Luca Weiss	04648b8fad	clk: qcom: clk-hfpll: switch to .determine_rate ... .determine_rate is meant to replace .round_rate. The former comes with a benefit which is especially relevant on 32-bit systems: since .determine_rate uses an "unsigned long" (compared to a "signed long" which is used by .round_rate) the maximum value on 32-bit systems increases from 2^31 (or approx. 2.14GHz) to 2^32 (or approx. 4.29GHz).

Ansuel Smith	fcfbfe373d	clk: qcom: clk-hfpll: use poll_timeout macro ... Use regmap_read_poll_timeout macro instead of do-while structure to tidy things up. Also set a timeout to prevent any sort of system stall.

Jerome Brunet	89d079dc17	clk: let init callback return an error code ... If the init callback is allowed to request resources, it needs a return value to report the outcome of such a request.
