Subject: [PATCH v5 4/5] Documentation: atmel-pmc: add DT bindings for fast startup
Date: Wed, 16 Mar 2016 14:58:08 +0800 [thread overview]
Message-ID: <1458111489-23774-5-git-send-email-wenyou.yang@atmel.com> (raw)
In-Reply-To: <1458111489-23774-1-git-send-email-wenyou.yang@atmel.com>
Add DT bindings to configurate the PMC_FSMR and PMC_FSPR registers
to trigger a fast restart signal to PMC.
Signed-off-by: Wenyou Yang <wenyou.yang@atmel.com>
Acked-by: Rob Herring <robh+dt@kernel.org>
---
Changes in v5:
- due to the DT property expression change, update the binding
document.
Changes in v4:
- add Acked-by tag.
Changes in v3:
- update the property description.
Changes in v2:
- change the property name and property description.

+PMC Fast Startup Signals
+
+The PMC Fast Start Signals are used as the wake up source to trigger the PMC
+to wake up the system from the ULP1 mode.
+
+required properties:
+- compatible: should be "atmel,sama5d2-pmc-fast-startup".
+
+optional properties:
+- atmel,wakeup-rtc-timer: boolean to enable RTC alarm wake-up.
+- atmel,wakeup-usb-resume: boolean to enable USB resume wake-up.
+- atmel,wakeup-sdmmc-cd: boolean to enable SDMMC card detect wake-up.
+- atmel,wakeup-rxlp-match: boolean to enable RXLP matching condition wake-up.
+- atmel,wakeup-acc-comparison: boolean to enable ACC comparison wake-up.
+
+The node contains child nodes for each wake-up input pin that the platform uses.
+
+Input nodes
+
+Required properties:
+- reg: should contain the wake-up input index [0 - 10], to enable
+ the corresponding wake-up input.
+
+Optional properties:
+- atmel,wakeup-active-high: boolean to declare the corresponding wake-up
+ input described by the child be active high.
+ The default is to be active low.
+
+Example:
+
+ pmc: pmc@f0014000 {
+ compatible = "atmel,sama5d2-pmc";
+ reg = <0xf0014000 0x160>;
+
+ pmc_fast_restart {
+ compatible = "atmel,sama5d2-pmc-fast-startup";
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ atmel,wakeup-rtc-timer;
+
+ wkpin: input@0 {
+ reg = <0>;
+ };
+
+ gmac_wol: input@10 {
+ reg = <10>;
+ atmel,wakeup-active-high;
+ };
+ };
+ };
