net, qe: add DM support for QE UEC ethernet
add DM/DTS support for the UEC ethernet on QUICC Engine
Block.
Signed-off-by: Heiko Schocher <hs@denx.de>
Patch-cc: Mario Six <mario.six@gdsys.cc>
Patch-cc: Qiang Zhao <qiang.zhao@nxp.com>
Patch-cc: Holger Brunck <holger.brunck@hitachi-powergrids.com>
Patch-cc: Madalin Bucur <madalin.bucur@oss.nxp.com>
Series-changes: 3
- revert:
commit "3374264df97b" ("drivers: net: qe: deselect QE when DM_ETH is enabled")
as now qe works with DM and DM_ETH support.
- fix mailaddress from Holger
Series-changes: 2
- add comments from Qiang Zhao:
- add device node documentation
- I did not drop the dm_qe_uec_phy.c and use drivers/net/fsl_mdio.c
because using drivers/net/fsl_mdio.c leads in none existent
udevice mdio@3320
instead boards with DM ETH support should use now this
driver.
- remove RFC tag
Commit-notes:
- I let the old none DM based implementation in code
so boards should work with old implementation.
This Code should be removed if all boards are converted
to DM/DTS.
- add the DM based qe uec driver under drivers/net/qe
- Therefore copied the files uccf.c uccf.h uec.h from
drivers/qe. So there are a lot of Codingstyle problems
currently. I fix them in next version if this RFC
patch is OK or it needs some changes.
- The dm based driver code is now under drivers/net/qe/dm_qe_uec.c
Used a lot of functions from drivers/qe/uec.c
- seperated the PHY specific code into seperate file
drivers/net/qe/dm_qe_uec_phy.c

* UCC (Unified Communications Controllers)
|
||||
|
||||
Required properties:
|
||||
- compatible : ucc_geth
|
||||
- cell-index : the ucc number(1-8), corresponding to UCCx in UM.
|
||||
- reg : Offset and length of the register set for the device
|
||||
- rx-clock-name: the UCC receive clock source
|
||||
"none": clock source is disabled
|
||||
"brg1" through "brg16": clock source is BRG1-BRG16, respectively
|
||||
"clk1" through "clk24": clock source is CLK1-CLK24, respectively
|
||||
- tx-clock-name: the UCC transmit clock source
|
||||
"none": clock source is disabled
|
||||
"brg1" through "brg16": clock source is BRG1-BRG16, respectively
|
||||
"clk1" through "clk24": clock source is CLK1-CLK24, respectively
|
||||
The following two properties are deprecated. rx-clock has been replaced
|
||||
with rx-clock-name, and tx-clock has been replaced with tx-clock-name.
|
||||
Drivers that currently use the deprecated properties should continue to
|
||||
do so, in order to support older device trees, but they should be updated
|
||||
to check for the new properties first.
|
||||
- rx-clock : represents the UCC receive clock source.
|
||||
0x00 : clock source is disabled;
|
||||
0x1~0x10 : clock source is BRG1~BRG16 respectively;
|
||||
0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively.
|
||||
- tx-clock: represents the UCC transmit clock source;
|
||||
0x00 : clock source is disabled;
|
||||
0x1~0x10 : clock source is BRG1~BRG16 respectively;
|
||||
0x11~0x28: clock source is QE_CLK1~QE_CLK24 respectively.
|
||||
- phy-handle : The phandle for the PHY connected to this controller.
|
||||
- phy-connection-type : a string naming the controller/PHY interface type,
|
||||
i.e., "mii" (default), "rmii", "gmii", "rgmii", "rgmii-id" (Internal
|
||||
Delay), "rgmii-txid" (delay on TX only), "rgmii-rxid" (delay on RX only),
|
||||
"tbi", or "rtbi".
|
||||
- pio-handle : The phandle for the Parallel I/O port configuration.
|
||||
|
||||
Deprecated properties:
|
||||
- device-id : the ucc number(1-8), corresponding to UCCx in UM.
|
||||
you should use cell-index
|
||||
|
||||
Example:
|
||||
ucc@2000 {
|
||||
device_type = "network";
|
||||
compatible = "ucc_geth";
|
||||
cell-index = <1>;
|
||||
reg = <2000 200>;
|
||||
interrupts = <a0 0>;
|
||||
interrupt-parent = <700>;
|
||||
mac-address = [ 00 04 9f 00 23 23 ];
|
||||
rx-clock = "none";
|
||||
tx-clock = "clk9";
|
||||
phy-handle = <212000>;
|
||||
phy-connection-type = "gmii";
|
||||
pio-handle = <140001>;
|
||||
