Christian, have you been able to get a look at those patches? How do you 
want to proceed for patches affecting bcm5301x in the future? Except for 
a few cases (Kconfig, Makefile), support for bcm5301x is orthogonal to 
the other bcm-mobile SoCs, should that be taken care of by the arm-soc 
maintainers directly?

Thanks!
