Hi Tomasz,
Please don't include other changes in this patch which is for supporting
synchronous mode. If required, should be separated patch.
As a note, others looks ok to me. I think, you need to re-submit only this
one and I will apply your whole series after getting updated this one.
Thanks.
Best regards,
Kgene.

Some boards based on S3C6410 use synchronous clocking, which means that HCLKx2
and other system clocks are generated from APLL instead of MPLL.
This patch adds support for such boards, by calculating hclk2 depending on
the status of S3C_OTHERS_SYNCMUXSEL bit in S3C64XX_OTHERS registers.
