This controller features two distinct Ethernet ports that can be independently operated. Reviewed-by: Simon Horman Signed-off-by: Florian Fainelli Signed-off-by: Justin Chen --- v9 - Reworked logic where a port fails to register during probe - Switch from array to linked list for interfaces. This simplifies the logic and makes it a bit cleaner to follow. - Check for case where remove and shutdown hook both get called. - Use skb_cow_head instead of skb_realloc_headroom - Add ratelimit for some err prints. - Use napi_alloc_skb instead of __netdev_alloc_skb(). - Reworked some rtnl_link_stats64 according to documentation. v8 - Address some checkpatch warnings v7 - Fixed leaking ports_node device node. - Split out to smaller commits v6 - Fixed a reserved mac filter indexing error - Removed tx_lock - Simplified tx_timeout hook - Removed get_stats - Fixed phy ioctl - Fixed dev -> ndev typo - Fixed set_wol double disable v5 - Remove unnecessary parenthesis - Use bool for bcmasp_netfilt_check_dup() v4 - Address sparse warnings - Fix one more reverse xmas tree violation - Improve error logic for bcmasp_netfilt_get_reg_offset() - Remove inlines v3 - Fix logic error with net stats where some stats were missing - General clean up addressing formatting/spelling/consistency - Use dev_err_probe to save a few LoCs - Use put_unaligned when updating net stats v2 - Replace a couple functions with helper functions - Fix a few WoL issues drivers/net/ethernet/broadcom/Kconfig | 11 + drivers/net/ethernet/broadcom/Makefile | 1 + drivers/net/ethernet/broadcom/asp2/Makefile | 2 + drivers/net/ethernet/broadcom/asp2/bcmasp.c | 696 ++++++++++ drivers/net/ethernet/broadcom/asp2/bcmasp.h | 503 ++++++++ .../net/ethernet/broadcom/asp2/bcmasp_ethtool.c | 40 + drivers/net/ethernet/broadcom/asp2/bcmasp_intf.c | 1342 ++++++++++++++++++++ .../net/ethernet/broadcom/asp2/bcmasp_intf_defs.h | 196 +++ 8 files changed, 2791 insertions(+) create mode 100644 drivers/net/ethernet/broadcom/asp2/Makefile create mode 100644 drivers/net/ethernet/broadcom/asp2/bcmasp.c create mode 100644 drivers/net/ethernet/broadcom/asp2/bcmasp.h create mode 100644 drivers/net/ethernet/broadcom/asp2/bcmasp_ethtool.c create mode 100644 drivers/net/ethernet/broadcom/asp2/bcmasp_intf.c create mode 100644 drivers/net/ethernet/broadcom/asp2/bcmasp_intf_defs.h diff --git a/drivers/net/ethernet/broadcom/Kconfig b/drivers/net/ethernet/broadcom/Kconfig index 948586bf1b5b..d4166141145d 100644 --- a/drivers/net/ethernet/broadcom/Kconfig +++ b/drivers/net/ethernet/broadcom/Kconfig @@ -255,4 +255,15 @@ config BNXT_HWMON Say Y if you want to expose the thermal sensor data on NetXtreme-C/E devices, via the hwmon sysfs interface. +config BCMASP + tristate "Broadcom ASP 2.0 Ethernet support" + default ARCH_BRCMSTB + depends on OF + select MII + select PHYLIB + select MDIO_BCM_UNIMAC + help + This configuration enables the Broadcom ASP 2.0 Ethernet controller + driver which is present in Broadcom STB SoCs such as 72165. + endif # NET_VENDOR_BROADCOM diff --git a/drivers/net/ethernet/broadcom/Makefile b/drivers/net/ethernet/broadcom/Makefile index 0ddfb5b5d53c..bac5cb6ad0cd 100644 --- a/drivers/net/ethernet/broadcom/Makefile +++ b/drivers/net/ethernet/broadcom/Makefile @@ -17,3 +17,4 @@ obj-$(CONFIG_BGMAC_BCMA) += bgmac-bcma.o bgmac-bcma-mdio.o obj-$(CONFIG_BGMAC_PLATFORM) += bgmac-platform.o obj-$(CONFIG_SYSTEMPORT) += bcmsysport.o obj-$(CONFIG_BNXT) += bnxt/ +obj-$(CONFIG_BCMASP) += asp2/ diff --git a/drivers/net/ethernet/broadcom/asp2/Makefile b/drivers/net/ethernet/broadcom/asp2/Makefile new file mode 100644 index 000000000000..e07550315f83 --- /dev/null +++ b/drivers/net/ethernet/broadcom/asp2/Makefile @@ -0,0 +1,2 @@ +obj-$(CONFIG_BCMASP) += bcm-asp.o +bcm-asp-objs := bcmasp.o bcmasp_intf.o bcmasp_ethtool.o diff --git a/drivers/net/ethernet/broadcom/asp2/bcmasp.c b/drivers/net/ethernet/broadcom/asp2/bcmasp.c new file mode 100644 index 000000000000..83494641b545 --- /dev/null +++ b/drivers/net/ethernet/broadcom/asp2/bcmasp.c @@ -0,0 +1,696 @@ +// SPDX-License-Identifier: GPL-2.0 +/* + * Broadcom STB ASP 2.0 Driver + * + * Copyright (c) 2023 Broadcom + */ +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include +#include + +#include "bcmasp.h" +#include "bcmasp_intf_defs.h" + +static void _intr2_mask_clear(struct bcmasp_priv *priv, u32 mask) +{ + intr2_core_wl(priv, mask, ASP_INTR2_MASK_CLEAR);
