Subject: [PATCH v2 5/7] arm64: dts: hisilicon: poplar: Standardize LED labels and triggers
Date:   Mon, 29 Oct 2018 14:30:04 +0530
Message-Id: <20181029090006.4353-6-manivannan.sadhasivam@linaro.org>
In-Reply-To: <20181029090006.4353-1-manivannan.sadhasivam@linaro.org>
References: <20181029090006.4353-1-manivannan.sadhasivam@linaro.org>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

For all 96Boards, the following standard is used for onboard LEDs.

green:user1  default-trigger: heartbeat
green:user2  default-trigger: mmc0/disk-activity(onboard-storage)
green:user3  default-trigger: mmc1 (SD-card)
green:user4  default-trigger: none, panic-indicator
yellow:wlan  default-trigger: phy0tx
blue:bt      default-trigger: hci0-power

So lets adopt the same for Poplar, which is one of the 96Boards
Enterprise edition platform.

Due to absence of WLAN and BT support, corresponding LED nodes are not
considered.
