make SPI of STM32MP257 not subject to power domain control

bugman
Associate III

I am currently using the distribution version:

V5、rt 6.1.82-rt patch、stm32mp257

Currently, the SPI interface is bound by default power-domains;

bugman_0-1762235361779.png

I don't want the SPI interface to enter sleep mode during idle time, as it may cause Oops issues

1.How can I prevent it from entering the regulation of this power domain? Do you want to directly delete power domains in the device tree?

2.Once power domains are deleted, will SPI peripherals not enter power consumption adjustment? Or is it in an unknown state?
