usb@vger.kernel.org Cc: Florian Tobias Schandinat <FlorianSchandinat@gmx.de> Cc: linux-geode@lists.infradead.org Cc: linux-fbdev@vger.kernel.org Cc: Richard Cochran <richardcochran@gmail.com> Cc: netdev@vger.kernel.org Cc: Ben Hutchings <ben@decadent.org.uk> Cc: "Keller, Jacob E" <jacob.e.keller@intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2013-06-24 16:41:32 -07:00
