It is then used by Marvell PHY driver, which gains support for probing LEDs connected to a PHY chip. When a netdev trigger is enabled on a Marvell PHY LED and configured in a compatible setting (the network device in the trigger settings must be the one attached to the PHY, and the link/tx/rx/interval settings must be supported by that particular LED), instead of blinking the LED in software, blinking is done by the PHY itself. Marek Marek Behún (7): leds: trigger: netdev: don't explicitly zero kzalloced data leds: trigger: netdev: simplify the driver by using bit field members leds: trigger: add API for HW offloading of triggers leds: trigger: netdev: support HW offloading net: phy: add simple incrementing phyindex member to phy_device struct net: phy: add support for LEDs connected to ethernet PHYs net: phy: marvell: support LEDs connected on Marvell PHYs Documentation/leds/leds-class.rst | 20 ++ drivers/leds/led-triggers.c | 1 + drivers/leds/trigger/ledtrig-netdev.c | 111 +++----- drivers/net/phy/marvell.c | 388 +++++++++++++++++++++++++- drivers/net/phy/phy_device.c | 143 ++++++++++ include/linux/leds.h | 27 ++ include/linux/ledtrig.h | 40 +++ include/linux/phy.h | 53 ++++ 8 files changed, 709 insertions(+), 74 deletions(-) create mode 100644 include/linux/ledtrig.h base-commit: cd29296fdfca919590e4004a7e4905544f4c4a32 -- 2.26.2
