Subject: [PATCH v3 7/9] soc: samsung: Update the CHIP ID DT binding documentation
Date: Tue, 13 Aug 2019 17:08:25 +0200 [thread overview]
Message-ID: <20190813150827.31972-8-s.nawrocki@samsung.com> (raw)
In-Reply-To: <20190813150827.31972-1-s.nawrocki@samsung.com>
This patch adds documentation of a new optional "samsung,asv-bin"
property in the chipid device node and documents requirement of
"syscon" compatible string. These additions are needed to support
Exynos ASV (Adaptive Supply Voltage) feature.
Signed-off-by: Sylwester Nawrocki <s.nawrocki@samsung.com>

-SAMSUNG Exynos SoCs Chipid driver.
+SAMSUNG Exynos SoC series CHIPID subsystem
Required properties:
-- compatible : Should at least contain "samsung,exynos4210-chipid".
+- compatible : Should at least contain "samsung,exynos4210-chipid", "syscon".
- reg: offset and length of the register set
+Optional properties:
+ - samsung,asv-bin : Adaptive Supply Voltage bin selection. This can be used
+ to determine the ASV bin of an SoC if respective information is missing
+ in the CHIPID registers or in the OTP memory. Possible values: 0...3.
+
Example:
chipid@10000000 {
compatible = "samsung,exynos4210-chipid";
reg = <0x10000000 0x100>;
+ samsung,asv-bin = <2>;
};
