Subject: [PATCH 5/5] drivers: clk: mediatek: Fix error finding regmap
Date: Mon,  9 Feb 2026 23:37:05 -0600	[thread overview]
Message-ID: <20260210053708.17239-5-aford173@gmail.com> (raw)
In-Reply-To: <20260210053708.17239-1-aford173@gmail.com>

The clock driver for clk-mt8196-vdisp-ao doesn't use the same common clk
functions that other clocks use.  As such, this clock returns an error:

  Cannot find regmap for /soc: -ENOMEM
  clk-mt8196-vdisp-ao 3e800000.syscon: probe with driver clk-mt8196-vdisp-ao failed with error -12

Fix this by using the common clock calls.  With this patch, the following
new clocks properly enumerate:

  mm_v_disp_vdisp_ao_config
  mm_v_disp_dpc
  mm_v_smi_sub_somm0

Fixes: d4fb7e15a520 ("clk: mediatek: Add MT8196 disp-ao clock support")
