Subject: [PATCH 2/2] clk: qcom: mmcc-sdm660: set num_parents on mdss_axi_clk
Date: Mon, 28 Sep 2026 14:41:44 -0300 [thread overview]
Message-ID: <20260928-sdm660-clk-fixes-v1-2-5d5bb84e3258@gmail.com> (raw)
In-Reply-To: <20260928-sdm660-clk-fixes-v1-0-5d5bb84e3258@gmail.com>
From: Fabricio Akio <fabricioakio@gmail.com>
mdss_axi_clk names axi_clk_src in parent_hws but leaves num_parents at
zero, so the array is never read and the branch registers as a root
clock -- no rate of its own, and no reference on its parent:
axi_clk_src en=0 rate=384000000
mdss_axi_clk en=1 rate=0
It is the only branch in this driver missing the field.
Fixes: 5db3ae8b33de ("clk: qcom: Add SDM660 Multimedia Clock Controller (MMCC) driver")
