2019-02-02clk: meson: axg-audio does not require sysconJerome Brunet
The axg audio clock controller uses regmap mmio, not syscon.

2019-02-02clk: export some clk_hw function symbols for module driversJerome Brunet
clk-provider.h provides clk_hw_is_prepared(), clk_hw_is_enabled() and clk_hw_is_prepared() but these symbols are not exported for the modules which prevents a clock driver using them to be compiled as a module. Export them to fix the problem.

2019-01-07clk: meson: meson8b: add the GPU clock treeMartin Blumenstingl
Add the GPU clock tree on Meson8, Meson8b and Meson8m2. The GPU clock tree on Meson8b and Meson8m2 is almost identical to the one one GXBB: - there's a glitch-free mux at HHI_MALI_CLK_CNTL[31] - there are two identical parents for this mux: mali_0 and mali_1, each with a gate, divider and mux - the parents of mali_0_sel and mali_1_sel are identical to GXBB except there's no GP0_PLL on these 32-bit SoCs Meson8 is different because it does not have the glitch-free mux. Instead if only has the mali_0 clock tree. The parents of mali_0_sel are identical to the ones on Meson8b and Meson8m2.

2019-01-07clk: meson: meson8b: use a separate clock table for Meson8Martin Blumenstingl
The Meson8 SoC is slightly different compared to Meson8b and Meson8m2 because it does not have the glitch-free Mali GPU clock mux. For Meson8b and Meson8m2 there are currently no known differences. Add a separate clk_hw_onecell_data table for Meson8 so these differences can be implemented. For now meson8_hw_onecell_data is a clone of our existing meson8b_hw_onecell_data.

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.

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.

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.

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.

2018-12-14clk: imx: add lpcg clock supportAisheng Dong
The Low-Power Clock Gate (LPCG) modules contain a local programming model to control the clock gates for the peripherals. An LPCG module is used to locally gate the clocks for the associated peripheral. And they're bedind the SCU clock.

Add SCU clock common part which will be used by client clock drivers. SCU clocks are totally different from the legacy clocks (No much legacy things can be reused), it's using a firmware interface now based on SCU protocol. So a new configuration option CONFIG_MXC_CLK_SCU is added.
