Hello
I'm using an omap 3530 device, running linux 2.6.37 from PSP (with some changes we've made).
In the process of reducing power consumption, I'm trying to turn unused components off.
I'm doing the following writes: (based on the technical reference manual)
address value
{"CM_CLKEN_PLL_IVA2", 0x48004004 , 0x00000031 },
{"CM_FCLKEN_IVA2", 0x48004000 , 0x00000000 },
{"PM_WKDEP_IVA2", 0x483060C8 , 0x00000000 },
{"PM_PWSTCTRL_IVA2", 0x483060E0 , 0x00ff0f04 },
{"CM_AUTOIDLE_PLL_IVA2", 0x48004034 , 0x00000001 },
{"CM_CLKSTCTRL_IVA2", 0x48004048 , 0x00000003 },
And then I'm reading PM_PWSTST_IVA2 (0x483060E4) I get 0x555, meaning bit 2 is on, so IVA2 domain logic is on.
How can I turn this component completely off?
Thanks
Tamar
