Do not cache the single CPG MODE register bit 12, instead cache the
entire register value, and only pick the matching bit from the cached
value when core clock of type MDSEL or PE are used. Both MDSEL and PE
clock type currently define .offset field as 12 on Gen3, which means
this code will use bit 12 on Gen3 again, however there are additional
clock on Gen4 which use different bits, and having this flexibility

The CLK_RCAR_GEN3 registers two subdrivers, clk_gen3 and rst_gen3.
The former depends on the clock framework, which is always enabled
in this context of clock framework driver, while the later depends
on reset framework which may not always be enabled.
Ensure the reset framework is also always enabled to prevent inobvious
early boot time bind failure of the CPG driver, which leads to system
showing no activity and is difficult to debug.
Note that one possible approach to debug this is to use CONFIG_DEBUG_UART
and add debug printascii()s into the drivers/clk/renesas/clk-rcar-gen3.c .

frequency clock and later devicetrees handled this properly. Check the
devicetree & if it is one of the fixed ones, register the msspll.
Otherwise, skip registering it & pass the reference clock directly to
the cfg clock registration function so that existing devicetrees are
not broken by this change.
As the MSS PLL is not a "cfg" or a "periph" clock, add a new driver for
it, based on the one in Linux.

Currently the clock driver for PolarFire SoC takes a very naive approach
to the relationship between clocks. It reads the dt to get an input
clock, assumes that that is fixed frequency, reads the "clock-frequency"
property & uses that to set up both the "cfg" and "periph" clocks.
Simplifying for the sake of incremental fixes, the "correct" parentage for
the clocks currently supported in U-Boot is that the "cfg" clocks should
be children of the fixed frequency clock in the dt. The AHB clock is one
of these "cfg" clocks and is the parent of the "periph" clocks.
Instead of passing the clock rate of the fixed-frequency clock to the
"cfg" and "periph" registration functions and the name of the parents,
pass their actual parents & use clk_get_rate() to determine their parents
rates.
The "periph" clocks are purely gate clocks and should not be reading the
AHB clocks registers to determine their rates, as they can simply report
the output of clk_get_rate() on their parent.

All functions getting and setting clock rate use ulong for rate, only
clk_get_parent_rate is an exception. Change the return value to match
other clock rate funcrions.
Most users directly assign the rate to unsigned long anyway, and the few
users that use u64 (not s64) multiply the rate so they may need the
extra bits for the result in their use case.

The original code set up the DDR clock to 48 MHz, not 50MHz as
requested, and did it in a way that didn't satisfy the Application
Notes in RK3399 TRM [1]. 2.9.2.B says:
PLL frequency range requirement
[...]
FOUTVCO: 800MHz to 3.2GHz
2.9.2.A :
PLL output frequency configuration
[...]
FOUTVCO = FREF / REFDIV * FBDIV
FOUTPOSTDIV = FOUTVCO / POSTDIV1 / POSTDIV2
FREF = 24 MHz
The original code gives FOUTVCO: 24MHz/1 * 12 = 288MHz < 800MHz
And the resulting FOUTPOSTDIV is 288MHz / 3 / 2 = 48MHz
but the requested frequency was 50MHz
Note:
2.7.2 Detail Register Description
PMUCRU_PPLL_CON0 says
fbdiv
Feedback Divide Value
Valid divider settings are:
[16, 3200] in integer mode
So .fbdiv = 12 wouldn't be right. But 2.9.2.C says:
PLL setting consideration
[...]
The following settings are valid for FBDIV:
DSMPD=1 (Integer Mode):
12,13,14,16-4095 (practical value is limited to 3200, 2400, or 1600
(FVCOMAX / FREFMIN))
[...]
So .fbdiv = 12 would be right.
In any case FOUTVCO is still wrong. I thank YouMin Chen for
confirmation and explanation.
Despite documentation, I don't seem to be able to reproduce a
practical problem with the wrong FOUTVCO. When I initially found it I
thought some problems with detecting the RAM capacity in my Rock Pi 4B
could be related to it and my patch seemed to help. But since I'm no
longer able to reproduce the issue, it works with or without this
patch. And meanwhile a patch[2] by Lee Jones and YouMin Chen addresses
this issue. Btw, shouldn't that be commited?
So this patches solves no visible problem. Yet, to prevent future
problems, I think it'd be best to stick to spec.
An alternative to this patch could be
{.refdiv = 1, .fbdiv = 75, .postdiv1 = 6, .postdiv2 = 6};
This would theoretically consume more power and yield less jitter,
according to 2.9.2.C :
PLL setting consideration
[...]
For lowest power operation, the minimum VCO and FREF frequencies
should be used. For minimum jitter operation, the highest VCO and
FREF frequencies should be used.
[...]
But I haven't tried it because I don't think it matters much. 50MHz
for DDR is only shortly used by TPL at RAM init. Normal operation is
at 800MHz. Maybe it's better to use less power until later when more
complex software can control batteries or charging or whatever ?

The mtk clock framework in u-boot uses array index for searching clock
parent (kernel uses strings for search), so we need to specify a special
clock with ID=0 for CLK_XTAL in u-boot.
In the mt7622/mt7629 clock tree, the clocks with ID=0 never call
mtk_topckgen_get_mux_rate, adn return xtal clock directly. This what we
expected.
However for newer chips, they may have some clocks with ID=0 not
representing the xtal clock and still needs mtk_topckgen_get_mux_rate be
called. Current logic will make entire clock driver not working.
This patch adds a flag to indicate that whether a clock driver needs clocks
with ID=0 to call mtk_topckgen_get_mux_rate.

