Hi,
The following patch fixes a wrong container_of usage for omap3630.
All sub clock of dpll4 that do not use a reset value as divider are
affected.
For instance CAM_MCLK is 216 MHz instead of the asked 172,8 MHz
Any user of this clock is affected. This is the case for instance if
CAM_XCLKA is used to provide clock for an external camera.
Beyond wrong frequency setting, this is also a potential oops waiting
to bite any omap3isp user, since a wrong pointer is dereferenced, and
content of this pointer is used to do __raw_writel / __raw_readl.
v2 :
Follow Mike Turquette's comment and use clock framework instead of
directly accessing register.
Regards,
Jean-Philippe Fran?ois
