The clk-rpmh driver only supports on and off RPMh clock resources. Let's extend the driver by adding support for clocks that are managed by a different type of RPMh resource known as Bus Clock Manager(BCM). The BCM is a configurable shared resource aggregator that scales performance based on a set of frequency points. The Qualcomm IP Accelerator (IPA) clock is an example of a resource that is managed by the BCM and this a requirement from the IPA driver in order to scale its core clock.

The gcc_usb3_phy_pipe_clk is generated by the phy, but is also used by the phy during init. The clock needs to be enabled during the init sequence, but may not be fully active until after the init sequence is complete. This causes a catch-22 if the clock status is checked during enable. As a result, skip the checks to avoid the troubling situation. Signed-off-by: Jeffrey Hugo <jhugo@codeaurora.org> Signed-off-by: Stephen Boyd <sboyd@kernel.org>

2019-01-09clk: qcom: Add CLK_SET_RATE_PARENT for 8998 branch clocksJeffrey Hugo1-0/+48
A branch clock is basically a clock that can be gated for power savings, but is also what devices/drivers consume. Configuring a branch clock's rate needs to be done at the source, so for all branch clocks which have a defined parent, set CLK_SET_RATE_PARENT so that clk_set_rate() calls on branch clocks can do what is expected. This is important as most drivers do not check the resulting clock rate after a successful clk_set_rate() call, thus the driver may get out of sync with the actual hardware state and weird issues might crop up. This has been observed with issues getting SDHCI to reliably support "fast" cards such as SDR104.

2018-12-03clk: qcom: Add lpass clock controller driver for SDM845Taniya Das4-0/+224
Add support for the lpass clock controller found on SDM845 based devices. This would allow lpass peripheral loader drivers to control the clocks to bring the subsystem out of reset. LPASS clocks present on the global clock controller would be registered with the clock framework based on the protected-clock flag. Also do not gate these clocks if they are left unused, as the lpass clocks require the global clock controller lpass clocks to be enabled before they are accessed. Mark the GCC lpass clocks as CRITICAL, for the LPASS clock access. Signed-off-by: Taniya Das <tdas@codeaurora.org> Signed-off-by: Stephen Boyd <sboyd@kernel.org>

Add SPI friendly clock rates to the spi freq table. Today it's not possible to use SPI at lower than 960Khz. This patch adds 100/250/500/1000 kHz configs to the table. Signed-off-by: Loic Poulain <loic.poulain@linaro.org> Signed-off-by: Stephen Boyd <sboyd@kernel.org>

In an earlier version of commit 453361cdd757 ("clk: qcom: Add graphics clock controller driver for SDM845") there were 6 listed parents for "gpu_cc_gmu_clk_src". In the version that landed there were 5. ...but "num_parents" was still left at 6. On my system this goes boom at bootup.

2018-11-27clk: qcom: Add a dummy enable function for GX gdscJordan Crouse1-0/+26
Most of the time the CPU should not be touching the GX domain on the GPU except for a very special use case when the CPU needs to force the GX headswitch off. Add a dummy enable function for the GX gdsc to simulate success so that the pm_runtime reference counting is correct.

2018-11-21clk: qcom: Support 'protected-clocks' propertyStephen Boyd1-0/+18
Certain firmware configurations "protect" clks and cause the entire system to reboot when a non-secure OS such as Linux tries to read or write protected clk registers. But other firmware configurations allow reading or writing the same registers, and they may actually require that the OS use the otherwise locked down clks. Support the 'protected-clocks' property by never registering these protected clks with the common clk framework. This way, when firmware is protecting these clks we won't have the chance to ever read or write these registers and take down the entire system.
