1cd7523f - net: lan969x: fix cyclic dependency reported by depmod

7280f01e - net: lan969x: add match data for lan969x

Wed, 23 Oct 2024 22:01:25 +0000

net: lan969x: add match data for lan969xAdd match data for lan969x, with initial fields for iomap, iomap_sizeand ioranges. Add new Kconfig symbol CONFIG_LAN969X_CONFIG for compilingthe lan969x driver.It has been decided to give lan969x its own Kconfig symbol, as aconsiderable amount of code is needed, beside the Sparx5 code, to addfull chip support (and more will be added in future series). Also thismakes it possible to compile Sparx5 without lan969x.Reviewed-by: Steen Hegelund Signed-off-by: Daniel Machon Link: https://patch.msgid.link/20241024-sparx5-lan969x-switch-driver-2-v2-6-a0b5fae88a0f@microchip.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/ethernet/microchip/Kconfig

5cd2340c - microchip: lan865x: add driver support for Microchip's LAN865X MAC-PHY

Mon, 09 Sep 2024 08:25:13 +0000

microchip: lan865x: add driver support for Microchip's LAN865X MAC-PHYThe LAN8650/1 is designed to conform to the OPEN Alliance 10BASE-T1xMAC-PHY Serial Interface specification, Version 1.1. The IEEE Clause 4MAC integration provides the low pin count standard SPI interface to anymicrocontroller therefore providing Ethernet functionality withoutrequiring MAC integration within the microcontroller. The LAN8650/1operates as an SPI client supporting SCLK clock rates up to a maximum of25 MHz. This SPI interface supports the transfer of both data (Ethernetframes) and control (register access).By default, the chunk data payload is 64 bytes in size. The EthernetMedia Access Controller (MAC) module implements a 10 Mbps half duplexEthernet MAC, compatible with the IEEE 802.3 standard. 10BASE-T1Sphysical layer transceiver integrated is into the LAN8650/1. The PHY andMAC are connected via an internal Media Independent Interface (MII).Reviewed-by: Andrew Lunn Signed-off-by: Parthiban Veerasooran Link: https://patch.msgid.link/20240909082514.262942-14-Parthiban.Veerasooran@microchip.comSigned-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/ethernet/microchip/Kconfig

e5f31552 - ethernet: fix PTP_1588_CLOCK dependencies

Thu, 12 Aug 2021 18:33:58 +0000

ethernet: fix PTP_1588_CLOCK dependenciesThe 'imply' keyword does not do what most people think it does, it onlypolitely asks Kconfig to turn on another symbol, but does not preventit from being disabled manually or built as a loadable module when theuser is built-in. In the ICE driver, the latter now causes a link failure:aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_eth_ioctl':ice_main.c:(.text+0x13b0): undefined reference to `ice_ptp_get_ts_config'ice_main.c:(.text+0x13b0): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_get_ts_config'aarch64-linux-ld: ice_main.c:(.text+0x13bc): undefined reference to `ice_ptp_set_ts_config'ice_main.c:(.text+0x13bc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_set_ts_config'aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_prepare_for_reset':ice_main.c:(.text+0x31fc): undefined reference to `ice_ptp_release'ice_main.c:(.text+0x31fc): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `ice_ptp_release'aarch64-linux-ld: drivers/net/ethernet/intel/ice/ice_main.o: in function `ice_rebuild':This is a recurring problem in many drivers, and we have discussedit several times befores, without reaching a consensus. I'm providinga link to the previous email thread for reference, which discussessome related problems.To solve the dependency issue better than the 'imply' keyword, introduce aseparate Kconfig symbol "CONFIG_PTP_1588_CLOCK_OPTIONAL" that any drivercan depend on if it is able to use PTP support when available, but worksfine without it. Whenever CONFIG_PTP_1588_CLOCK=m, those drivers arethen prevented from being built-in, the same way as with a 'depends onPTP_1588_CLOCK || !PTP_1588_CLOCK' dependency that does the same trick,but that can be rather confusing when you first see it.Since this should cover the dependencies correctly, the IS_REACHABLE()hack in the header is no longer needed now, and can be turned backinto a normal IS_ENABLED() check. Any driver that gets the dependencywrong will now cause a link time failure rather than being unable to usePTP support when that is in a loadable module.However, the two recently added ptp_get_vclocks_index() andptp_convert_timestamp() interfaces are only called from builtin code withethtool and socket timestamps, so keep the current behavior by stubbingthose out completely when PTP is in a loadable module. This should beaddressed properly in a follow-up.As Richard suggested, we may want to actually turn PTP support into a'bool' option later on, preventing it from being a loadable modulealtogether, which would be one way to solve the problem with the ethtoolinterface.Fixes: 06c16d89d2cb ("ice: register 1588 PTP clock device object for E810 devices")Link: https://lore.kernel.org/netdev/20210804121318.337276-1-arnd@kernel.org/Link: https://lore.kernel.org/netdev/CAK8P3a06enZOf=XyZ+zcAwBczv41UuCTz+=0FMf2gBz1_cOnZQ@mail.gmail.com/Link: https://lore.kernel.org/netdev/CAK8P3a3=eOxE-K25754+fB_-i_0BZzf9a9RfPTX3ppSwu9WZXw@mail.gmail.com/Link: https://lore.kernel.org/netdev/20210726084540.3282344-1-arnd@kernel.org/Acked-by: Shannon Nelson Acked-by: Jacob Keller Acked-by: Richard Cochran Reviewed-by: Vladimir Oltean Signed-off-by: Arnd Bergmann Link: https://lore.kernel.org/r/20210812183509.1362782-1-arnd@kernel.orgSigned-off-by: Jakub Kicinski List of files: /linux-6.15/drivers/net/ethernet/microchip/Kconfig
