2008-07-09[ARM] 5120/1: pxa: correct platform driver names for PXA25x and PXA27x UDC ↵Philipp Zabel
drivers The pxa2xx_udc.c driver is renamed to pxa25x_udc.c (the platform driver name changes from pxa2xx-udc to pxa25x-udc) and the platform driver name of pxa27x_udc.c is fixed to pxa27x-udc. pxa_device_udc in devices.c is split into pxa25x and pxa27x flavors and the pxa27x_device_udc is enabled in pxa27x.c.

and include pxa2xx-regs.h as build fix since PSSR definitions moved from pxa-regs.h into pxa2xx-regs.h.

2008-06-02[ARM] pxa: avoid kfreeing static data if platform device fails to registerRussell King
When a dynamically allocated platform device is 'put', the platform device's platform_data is kfree'd. This is bad if it's pointing at static data. Use the provided function to register platform data for these devices. This also means we can mark the pcmcia ops structures as __initdata. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-06-02[ARM] pxa: avoid registering multiple pxa2xx_pcmcia devicesRussell King
cm_x270 and mainstone both register their PCMCIA devices using the same name, resulting in a warning message from the kernel. Avoid this by making the cm_x270 and mainstone PCMCIA initialisation conditional on the machine type we're running on. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-05-19[ARM] pxa: separate PXA25x and PXA27x UDC register definitionsRussell King
The PXA25x and PXA27x USB device controller register definitions are different. Currently, they live side by side in pxa-regs.h, but only one set is available depending on the setting of PXA25x or PXA27x. This means that if we build to support both PXA25x and PXA27x, the PXA27x definitions are unavailable, even to PXA27x specific code. Remove these definitions from pxa-regs.h, and place them in separate files. Include these files where appropriate. Note: according to the dependencies in drivers/usb/gadget/Kconfig, we do not support the UDC on PXA27x nor PXA3xx CPUs, so remove the platform devices from pxa27x.c and pxa3xx.c.

2008-05-18i2c/max6875: Really prevent 24RF08 corruptionJean Delvare
i2c-core takes care of the possible corruption of 24RF08 chips for quite some times, so device devices no longer need to do it. And they really should not, as applying the prevention twice voids it.

2008-05-18i2c: Convert remaining new-style drivers to use module aliasingJean Delvare
Update all the remaining new-style i2c drivers to use standard module aliasing instead of the old driver_name/type driver matching scheme. Note that the tuner driver is a bit quirky at the moment, as it overwrites i2c_client.name with arbitrary strings. We write "tuner" back on remove, to make sure that driver cycling will work properly, but there may still be troublesome corner cases. Signed-off-by: Jean Delvare <khali@linux-fr.org>

There is a strange chip at 0x2e on the second SMBus channel of the DFI Lanparty NF4 Expert motherboard. Accessing the chip reboots the system. As there's nothing interesting on this SMBus channel, the easiest and safest thing to do is to disable it on that board.

2008-05-15Clean up 'print_fn_descriptor_symbol()' typesLinus Torvalds
Everybody wants to pass it a function pointer, and in fact, that is what you _must_ pass it for it to make sense (since it knows that ia64 and ppc64 use descriptors for function pointers and fetches the actual address from there).

2008-05-14Remove blkdev warning triggered by using mdNeil Brown
As setting and clearing queue flags now requires that we hold a spinlock on the queue, and as blk_queue_stack_limits is called without that lock, get the lock inside blk_queue_stack_limits. For blk_queue_stack_limits to be able to find the right lock, each md personality needs to set q->queue_lock to point to the appropriate lock. Those personalities which didn't previously use a spin_lock, us q->__queue_lock. So always initialise that lock when allocated. With this in place, setting/clearing of the QUEUE_FLAG_PLUGGED bit will no longer cause warnings as it will be clear that the proper lock is held. Thanks to Dan Williams for review and fixing the silly bugs.

2008-05-14lib: create common ascii hex arrayHarvey Harrison
Add a common hex array in hexdump.c so everyone can use it. Add a common hi/lo helper to avoid the shifting masking that is done to get the upper and lower nibbles of a byte value. Pull the pack_hex_byte helper from kgdb as it is opencoded many places in the tree that will be consolidated.
