Subject: [PATCH net-next v4 00/12] Add support for OPEN Alliance 10BASE-T1x MACPHY Serial Interface
Date: Thu, 18 Apr 2024 18:26:36 +0530 [thread overview]
Message-ID: <20240418125648.372526-1-Parthiban.Veerasooran@microchip.com> (raw)
This patch series contain the below updates,
- Adds support for OPEN Alliance 10BASE-T1x MACPHY Serial Interface in the
net/ethernet/oa_tc6.c.
Link to the spec:
-----------------
https://opensig.org/download/document/OPEN_Alliance_10BASET1x_MAC-PHY_Serial_Interface_V1.1.pdf
- Adds driver support for Microchip LAN8650/1 Rev.B1 10BASE-T1S MACPHY
Ethernet driver in the net/ethernet/microchip/lan865x/lan865x.c.
Link to the product:
--------------------
https://www.microchip.com/en-us/product/lan8650
Testing Details:
----------------
The driver performance was tested using iperf3 in the below two setups
separately.
Setup 1:
--------
Node 0 - Raspberry Pi 4 with LAN8650 MAC-PHY
Node 1 - Raspberry Pi 4 with EVB-LAN8670-USB USB Stick
Setup 2:
--------
Node 0 - SAMA7G54-EK with LAN8650 MAC-PHY
Node 1 - Raspberry Pi 4 with EVB-LAN8670-USB USB Stick
Achieved maximum of 9.4 Mbps.
Some systems like Raspberry Pi 4 need performance mode enabled to get the
proper clock speed for SPI. Refer below link for more details.
https://github.com/raspberrypi/linux/issues/3381#issuecomment-1144723750
Changes:
v2:
- Removed RFC tag.
- OA TC6 framework configured in the Kconfig and Makefile to compile as a
module.
- Kerneldoc headers added for all the API methods exposed to MAC driver.
- Odd parity calculation logic updated from the below link,
https://elixir.bootlin.com/linux/latest/source/lib/bch.c#L348
- Control buffer memory allocation moved to the initial function.
- struct oa_tc6 implemented as an obaque structure.
- Removed kthread for handling mac-phy interrupt instead threaded irq is
used.
- Removed interrupt implementation for soft reset handling instead of
that polling has been implemented.
- Registers name in the defines changed according to the specification
document.
- Registers defines are arranged in the order of offset and followed by
register fields.
- oa_tc6_write_register() implemented for writing a single register and
oa_tc6_write_registers() implemented for writing multiple registers.
- oa_tc6_read_register() implemented for reading a single register and
oa_tc6_read_registers() implemented for reading multiple registers.
- Removed DRV_VERSION macro as git hash provided by ethtool.
- Moved MDIO bus registration and PHY initialization to the OA TC6 lib.
- Replaced lan865x_set/get_link_ksettings() functions with
phy_ethtool_ksettings_set/get() functions.
- MAC-PHY's standard capability register values checked against the
user configured values.
- Removed unnecessary parameters validity check in various places.
- Removed MAC address configuration in the lan865x_net_open() function as
it is done in the lan865x_probe() function already.
- Moved standard registers and proprietary vendor registers to the
respective files.
- Added proper subject prefixes for the DT bindings.
- Moved OA specific properties to a separate DT bindings and corrected the
types & mistakes in the DT bindings.
- Inherited OA specific DT bindings to the LAN865x specific DT bindings.
- Removed sparse warnings in all the places.
- Used net_err_ratelimited() for printing the error messages.
- oa_tc6_process_rx_chunks() function and the content of oa_tc6_handler()
function are split into small functions.
- Used proper macros provided by network layer for calculating the
MAX_ETH_LEN.
- Return value of netif_rx() function handled properly.
- Removed unnecessary NULL initialization of skb in the
oa_tc6_rx_eth_ready() function removed.
- Local variables declaration ordered in reverse xmas tree notation.
v3:
- Completely redesigned all the patches.
- Control and data interface patches are divided into multiple small
patches.
- Device driver APIs added in the oa-tc6-framework.rst file.
- Code readability improved in all the patches.
- Defined macros wherever is possible.
- Changed RESETC to STATUS0_RESETC for improving the readability.
- Removed OA specific DT bindings.
- Used default configurations defined in the OA spec.
- All variables are named properly as per OA spec for more redability.
- Bigger functions are split into multiple smaller functions.
- DT binding check is done.
- Phy mask is removed in phy scanning.
- Used NET_RX_DROP to compare the rx packet submission status.
- Indentation in the Kconfig file corrected.
- Removed CONFIG_OF and CONFIG_ACPI ifdefs.
- Removed MODULE_ALIAS().
v4:
- Fixed indentation in oa-tc6-framework.rst file.
- Replaced ENODEV error code with EPROTO in the
oa_tc6_check_ctrl_write_reply and oa_tc6_check_ctrl_read_reply()
functions.
- Renamed oa_tc6_read_sw_reset_status() function as
oa_tc6_read_status0().
- Changed software reset polling delay as 1ms and polling timeout as 1s.
- Implemented clause 45 registers direct access.
- Replaced ENODEV error code with ENOMEM in the
oa_tc6_mdiobus_register() function.
- Changed transmit skbs queue size as 2.
- Added skb_linearize() function to convert contiguous packet data.
- Checked kthread_should_stop() in the oa_tc6_spi_thread_handler()
function before proceeding for the oa_tc6_try_spi_transfer().
- Removed netdev_err() print in the oa_tc6_allocate_rx_skb() function.
- Added spi-peripheral-props reference in the dt-bindings.
- Changed the fallback order in the dt-bindings.
- Replaced netif_start_queue() with netif_wake_queue().
- Empty data transfer performed in the oa_tc6_init() function to clear
the reset complete interrupt.
- ZARFE bit in the CONFIG0 register is set to 1 to avoid lan865x halt
based on the recommendation in the lan865x errata.
