From: Arnd Bergmann <arnd@xxxxxxxx> Orinoco is a PIO-only ISA/PCMCIA 802.11b device with extra bus interface connections for PCI/Cardbus/mini-PCI and a few pre-2002 Apple PowerMac variants. It supports both wireless extensions and CFG80211, but I could not tell if it requires using both. This device used to be one of the most common ones 20 years ago, but has been orphaned for most of the time since then, and the conversion to cfg80211 has stalled in 2010.

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.
