Marek Behún e62ae2e27d refactor(drivers/marvell/comphy-3700): rename Clock Source Low value constants
The constants BUNDLE_PERIOD_SCALE and PLL_READY_DLY refer to two
multi-bit registers within the Clock Source Low register. These
constants are used as masks for those registers (and values are not
defined since we are writing zeros to them).

Give them the _MASK suffix.

Marek Behún e585c84ce5 refactor(drivers/marvell/comphy-3700): rename Clock Source Low register constants
The register at offset 0x1C3 is called Clock Source Low in functional
specification, but we use constant name GLOB_CLK_SRC_LO. Rename it to
RST_CLK_CTRL instead.

Marek Behún 86f6b55d47 refactor(drivers/marvell/comphy-3700): rename Idle Sync Enable register constants
According to the functional specification, the register at offset 0x48
is called Idle Sync Enable, not Unit Control or some such.

Rename the constants.

Only bit 12 of this register is defined, all other bits are reserved.
But for some reason the code needs the default value of the other bits,
so we also rename constant UNIT_CTRL_DEFAULT_VALUE to
IDLE_SYNC_EN_DEFAULT_VALUE.

Marek Behún 3f9a089297 refactor(drivers/marvell/comphy-3700): unify Generation Settings register values
Generation Settings registers have the same layout for different
generations and same setting (i.e. Generation 2 Settings 2 register has
the same layout as Generation 3 Settings 2).

So it does not make sense to prefix the constants for Settings 2 with
G3.

Instead change the prefixes to GSx_ for settings register x.

For Settings 2 of Gen 2 and Gen 3 we have some definitions in the first
and some in the second. Move them all to the first defined register (in
this case Gen 2, since the constant for Gen 1 is not defined because it
is not used).

Marek Behún b7b0575d12 refactor(drivers/marvell/comphy-3700): drop _ADDR suffixes
COMPHY register addresses are defined twice
- once for indirect access, where the constants are of the form
  COMPHY_<register_name>
- once for direct access, with constants of the form
  <register_name>_ADDR

But sometimes the first case also has this _ADDR suffix (and other times
not).

Drop it from those places to unify how we define these registers.

Marek Behún 580742d003 refactor(drivers/marvell/comphy-3700): move and add comment for COMPHY_RESERVED_REG
The COMPHY_RESERVED_REG (offset 0x0E) is currently defined between
COMPHY_KVCO_CAL_CTRL (0x02) and COMPHY_DIG_LOOPBACK_EN (0x23).

But this register does not come from PHY lane register space. The
address 0x0E is not relative to PHY lane registers base address.

It only exists in the indirect register space, before PHY lane 2
registers (which start at address 0x200).

Move its definition in the header and add a comment.

Marek Behún 6ba97f83db fix(drivers/marvell/comphy-3700): fix reference clock selection value names
The current definitions of reference clock speed register values
  #define PCIE_REF_CLOCK_SPEED_25M       REF_CLOCK_SPEED_30M
  #define USB3_REF_CLOCK_SPEED_25M       REF_CLOCK_SPEED_30M
is ambiguous. The name of the constant implies 25 MHz, but the value
implies 30 MHz, which may make the reader think that the setting has
something to do with both values.

In reality, the values have different tables for SerDes and PCIe/USB3
PHY mode. The value for 25 MHz for PCIe/USB3 mode (0x2) is the value
for 30 MHz for SerDes mode.

Instead of defining the PCIe/USB3 constants relative to SerDes
constants, define them with absolute values, thus making it a little bit
more obvious that different modes have different value tables.

Marek Behún bdcf44f1af fix(drivers/marvell/comphy-3700): fix SerDes frequency register value name
Constants SD_SPEED_1_25_G and SD_SPEED_2_5_G refer to SerDes frequency,
which is 1.25x that of data rate, since 1000base-x and 2500base-x use
the 8b/10b encoding:

  mode         frequency   data rate
  1000base-x   1.25  GHz    1   Gbps
  2500base-x   3.125 GHz    2.5 Gbps

But the first constant refers to the frequency, while the second to the
data rate, which does not make sense.

Since the values in the specification refer to frequency, change the
name of the constant SD_SPEED_2_5_G to SD_SPEED_3_125_G to also refer to
the frequency, as SD_SPEED_1_25_G does.

Antonio Nino Diaz c3cf06f1a3 Standardise header guards across codebase
All identifiers, regardless of use, that start with two underscores are
reserved. This means they can't be used in header guards.

The style that this project is now to use the full name of the file in
capital letters followed by 'H'. For example, for a file called
"uart_example.h", the header guard is UART_EXAMPLE_H.

The exceptions are files that are imported from other projects:

- CryptoCell driver
- dt-bindings folders
- zlib headers