Because the gate arrays are not given explicit sizes, the arrays are
only as large as the highest-numbered gate described in the driver.
However, only a subset of the CCU clocks are needed by U-Boot. So there
are valid clock specifiers with indexes greater than the size of the
arrays. Referencing any of these clocks causes out-of-bounds access.
Fix this by checking the identifier against the size of the array.

Some devices enumerate various clocks in their DT, and many drivers
just blanketly try to enable all of them. This creates problems
since we only model a few gate clocks, and the clock driver outputs
a warning when a clock is not described:
=========
sunxi_set_gate: (CLK#3) unhandled
=========
Some clocks don't have an enable bit, or are already enabled in a
different way, so we might want to just ignore them.
Add a CCU_CLK_F_DUMMY_GATE flag that indicates that case, and define
a GATE_DUMMY macro that can be used in the clock description array.
Define a few clocks, used by some pinctrl devices, that way to suppress
the runtime warnings.

The introduction of the DM pinctrl driver made its probe function enable
all clocks enumerated in the DT. This includes the "CLK_BUS_PIO" (and
variations) gate clock. Also CLK_PLL_PERIPH0 is used by the R_CCU device.
So far we didn't describe those clocks in our clock driver.
As we enable them already in the SPL, the devices happen to work, but
the clock driver still complains about not finding those clocks:
=========
sunxi_set_gate: (CLK#58) unhandled
=========
Add the one-liners that are needed to announce the gate bit for those
clocks, to silence that message on the console.

Add the clock driver for the rk3066 platform.
Derived from the rk3288 and rk3188 driver it
supports only a bare minimum to bring up the system

SDRAM clock configuration.
The boot devices NAND, EMMC, SDMMC, SPI.
A UART for the debug messages (fixed) at 115200n8.
A SARADC for the recovery button.
A TIMER for the delays (fixed).
There's support for two possible frequencies,
the safe 600MHz which will work with default pmic settings and
will be set to get away from the 24MHz default and
the maximum of 1.416Ghz, which boards can set if they
were able to get pmic support for it.
After the clock tree is set during the TPL probe
there's no parent update support.
In OF_REAL mode the drivers ns16550.c and dw-apb-timer.c
obtain the (fixed) clk_get_rate from the clock driver
instead of platdata.

In order to finish moving this symbol to Kconfig for all platforms, we

CONFIG_DYNAMIC_DDR_CLK_FREQ and populate clock_legacy.h. This entails
also switching all users from CONFIG_SYS_CLK_FREQ to get_board_sys_clk()
and updating a few preprocessor tests.
With that done, all platforms that define a value here can be converted
to Kconfig, and a fall-back of zero is sufficiently safe to use (and
what is used today in cases where code may or may not have this
available). Make sure that code which calls this function includes

The bulk of it is Samuel's DM_I2C rework, which removes the nasty I2C
deprecation warnings for most 32-bit boards. It also includes some
smaller refactorings that pave the way for more changes, mostly driven
by needing to support the Allwinner RISC-V SoC later on.
Board wise we gain support for the FriendlyARM NanoPi R1S H5 router
board and official Pinetab support.
Build-tested for all 160 sunxi boards, and boot tested on a A64, A20,
H3, H6, and H616 board. USB, SD card, eMMC, and Ethernet all work there
(where applicable).
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 clk_ti_am3_dpll_round_rate() 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.

The PLL functions take ulong arguments for rate, but still check if that
rate is negative (which is never true). The correct way to handle this is
to use IS_ERR_VALUE (like is already done in k210_clk_set_rate). While
we're at it, we can move the error checking up into the caller of the pll
set/get rate functions. This also protects our other calculations from
using bogus values for rate.

This adds support for setting clock rates, which was left out of the
initial CCF expunging. There are several tricky bits here, mostly related
to the PLLS:
* The PLL's bypass is broken. If the PLL is reconfigured, any child clocks
will be stopped.
* PLL0 is the parent of ACLK which is the CPU and SRAM's clock. To prevent
stopping the CPU while we configure PLL0's rate, ACLK is reparented
to IN0 while PLL0 is disabled.
* PLL1 is the parent of the AISRAM clock. This clock cannot be reparented,
so we instead just disallow changing PLL1's rate after relocation (when
we are using the AISRAM).

This is effectively a complete rewrite to remove all dependency on CCF.
The code is now smaller, and so is the binary. It also takes up less memory
at runtime (since we don't have to create 40 udevices). In general, I am
much happier with this driver as much of the complexity and late binding
has been removed.
The k210_*_params structs which were previously used to initialize CCF
clocks are now used as the complete configuration. Since we can write our
own division logic, we can now do away with several "half" clocks which
only existed to provide constant factors of two.
The clock IDs have been renumbered to remove unused clocks. This may not be
the last time they are renumbered, since we have diverged with Linux. There
are also still a few clocks left out which may need to be added back in.
In general, I have tried to leave out behavioral changes. However, there is
a small bugfix regarding ACLK. According to the technical reference manual,
its mux comes *after* its divider (which is present only for PLL0). This
would have required yet another intermediate clock to fix with CCF, but
with the new driver it is just 2 lines of code :)

Since 291da96b8e ("clk: Allow clock defaults to be set during re-reloc
state for SPL only") it has been impossible to set clock defaults before
relocation. This is annoying on boards without SPL, since there is no way
to set clock defaults before U-Boot proper. In particular, the aisram rate
must be changed before relocation on the K210, since U-Boot will hang if we
try and change the rate while we are using aisram.
To get around this, extend the stage parameter to allow force setting
defaults, even if they would be otherwise postponed for later. A device
tree property was decided against because of the concerns in the original
commit thread about the overhead of repeatedly parsing the device tree.
