clk: qcom: Put venus core0/1 gdscs to hw control mode

2016-11-24T00:41:19+00:00

The venus video ip's internal core blocks are under the control of the firmware and their powerdomains needs to be 'ON' only when used by the firmware. So putting it into hw controlled mode lets this to happen, otherwise the firmware hangs checking for this. Signed-off-by: Sricharan R Signed-off-by: Stephen Boyd

clk: qcom: gdsc: Add support for gdscs with HW control

2016-11-24T00:41:15+00:00

Some GDSCs might support a HW control mode, where in the power domain (gdsc) is brought in and out of low power state (while unsued) without any SW assistance, saving power. Such GDSCs can be configured in a HW control mode when powered on until they are explicitly requested to be powered off by software.

clk: qcom: clk-rpm: Fix clk_hw references

2016-11-23T19:12:48+00:00

Fix the clk_hw references to the actual clocks and add a xlate function to return the hw pointers from the already existing static array. Reported-by: Michael Scott Signed-off-by: Georgi Djakov Signed-off-by: Stephen Boyd

clk: qcom: Move all sdcc rcgs to use clk_rcg2_floor_ops

2016-11-23T19:00:06+00:00

The sdcc driver for msm8996/msm8916/msm8974/msm8994 and apq8084 expects a clk_set_rate() on the sdcc rcg clk to set a floor value of supported clk rate closest to the requested rate, by looking up the frequency table. So move all the sdcc rcgs on all these platforms to use the newly introduced clk_rcg2_floor_ops Signed-off-by: Rajendra Nayak Signed-off-by: Ritesh Harjani Signed-off-by: Jeremy McNicoll Signed-off-by: Stephen Boyd

clk: qcom: Add rcg ops to return floor value closest to the requested rate

2016-11-23T19:00:05+00:00

The default behaviour with clk_rcg2_ops is for the clk_round_rate()/clk_set_rate() to return/set a ceil clock rate closest to the requested rate by looking up the corresponding frequency table. However, we do have some instances (mainly sdcc on various platforms) of clients expecting a clk_set_rate() to set a floor value instead. Add a new clk_rcg2_floor_ops to handle this for such specific rcg instances Signed-off-by: Rajendra Nayak Signed-off-by: Ritesh Harjani Signed-off-by: Stephen Boyd

clk: qcom: Add support for RPM Clocks

2016-11-11T00:46:56+00:00

This adds initial support for clocks controlled by the Resource Power Manager (RPM) processor on some Qualcomm SoCs, which use the qcom_rpm driver to communicate with RPM. Such platforms are apq8064 and msm8960. Signed-off-by: Georgi Djakov Acked-by: Rob Herring Signed-off-by: Stephen Boyd

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

clk: qcom: Always add factor clock for xo clocks

2016-11-11T00:36:19+00:00

Currently the RPM/RPM-SMD clock drivers do not register the xo clocks, so we should always add factor clock. When we later add xo clocks support into the drivers, we should update this function to skip registration. By doing so we avoid any DT dependencies.
