[PATCH v1] dt-bindings: arm: stm32: lxa,stm32mp157c-mc1: add extra SiP compatible

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The Linux Automation MC-1 is built around a SIP with CPU, RAM, PMIC,
Oscillator and EEPROM. Add a further compatible identifying the SiP,
so boot firmware can match against it to apply fixups if necessary.

To avoid intermittent dtbs_check breakage in the sole upstream device
tree that uses that SiP, patch it here as well.

I know that bindings and device tree patches should be separate. Does
this apply here as well? Should I split the dts change into a follow-up
commit? Is it ok that dtbs_check will report an intermittent breakage?
