Until now the clkctrl clocks have been enabled/disabled through platform
routines. Thanks to this patch they can be enabled and configured directly
by the probed devices that need to use them.

The patch adds support for TI gate clock binding. The code is based on
the drivers/clk/ti/gate.c driver of the Linux kernel version 5.9-rc7.

The patch adds support for TI divider clock binding. The driver uses
routines provided by the common clock framework (ccf).
The code is based on the drivers/clk/ti/divider.c driver of the Linux
kernel version 5.9-rc7.

The digital phase-locked loop (DPLL) provides all interface clocks and
functional clocks to the processor of the AM33xx device. The AM33xx
device integrates five different DPLLs:
* Core DPLL
* Per DPLL
* LCD DPLL
* DDR DPLL
* MPU DPLL
The patch adds support for the compatible strings:
* "ti,am3-dpll-core-clock"
* "ti,am3-dpll-no-gate-clock"
* "ti,am3-dpll-no-gate-j-type-clock"
* "ti,am3-dpll-x2-clock"
The code is loosely based on the drivers/clk/ti/dpll.c drivers of the
Linux kernel version 5.9-rc7.

The driver manages a register-mapped multiplexer with multiple input
clock signals or parents, one of which can be selected as output. It
uses routines provided by the common clock framework (ccf).
The code is based on the drivers/clk/ti/mux.c driver of the Linux
kernel version 5.9-rc7.

It returns the rate which will be set if you ask clk_set_rate() to set
that rate. It provides a way to query exactly what rate you'll get if
you call clk_set_rate() with that same argument.
So essentially, clk_round_rate() and clk_set_rate() are equivalent
except the former does not modify the clock hardware in any way.

We can handle the sysc interconnect target module in a generic way for
many TI SoCs. Initially let's just enable domain clocks before the
children are probed.

McSPI IP provides per CS specific speed and mode selection. Therefore it
is possible to apply these settings only after CS is known. But
set_speed and set_mode can be called without bus being claimed, this
would lead driver to set up wrong CS (or previously used CS).
Fix this by apply set_speed and set_mode only if bus is already claimed.

struct ti_qspi_priv->max_hz is declared as unsigned int, so the following
error path check will always be false, even when "spi-max-frequency"
property is invalid/missing:
priv->max_hz = fdtdec_get_int(blob, node, "spi-max-frequency", -1);
if (priv->max_hz < 0) {
...
}
Replace the fdtdec call with dev_read_u32_default() and use 0 as the
default value. Error out if max_hz is zero.

The value of input pin for bank > 0 is always 0 for input subcommand.
The reason is that gpio_bank variable is computed only for invert and
output subcommands (it depends on number of arguments). The default
value of zero causes to shift the mask away for banks > 0.
Please note that info subcommand works as expected, because the input
pin values are accessed differently.

This has not been needed since parent information was added and we started
using indicies for references to other drivers instead of pointers. It was
kept around in the expectation that it might be needed later.
However with the latest updates, it doesn't seem likely that we'll need
this in the foreseeable future.
Drop dm_populate_phandle_data() from dtoc and driver model.

We use the U_BOOT_ prefix (i.e. U_BOOT_DRIVER) to declare a driver but
in every other case we just use DM_. Update the alias macros to use the
DM_ prefix.
We could perhaps rename U_BOOT_DRIVER() to DM_DRIVER(), but this macro
is widely used and there is at least some benefit to indicating it us a
U-Boot driver, particularly for code ported from Linux. So for now, let's
keep that name.

The current macro is a misnomer since it does not declare a device
directly. Instead, it declares driver_info record which U-Boot uses at
runtime to create a device.
The distinction seems somewhat minor most of the time, but is becomes
quite confusing when we actually want to declare a device, with
of-platdata. We are left trying to distinguish between a device which
isn't actually device, and a device that is (perhaps an 'instance'?)
It seems better to rename this macro to describe what it actually is. The
macros is not widely used, since boards should use devicetree to declare
devices.
Rename it to U_BOOT_DRVINFO(), which indicates clearly that this is
declaring a new driver_info record, not a device.

The #define of one struct to another has been around for a while. It
confuses dtoc and makes it think that struct spi_flash does not exist.
Make a few changes to improve things while we wait for migration to be
completed:
- Move the 'struct spi_flash' to column 1 so dtoc scans it
- Remove the #define when compiling dt-platdata.c
- Update the strange mtd_get/set_of_node() functions
- Use struct spi_nor in the drivers, so dtoc sees the correct struct
