Subject: [v3,1/2] dt-bindings: rtc: pcf85263/pcf85363: add some properties
Date:   Tue,  3 Sep 2019 14:18:52 +0800
Message-Id: <20190903061853.19793-1-biwen.li@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

Add some properties for pcf85263/pcf85363 as follows:
  - interrupt-output-pin: string type
  - quartz-load-femtofarads: integer type
  - nxp,quartz-drive-strength: integer type
  - nxp,quartz-low-jitter: bool type
  - wakeup-source: bool type

Change in v3:
	- None

Change in v2:
	- Replace properties name
	  quartz-load-capacitance -> quartz-load-femtofarads
	  quartz-drive-strength -> nxp,quartz-drive-strength
	  quartz-low-jitter -> nxp,quartz-low-jitter
	- Replace drive strength name
	  PCF85263_QUARTZDRIVE_NORMAL -> PCF85263_QUARTZDRIVE_100ko
	  PCF85263_QUARTZDRIVE_LOW -> PCF85263_QUARTZDRIVE_60ko
	  PCF85263_QUARTZDRIVE_HIGH -> PCF85263_QUARTZDRIVE_500ko
	- Set default interrupt-output-pin as "INTA"

 Optional properties:
 - interrupts: IRQ line for the RTC (not implemented).
 
+- interrupt-output-pin: The interrupt output pin must be
+  "INTA" or "INTB", default value is "INTA"
+
+- quartz-load-femtofarads: The internal capacitor to select for the quartz:
+	PCF85263_QUARTZCAP_7pF		[0]
+	PCF85263_QUARTZCAP_6pF		[1]
+	PCF85263_QUARTZCAP_12p5pF	[2] DEFAULT

+	PCF85263_QUARTZDRIVE_60ko	[1]
+	PCF85263_QUARTZDRIVE_500ko	[2]
+
+- nxp,quartz-low-jitter: Boolean property, if present enables low jitter mode
+  which reduces jitter at the cost of increased power consumption.
+
+- wakeup-source: Boolean property, Please refer to
+  Documentation/devicetree/bindings/power/wakeup-source.txt

 Example:
