If you do not delete the - * provisions above, a recipient may use your version of this file - * under either the MPL or the GPL. - * - * Here's the general details on how the PLX9052 adapter works: - * - * - Two PCI I/O address spaces, one 0x80 long which contains the - * PLX9052 registers, and one that's 0x40 long mapped to the PCMCIA - * slot I/O address space. - * - * - One PCI memory address space, mapped to the PCMCIA attribute space - * (containing the CIS). - * - * Using the later, you can read through the CIS data to make sure the - * card is compatible with the driver. Keep in mind that the PCMCIA - * spec specifies the CIS as the lower 8 bits of each word read from - * the CIS, so to read the bytes of the CIS, read every other byte - * (0,2,4,...). Passing that test, you need to enable the I/O address - * space on the PCMCIA card via the PCMCIA COR register. This is the - * first byte following the CIS. In my case (which may not have any - * relation to what's on the PRISM2 cards), COR was at offset 0x800 - * within the PCI memory space. Write 0x41 to the COR register to - * enable I/O mode and to select level triggered interrupts. To - * confirm you actually succeeded, read the COR register back and make - * sure it actually got set to 0x41, in case you have an unexpected - * card inserted. - * - * Following that, you can treat the second PCI I/O address space (the - * one that's not 0x80 in length) as the PCMCIA I/O space. - * - * Note that in the Eumitcom's source for their drivers, they register - * the interrupt as edge triggered when registering it with the - * Windows kernel. I don't recall how to register edge triggered on - * Linux (if it can be done at all). But in some experimentation, I - * don't see much operational difference between using either - * interrupt mode. Don't mess with the interrupt mode in the COR - * register though, as the PLX9052 wants level triggers with the way - * the serial EEPROM configures it on the WL11000. - * - * There's some other little quirks related to timing that I bumped - * into, but I don't recall right now. Also, there's two variants of - * the WL11000 I've seen, revision A1 and T2. These seem to differ - * slightly in the timings configured in the wait-state generator in - * the PLX9052. There have also been some comments from Eumitcom that - * cards shouldn't be hot swapped, apparently due to risk of cooking - * the PLX9052. I'm unsure why they believe this, as I can't see - * anything in the design that would really cause a problem, except - * for crashing drivers not written to expect it. And having developed - * drivers for the WL11000, I'd say it's quite tricky to write code - * that will successfully deal with a hot unplug. Very odd things - * happen on the I/O side of things. But anyway, be warned. Despite - * that, I've hot-swapped a number of times during debugging and - * driver development for various reasons (stuck WAIT# line after the - * radio card's firmware locks up). - */ - -#define DRIVER_NAME "orinoco_plx" -#define PFX DRIVER_NAME ": " - -#include <linux/module.h> -#include <linux/kernel.h> -#include <linux/init.h> -#include <linux/delay.h> -#include <linux/pci.h> -#include <pcmcia/cisreg.h> - -#include "orinoco.h" -#include "orinoco_pci.h" - -#define COR_OFFSET (0x3e0) /* COR attribute offset of Prism2 PC card */ -#define COR_VALUE (COR_LEVEL_REQ | COR_FUNC_ENA) /* Enable PC card with interrupt in level trigger */ -#define COR_RESET (0x80) /* reset bit in the COR register */ -#define PLX_RESET_TIME (500) /* milliseconds */ - -#define PLX_INTCSR 0x4c /* Interrupt Control & Status Register */ -#define PLX_INTCSR_INTEN (1 << 6) /* Interrupt Enable bit */ - -/* - * Do a soft reset of the card using the Configuration Option Register - */ -static int orinoco_plx_cor_reset(struct orinoco_private *priv) -{ - struct hermes *hw = &priv->hw; - struct orinoco_pci_card *card = priv->card; - unsigned long timeout; - u16 reg; - - iowrite8(COR_VALUE | COR_RESET, card->attr_io + COR_OFFSET); - mdelay(1); - - iowrite8(COR_VALUE, card->attr_io + COR_OFFSET); - mdelay(1); - - /* Just in case, wait more until the card is no longer busy */ - timeout = jiffies + msecs_to_jiffies(PLX_RESET_TIME); - reg = hermes_read_regn(hw, CMD); - while (time_before(jiffies, timeout) && (reg & HERMES_CMD_BUSY)) { - mdelay(1); - reg = hermes_read_regn(hw, CMD); - } - - /* Still busy? */ - if (reg & HERMES_CMD_BUSY) { - printk(KERN_ERR PFX "Busy timeout\n"); - return -ETIMEDOUT; - } - - return 0; -} - -static int orinoco_plx_hw_init(struct orinoco_pci_card *card) -{ - int i; - u32 csr_reg; - static const u8 cis_magic[] = { - 0x01, 0x03, 0x00, 0x00, 0xff, 0x17, 0x04, 0x67 - }; - - printk(KERN_DEBUG PFX "CIS: "); - for (i = 0; i < 16; i++) - printk("%02X:", ioread8(card->attr_io + (i << 1))); - printk("\n"); - - /* Verify whether a supported PC card is present */ - /* FIXME: we probably need to be smarted about this */ - for (i = 0; i < sizeof(cis_magic); i++) { - if (cis_magic[i] != ioread8(card->attr_io + (i << 1))) { - printk(KERN_ERR PFX "The CIS value of Prism2 PC " - "card is unexpected\n"); - return -ENODEV; - } - } - - /* bjoern: We need to tell the card to enable interrupts, in - case the serial eprom didn't do this already.
