From db0f04f324b3a9a317af2f050397c1dfa903eefa Mon Sep 17 00:00:00 2001 From: Lorenzo Bianconi Date: Sun, 9 Sep 2018 22:32:37 +0200 Subject: [PATCH] mt76: add mt76_mcu_ops data structure for mcu related pointers Introduce mt76_mcu_ops data structure to contain mcu related function pointers. This is a preliminary patch to move mt76x02 usb mcu code in mt76x02-usb module Acked-by: Stanislaw Gruszka Signed-off-by: Lorenzo Bianconi Signed-off-by: Felix Fietkau --- drivers/net/wireless/mediatek/mt76/mt76.h | 11 +++++++++++ drivers/net/wireless/mediatek/mt76/usb.c | 1 + drivers/net/wireless/mediatek/mt76/usb_mcu.c | 10 ++++++++++ 3 files changed, 22 insertions(+) diff --git a/drivers/net/wireless/mediatek/mt76/mt76.h b/drivers/net/wireless/mediatek/mt76/mt76.h index 2d74a2c3d93c..bff03470ccbc 100644 --- a/drivers/net/wireless/mediatek/mt76/mt76.h +++ b/drivers/net/wireless/mediatek/mt76/mt76.h @@ -119,6 +119,12 @@ struct mt76_queue { struct sk_buff *rx_head; }; +struct mt76_mcu_ops { + struct sk_buff *(*mcu_msg_alloc)(const void *data, int len); + int (*mcu_send_msg)(struct mt76_dev *dev, struct sk_buff *skb, + int cmd, bool wait_resp); +}; + struct mt76_queue_ops { int (*init)(struct mt76_dev *dev); @@ -336,6 +342,7 @@ struct mt76_dev { const struct mt76_bus_ops *bus; const struct mt76_driver_ops *drv; + const struct mt76_mcu_ops *mcu_ops; void __iomem *regs; struct device *dev; @@ -436,6 +443,9 @@ struct mt76_rx_status { #define mt76_rmw(dev, ...)
