[PATCH 0/6] Support spread spectrum clocking for stm32f{4,7} platforms

[Dario Binacchi]

The series adds support for spread spectrum clocking for stm32f{4,7}
main PLL.

To achieve this, it was considered necessary to also apply patches to
improve the documentation (conversion of st,stm32-rcc.txt according to
the json-schema) and the code (use of FIELD helpers).

The series has been tested on the STM32F469I-DISCO board.


Dario Binacchi (6):
  dt-bindings: clock: convert stm32 rcc bindings to json-schema
  dt-bindings: reset: st,stm32-rcc: update reference due to rename
  dt-bindings: clock: stm32fx: update reference due to rename
  dt-bindings: clock: st,stm32-rcc: support spread spectrum clocking
  clk: stm32f4: use FIELD helpers to access the PLLCFGR fields
  clk: stm32f4: support spread spectrum clock generation
