In Reference Manual of i.MX6Dual/Quad(IMX6DQRM.pdf) rev 4 09/2017,
It was modified CCM_CLPCR register field descriptions from IMX6DQRM.pdf rev3 07/2015.
But it seems some mistake,
1) Allocate same bit (bit 21) of following register bits.
2) Allocate same bit (bit19) of following register bits.
3) Why it has no description in B.1.19 CCM Revision History?
I checked a IMX6Solo/DualLite reference manual(IMX6SDLRM.pdf) rev3 and it have same problem.
Please suggest a correct field of this register.
