Subject: [PATCH v2 4/4] clk: qcom: dispcc-sm8650: fix DisplayPort clocks
Date: Wed, 24 Apr 2024 04:39:32 +0300 [thread overview]
Message-ID: <20240424-dispcc-dp-clocks-v2-4-b44038f3fa96@linaro.org> (raw)
In-Reply-To: <20240424-dispcc-dp-clocks-v2-0-b44038f3fa96@linaro.org>
On SM8650 DisplayPort link clocks use frequency tables inherited from
the vendor kernel, it is not applicable in the upstream kernel. Drop
frequency tables and use clk_byte2_ops for those clocks.
This fixes frequency selection in the OPP core (which otherwise attempts
to use invalid 810 KHz as DP link rate), also fixing the following
message:
msm-dp-display af54000.displayport-controller: _opp_config_clk_single: failed to set clock rate: -22
Fixes: 9e939f008338 ("clk: qcom: add the SM8650 Display Clock Controller driver")
