stmmac: MDC clock dynamically based on the csr clock input · cd7201f4

Giuseppe CAVALLARO authored Apr 04, 2012

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.

stmmac: extend CSR Clock Range programming · 18f05d64

Giuseppe CAVALLARO authored Apr 04, 2012

The CSR Clock Range has been reworked and new macros has
been added in the platform header to allow the CSR Clock
Range selection in the GMII Address Register.
The previous work didn't add the other fields
that can be used to achieve MDC clock of frequency
higher than the IEEE 802.3 specified frequency limit
of 2.5 MHz and program a clock divider of lower value.
On such platforms, these are used indeed so this patch
adds them.

stmmac: Replace infinite loops by timeouts in mdio r/w · 39b401db

This patch removes the infinite waits from the mdio read and

the timeout handling. In case if a time out occurs, an error is

stmmac: re-work the internal GMAC DMA platf parameters · 8327eb65

Deepak SIKRI authored Apr 04, 2012

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.

stmmac: Define MDC clock selection macros · faeae3fa

Deepak SIKRI authored Apr 04, 2012

The patch adds the macros to be used for MDC clock selection. The MDC clock
frequency is based on scaled system clock, and has to be confined to a range
of 1-2.5 MHz. Based on the input CSR clock, the scaling factor has to be
selected.
The platform specific code will provide the default value of this scaling
factor, based on the input CSR clock.
There is an option to set MDC clock higher than the IEEE 802.3 specified
frequency limit of 2.5 MHz. This applies for the interfacing chips that
support higher MDC clocks. The resultant higher clock of 12.5 MHz requires
additional Macros to be defined for the clock divider corresponding to the
to the following selection.
-----------------------------------------
	Selection	MDC Clock
-----------------------------------------
	1000 		clk_csr_i/4
	1001 		clk_csr_i/6
	1010 		clk_csr_i/8
	1011 		clk_csr_i/10
	1100 		clk_csr_i/12
	1101	 	clk_csr_i/14
	1110 		clk_csr_i/16
	1111 		clk_csr_i/18

This support has to be added both in the include file, as well as driver. The
driver need to program the registers based on the interfacing chips. This would
be more board specific information and needs to be passed through the platform
code to the driver. This work would be carried out in the future patch set
release.

stmmac: sanitize the rx coe and add the type-1 csum (v2) · 38912bdb

Deepak SIKRI authored Apr 04, 2012

This patch sanities the RX coe and adds the Type-1 Rx checksum offload engine (COE).

So the RX COE can be passed through the platform but can be fixed
at run-time in case of the core has the HW capability register.

Also to support the Type-1 Rx COE the driver must append the
HW checksum at the end of payload in case the Rx checksum
engine was used to  offload the HW checksum.

This v2 version also fixes the IPC that has to be enabled and verified.

stmmac: Define CSUM offload engine Types · 55f9a4d6

Deepak SIKRI authored Apr 04, 2012

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.

stmmac: Allow stmmac to work with other PHY buses(v3). · f142af2e

Srinivas Kandagatla authored Apr 04, 2012

As stmmac mdio bus name prefix is hardcoded in the driver, this allows
only phys on stmmac mdio buses to connect, however stmmac should allow
phys on other mdio buses too.

This patch adds new variable phy_bus_name to plat_stmmacenet_data
struct to let the BSP decide which phy bus to be used by stmmac driver.
A typical use-case is to have generic MDIO buses like mdio-gpio on top
of stmmac.
