2018-08-20pwm: stm32-lp: Remove useless loop in stm32_pwm_lp_remove()Fabrice Gasnier1-3/+1
LPTimer has only one pwm channel (npwm = 1). Remove useless for loop in remove routine. Signed-off-by: Fabrice Gasnier <fabrice.gasnier@st.com> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
2018-03-28pwm: stm32: LPTimer: Use 3 cells ->of_xlate()Gerald Baeza1-0/+2
STM32 Low-Power Timer supports generic 3 cells PWM to encode PWM number, period and polarity. Signed-off-by: Gerald Baeza <gerald.baeza@st.com> Signed-off-by: Fabrice Gasnier <fabrice.gasnier@st.com> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
