23 Abstract: Data structures for the rt2x00pci module.
32 * This variable should be used with the
33 * pci_driver structure initialization.
35 #define PCI_DEVICE_DATA(__ops) .driver_data = (kernel_ulong_t)(__ops)
40 static inline void rt2x00pci_register_read(struct rt2x00_dev *rt2x00dev,
41 const unsigned int offset,
44 *value = readl(rt2x00dev->csr.base + offset);
47 static inline void rt2x00pci_register_multiread(struct rt2x00_dev *rt2x00dev,
48 const unsigned int offset,
49 void *value, const u32 length)
51 memcpy_fromio(value, rt2x00dev->csr.base + offset, length);
54 static inline void rt2x00pci_register_write(struct rt2x00_dev *rt2x00dev,
55 const unsigned int offset,
58 writel(value, rt2x00dev->csr.base + offset);
61 static inline void rt2x00pci_register_multiwrite(struct rt2x00_dev *rt2x00dev,
62 const unsigned int offset,
66 memcpy_toio(rt2x00dev->csr.base + offset, value, length);
70 * rt2x00pci_regbusy_read - Read from register with busy check
71 * @rt2x00dev: Device pointer, see &struct rt2x00_dev.
72 * @offset: Register offset
73 * @field: Field to check if register is busy
74 * @reg: Pointer to where register contents should be stored
76 * This function will read the given register, and checks if the
77 * register is busy. If it is, it will sleep for a couple of
78 * microseconds before reading the register again. If the register
79 * is not read after a certain timeout, this function will return
82 int rt2x00pci_regbusy_read(struct rt2x00_dev *rt2x00dev,
83 const unsigned int offset,
84 const struct rt2x00_field32 field,
88 * rt2x00pci_write_tx_data - Initialize data for TX operation
89 * @entry: The entry where the frame is located
91 * This function will initialize the DMA and skb descriptor
92 * to prepare the entry for the actual TX operation.
94 int rt2x00pci_write_tx_data(struct queue_entry *entry);
97 * struct queue_entry_priv_pci: Per entry PCI specific information
99 * @desc: Pointer to device descriptor
100 * @desc_dma: DMA pointer to &desc.
101 * @data: Pointer to device's entry memory.
102 * @data_dma: DMA pointer to &data.
104 struct queue_entry_priv_pci {
110 * rt2x00pci_rxdone - Handle RX done events
111 * @rt2x00dev: Device pointer, see &struct rt2x00_dev.
113 void rt2x00pci_rxdone(struct rt2x00_dev *rt2x00dev);
116 * Device initialization handlers.
118 int rt2x00pci_initialize(struct rt2x00_dev *rt2x00dev);
119 void rt2x00pci_uninitialize(struct rt2x00_dev *rt2x00dev);
122 * PCI driver handlers.
