Subject: [PATCHv3 01/10] dt-bindings: omap: add new binding for PRM instances
Date: Fri, 30 Aug 2019 15:18:07 +0300 [thread overview]
Message-ID: <20190830121816.30034-2-t-kristo@ti.com> (raw)
In-Reply-To: <20190830121816.30034-1-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 be one of:
+ "ti,am3-prm-inst"
+ "ti,am4-prm-inst"
+ "ti,omap4-prm-inst"
+ "ti,omap5-prm-inst"
+ "ti,dra7-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.
+- clocks: Associated clocks for the reset signals if any. Certain reset
+ signals can't be toggled properly without functional clock
+ being active for them.
+
+Example:
+
+prm_dsp2: prm@1b00 {
+ compatible = "ti,dra7-prm-inst";
+ reg = <0x1b00 0x40>;
+ #reset-cells = <1>;
+ clocks = <&dsp2_clkctrl DRA7_DSP2_MMU0_DSP2_CLKCTRL 0>;
+};
