Subject: [PATCHv7 1/9] dt-bindings: omap: add new binding for PRM instances
Date: Tue, 8 Oct 2019 10:19:05 +0300	[thread overview]
Message-ID: <20191008071913.28740-2-t-kristo@ti.com> (raw)
In-Reply-To: <20191008071913.28740-1-t-kristo@ti.com>

Add new binding for OMAP PRM (Power and Reset Manager) instances. Each
of these will act as a power domain controller and potentially as a reset
provider.

+OMAP PRM instance bindings
+
+Power and Reset Manager is an IP block on OMAP family of devices which
+handle the power domains and their current state, and provide reset
+handling for the domains and/or separate IP blocks under the power domain
+hierarchy.
+
+Required properties:
+- compatible:	Must contain one of the following:
+		"ti,am3-prm-inst"
+		"ti,am4-prm-inst"
+		"ti,omap4-prm-inst"
+		"ti,omap5-prm-inst"

+- reg:		Contains PRM instance register address range
+		(base address and length)
+
+Optional properties:
+- #reset-cells:	Should be 1 if the PRM instance in question supports resets.

+Example:
+
+prm_dsp2: prm@1b00 {
