> Commit d31fd43c0f9a ("clk: x86: Do not gate clocks enabled by the
> firmware") causes all unclaimed PMC clocks on Cherry Trail devices to be on
> all the time, resulting on the device not being able to reach S0i2 or S0i3
> when suspended.
>
> The reason for this commit is that on some Bay Trail / Cherry Trail devices
> the ethernet controller uses pmc_plt_clk_4. This commit adds an "ether_clk"
> alias, so that the relevant ethernet drivers can try to (optionally) use
> this, without needing X86 specific code / hacks, thus fixing ethernet on
> these devices without breaking S0i3 support.
>
> This commit uses clkdev_hw_create() to create the alias, mirroring the code
> for the already existing "mclk" alias for pmc_plt_clk_3.
