The PM action saves the interrupts enabled using a global variable called usart_intenset. The problem is when you have multiple uart instances that have different configurations, when entering/exiting from a power level, only one configuration is saved and will be applied to all uart instances when exiting from a power level. We need to keep this setting individual for each instance. To do this, usart_intenset was added as a new element to mcux_flexcomm_data structure. In this way, each uart instance will keep/restore each own setting. Signed-off-by: Missael Maciel <[email protected]> (cherry picked from commit a84e0b5)
Removed usart_intenset attribute from conditional compilation in mcux_flexcomm_data structure since this parameter needs to be saved/restored independently if the interrupts are enabled or not based on the PR feedback Signed-off-by: Missael Maciel <[email protected]> (cherry picked from commit 726e7b6)
