Commit Message

Dario Binacchi April 1, 2021, 7:37 p.m. UTC
Registers for adjusting the spread spectrum clocking (SSC) have been
added. As reported by the TI spruh73x RM, SSC is supported only for LCD
and MPU PLLs, but the CM_SSC_DELTAMSTEP_DPLL_XXX and
CM_SSC_MODFREQDIV_DPLL_XXX registers, as well as the enable field in the
CM_CLKMODE_DPLL_XXX registers are mapped for all PLLs (CORE, MPU, DDR,
PER, DISP).

Changes in v4:
- Add SSC registers for CORE, DDR and PER PLLs.
- Update commit message.

Changes in v3:
- Add Tony Lindgren acked tag.

Changes in v2:
- Remove SSC registers from dpll_core_ck@490 node (SSC is not supported)
- Add SSC registers to dpll_mpu_ck@488 node.
