Subject: [PATCH] clk: qcom: dispcc-sm8250: Add additional parent clocks for DP
Date: Wed, 21 Jul 2021 15:46:10 -0700 [thread overview]
Message-ID: <20210721224610.3035258-1-bjorn.andersson@linaro.org> (raw)
The clock controller has two additional clock source pairs, in order to
support more than a single DisplayPort PHY. List these, so it's possible
to describe them all.
Also drop the unnecessary freq_tbl for the link clock sources, to allow
these parents to be used.
