Since the removal of CONFIG_REGULATOR_DUMMY option, the touchscreen stopped working. This patch enables the "replacement" for REGULATOR_DUMMY and allows the touchscreen to work even though there is no regulator for "vcc".

commit 165235180ff61f0012ea68a299e46daec43dcaa7 upstream.

mvebu_armada375_smp_wa_init is only used on armada 375 but is defined
for all mvebu machines. As it calls a function that is only provided
sometimes, this can result in a link error:

To solve this, we can just change the existing #ifdef around the
function to also check for Armada375 SMP platforms.

ARM: BCM: put back ARCH_MULTI_V7 dependency for mobile 2015-03-06T22:57:36+00:00 Arnd Bergmann arnd@arndb.de 2015-01-23T19:59:10+00:00 49fa2998b5e19c9f216fa3951c318d1a07b4fd68 commit ff34cae5b4fc7a84113d7c7e8611ba87a7c31dba upstream. A recent cleanup rearranged the Kconfig file for mach-bcm and accidentally dropped the dependency on ARCH_MULTI_V7, which makes it possible to now build the two mobile SoC platforms on an ARMv6-only kernel, resulting in a log of Kconfig warnings like warning: ARCH_BCM_MOBILE selects ARM_ERRATA_775420 which has unmet direct dependencies (CPU_V7) and which of course cannot work on any machine.
