[PATCHV3 3/4] OMAP3: Correct width for CLKSEL Fields

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



DPLL4 M, M3, M4, M5 and M6 field width has been increased by 1 bit in
3630.This patch has changes to accommodate this in CM dynamically based
on chip version. Primary changes are
1. Added clksel_mask_3630 to take care clksel width changes
2. CLock nodes which are newly added for 3630 are marked under CK_363X
3. Clock nodes which have changes for 3630 are marked as CK_3XXX | CK_363X
4. Clock nodes which are unchanged for 3630 are retained as CK_3XXX
5. 3630 specific Clock rates are marked as RATE_IN_363X
