Subject: [PATCH net-next v2 0/8] Add Gigabit Ethernet driver support
Date: Mon, 2 Aug 2021 11:26:46 +0100 [thread overview]
Message-ID: <20210802102654.5996-1-biju.das.jz@bp.renesas.com> (raw)
The DMAC and EMAC blocks of Gigabit Ethernet IP found on RZ/G2L SoC are
similar to the R-Car Ethernet AVB IP.
The Gigabit Ethernet IP consists of Ethernet controller (E-MAC), Internal
TCP/IP Offload Engine (TOE) and Dedicated Direct memory access controller
(DMAC).
With a few changes in the driver we can support both IPs.
Currently a runtime decision based on the chip type is used to distinguish
the HW differences between the SoC families.
This patch series is in preparation for supporting the RZ/G2L SoC by
replacing driver data chip type with struct ravb_hw_info by moving chip
type to it and also adding gstrings_stats, gstrings_size, net_hw_features,
net_features, num_gstat_queue, num_tx_desc, stats_len, skb_sz variables to
it. This patch also adds the feature bit for {RX, TX} clock internal
delays and TX Drop counters HW features found on R-Car Gen3 to struct
ravb_hw_info.
This patch series is based on net-next.
v1->v2:
* Replaced driver data chip type with struct ravb_hw_info
* Added gstrings_stats, gstrings_size, net_hw_features, net_features,
num_gstat_queue, num_tx_desc, stats_len, skb_sz to struct ravb_hw_info
* Added internal_delay and tx_drop_cntrs hw feature bit to struct ravb_hw_info
RFC->V1
* Incorporated feedback from Andrew, Sergei, Geert and Prabhakar
* https://patchwork.kernel.org/project/linux-renesas-soc/list/?series=515525
