Add a new stm32mp25 compatible to stm32-timer dt-bindings in order to support the STM32MP25 SoC. Some features has been added or updated in the stm32-timer timer such as: - hardware configuration and identification registers to read the timer version and capabilities (counter width, number of channels...) - dithering mode (can be used to extend PWM resolution) - input triggers list - new counter modes - various bit-field updates - power-domains property Timer trigger identifier can be up to 19 (from timer 20) Signed-off-by: Fabrice Gasnier <fabrice.gasnier@foss.st.com> --- .../bindings/mfd/st,stm32-timers.yaml | 18 ++++++++++++++---- 1 file changed, 14 insertions(+), 4 deletions(-)
