Subject: [PATCH 1013/1013] psci: dont advertise OSI support for IPQ6018
|
|
|
|
Some older IPQ60xx SoC series boards ship with TrustZone/QSEE firmware
|
|
older than TZ.WNS.5.1-00084 which will advertise OSI[1] but are broken
|
|
and trying to use OSI will cause the board to hang until WDT kicks in.
|
|
|
|
So workaround it by checking for SoC compatible and returning false so
|
|
OSI is not used.
