Xing Zheng 09f684226d clk: rockchip: rename rk3228 sclk_macphy_50m to sclk_mac_extclk
The sclk_macphy_50m is confusing, the sclk_mac_extclk describes
a external clock  clearly.

Xing Zheng cb87df58bc clk: rockchip: include rk3228 downstream muxes into fractional dividers
During the initial conversion to the newly introduced combined fractional
dividers+muxes the rk3228 clocks were left out, so convert them now.

We should call iounmap to relase reg_base since it's not going
to be used any more if failing to init clk.

Xing Zheng ef1d9feecc clk: rockchip: Add support for multiple clock providers
There are need to support Multi-CRUs probability in future, but
it is not supported on the current Rockchip Clock Framework.

Therefore, this patch add support a provider as the parameter
handler when we call the clock register functions for per CRU.

Xing Zheng 268aebaa24 clk: rockchip: allow varying mux parameters for cpuclk pll-sources
Thers are only two parent PLLs that APLL and GPLL for core on the
previous SoCs (RK3066/RK3188/RK3288/RK3368). Hence, we set fixed
GPLL as alternate parent when core is switching freq.

Since RK3399 big.LITTLE architecture, we need to select and adapt
more PLLs (ALPLL/ABPLL/DPLL/GPLL) sources.

Heiko Stuebner 36714529f8 clk: rockchip: convert manually created factor clocks to the new type
Clean up the init code and move the creation of factor clocks to the
appropriate positions coming from the clock architecture diagrams.

This also unifies the artificial separation of the hclk_vcodec etc clocks
again.

We do keep the separate definition of some watchdog and usb480m pseudo
clocks for now, as they're not real factor clocks from the clock-tree
but placeholders for fixes to come (usb480m gets supplied by the
missing driver for the new usbphy type and the watchdog-gate is sitting
somewhere else together which we cannot model currently).

mmc sample shift is 0 for rk3228 refer to user manaul.
So it's broken if we enable mmc tuning for rk3228.

Heiko Stuebner dfff24bde7 clk: rockchip: only enter pll slow-mode directly before reboots on rk3288
As commit 1d33929e2a ("clk: rockchip: switch PLLs to slow mode before
reboot for rk3288") states, switching the PLLs to slow-mode is only
necessary when rebooting using the soft-reset done through the CRU.

The dwc2 controllers used create really big number of interrupts in
special constellations involving usb-hubs and their number is so high,
it can even overwhelm the interrupt handler if the cpu-speed os to low.

Right now the PLLs are put into slow-mode in a shutdown syscore_ops
callback which means it happens on all reboots (not only the soft-reset
ones) and even on poweroff actions.

This can result in the system not powering off and getting stuck instead,
so we should move the slow-mode change nearer to the actual reboot action.

For this we introduce the possiblity to also set a callback that gets
called from the restart-handler directly prior to restarting the system
and move the shutdown-callback to this new option.

With this the slow-mode switch is done only on the necessary reboots
and also has a smaller possibility of causing artifacts.
