drivers: i2c: stm32: exclude stm32f7 family for PM in RTIO driver (4217df50) · Commits · Wenxi XU / zephyr

Exclude STM32F7 SoC series from PM support since that SoC doees not yet manage power management in Zephyr and HAL API functions LL_I2C_EnableWakeUpFromStop() and LL_I2C_DisableWakeUpFromStop() are not implemented in the H7 HAL/LL drivers. This change ports into the STM32 RTIO driver the change made in the non-RTIO driver through commit ("drivers: i2c: stm32: exclude stm32f7 family for PM"). Back ported from commit ("drivers: i2c: stm32: exclude stm32f7 family for PM in RTIO driver"). Signed-off-by:
