From mboxrd@z Thu Jan 1 00:00:00 1970 From: georgi.djakov@linaro.org (Georgi Djakov) Date: Mon, 9 Jul 2018 18:51:03 +0300 Subject: [PATCH v6 7/8] dt-bindings: Introduce interconnect consumers bindings In-Reply-To: <20180709155104.25528-1-georgi.djakov@linaro.org> References: <20180709155104.25528-1-georgi.djakov@linaro.org> Message-ID: <20180709155104.25528-8-georgi.djakov@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org Add documentation for the interconnect consumer bindings, that will allow to link a device node (consumer) to its interconnect controller hardware. Tha aim is to enable drivers to request a framework API to configure an interconnect path by providing their struct device pointer and a name.
