Grzegorz Jaszczyk 38f6daca7a marvell: comphy: cp110: add support for SATA comphy polarity invert
The cp110 comphy has ability to invert RX and/or TX polarity. Polarity
depends on board design. Currently all supported boards doesn't require
SATA phy polarity invert, therefore COMPHY_POLARITY_NO_INVERT is set for
all boards.

Marcin Wojtas 8fa1340892 marvell: comphy: cp110: implement erratum IPCE_COMPHY-1353
According to erratum IPCE_COMPHY-1353 the TX_IDLE bit should
be toggled in addition to the XFI/SFI PHY reset.

Grzegorz Jaszczyk 8e8ec8cff7 marvell: comphy: update rx_training procedure
1) Relay only on rx training, remove parts responsible for tx training
(trx training).
2) Add extra steps e.g. preconfigure FFE before starting training.
3) Remove some unnecessary steps like RRBS31 loopback setting which
shouldn't be relevant for tx_training.

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

Grzegorz Jaszczyk 42a293379e mvebu: cp110: introduce COMPHY porting layer
Some of COMPHY parameters depends on the hw connection between the SoC
and the PHY, which can vary on different boards e.g. due to different
wires length. Define the "porting layer" with some defaults
parameters. It ease updating static values which needs to be updated due
to board differences, which are now grouped in one place.

Example porting layer for a8k-db is under:
plat/marvell/a8k/a80x0/board/phy-porting-layer.h

If for some boards parameters are not defined (missing
phy-porting-layer.h), the default values are used
(drivers/marvell/comphy/phy-default-porting-layer.h)
and the following compilation warning is show:
"Using default comphy params - you may need to suit them to your board".

The common COMPHY driver code is extracted in order to be shared with
future COMPHY driver for A3700 SoC platforms

Grzegorz Jaszczyk 3c0024cc2c mvebu: cp110: fix spelling in register definition
Use PF instead of PP post-fix, since it is referring to "Phase Final"
(only G3 related register had correct spelling for relevant bit).
