Subject: [PATCH 4/5] clk: qcom: a53-pll: Pass freq_tbl via match data
Date: Tue,  4 May 2021 13:28:43 +0800	[thread overview]
Message-ID: <20210504052844.21096-5-shawn.guo@linaro.org> (raw)
In-Reply-To: <20210504052844.21096-1-shawn.guo@linaro.org>

The frequency table is SoC specific.  Instead of hard coding, pass it
via match data, so that the driver can work for more than just MSM8916.
This is a preparation change for adding MSM8939 A53PLL support.
