Subject: [PATCH 0/3] occ: Restore default behavior of polling OCC during init
Date: Tue, 2 Aug 2022 14:46:53 -0500 [thread overview]
Message-ID: <20220802194656.240564-1-eajames@linux.ibm.com> (raw)
A recent change to the OCC hwmon driver modified the default behavior to
no longer poll the OCC during initialization. This does change the
interface, meaning that old applications will not work with the more
recent driver. To resolve this issue, introduce a new dts property to
control the behavior of the driver during initialization, similar to the
FSI master property "no-scan-on-init". Without the new
"ibm,inactive-on-init" boolean present, the driver will now do the
previous behavior of polling the OCC.

dt-bindings: hwmon: Add IBM OCC bindings
fsi: occ: Support probing the hwmon child device from dts node
hwmon: (occ) Check for device property for setting OCC active during
probe
