clk: qcom: clk-smd-rpm: Fix the reported rate of branches

2017-07-18T01:22:30+00:00

As there is no way to actually query the hardware for the current clock rate, now racalc_rate() just returns the last rate that was previously set. But if the rate was not set yet, we return the bogus rate of 1000Hz. The branch clocks have the same rate as their parent, so in this case we just need to remove recalc_rate ops and then the core framework will handle this automagically. The round_rate() is unused, so remove it as well.

clk: qcom: Add support for SMD-RPM Clocks

2016-11-11T00:37:55+00:00

This adds initial support for clocks controlled by the Resource Power Manager (RPM) processor on some Qualcomm SoCs, which use the qcom_smd_rpm driver to communicate with RPM. Such platforms are msm8916, apq8084 and msm8974. The RPM is a dedicated hardware engine for managing the shared SoC resources in order to keep the lowest power profile. It communicates with other hardware subsystems via shared memory and accepts clock requests, aggregates the requests and turns the clocks on/off or scales them on demand. This driver is based on the codeaurora.org driver: https://www.codeaurora.org/cgit/quic/la/kernel/msm-3.10/tree/drivers/clk/qcom/clock-rpm.c Signed-off-by: Georgi Djakov Acked-by: Rob Herring [sboyd@codeaurora.org: Remove useless braces for single line if] Signed-off-by: Stephen Boyd
