Thanks.

OK, my bad, haven't though about it, sorry. Will remember to do it next time 
such series update happens.

By the way, patch 14 has been updated as well.

Best regards,

OK, thanks.

I don't really understand this decision, but if you really insist...

Still, I think current setup is wrong, because you need to specify both SoCs 
in drivers and both Kconfig entries must have "select" and "depends on" clauses 
duplicated, while there are places currently where only one has been specified 
by mistake.

So if we can't get this duplication removed, I'd suggest introducing 
CONFIG_SOC_EXYNOS4X12 which would represent the whole SoC series and making 
existing two entries just simple bools selecting the new one.

Best regards,
Tomasz
