From 4e35e80750b33727e606be9e7ce447bde2e0deb7 Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Tue, 7 Mar 2023 15:55:35 +0000 Subject: [PATCH 3/7] net: ethernet: mtk_eth_soc: rely on num_devs and remove MTK_MAC_COUNT Get rid of MTK_MAC_COUNT since it is a duplicated of eth->soc->num_devs. Signed-off-by: Lorenzo Bianconi Signed-off-by: Daniel Golle --- drivers/net/ethernet/mediatek/mtk_eth_soc.c | 30 ++++++++++----------- drivers/net/ethernet/mediatek/mtk_eth_soc.h | 1 - 2 files changed, 15 insertions(+), 16 deletions(-) --- a/drivers/net/ethernet/mediatek/mtk_eth_soc.c +++ b/drivers/net/ethernet/mediatek/mtk_eth_soc.c @@ -944,7 +944,7 @@ static void mtk_stats_update(struct mtk_ { int i; - for (i = 0; i < MTK_MAC_COUNT; i++) { + for (i = 0; i < eth->soc->num_devs; i++) { if (!eth->mac[i] || !eth->mac[i]->hw_stats) continue; if (spin_trylock(ð->mac[i]->hw_stats->stats_lock)) { @@ -1449,7 +1449,7 @@ static int mtk_queue_stopped(struct mtk_ { int i; - for (i = 0; i < MTK_MAC_COUNT; i++) { + for (i = 0; i < eth->soc->num_devs; i++) { if (!eth->netdev[i]) continue; if (netif_queue_stopped(eth->netdev[i])) @@ -1463,7 +1463,7 @@ static void mtk_wake_queue(struct mtk_et { int i; - for (i = 0; i < MTK_MAC_COUNT; i++) { + for (i = 0; i < eth->soc->num_devs; i++) { if (!eth->netdev[i]) continue; netif_tx_wake_all_queues(eth->netdev[i]); @@ -1956,7 +1956,7 @@ static int mtk_poll_rx(struct napi_struc !(trxd.rxd4 & RX_DMA_SPECIAL_TAG)) mac = RX_DMA_GET_SPORT(trxd.rxd4) - 1; - if (unlikely(mac < 0 || mac >= MTK_MAC_COUNT || + if (unlikely(mac < 0 || mac >= eth->soc->num_devs || !eth->netdev[mac])) goto release_desc; @@ -2993,7 +2993,7 @@ static void mtk_dma_free(struct mtk_eth const struct mtk_soc_data *soc = eth->soc; int i; - for (i = 0; i < MTK_MAC_COUNT; i++) + for (i = 0; i < soc->num_devs; i++) if (eth->netdev[i]) netdev_reset_queue(eth->netdev[i]); if (eth->scratch_ring) { @@ -3147,7 +3147,7 @@ static void mtk_gdm_config(struct mtk_et if (MTK_HAS_CAPS(eth->soc->caps, MTK_SOC_MT7628)) return; - for (i = 0; i < MTK_MAC_COUNT; i++) { + for (i = 0; i < eth->soc->num_devs; i++) { u32 val = mtk_r32(eth, MTK_GDMA_FWD_CFG(i)); /* default setup the forward port to send frame to PDMA */ @@ -3758,7 +3758,7 @@ static int mtk_hw_init(struct mtk_eth *e * up with the more appropriate value when mtk_mac_config call is being * invoked. */ - for (i = 0; i < MTK_MAC_COUNT; i++) { + for (i = 0; i < eth->soc->num_devs; i++) { struct net_device *dev = eth->netdev[i]; mtk_w32(eth, MAC_MCR_FORCE_LINK_DOWN, MTK_MAC_MCR(i)); @@ -3963,7 +3963,7 @@ static void mtk_pending_work(struct work mtk_prepare_for_reset(eth); /* stop all devices to make sure that dma is properly shut down */ - for (i = 0; i < MTK_MAC_COUNT; i++) { + for (i = 0; i < eth->soc->num_devs; i++) { if (!eth->netdev[i] || !netif_running(eth->netdev[i])) continue; @@ -3979,7 +3979,7 @@ static void mtk_pending_work(struct work mtk_hw_init(eth, true); /* restart DMA and enable IRQs */ - for (i = 0; i < MTK_MAC_COUNT; i++) { + for (i = 0; i < eth->soc->num_devs; i++) { if (!test_bit(i, &restart)) continue; @@ -4007,7 +4007,7 @@ static int mtk_free_dev(struct mtk_eth * { int i; - for (i = 0; i < MTK_MAC_COUNT; i++) { + for (i = 0; i < eth->soc->num_devs; i++) { if (!eth->netdev[i]) continue; free_netdev(eth->netdev[i]); @@ -4026,7 +4026,7 @@ static int mtk_unreg_dev(struct mtk_eth { int i; - for (i = 0; i < MTK_MAC_COUNT; i++) { + for (i = 0; i < eth->soc->num_devs; i++) { struct mtk_mac *mac; if (!eth->netdev[i]) continue; @@ -4331,7 +4331,7 @@ static int mtk_add_mac(struct mtk_eth *e } id = be32_to_cpup(_id); - if (id >= MTK_MAC_COUNT) { + if (id >= eth->soc->num_devs) { dev_err(eth->dev, "%d is not a valid mac id\n", id); return -EINVAL; } @@ -4461,7 +4461,7 @@ void mtk_eth_set_dma_device(struct mtk_e rtnl_lock(); - for (i = 0; i < MTK_MAC_COUNT; i++) { + for (i = 0; i < eth->soc->num_devs; i++) { dev = eth->netdev[i]; if (!dev || !(dev->flags & IFF_UP)) @@ -4787,7 +4787,7 @@ static int mtk_remove(struct platform_de int i; /* stop all devices to make sure that dma is properly shut down */ - for (i = 0; i < MTK_MAC_COUNT; i++) { + for (i = 0; i < eth->soc->num_devs; i++) { if (!eth->netdev[i]) continue; mtk_stop(eth->netdev[i]); --- a/drivers/net/ethernet/mediatek/mtk_eth_soc.h +++ b/drivers/net/ethernet/mediatek/mtk_eth_soc.h @@ -33,7 +33,6 @@ #define MTK_TX_DMA_BUF_LEN_V2 0xffff #define MTK_QDMA_RING_SIZE 2048 #define MTK_DMA_SIZE 512 -#define MTK_MAC_COUNT 2 #define MTK_RX_ETH_HLEN (VLAN_ETH_HLEN + ETH_FCS_LEN) #define MTK_RX_HLEN (NET_SKB_PAD + MTK_RX_ETH_HLEN + NET_IP_ALIGN) #define MTK_DMA_DUMMY_DESC 0xffffffff
