44c78aa7ac clk: renesas: Handle R8A779A0 V3U clock types in Gen3 clock code
On R8A779A0 V3U SoC, PLL1 and PLL5 use a divider value
from cpg_pll_configs table while PLL{20,21,30,31,4} use
different control offset. Introduce new types to handle
this and handle those types in the Gen3 clock code.

e7690e6195 clk: renesas: Deduplicate gen3_clk_get_rate64() PLL handling
Most of the PLLx, MAIN, FIXED clock handlers are calling very similar
code, which determines parent rate and then applies multiplication and
division. The only difference is whether multiplication is fixed factor
or coming from CRx register. Deduplicate the code into a single function.

3934b41bb4 clk: renesas: Only ever access documented bits in clock driver teardown
The clock driver used a heavy-handed approach where it turned off
all available clocks, while also possibly setting bits which are not
documented in the R-Car datasheet. Update the tables so that only
the bits which are documented are set or cleared when tearing down
the clock driver.

Note that the only clock left running before booting Linux are now
MFIC, INTC-AP, INTC-EX and SCIF2 / SCIF0 on V3x.

401d1c4f5d common: Drop asm/global_data.h from common header
Move this out of the common header and include it only where needed.  In
a number of cases this requires adding "struct udevice;" to avoid adding
another large header or in other cases replacing / adding missing header
files that had been pulled in, very indirectly.   Finally, we have a few
cases where we did not need to include <asm/global_data.h> at all, so
remove that include.

41575d8e4c dm: treewide: Rename auto_alloc_size members to be shorter
This construct is quite long-winded. In earlier days it made some sense
since auto-allocation was a strange concept. But with driver model now
used pretty universally, we can shorten this to 'auto'. This reduces
verbosity and makes it easier to read.

Coincidentally it also ensures that every declaration is on one line,
thus making dtoc's job easier.

8613c8d897 treewide: convert (void *)devfdt_get_addr() to dev_read_addr_ptr()
Use the _ptr suffixed variant instead of casting. Also, convert it to
dev_read_addr_ptr(), which is safe to CONFIG_OF_LIVE.

One curious part is an error check like follows in
drivers/watchdog/omap_wdt.c:

    priv->regs = (struct wd_timer *)devfdt_get_addr(dev);
    if (!priv->regs)
            return -EINVAL;

devfdt_get_addr() returns FDT_ADDR_T_NONE (i.e. -1) on error.
So, this code does not catch any error in DT parsing.

dev_read_addr_ptr() returns NULL on error, so this error check
will work.

I generated this commit by the following command:

 $ find . -name .git -prune -o -name '*.[ch]' -type f -print | \
   xargs sed -i -e 's/([^*)]*\*)devfdt_get_addr(/dev_read_addr_ptr(/'

The fdtdec_get_addr() does not take into account values set in #address-cells

fdtdec_get_addr_size_auto_noparent(), which takes the #address/size-cells
values into consideration, otherwise the reset controller node register

83d290c56f SPDX: Convert all of our single license tags to Linux Kernel style
When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

The initconst is not used in U-Boot, drop it. The r8a7794_crit_mod_clks
is also not used in U-Boot, so drop it too.
