Subject: [PATCH 4.19 423/639] firmware: arm_scmi: update rate_discrete in clock_describe_rates_get

From: Peng Fan <peng.fan@....com>

[ Upstream commit c0759b9b5d411ab27c479125cee9bae391a96436 ]

The boolean rate_discrete needs to be assigned to clk->rate_discrete,
so that clock driver can distinguish between the continuous range and
discrete rates. It uses this in scmi_clk_round_rate could get the
rounded value if it's a continuous range.
