2025-01-11net: phy: dp83822: Add support for PHY LEDs on DP83822Dimitri Fedrau
The DP83822 supports up to three configurable Light Emitting Diode (LED) pins: LED_0, LED_1 (GPIO1), COL (GPIO2) and RX_D3 (GPIO3). Several functions can be multiplexed onto the LEDs for different modes of operation. LED_0 and COL (GPIO2) use the MLED function. MLED can be routed to only one of these two pins at a time. Add minimal LED controller driver supporting the most common uses with the 'netdev' trigger.

The next 3 patches are by Sean Nyekjaer and target the tcan4x5x driver. First the DT bindings is converted to DT schema, then nWKRQ voltage selection is added to the driver. Dario Binacchi's patch for the sun4i_can makes the driver more consistent by adding a likely() to the driver. Another patch by Sean Nyekjaer for the tcan4x5x driver gets rid of a false error message. Charan Pedumuru converts the atmel-can DT bindings to DT schema. The next 2 patches are by Oliver Hartkopp. The first one maps Oliver's former mail addresses to a dedicated CAN mail address. The second one assigns net/sched/em_canid.c additionally to the CAN maintainers. Ariel Otilibili's patch removes dead code from the CAN dev helper. The next 3 patches are by Sean Nyekjaer and add HW standby support to the tcan4x5x driver. A patch by Dario Binacchi fixes the DT bindings for the st,stm32-bxcan driver. The last 4 patches are by Jimmy Assarsson and target the kvaser_usb and the kvaser_pciefd driver: error statistics are improved and CAN_CTRLMODE_BERR_REPORTING is added. * tag 'linux-can-next-for-6.14-20250110' of git://git.kernel.org/pub/scm/linux/kernel/git/mkl/linux-can-next: can: kvaser_pciefd: Add support for CAN_CTRLMODE_BERR_REPORTING can: kvaser_pciefd: Update stats and state even if alloc_can_err_skb() fails can: kvaser_usb: Add support for CAN_CTRLMODE_BERR_REPORTING can: kvaser_usb: Update stats and state even if alloc_can_err_skb() fails dt-bindings: can: st,stm32-bxcan: fix st,gcan property type can: m_can: call deinit/init callback when going into suspend/resume can: tcan4x5x: add deinit callback to set standby mode can: m_can: add deinit callback can: dev: can_get_state_str(): Remove dead code MAINTAINERS: assign em_canid.c additionally to CAN maintainers mailmap: add an entry for Oliver Hartkopp dt-bindings: net: can: atmel: Convert to json schema can: tcan4x5x: get rid of false clock errors can: sun4i_can: continue to use likely() to check skb can: tcan4x5x: add option for selecting nWKRQ voltage dt-bindings: can: tcan4x5x: Document the ti,nwkrq-voltage-vio option dt-bindings: can: convert tcan4x5x.txt to DT schema dt-bindings: can: mpfs: add PIC64GX CAN compatibility ==================== Link: https://patch.msgid.link/20250110112712.3214173-1-mkl@pengutronix.de Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2025-01-10Merge branch 'net-stmmac-clean-up-and-fix-eee-implementation'Jakub Kicinski
Russell King says: ==================== net: stmmac: clean up and fix EEE implementation This is a rework of stmmac's EEE support in light of the addition of EEE management to phylib. It's slightly more than 15 patches, but I think it makes sense to be so. Patch 1 adds configuration of the receive clock phy_eee_rx_clock_stop() (which was part of another series, but is necessary for this patch set.) Patch 2 converts stmmac to use phylib's tracking of tx_lpi_timer. Patch 3 corrects the data type used for things involving the LPI timer. The user API uses u32, so stmmac should do too, rather than blindly converting it to "int". eee_timer is left for patch 4. Patch 4 (new) uses an unsigned int for eee_timer. Patch 5 makes stmmac EEE state depend on phylib's enable_tx_lpi flag, thus using phylib's resolution of EEE state. Patch 6 removes redundant code from the ethtool EEE operations. Patch 7 removes some redundant code in stmmac_disable_eee_mode() and renames it to stmmac_disable_sw_eee_mode() to better reflect its purpose. Patch 8 removes the driver private tx_lpi_enabled, which is managed by phylib since patch 4. Patch 9 removes the dependence of EEE error statistics on the EEE enable state, instead depending on whether EEE is supported by the hardware. Patch 10 removes phy_init_eee(), instead using phy_eee_rx_clock_stop() to configure whether the PHY may stop the receive clock. Patch 11 removes priv->eee_tw_timer, which is only ever set to one value at probe time, effectively it is a constant. Hence this is unnecessary complexity. Patch 12 moves priv->eee_enabled into stmmac_eee_init(), and placing it under the protection of priv->lock, except when EEE is not supported (where it becomes constant-false.) Patch 13 moves priv->eee_active also into stmmac_eee_init(), so the indication whether EEE should be enabled or not is passed in to this function. Since both priv->eee_enabled and priv->eee_active are assigned true/false values, they should be typed "bool". Make it sew in patch 14. No Singer machine required. Patch 15 moves the initialisation of priv->eee_ctrl_timer to the probe function - it makes no sense to re-initialise the timer each time we want to start using it. Patch 16 removes the unnecessary EEE handling in the driver tear-down method. The core net code will have brought the interface down already, meaning EEE has already been disabled. Patch 17 reorganises the code to split the hardware LPI timer control paths from the software LPI timer paths. Patch 18 works on this further by eliminating stmmac_lpi_entry_timer_config() and making direct calls to the new functions. This reveals a potential bug where priv->eee_sw_timer_en is set true when EEE is disabled. This is not addressed in this series, but will be in a future separate patch - so that if fixing that causes a regression, it can be handled separately. ==================== Link: https://patch.msgid.link/Z36sHIlnExQBuFJE@shell.armlinux.org.uk Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2025-01-10net: stmmac: remove unnecessary EEE handling in stmmac_release()Russell King (Oracle)

