From: Pieter Van Trappen <pieter.van.trappen@xxxxxxx> Add WoL support for KSZ8795 family of switches. This code was tested with a KSZ8794 chip. Strongly based on existing KSZ9477 code which has now been moved to ksz_common instead of duplicating, as proposed during the review of the v1 version of this patch. In addition to the device-tree addition and the actual code, there's an additional patch to check the erratum workaround application using the now available indirect register read. Signed-off-by: Pieter Van Trappen <pieter.van.trappen@xxxxxxx> --- v2: - generalize instead of duplicate, much improved - variable declaration reverse Christmas tree - ksz8_handle_global_errata: return -EIO in case of indirect write failure - ksz8_ind_read8/write8: document functions - ksz8_handle_wake_reason: no need for additional write to clear - fix wakeup_source origin comments v1: https://lore.kernel.org/netdev/20240717193725.469192-1-vtpieter@xxxxxxxxx/ Pieter Van Trappen (5): dt-bindings: net: dsa: microchip: add microchip,pme-active-high flag net: dsa: microchip: move KSZ9477 WoL functions to ksz_common net: dsa: microchip: generalize KSZ9477 WoL functions at ksz_common net: dsa: microchip: add WoL support for KSZ87xx family net: dsa: microchip: check erratum workaround through indirect register read .../bindings/net/dsa/microchip,ksz.yaml | 5 + drivers/net/dsa/microchip/ksz8.h | 3 + drivers/net/dsa/microchip/ksz8795.c | 99 +++++++- drivers/net/dsa/microchip/ksz8795_reg.h | 4 +- drivers/net/dsa/microchip/ksz9477.c | 195 +--------------- drivers/net/dsa/microchip/ksz9477.h | 5 - drivers/net/dsa/microchip/ksz9477_reg.h | 12 - drivers/net/dsa/microchip/ksz_common.c | 219 +++++++++++++++++- drivers/net/dsa/microchip/ksz_common.h | 31 ++- 9 files changed, 350 insertions(+), 223 deletions(-) base-commit: 0a658d088cc63745528cf0ec8a2c2df0f37742d9 -- 2.43.0
