The RZ/A1 is different than the other Renesas SOCs because the MSTP
registers are 8-bit instead of 32-bit and if you try writing values as
32-bit nothing happens...meaning this driver never worked for r7s72100.

sound_soc {

cpu {
clocks = <&xxx>;

codec {

};
Current driver in this case uses of_clk_get() for each node, but there
is no devm_of_clk_get() today.
OTOH, the problem of having devm_of_clk_get() is that it encourages the
use of of_clk_get() when clk_get() is more desirable.
Thus, this patch adds new devm_get_clk_from_chile() which explicitly
reads as get a clock from a child node of this device.
By this function, we can also use this type of DT bindings

The broadcom clk driver Kconfig file selects and depends on the
COMMON_CLK_IPROC config for different SoC specific drivers. Let's
simplify this by always selecting the COMMON_CLK_IPROC config,
turning it into a set of library code. We still want to retain
the SoC specific options, so we leave those in place. Since we're
here we also drop COMMON_CLK dependency because that's implicitly
handled by including this file in drivers/clk/Kconfig in the
right place and also make CLK_BCM_KONA default to y on the
architecture it exists for instead of plain default y.

Some peripheral clocks, like the VEC (Video EnCoder) clock need to be set
to a precise rate (in our case 108MHz). With the current implementation,
where peripheral clocks are not allowed to forward rate change requests
to their parents, it is impossible to match this requirement unless the
bootloader has configured things correctly, or a specific rate has been
assigned through the DT (with the assigned-clk-rates property).
Add a new field to struct bcm2835_clock_data to specify which parent
clocks accept rate change propagation, and support set rate propagation
in bcm2835_clock_determine_rate().

The OMAP36xx DPLL5, driving EHCI USB, can be subject to a long-term
frequency drift. The frequency drift magnitude depends on the VCO update
rate, which is inversely proportional to the PLL divider. The kernel
DPLL configuration code results in a high value for the divider, leading
to a long term drift high enough to cause USB transmission errors. In
the worst case the USB PHY's ULPI interface can stop responding,
breaking USB operation completely. This manifests itself on the
Beagleboard xM by the LAN9514 reporting 'Cannot enable port 2. Maybe the
cable is bad?' in the kernel log.
Errata sprz319 advisory 2.1 documents PLL values that minimize the
drift. Use them automatically when DPLL5 is used for USB operation,
which we detect based on the requested clock rate. The clock framework
will still compute the PLL parameters and resulting rate as usual, but
the PLL M and N values will then be overridden. This can result in the
effective clock rate being slightly different than the rate cached by
the clock framework, but won't cause any adverse effect to USB
operation.

frequency table.
However, we do have some instances (mainly sdcc on various platforms)
of clients expecting a clk_set_rate() to set a floor value instead.
Add a new clk_rcg2_floor_ops to handle this for such specific
rcg instances

Unlike clk_register_clkdev(), clk_hw_register_clkdev() doesn't check for
passed error objects from a previous registration call. Hence the caller
of clk_hw_register_*() has to check for errors before calling
clk_hw_register_clkdev*().
Make clk_hw_register_clkdev() more similar to clk_register_clkdev() by
adding this error check, removing the burden from callers that do mass
registration.

The PLL-MIPI clock is somewhat special as it has its own LDOs which
need to be turned on for this PLL to actually work and output a clock
signal.
Add the 2 LDO enable bits to the gate bits. This fixes issues with
the TCON not sending vblank interrupts when the tcon and dot clock are
indirectly clocked from the PLL-MIPI clock.

Some parent clocks of the Exynos5433 CMUs must be always enabled to access
any register in the given CMU or devices connected to it. For the time
being, until a proper solution based on runtime PM is applied, mark those
clocks as critical (instead of ignore unused) to prevent disabling them.
