OMAP4 Mux FW question

OMAP4 Mux FW question

[archit taneja]

Hi,

Does the current Mux Framework support configuration of Registers like 
CONTROL_DSIPHY, CONTROL_USB etc in SYSCTRL_PADCONF_CORE in OMAP4? Could 
someone guide me to an example?

Thanks,
Archit

Hi Archit,
 Those control registers are not a part of the mux list.
 So the mux framework does not support configuring them.
 Only the pad mux registers are configured.

Thanks,
 Sricharan

If they are not part of MUX registers then you could
use control APIs directly. They should work.

omap4_ctrl_pad_readl() and omap4_ctrl_pad_writel()

I tried this out, it works fine with this.
