      mvebu: cp110: introduce COMPHY porting layer · 42a29337
      Grzegorz Jaszczyk authored 
      

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

      drivers: imx: mxc_usdhc: Do not set MMC_RSP_48 for MMC_RESPONSE_R2 · a21da478
      Bryan O'Donoghue authored 
      commit 97d5db8c reverts an update to the
MMC layer that accompanied the original submission of this MMC driver this
is the right-thing-to-do in terms of the MMC spec.

Unfortunately the reversion also breaks this driver. The issue is the i.MX
controller doesn't want MMC_RSP_48 set for MMC_RESPONSE_R2.

The appropriate place to place that constraint is obviously in
drivers/imx/usdhc/imx_usdhc.c not in the shared MMC codebase. This patch
restores the logic the i.MX controller requires without breaking it for
everyone else.

Fixes: 97d5db8c
Fixes: 2a82a9c9

      plat/arm: Move norflash driver to drivers/ folder · aa7877c4
      Antonio Nino Diaz authored 
      

This way it can be reused by other platforms if needed.

Note that this driver is designed to work with the Versatile Express NOR
flash of Juno and FVP. In said platforms, the memory is organized as an
interleaved memory of two chips with a 16 bit word.

Any platform that wishes to reuse it with a different configuration will
need to modify the driver so that it is more generic.

      drivers: i2c: mentor: move platform code into header files · dfc0fb27
      Andre Przywara authored 
      

At the moment we have two I2C stub drivers (for the Allwinner and the
Marvell platform), which #include the actual .c driver file.
Change this into the more usual design, by renaming and moving the stub
drivers into platform specific header files and including these from the
actual driver file. The platform specific include directories make sure
the driver picks up the right header automatically.

      drivers: mentor: extract MI2CV driver from Marvell driver · 7e4d5620
      Icenowy Zheng authored 
      

The Marvell A8K SoCs use the MI2CV IP core from Mentor Graphics, which
is also used by Allwinner.

As Mentor Graphics allows a lot of customization, the MI2CV in the two
SoC families are not compatible, and driver modifications are needed.

Extract the common code to a MI2CV driver.

      marvell: drivers: use anonymous union in I2C driver · f348c351
      Icenowy Zheng authored 
      

The I2C controller found in Marvell A8K SoCs (and some older SoCs) mux
status and baudrate registers into the same address, however, it's a
vendor customization, and the original IP core by Mentor Graphics uses
two different addresses for the two registers.

Use anonymous union in the driver, in order to ease code sharing for
other SoC vendors that use this IP core (Allwinner SoCs that are newly
introduced to mainline ATF use this core).
