The DMAC and EMAC blocks of Gigabit Ethernet IP is almost similar to Ethernet AVB. The Gigabit Etherner IP consists of Ethernet controller (E-MAC), Internal TCP/IP Offload Engine (TOE) and Dedicated Direct memory access controller (DMAC). With few changes in driver, we can support Gigabit ethernet driver as well. This patch series is aims to support the same RFC->V1 * Incorporated feedback from Andrew, Sergei, Geert and Prabhakar * https://patchwork.kernel.org/project/linux-renesas-soc/list/?series=515525 Biju Das (18): dt-bindings: net: renesas,etheravb: Document Gigabit Ethernet IP drivers: clk: renesas: rzg2l-cpg: Add support to handle MUX clocks drivers: clk: renesas: r9a07g044-cpg: Add ethernet clock sources drivers: clk: renesas: r9a07g044-cpg: Add GbEthernet clock/reset ravb: Replace chip type with a structure for driver data ravb: Factorise ptp feature ravb: Add features specific to R-Car Gen3 ravb: Add R-Car common features ravb: Factorise ravb_ring_free function ravb: Factorise ravb_ring_format function ravb: Factorise ravb_ring_init function ravb: Factorise {emac,dmac} init function ravb: Factorise ravb_rx function ravb: Factorise ravb_adjust_link function ravb: Factorise ravb_set_features ravb: Add reset support ravb: Add GbEthernet driver support arm64: dts: renesas: r9a07g044: Add GbEther nodes .../bindings/net/renesas,etheravb.yaml | 57 +- arch/arm64/boot/dts/renesas/r9a07g044.dtsi | 42 + drivers/clk/renesas/r9a07g044-cpg.c | 27 + drivers/clk/renesas/rzg2l-cpg.c | 24 + drivers/clk/renesas/rzg2l-cpg.h | 15 + drivers/net/ethernet/renesas/ravb.h | 112 ++- drivers/net/ethernet/renesas/ravb_main.c | 922 +++++++++++++++--- 7 files changed, 1031 insertions(+), 168 deletions(-) -- 2.17.1
