Subject: [PATCH v2 01/11] interconnect: icc-rpm: move bus clocks handling into qnoc_probe
Date: Sat, 4 Sep 2021 02:24:11 +0300 [thread overview]
Message-ID: <20210903232421.1384199-2-dmitry.baryshkov@linaro.org> (raw)
In-Reply-To: <20210903232421.1384199-1-dmitry.baryshkov@linaro.org>
All icc-rpm drivers use the same set of bus clocks. Move handling of bus
clocks to qnoc_probe. This both simplifies the code and allows using
qnoc_probe as device's probe funcion.
