I plan to use VPU of i.MX515.
So I read MCIMX51RM Rev. 1 2/2010 but I can't find how to set a decoding core clock domain (cclk).
I know the decoding core clock comes from the CCM module because I found the following description in section 61.2.1.
All VPU input clock and reset sources come from the i.MX51 CCM module. The VPU does not do clock gating internally.
However, I can't understand which register do I set.
Could you specify which register do I set to use VPU ?
According to the section 61.4.2 of RM, the decoding core clock domain's frequency can scale done through the VPU API.
I can't find the API in L2.6.35_10.11.01_ER_docs/doc/mx5/i.MX5x_Linux_VPU_API.pdf.
Which VPU API can set the core clock frequency ?
