From 81f280e22f14d6d976620acaa1b346a90f4e1adc Mon Sep 17 00:00:00 2001 From: Richard Purdie Date: Sat, 12 Nov 2005 14:22:11 +0000 Subject: [PATCH] USB: pxa27x OHCI - Separate platform code from main driver To allow multiple platforms to use the PXA27x OHCI driver, the platform code needs to be moved into the board specific files in arch/arm/mach-pxa. This patch does this for mainstone and adds preliminary hooks to allow other boards to use the driver. This has been compile tested for mainstone and successfully run on Spitz (Sharp Zaurus SL-C3000) with the addition of an appropriate board support file.

The changes are confined to the core, except that the usb_trylock_device routine now uses the return convention of down_trylock rather than down_read_trylock (they return opposite values for no good reason). A couple of other associated changes are included as well: Now that we aren't concerned about HCDs that avoid using the hcd glue layer, usb_disconnect no longer needs to acquire the usb_bus_lock -- that can be done by usb_remove_hcd where it belongs. Devices aren't locked over the same scope of code in usb_new_device and hub_port_connect_change as they used to be. This shouldn't cause any trouble. Along with the preceding driver core patch, this needs a lot of testing.

(This is something we should have been doing all along.) A new field in struct usb_device holds the amount of bus current available from the upstream port, and the usb_hub structure keeps track of the current available for each downstream port. Two new rules for configuration selection are added: Don't select a self-powered configuration when only bus power is available. Don't select a configuration requiring more bus power than is available. However the first rule is #if-ed out, because I found that the internal hub in my HP USB keyboard claims that its only configuration is self-powered. The rule would prevent the configuration from being chosen, leaving the hub & keyboard unconfigured. Since similar descriptor errors may turn out to be fairly common, it seemed wise not to include a rule that would break automatic configuration unnecessarily for such devices. The second rule may also trigger unnecessarily, although this should be less common. More likely it will annoy people by sometimes failing to accept configurations that should never have been chosen in the first place. The patch also changes usbcore's reaction when no configuration is suitable. Instead of raising an error and rejecting the device, now the core will simply leave the device unconfigured. People can always work around such problems by installing configurations manually through sysfs.

The original patch has been reformed by me, as it clashed with the libusual patches.
