Subject: [PATCH v2] remoteproc: qcom: q6v5: Use _clk_get_optional for aggre2_clk
Date:   Mon, 18 Jul 2022 15:15:14 +0300
Message-Id: <20220718121514.2451590-1-abel.vesa@linaro.org>

Precedence: bulk

Only msm8996 and msm8998 SLPIs need the RPM_SMD_AGGR2_NOC_CLK
(as aggre2 clock). None of the other platforms do. Back when the support
for the mentioned platforms was added to the q6v5 pass driver, the
devm_clk_get_optional was not available, so the has_aggre2_clk was
necessary in order to differentiate between plaforms that need this
clock and those which do not. Now that devm_clk_get_optional is available,
we can drop the has_aggre2_clk. This makes the adsp_data more cleaner
and removes the check within adsp_init_clocks.