As mac_link_down() will call stmmac_eee_init(false), this will set both priv->eee_active and priv->eee_enabled to be false, deleting the eee_ctrl_timer if priv->eee_enabled was previously set. As stmmac_release() calls phylink_stop() before checking whether priv->eee_enabled is true, this is a condition that can never be satisfied, and thus the code within this if() block will never be executed.

When stmmac_ethtool_op_get_eee() is called, stmmac sets the tx_lpi_timer and tx_lpi_enabled members, and then calls into phylink and thus phylib. phylib overwrites these members. phylib will also cause a link down/link up transition when settings that impact the MAC have been changed. Convert stmmac to use the tx_lpi_timer setting in struct phy_device, updating priv->tx_lpi_timer each time when the link comes up, rather than trying to maintain this user setting itself. We initialise the phylib tx_lpi_timer setting by doing a get_ee-modify-set_eee sequence with the last known priv->tx_lpi_timer value.

suspend" Sean Nyekjaer <sean@geanix.com> says: When downing the tcan4x5x there is no reason to keep the tcan4x5x in "normal" mode and waste power. So set standby mode when the interface is down and normal mode when interface is up. Also when going into suspend, set the tcan4x5x into standby mode. The tcan4x5x can still be used as a wake-source when in standby as low power RX is enabled.

2025-01-09netconsole: selftest: verify userdata entry limitBreno Leitao
Add a new selftest for netconsole that tests the userdata entry limit functionality. The test performs two key verifications: 1. Create MAX_USERDATA_ITEMS (16) userdata entries successfully 2. Confirm that attempting to create an additional userdata entry fails The selftest script uses the netcons library and checks the behavior by attempting to create entries beyond the maximum allowed limit.

2025-01-09netconsole: selftest: Delete all userdata keysBreno Leitao
Modify the cleanup function to remove all userdata keys created during the test, instead of just deleting a single predefined key. This ensures a more thorough cleanup of temporary resources. Move the KEY_PATH variable definition inside the set_user_data function to reduce global variables and improve encapsulation. The KEY_PATH variable is now dynamically created when setting user data. This change has no effect on the current test, while improving an upcoming test that would create several userdata entries.

2025-01-09netconsole: selftest: Split the helpers from the selftestBreno Leitao
Split helper functions from the netconsole basic test into a separate library file to enable reuse across different netconsole tests. This change only moves the existing helper functions to lib/sh/lib_netcons.sh while preserving the same test functionality. The helpers provide common functions for: - Setting up network namespaces and interfaces - Managing netconsole dynamic targets - Setting user data - Handling test dependencies - Cleanup operations Do not make any change in the code, other than the mechanical separation.
