Other differences are: * It has separate data (DI), error (Line 1) and management (Line 2) irqs rather than one irq for all three. * Instead of using the High-speed peripheral bus clock for gPTP, it has a separate gPTP reference clock. v3: * Really renamed irq_en_dis_regs to irq_en_dis this time * Modified ravb_ptp_extts() to use irq_en_dis * Added Reviewed-by tags v2: * Just net patches in this series * Instead of reusing ch22 and ch24 interrupt names, use the proper names * Renamed irq_en_dis_regs to irq_en_dis * Squashed use of GIC reg versus GIE/GID and got rid of separate gptp_ptm_gic feature. * Move err_mgmt_irqs code under multi_irqs * Minor editing of the commit msgs Phil Edworthy (5): dt-bindings: net: renesas,etheravb: Document RZ/V2M SoC ravb: Separate handling of irq enable/disable regs into feature ravb: Support separate Line0 (Desc), Line1 (Err) and Line2 (Mgmt) irqs ravb: Use separate clock for gPTP ravb: Add support for RZ/V2M .../bindings/net/renesas,etheravb.yaml | 82 ++++++++++---- drivers/net/ethernet/renesas/ravb.h | 6 ++ drivers/net/ethernet/renesas/ravb_main.c | 102 ++++++++++++++++-- drivers/net/ethernet/renesas/ravb_ptp.c | 6 +- 4 files changed, 163 insertions(+), 33 deletions(-)
