[PATCH v5 3/9] clk: qcom: apss-ipq-pll: Use stromer plus ops for stromer plus pll
Posted by Varadarajan Narayanan 2 years, 1 month ago
The set rate and determine rate operations are different between
Stromer and Stromer Plus PLLs. Since the programming sequence is
different, the PLLs dont get configured properly and random,
inexplicable crash/freeze is seen. Hence, use stromer plus ops
for ipq_pll_stromer_plus.
