Subject: [PATCH v2 2/5] dt-bindings: ti_sci_pm_domains: Add support for exclusive access
Date: Sat, 23 Feb 2019 15:02:29 +0530	[thread overview]
Message-ID: <20190223093232.29003-3-lokeshvutla@ti.com> (raw)
In-Reply-To: <20190223093232.29003-1-lokeshvutla@ti.com>

TISCI protocol supports for enabling the device with exclusive
permissions. Certain remoteproc devices or some shared devices
across VM doesn't wants to request devices with this flag set.
So add support for getting this information from DT by increasing
the power-domain cells to 2.
