The patch makes use of the +plat_nand driver. As with the EBU NOR driver merged in 3.0, we have the +endianess swap problem on read. To workaround this problem we make the +read_byte() callback available via the plat_nand driver causing the nand +layer to do byte reads. + +Signed-off-by: John Crispin <blogic@openwrt.org> + +TODO :

This module will be dynamically installed ++ * after Linux is booted using the insmod command. When the module is ++ * installed, the dwc_otg_init function is called. When the module is ++ * removed (using rmmod), the dwc_otg_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 lm_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/gpio.h> ++ ++#include <linux/device.h> ++#include <linux/platform_device.h> ++ ++#include <linux/errno.h> ++#include <linux/types.h> ++#include <linux/stat.h> /* permission constants */ ++#include <linux/irq.h> ++#include <asm/io.h> ++ ++#include "dwc_otg_plat.h" ++#include "dwc_otg_attr.h" ++#include "dwc_otg_driver.h" ++#include "dwc_otg_cil.h" ++#include "dwc_otg_cil_ifx.h" ++ ++// #include "dwc_otg_pcd.h" // device ++#include "dwc_otg_hcd.h" // host ++ ++#include "dwc_otg_ifx.h" // for Infineon platform specific. ++ ++#define DWC_DRIVER_VERSION "2.60a 22-NOV-2006" ++#define DWC_DRIVER_DESC "HS OTG USB Controller driver" ++ ++const char dwc_driver_name[] = "dwc_otg"; ++ ++static unsigned long dwc_iomem_base = IFX_USB_IOMEM_BASE; ++int dwc_irq = LTQ_USB_INT; ++//int dwc_irq = 54; ++//int dwc_irq = IFXMIPS_USB_OC_INT; ++ ++extern int ifx_usb_hc_init(unsigned long base_addr, int irq); ++extern void ifx_usb_hc_remove(void); ++ ++/*-------------------------------------------------------------------------*/ ++/* Encapsulate the module parameter settings */ ++ ++static dwc_otg_core_params_t dwc_otg_module_params = { ++ .opt = -1, ++ .otg_cap = -1, ++ .dma_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, ++}; ++ ++/** ++ * 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 = 0xff; /* 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.

The transfer may be broken ++ // up into chunks according to the current maximum packet size ++ // for the endpoint, which is a function of the configuration ++ // and is encoded in the pipe. When the length is zero, neither ++ // transfer_buffer nor transfer_dma is used. ++ //actual_length This is read in non-iso completion functions, and it tells ++ // how many bytes (out of transfer_buffer_length) were transferred. ++ // It will normally be the same as requested, unless either an error ++ // was reported or a short read was performed.

The gpio driver needs a hack +at 2 places to make the different register layout of the GPIO3 work properly +with the driver. Before only GPIO0-2 were supported. As the GPIO number scheme +clashes with the new size, we also move the other gpio chips to new offsets. + +Signed-off-by: John Crispin <blogic@openwrt.org> +Signed-off-by: Thomas Langer
