If the bypass_reg is set, then we can return the bypass parent, however,
if there is not a bypass_reg, we need to figure what the correct parent
mux is.
The previous code never handled the parent mux if there was a
bypass_reg.

The EMAC clocks on Stratix10/Agilex/N5X have an additional bypass that
was not being accounted for. The bypass selects between
emaca_clk/emacb_clk and boot_clk.
Because the bypass register offset is different between Stratix10 and
Agilex/N5X, it's best to create a new function to calculate the bypass.

The purpose of the device-managed functions is to bind the life-time of an
object to that of a parent device object.
This is not the case for the 'vdd-cpu' regulator in this driver. A
reference is obtained via devm_regulator_get() and immediately released
with devm_regulator_put().
In this case, the usage of devm_ functions is slightly excessive, as the
un-managed versions of these functions is a little cleaner (and slightly
more economical in terms of allocation).
This change converts the devm_regulator_{get,put}() to
regulator_{get,put}() in the get_alignment_from_regulator() function of
this driver.

On 5P49V6965, when an output is enabled we enable the corresponding
FOD. When this happens for the first time, and specifically when writing
register VC5_OUT_DIV_CONTROL in vc5_clk_out_prepare(), all other outputs
are stopped for a short time and then restarted.
According to Renesas support this is intended: "The reason for that is VC6E
has synced up all output function".
This behaviour can be disabled at least on VersaClock 6E devices, of which
only the 5P49V6965 is currently implemented by this driver. This requires
writing bit 7 (bypass_sync{1..4}) in register 0x20..0x50. Those registers
are named "Unused Factory Reserved Register", and the bits are documented
as "Skip VDDO<N> verification", which does not clearly explain the relation
to FOD sync. However according to Renesas support as well as my testing
setting this bit does prevent disabling of all clock outputs when enabling
a FOD.

(August 30, 2018), Table 116 "Power Up VDD check", page 58:

The patch enables spread spectrum clocking (SSC) for MPU and LCD PLLs.
As reported by the TI spruh73x/spruhl7x RM, SSC is only supported for
the DISP/LCD and MPU PLLs on am33xx/am43xx. SSC is not supported for
DDR, PER, and CORE PLLs.
Calculating the required values and setting the registers accordingly
was taken from the set_mpu_spreadspectrum routine contained in the
arch/arm/mach-omap2/am33xx/clock_am33xx.c file of the u-boot project.
In locked condition, DPLL output clock = CLKINP *[M/N]. In case of
SSC enabled, the reference manual explains that there is a restriction
of range of M values. Since the omap2_dpll_round_rate routine attempts
to select the minimum possible N, the value of M obtained is not
guaranteed to be within the range required. With the new "ti,min-div"
parameter it is possible to increase N and consequently M to satisfy the
constraint imposed by SSC.

It is now possible to build a modular kernel for vexpress by
not setting CONFIG_ARCH_VEXPRESS=y and instead setting =m on the
drivers that it normally implies. This is with the exception of
CLK_VEXPRESS_OSC which is currently hidden behind a dependency on
one of several ARCH_* variables. Remove that dependency so that
CLK_VEXPRESS_OSC may be enabled without it.

The dev_err_probe() function prints an error message if the error
code is not -EPROBE_DEFER. If we know the error code in is -ENODEV
then there is no reason to check.

dev_err_probe() returns the error code passed as second parameter. Also if
the error code is -EPROBE_DEFER dev_err_probe() is silent, so there is no
need to check for this value before calling dev_err_probe().
