Subject: [PATCH v5 1/4] dt-bindings: leds: Add Qualcomm Light Pulse Generator binding
Date: Fri, 16 Oct 2020 22:20:54 -0700 [thread overview]
Message-ID: <20201017052057.2698588-2-bjorn.andersson@linaro.org> (raw)
In-Reply-To: <20201017052057.2698588-1-bjorn.andersson@linaro.org>
This adds the binding document describing the three hardware blocks
related to the Light Pulse Generator found in a wide range of Qualcomm
PMICs.
Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
