Subject: [PATCH v3 7/7] arm64: dts: qcom: qrb5165-rb5: add QCA6391 WiFi+BT SoC
Date: Tue, 22 Jun 2021 01:31:41 +0300	[thread overview]
Message-ID: <20210621223141.1638189-8-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20210621223141.1638189-1-dmitry.baryshkov@linaro.org>

Describe the onboard WiFi+BT SoC QCA6391. It is connected to uart6 to
provide Bluetooth functionality (QCA) and to PCIe to provide WiFi
(ath11k). A separate power sequencer device node is used to describe
on-SoC power management unit common to both WiFi and BT parts.
