In order to finish moving this symbol to Kconfig for all platforms, we
need to do a few more things. First, for all platforms that define this
to a function, introduce CONFIG_DYNAMIC_SYS_CLK_FREQ, similar to
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
<clock_legacy.h> to get the prototype.

Starting with commit 92f1e9a4b3 ("clk: Detect failure to set

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.
