[PATCH v9 7/8] ARM: dts: stm32: add Timers driver for stm32f429 MCU
Benjamin Gaignard

Fri Jan 20 01:15:08 PST 2017
Add Timers and it sub-nodes into DT for stm32f429 family.
version 9:
- re-order timers node per addresses
version 6:
- split patch in two: one for SoC family and one for stm32f469
discovery board.
version 5:
- rename gptimer node to timers
- re-order timers node per addresses
version 4:
- remove unwanted indexing in pwm@ and timer@ node name
- use "reg" instead of additional parameters to set timer
configuration
version 3:
- use "st,stm32-timer-trigger" in DT
version 2:
- use parameters to describe hardware capabilities
- do not use references for pwm and iio timer subnodes
