This module will be dynamically installed - * after Linux is booted using the insmod command. When the module is - * installed, the dwc_otg_driver_init function is called. When the module is - * removed (using rmmod), the dwc_otg_driver_cleanup function is called. - * - * This module also defines a data structure for the dwc_otg_driver, which is - * used in conjunction with the standard ARM platform_device structure. These - * structures allow the OTG driver to comply with the standard Linux driver - * model in which devices and drivers are registered with a bus driver. This - * has the benefit that Linux can expose attributes of the driver and device - * in its special sysfs file system. Users can then read or write files in - * this file system to perform diagnostics on the driver components or the - * device. - */ - -#include <linux/kernel.h> -#include <linux/module.h> -#include <linux/moduleparam.h> -#include <linux/init.h> -#include <linux/device.h> -#include <linux/errno.h> -#include <linux/types.h> -#include <linux/stat.h> /* permission constants */ -#include <linux/version.h> -#include <linux/platform_device.h> - -#if LINUX_VERSION_CODE >= KERNEL_VERSION(2,6,20) -# include <linux/irq.h> -#endif - -#include <asm/io.h> - -#if LINUX_VERSION_CODE < KERNEL_VERSION(2,6,20) -# include <asm/irq.h> -#endif - -#include "linux/dwc_otg_plat.h" -#include "dwc_otg_attr.h" -#include "dwc_otg_driver.h" -#include "dwc_otg_cil.h" -#include "dwc_otg_pcd.h" -#include "dwc_otg_hcd.h" - -#define DWC_DRIVER_VERSION "2.72a 24-JUN-2008" -#define DWC_DRIVER_DESC "HS OTG USB Controller driver" - -static const char dwc_driver_name[] = "dwc_otg"; - -/*-------------------------------------------------------------------------*/ -/* Encapsulate the module parameter settings */ - -static dwc_otg_core_params_t dwc_otg_module_params = { - .opt = -1, - .otg_cap = -1, - .dma_enable = -1, - .dma_desc_enable = -1, - .dma_burst_size = -1, - .speed = -1, - .host_support_fs_ls_low_power = -1, - .host_ls_low_power_phy_clk = -1, - .enable_dynamic_fifo = -1, - .data_fifo_size = -1, - .dev_rx_fifo_size = -1, - .dev_nperio_tx_fifo_size = -1, - .dev_perio_tx_fifo_size = { - /* dev_perio_tx_fifo_size_1 */ - -1, - -1, - -1, - -1, - -1, - -1, - -1, - -1, - -1, - -1, - -1, - -1, - -1, - -1, - -1 - /* 15 */ - }, - .host_rx_fifo_size = -1, - .host_nperio_tx_fifo_size = -1, - .host_perio_tx_fifo_size = -1, - .max_transfer_size = -1, - .max_packet_count = -1, - .host_channels = -1, - .dev_endpoints = -1, - .phy_type = -1, - .phy_utmi_width = -1, - .phy_ulpi_ddr = -1, - .phy_ulpi_ext_vbus = -1, - .i2c_enable = -1, - .ulpi_fs_ls = -1, - .ts_dline = -1, - .en_multiple_tx_fifo = -1, - .dev_tx_fifo_size = { - /* dev_tx_fifo_size */ - -1, - -1, - -1, - -1, - -1, - -1, - -1, - -1, - -1, - -1, - -1, - -1, - -1, - -1, - -1 - /* 15 */ - }, - .thr_ctl = -1, - .tx_thr_length = -1, - .rx_thr_length = -1, - .pti_enable = -1, - .mpi_enable = -1, -}; - -/** - * This function shows the Driver Version. - */ -static ssize_t version_show(struct device_driver *dev, char *buf) -{ - return snprintf(buf, sizeof(DWC_DRIVER_VERSION)+2, "%s\n", - DWC_DRIVER_VERSION); -} -static DRIVER_ATTR(version, S_IRUGO, version_show, NULL); - -/** - * Global Debug Level Mask. - */ -uint32_t g_dbg_lvl = 0; /* OFF */ - -/** - * This function shows the driver Debug Level. - */ -static ssize_t dbg_level_show(struct device_driver *drv, char *buf) -{ - return sprintf(buf, "0x%0x\n", g_dbg_lvl); -} - -/** - * This function stores the driver Debug Level. - */ -static ssize_t dbg_level_store(struct device_driver *drv, const char *buf, - size_t count) -{ - g_dbg_lvl = simple_strtoul(buf, NULL, 16); - return count; -} -static DRIVER_ATTR(debuglevel, S_IRUGO|S_IWUSR, dbg_level_show, dbg_level_store); - -/** - * This function is called during module intialization to verify that - * the module parameters are in a valid state. - */ -static int check_parameters(dwc_otg_core_if_t *core_if) -{ - int i; - int retval = 0; - -/* Checks if the parameter is outside of its valid range of values */ -#define DWC_OTG_PARAM_TEST(_param_, _low_, _high_) \ - ((dwc_otg_module_params._param_ < (_low_)) || \ - (dwc_otg_module_params._param_ > (_high_))) - -/* If the parameter has been set by the user, check that the parameter value is - * within the value range of values.
