Sonic Zhang e2a240c7d3 driver:net:stmmac: Disable DMA store and forward mode if platform data force_thresh_dma_mode is set.
Some synopsys ip implementation doesn't support DMA store and forward mode,
such as BF60x. So, set force_thresh_dma_mode to use DMA thresholds only.
Update document and devicetree as well.

Giuseppe CAVALLARO 49cfbf675c stmmac: review driver documentation
This patch reviews the driver documentation file;
for example, there were some new fields (in the driver
module parameter section) and the ptp files were
not documented.

Srinivas Kandagatla d56631a66c net:stmmac: Remove bus_id from mdio platform data.
This patch removes bus_id from mdio platform data, The reason to remove
bus_id is, stmmac mdio bus_id is always same as stmmac bus-id, so there
is no point in passing this in different variable.
Also stmmac ethernet driver connects to phy with bus_id passed its
platform data.
So, having single bus-id is much simpler.

Giuseppe CAVALLARO cd7201f477 stmmac: MDC clock dynamically based on the csr clock input
If a specific clk_csr value is passed from the platform
this means that the CSR Clock Range selection cannot be
changed at run-time and it is fixed (as reported in the driver
documentation). Viceversa the driver will try to set the MDC
clock dynamically according to the actual clock input.

Deepak SIKRI 8327eb65e7 stmmac: re-work the internal GMAC DMA platf parameters
This patch re-works the internal GMAC DMA parameters
passed from the platform.
In the past, we only passed the pbl but, with new core,
other parameters can be passed and are mandatory on some
platforms.

New parameters are documented in stmmac.txt because this
patch has an impact for many platforms.

Deepak SIKRI 55f9a4d6fa stmmac: Define CSUM offload engine Types
This patch explicitly defines the CSUM offload engine type which need
(not mandatory) to be passed from the platform code.
STMMAC core supports two check sum offload engine types- Type-1 & Type-2.
Also, there are STMMAC cores that do not have the check sum offload
capabilities.

The behaviour of Type-1 & Type-2 cores related to provision of checksum
increases the packet length for Type-1 cores by 2, as the checksum is appended
at the end of data packet and the same is made accountable in the DMA status.
The STMMAC cores beyond Version-3.5 provide HW interface registers which allows
the user to read the HW capabilities, while to support the previous cores the
information related to HW capabilities has to be provided from the platform
code.

The Type-1 cores which do not have the HW register interface need this
information.

This patch also updates the driver's doc.
