HHI_MPLL_CNTL8 and HHI_MPLL_CNTL9 default to zero. On all GX SoCs these
seem to be initialized by the bootloader to some default value.
However, on my Meson8 board they are not initialized, leading to a
division by zero in rate_from_params as the math is:
(parent_rate * SDM_DEN) / ((SDM_DEN * 0) + 0)
According to the datasheet, the minimum n2 value is 4. The rate provided
by the clock when n2 is less than this minimum is unpredictable. In such
case, we report an error.

clk: tegra: Don't reset PLL-CX if it is already enabled
Commit
8dce89a1c2cf ("clk: tegra: Don't warn for PLL defaults
unnecessarily") changed the tegra210_pllcx_set_defaults() function
causing the PLL to always be reset regardless of whether it is in-use.
This function was changed so that resetting of the PLL will only be
skipped if the PLL is enabled AND 'pllcx->params->defaults_set' is not
true. However, the 'pllcx->params->defaults_set' is always true and
hence, the PLL is now always reset. This causes the boot to fail on the
Tegra210 Smaug where the PLL is already enabled and in-use. Fix this by
only resetting the PLL if not in-use and only printing the warning that
the defaults are not set after we have checked the default settings.

clk: renesas: r8a7795: Add support for R-Car H3 ES2.0
The Clock Pulse Generator / Module Standby and Software Reset module in
R-Car H3 ES2.0 differs from ES1.x in the following areas:
- More core clocks (S0D2, S0D3, S0D6, S0D8, S0D12),
- Different parent clocks for AUDMAC, EtherAVB, FCP, FDP, IMR,
SYS-DMAC, VIN, VSPB, VSPI,
- Removal of modules CSI21, FCPCI, FCPF2, FCPVD3, FCPVI2, FDP1-2,
USB3-IF1, VSPD3, VSPI2,
- Addition of modules EHCI3, HS-USB-IF3, USB-DMAC3-0, USB-DMAC3-1.
The goal is twofold:
1. Support both the ES1.x and ES2.0 SoC revisions in a single binary
for now,
2. Make it clear which code supports ES1.x, so it can easily be
identified and removed later, when production SoCs are deemed
ubiquitous.
This is achieved by:
- Updating the clock tables for the latest revision (ES2.0), but not
removing clocks that only exist on earlier revisions (ES1.x),
- Detecting the SoC revision at runtime using the new soc_device_match()
API, and fixing up the clocks tables to match the actual SoC
revision, by:
- NULLifying core and module clocks of modules that do not exist,
- Reparenting module clocks that have a different parent on ES1.x.

The same SoC may have different clocks and/or module clock parents,
depending on SoC revision. One option is to use different sets of clock
tables for each SoC revision. However, if the differences are small, it
is much more space-efficient to have a single set of clock tables, and
fix those up at runtime instead.
Hence provide three helpers:
- Two helpers to NULLify core and module clocks that do not exist on
some revisions (NULLified clocks are skipped during the registration
phase),
- One helper to reparent module clocks that have different clock
parents.

clk: sunxi-ng: fix recalc_rate formula of NKMP clocks
In commit
e66f81bbd746 ("clk: sunxi-ng: Implement factors offsets"), the
final formula of NKMP clocks' recalc_rate is refactored; however, the
refactored formula broke the calculation due to some C language operand
priority problem -- the priority of operand >> is lower than * and /,
makes the formula being parsed as "(parent_rate * n * k) >> (p / m)", but
it should be "(parent_rate * n * k >> p) / m".
Add the pair of parentheses to fix up this issue. This pair of
parentheses used to exist in the old formula.
Fixes:

Timer-Ids were unused both in clock-driver as well as devicetree

clk: ti: convert to use proper register definition for all accesses
Currently, TI clock driver uses an encapsulated struct that is cast into
a void pointer to store all register addresses. This can be considered
as rather nasty hackery, and prevents from expanding the register
address field also. Instead, replace all the code to use proper struct
in place for this, which contains all the previously used data.
This patch is rather large as it is touching multiple files, but this
can't be split up as we need to avoid any boot breakage.
