DP83TC811S-Q1: The driver code matches the kernel version

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/net/phy/dp83tc811.c

kernel version:3.18.120

}

when i add  code to support  C45 as fllow:

ethphy0: ethernet-phy@1 {

compatible = "ethernet-phy-ieee802.3-c45";

reg = <0>;

};

It cannot  read phyID,phy_id is 0

3.446179] libphy: emac-mdio: probed
[ 3.452680] get_phy_device:===>r(0)phy_id(0) is_c45=1

I think it is a problem with the phy_read_mmd function, which is inconsistent with the current kernel version.

Can you provide a driver based on the current kernel version

    Hello,

    We are looking into this issue and will follow up early next week.

    Thank you,

    Hello,

    There is a backport for the older  Kernel version 3.10 here: 

    https://git.ti.com/gitweb?p=ti-analog-linux-kernel/dmurphy-analog.git;a=shortlog;h=refs/heads/dp83811_310_version

    You will need to take the patches from the 3.10.17 tag on that branch. There is a patch to fix the C45 clause. 

    Thank you,

    Nikhil

    dear  Nikhil

    in py platform :kernel 3.18.120

    The current version phy_read_mmd interface will judge is_c45, does our current IC support this protocol?
    We follow the code that does not support C45 implementation, resulting in a direct return at the entrance of the phy_read_mmd function

    The phy_read_mmd interface is currently available, but it is not applicable to the current dp83811driver,

    I check the branch code you provided, dp83822.c, which only adapts to the phy id of dp83811, but the register definition is different from that of dp83822 and cannot be incorporated

    Please provide a phy_read_mmd and phy_write_mmd interface suitable for the current kernel version

    dear  Nikhil

    Or how to implement the read and write operations of dp83811 based on the current kernel version interface

    Give the latest dp83811 driver,
    We tried to modify as follows, but found that the write function to write and it  was not successful

    change phy_write_mmd to phy_write_mmd_indirect

    and change phy_read_mmd to phy_read_mmd_indirect.

    thanks

    dear  nikhil:

    After we modify and after the device up, no error is reported, but the device cannot be pinged.

    please help to check.

    Hello,

    To summarize, the new Kernel is now working, you are able to read/write registers, device powers up, but cannot ping. Is this correct?

    Does the device link up?

    Can you provide a register read for registers 0, 1, and extended register 467?

    Thank you,

    Nikhil

    dear  nikhil:

    yes，the DP83TC811 driver(new kernel) of read/write interfaces  had working  in  the 3.18.120 Kernel after we modify : 

    change phy_write_mmd to phy_write_mmd_indirect

    and change phy_read_mmd to phy_read_mmd_indirect.

    My test steps:
    ifconfig eth0 hw ether 00:11:22:33:44:55
    cat /sys/module/dp83tc811/parameters/reg_val //Print register
    ifconfig eth0 up
    cat /sys/module/dp83tc811/parameters/reg_val //Print register
    brctl addif br0 eth0
     in the log uploaded yesterday, there is no error, but the device cannot be pinged through ping the PC.

    so  i don't know  read/write interfaces （after changed） is  correct.

    Does the device link up?

    i think thedevice is link up.

    dear  nikhil:

    The following is the process of reading register 0x467. I check that it is consistent with datasheet

    1、write 0x1f   to  reg0xd

    2、write  0x467  to reg0x0e

    3、write  0x401f  to  reg0xd

    4、read 0x0e reg to get  result

    reg=0x467  value is  0x000

    Hello,

    Based on the register values, it looks like there is no link, and the device is set for 100M speed in SGMII mode. Is this the desired mode of operation?

    Could you also provide me a schematic?

    Thank you,

    Nikhil

    dear  Nikhil 

    sorry for late repaly because we have a holiday.

     our device is sure working  in 100M speed and in SGMII mode,this is correct and the desired mode of operation.

    Why the device has no link, which register configuration problem or process problem?

    We need to provide a schematic diagram about  what?

    I don‘t  understand.

    thanks

    dear  Nikhil：

    any update ?

    this is QUALCOMM FAE replay：

    We are not getting what is the issue you are facing in EMAC driver.
    It seems it is stuck at PHY layer while writing to PHY registers,

    dear Nikhil

    We found that the general register 0x00~0xf register has no problem in reading and writing, only the extension register has a problem in writing

    Please help analyze it as soon as possible, this problem has seriously affected the progress of the project.

    thanks

    Hello,

    Thank you for your patience. Section 8.4.20 highlights the 4 step process of reading an extended register. I see duplicate lines of code, what is the distinction between the lines [650.887902] and [650.894788] ? I also see that register 0xD is being set to 0x0, is this what line [ 650.881906] is doing?

    I have copied from the datasheet the steps to read/write the extended register set. Can you clarify the above questions and confirm the steps below are being followed?

    To read a register in the extended register set:

    1. Write the value 0x1F (address function field = 00, DEVAD = '11111') to register REGCR.

    2. Write the desired register address to register ADDAR.

    3. Write the value 0x401F (data, no post increment function field = 01, DEVAD = '11111') to register REGCR.

    4. Read the content of the desired extended register set in register ADDAR.

     

    To write a register in the extended register set:

    1. Write the value 0x1F (address function field = 00, DEVAD = '11111') to register REGCR.

    2. Write the desired register address to register ADDAR.

    3. Write the value 0x401F (data, no post increment function field = 01, DEVAD = '11111') to register REGCR.

    4. Write the content of the desired extended register set to register ADDAR.

    These steps must be done every time an individual register must be accessed. 

    Thank you,

    Nikhil

    Hello,

    The schematic looks ok. Could you clarify  the distinction between the lines [ 651.003933] and [ 651.010732] in the above reply? It looks like the same write function is duplicated? Line [ 650.978134] suggests that register 0xD is being written to 0x0? It looks like register 0xE is also being written to 0x0.

    If this is the case please remove the duplicate statements and do not set registers 0xD and 0xE to 0x0 between read and write statements. Please follow the 4-step process described in the datasheet. 

    Please let me know if this does not solve the issue.

    Thank you,

    Nikhil

    dear  Nikhil

    between the lines [ 651.003933] and [ 651.010732] is  the same function print,U need to  ignore the line [ 651.010732] print.

    Line [ 650.978134],WR 0x0d -> 0x0000       this is not write 0x0000 to 0xd ,this is write operation return print, U need to  ignore it。

    Hello,

    It looks like Bit[11] of register 0x04A0 is a self-clearing bit. This means, that though you may write to it, it will self clear back to 0, which is why you see the subsequent read is back to 0x1000. To test the functionality of the WoL in this manner, you may enable WoL, set the output to level mode (this will create an interrupt that is constantly pulled high rather than a single pulse), then create a WoL event. Observe that the signal is high, write 0x04A0 = 0x1800 and observe the signal clear and the bit clear. Please let me know if this solves the issue.

    Thank you,

    Nikhil

    Hello,

    There are different types of loopback tests, which one is the desired loopback test? What function are you trying to test?

    Has the extended register access issue been resolved?

    Thank you,

    Nikhil
