The only way for a fixed factor clock to change its rate would be to change its parent rate. Since passing blindly CLK_SET_RATE_PARENT might break a lot of platforms that were relying on the fact that the parent rate wouldn't change, introduce a compatible-based whitelist that will allow clocks to opt-in that flag.

Before, there was an ordering issue that the clock provider had been published in hisi_clk_init before it could provide valid clocks to consumers. hisi_clk_alloc is just used to allocate memory space for struct hisi_clock_data. It makes it possible to publish the provider after the clocks are ready. Signed-off-by:

Now that we have clk_hw based provider APIs to register clks, we can get rid of struct clk pointers while registering clks in these drivers, allowing us to move closer to a clear split of consumer and provider clk APIs. Signed-off-by:

The clk notifier symbols are hidden by COMMON_CLK. However on some platforms HAVE_CLK might be set while COMMON_CLK not which leads to compile test build errors like: $ make.cross ARCH=sh drivers/devfreq/tegra-devfreq.c: In function 'tegra_actmon_rate_notify_cb': >> drivers/devfreq/tegra-devfreq.c:391:16: error: 'POST_RATE_CHANGE' undeclared (first use in this function) if (action != POST_RATE_CHANGE) ^ drivers/devfreq/tegra-devfreq.c: In function 'tegra_devfreq_probe': >> drivers/devfreq/tegra-devfreq.c:654:8: error: implicit declaration of function 'clk_notifier_register' [-Werror=implicit-function-declaration] err = clk_notifier_register(tegra->emc_clock, &tegra->rate_change_nb); ^ Export the macros and data type declarations outside of COMMON_CLK ifdef and provide stubs to fix the compile testing.

The gxbb clock controller is the primary clock generation unit for the AmLogic GXBB SoC. It is clocked by a fixed 24MHz xtal, contains several PLLs and the usual post-dividers, muxes, dividers and leaf gates that are fed into various IP blocks in the SoC. Tested-by:

Remove the composite clock registration function and helpers. Replace unnecessary configuration struct with static initialization of the desired clock type. To preserve git bisect this patch also flips the switch and starts using of_clk_add_hw_provider instead of the deprecated meson_clk_register_clks method. As a byproduct clk.c can be deleted.
