2018-12-28clk: imx8qxp: make the name of clock ID genericAisheng Dong
SCU clock can be used in a similar way by IMX8QXP and IMX8QM SoCs. Let's make the name of clock ID generic to allow other SoCs to reuse the common part. This patch only changes the clock id name and file name, so no functional change.

2018-12-14clk: imx: imx7ulp: add arm hsrun mode clocks supportAnson Huang
i.MX7ULP has a Cortex-A7 CPU which can run in RUN mode or HSRUN mode, it is controlled in SMC1 module. The RUN mode and HSRUN mode will use different clock source for ARM, "divcore" for RUN mode and "hsrun_divcore" for HSRUN mode, so the control bits in SMC1 module can be abstracted as a HW clock mux, this patch adds HSRUN mode related clocks in SCG1 module and adds "arm" clock in SMC1 module to support RUN mode and HSRUN mode switch.

* clk-of: clk: Use of_node_name_eq for node name comparisons
2018-12-14clk: Use of_node_name_eq for node name comparisonsRob Herring
Convert string compares of DT node names to use of_node_name_eq helper instead. This removes direct access to the node name pointer. For instances using of_node_cmp, this has the side effect of now using case sensitive comparisons. This should not matter for any FDT based system which all of these are.

gcc_lpass_trig_clk is not used downstream, therefore there is no reason to expect it to be needed for clients.

Similar to other qcom targets, gcc_mmss_noc_cfg_ahb_clk should not be disabled. Any mmss access depends on this clock, and its been observed that enabling mmssnoc_axi_rpm_clk with rpmcc results in an implicit access to mmss and will crash the system if gcc_mmss_noc_cfg_ahb_clk is disabled.

2018-12-14clk: tegra30: Use Tegra CPU powergate helper functionJon Hunter
Rather than using the tegra_powergate_is_powered() function for determining if a CPU is powered, use the tegra_pmc_cpu_is_powered() instead which was created to get the CPU power status. Internally tegra_pmc_cpu_is_powered() calls tegra_powergate_is_powered() and so is equivalent. The Tegra30 clock driver is the only public user of tegra_powergate_is_powered() and so by updating the Tegra30 clock driver to use tegra_pmc_cpu_is_powered(), we can then make tegra_powergate_is_powered() a non-public function.

2018-12-14clk: tegra: Fix maximum audio sync clock for Tegra124/210Jon Hunter
The maximum frequency supported for I2S on Tegra124 and Tegra210 is 24.576MHz (as stated in the Tegra TK1 data sheet for Tegra124 and the Jetson TX1 module data sheet for Tegra210). However, the maximum I2S frequency is limited to 24MHz because that is the maximum frequency of the audio sync clock. Increase the maximum audio sync clock frequency to 24.576MHz for Tegra124 and Tegra210 in order to support 24.576MHz for I2S. Update the tegra_clk_register_sync_source() function so that it does not set the initial rate for the sync clocks and use the clock init tables to set the initial rate instead.

2018-12-10clk: imx6q: handle ENET PLL bypassLucas Stach
The ENET PLL is different from the other i.MX6 PLLs, as it has multiple outputs with different post-dividers, which are all bypassed if the single bypass bit is activated. The hardware setup looks something like this: _ refclk-o---PLL---o----DIV1-----| \ | | |M |----OUT1 o-----------------------|_/ | | _ | o----DIV2-----| \ | | |M |----OUT2 o-----------------------|_/ | | _ | `----DIV3-----| \ | |M |----OUT3 `-----------------------|_/ The bypass bit not only bypasses the PLL, but also the attached post-dividers. This would be reasonbly straight forward to model with a single output, or with different bypass bits for each output, but sadly the HW guys decided that it would be good to actuate all 3 muxes with a single bit. So the need to have the PLL bypassed for one of the outputs always affects 2 other (in our model) independent branches of the clock tree. This means the decision to bypass this PLL is a system wide design choice and should not be changed on-the-fly, so we can treat any bapass configuration as static. As such we can just register the post-dividiers with a ratio that reflects the bypass status, which allows us to bypass the PLL without breaking our abstraction model and with it DT stability.

2018-12-10clk: imx6q: optionally get CCM inputs via standard clock handlesLucas Stach
When specifying external clock inputs to the CCM the current code requires the clocks to be in a "clocks" child node of the DT root. This is not really conformant with DT best practices. To avoid the need to deviate from those best practices, allow the clock inputs to be specified via standard clock handles. This is in line with how drivers of the later CCM driver revisions on newer i.MX SoCs handle this. As we can't retroactively change the DT binding, allow this as an option with a fallback to the old way of how this has been handled.

2018-12-10clk: imx6q: reset exclusive gates on initLucas Stach
The exclusive gates may be set up in the wrong way by software running before the clock driver comes up. In that case the exclusive setup is locked in its initial state, as the complementary function can't be activated without disabling the initial setup first. To avoid this lock situation, reset the exclusive gates to the off state and allow the kernel to provide the proper setup.
