logic_pio_trans

函数名称：logic_pio_trans_hwaddr - translate HW address to logical PIO*@fwnode: FW node reference for the host*@addr: Host-relative HW address*@size: size to translate* Returns Logical PIO value if successful, ~0UL otherwise

函数原型：unsigned long logic_pio_trans_hwaddr(struct fwnode_handle *fwnode, resource_size_t addr, resource_size_t size)

返回类型：unsigned long

参数：

类型	参数	名称
struct fwnode_handle *	fwnode
resource_size_t	addr
resource_size_t	size

194

range等于d_io_range_by_fwnode - find logical PIO range for given FW node*@fwnode: FW node handle associated with logical PIO range* Returns pointer to node on success, NULL otherwise.* Traverse the io_range_list to find the registered node for @fwnode.

195

如果非range或flags恒等于LOGIC_PIO_CPU_MMIO则

196

打印错误信息("IO range not found or invalid\n")

197

返回:0UL的反

199

如果 range size populated 小于size则

200

打印错误信息("resource size %pa cannot fit in IO range size %pa\n", & size, & range size populated )

202

返回:0UL的反

204

返回:addr减hw_start加io_start
