The FU740 ethernet controller uses the same management IP block as the FU540, which is tightly coupled with the Cadence MACB IP and manages boundary signals. To avoid code duplication while maintaining distinct SoC identification, this patch: - Renames sifive_fu540_macb_mgmt to sifive_macb_mgmt to reflect that it's shared between FU540 and FU740 - Adds a fu740_c000_config structure that reuses the FU540 initialization functions - Follows the established pattern in this driver where multiple SoC configs share the same init functions Signed-off-by: Max Hsu --- drivers/net/ethernet/cadence/macb_main.c | 17 ++++++++++++++--- 1 file changed, 14 insertions(+), 3 deletions(-) diff --git a/drivers/net/ethernet/cadence/macb_main.c b/drivers/net/ethernet/cadence/macb_main.c index 43cd013bb70e..10d049391a73 100644 --- a/drivers/net/ethernet/cadence/macb_main.c +++ b/drivers/net/ethernet/cadence/macb_main.c @@ -39,8 +39,8 @@ #include #include "macb.h" -/* This structure is only used for MACB on SiFive FU540 devices */ -struct sifive_fu540_macb_mgmt { +/* This structure is used for MACB on SiFive FU540/FU740 devices */ +struct sifive_macb_mgmt { void __iomem *reg; unsigned long rate; struct clk_hw hw; @@ -4650,7 +4650,7 @@ static const struct macb_usrio_config macb_default_usrio = { /* max number of receive buffers */ #define AT91ETHER_MAX_RX_DESCR 9 -static struct sifive_fu540_macb_mgmt *mgmt; +static struct sifive_macb_mgmt *mgmt; static int at91ether_alloc_coherent(struct macb *lp) { @@ -5236,6 +5236,16 @@ static const struct macb_config fu540_c000_config = { .usrio = &macb_default_usrio, }; +static const struct macb_config fu740_c000_config = { + .caps = MACB_CAPS_GIGABIT_MODE_AVAILABLE | MACB_CAPS_JUMBO | + MACB_CAPS_GEM_HAS_PTP, + .dma_burst_length = 16, + .clk_init = fu540_c000_clk_init, + .init = fu540_c000_init, + .jumbo_max_len = 10240, + .usrio = &macb_default_usrio, +}; + static const struct macb_config at91sam9260_config = { .caps = MACB_CAPS_USRIO_HAS_CLKEN | MACB_CAPS_USRIO_DEFAULT_IS_MII_GMII, .clk_init = macb_clk_init, @@ -5411,6 +5421,7 @@ static const struct of_device_id macb_dt_ids[] = { { .compatible = "cdns,zynqmp-gem", .data = &zynqmp_config}, /* deprecated */ { .compatible = "cdns,zynq-gem", .data = &zynq_config }, /* deprecated */ { .compatible = "sifive,fu540-c000-gem", .data = &fu540_c000_config }, + { .compatible = "sifive,fu740-c000-gem", .data = &fu740_c000_config }, { .compatible = "microchip,mpfs-macb", .data = &mpfs_config }, { .compatible = "microchip,sama7g5-gem", .data = &sama7g5_gem_config }, { .compatible = "microchip,sama7g5-emac", .data = &sama7g5_emac_config }, -- 2.43.0
