Subject: [PATCH 1/2] dt-bindings: net: snps,dwmac: add snps,rx-clk-runs-in-lpi parameter
Date: Mon, 23 Jan 2023 16:37:46 +0300	[thread overview]
Message-ID: <20230123133747.18896-2-andrey.konovalov@linaro.org> (raw)
In-Reply-To: <20230123133747.18896-1-andrey.konovalov@linaro.org>

This patch adds a new parameter to the stmmac DT: snps,rx-clk-runs-in-lpi.

If this parameter is present in the device tree, the PHY should not stop
RX_CLK after entering Rx LPI state.
