2018-06-01clk-si544: Properly round requested frequency to nearest matchMike Looijmans
The si544 driver had a rounding problem that using the result of clk_round_rate may set the clock to yet another rate, for example: clk_round_rate(195000000) = 194999999 clk_round_rate(194999999) = 194999998 Clients would expect that after clk_set_rate(clk, freq2=clk_round_rate(clk, freq)) the chip will be running at exactly freq2. The problem was in the calculation of the feedback divider, it was always rounded down instead of to the nearest possible VCO value. After this change, the following holds true for any supported frequency: actual_freq = clk_round_rate(clk, freq); clk_set_rate(clk, actual_freq); clk_round_rate(clk, actual_freq) == actual_freq && clk_get_rate(clk) == actual_freq Signed-off-by: Mike Looijmans <mike.looijmans@topic.nl> Fixes: 953cc3e81170 ("clk: Add driver for the si544 clock generator chip") Signed-off-by: Stephen Boyd <sboyd@kernel.org>

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this.

When calling debugfs functions, there is no need to ever check the return value. The function can work or not, but the code logic should never do something different based on this. This cleans up the init code a lot, and there's no need to return an error value based on the debugfs calls, especially as it turns out no one was even looking at that return value.

2018-06-01clk/driver/hisi: Consolidate the Kconfig for the CLOCK_STUBDaniel Lezcano
The current defconfig is inconsistent as it selects the mailbox and the clock for the hi6220 and the hi3660 without having their Kconfigs making sure the dependencies are correct. It ends up when selecting different versions for the kernel (for example when git bisecting) those options disappear and they don't get back, leading to unexpected behaviors. In our case, the cpufreq driver does no longer work because the clock fails to initialize due to the clock stub and the mailbox missing. In order to have the dependencies correctly set when defaulting, let's do the same as commit 3a49afb84ca074e ("clk: enable hi655x common clk automatically") where we select automatically the driver when the parent driver is selected. With sensible defaults in place, we can leave other choices for EXPERT.

The USB and PCIE pipe clocks are sourced from external clocks inside the QMP USB/PCIE PHYs. Enabling or disabling of PIPE RCG clocks is dependent on PHY initialization sequence hence update halt_check to BRANCH_HALT_SKIP for these clocks so that clock status bit is not polled when enabling or disabling the clocks. It allows to simplify PHY client driver code which is both user and source of the pipe_clk and avoid error logging related status check on clk_disable/enable.

2018-06-01clk: qcom: mmcc-msm8996: leave all mmagic gdscs and clocks always enabledRajendra Nayak
There's no bus infrastructure today to handle all the mmagic bus clocks and GDSCs needed by all the multimedia blocks in msm8996, like mdss, video, camera and gpu. Mark all these clocks with a CLK_IS_CRITICAL and GDSCs with a ALWAYS_ON flag for now so they are left always enabled. This patch should be reverted at some point when we do have a bus driver to manage these clocks and GDSCs.

2018-06-01clk: qcom: Register the gdscs before the clocksRajendra Nayak
We have atleast some instances of ALWAYS_ON gdscs, which need to be turned ON *before* some clocks within the gdsc domain marked with a CLK_IS_CRITICAL can be turned ON. To facilitate this sequence, register the GDCSs (and hence handle the ALWAYS_ON gdscs) before we register clocks (and handle the clocks marked as CLK_IS_CRITICAL) Signed-off-by: Rajendra Nayak <rnayak@codeaurora.org> Reviewed-by: Bjorn Andersson <bjorn.andersson@linaro.org> Tested-by: Srinivas Kandagatla <srinivas.kandagatla@linaro.org> Signed-off-by: Stephen Boyd <sboyd@kernel.org>
2018-06-01clk: qcom: gdsc: Add support for ALWAYS_ON gdscsRajendra Nayak
Some GDSCs might have software control to turn them off, but we might want to keep them enabled always, in some cases because of lack of support in kernel to handle a graceful turning off/on of such GDSCs. Most common instances would be the GDCSs which power up the noc/bus fabrics, which need bus drivers to handle them and atleast support for which is missing on all qcom SoCs.

2018-05-30clk: davinci: psc: allow for dev == NULLDavid Lechner
On some davinci SoCs, we need to register the PSC clocks during early boot because they are needed for clocksource/clockevent. These changes allow for dev == NULL because in this case, we won't have a platform device for the clocks.

This modifies the TI Davinci PLL clock driver to allow for the case when dev == NULL. On some (most) SoCs that use this driver, the PLL clock needs to be registered during early boot because it is used for clocksource/clkevent and there will be no platform device available.
