[PATCH v3] MIPS: pm-cps: Block system suspend when a JTAG probe is present

2018-02-20 Thread Matt Redfearn
If a JTAG probe is connected to a MIPS cluster, then the CPC detects it and latches the CPC.STAT_CONF.EJTAG_PROBE bit to 1. While set, attempting to send a power-down command to a core will be blocked, and the CPC will instead send the core to clock-off state. This can interfere with systems fully
