Subject: [PATCH 6/6] arm64: dts: exynos: add the WiFi/PCIe support to TM2(e) boards
Date: Mon, 19 Oct 2020 11:47:15 +0200 [thread overview]
Message-ID: <20201019094715.15343-7-m.szyprowski@samsung.com> (raw)
In-Reply-To: <20201019094715.15343-1-m.szyprowski@samsung.com>
From: Jaehoon Chung <jh80.chung@samsung.com>
Add the nodes relevant to PCIe PHY and PCIe support. PCIe is used for the
WiFi interface (Broadcom Limited BCM4358 802.11ac Wireless LAN SoC).
