Staging: Panel: prevent driver from calling misc_deregister twice on same ressource

2009-10-30T21:47:43+00:00

This patch prevents the driver from calling misc_deregister twice on the same ressouce when unloading the driver. Unloading the driver without this patch results in a Kernel BUG like this: Panel driver version 0.9.5 registered on parport0 (io=0x378). BUG: unable to handle kernel paging request at 0000000000100108 IP: [] misc_deregister+0x2d/0x90 PGD 6caff067 PUD 762b7067 PMD 0 Oops: 0002 [#1] PREEMPT SMP last sysfs file: /sys/devices/platform/w83627hf.656/in8_input ... This patch fixes this issue, although maybe not in the best way possible :) linux version v2.6.32-rc1 - linus git tree, Di 29.

Staging: panel: Add support for TI CLCD interface

2009-09-15T19:02:29+00:00

On TI DA850/OMAP-L138 EVM, HD44780 (24x2) LCD panel is being used[1], but it is interfaced through the SoC specific LCD interface and not through parallel port. A parallel port driver has been developed which interfaces to the panel driver through the SoC specific LCD interface. Basically, both the serial and parallel interfaces supported by the panel driver do not suit the specific interface SoC is supporting so, a new interface type has been introduced. Ideally the panel driver should be de-coupled from parallel and serial port related items but this patch is something that can be merged in the meantime.

Staging: panel: remove support for smartcards

2009-01-06T21:52:30+00:00

Smartcard support was more like a proof-of-concept than a completed work. It was only able to read serial numbers from a few smartcards, and the goal was to be able to secure keypad access with a smartcard. Given how the concept was limited, this was never used beyond demos, and it's better to remove this code so that nobody tries to use it for security purposes. The function panel_bind_callback() was ifdef'ed out, as its only user was smartcard. However, it would be a waste to remove it because many variations made on this driver will need it.

Staging: panel: remove ifdefs and code for pre-2.6 kernels

2009-01-06T21:52:30+00:00

The code began 8 years ago with kernel 2.0 or 2.1, and kernels 2.2 and 2.4 were still supported. These old version need no longer be supported if the code gets merged in mainline. Signed-off-by: Willy Tarreau Cc: Frank Menne Signed-off-by: Greg Kroah-Hartman

Staging: panel: major checkpatch cleanup

2009-01-06T21:52:30+00:00

All of the 401 errors, and 108 of the 235 warnings reported by checkpatch were cleared. The only remanining warnings left concern lines larger than 80 characters. This cleanup will be performed last. Signed-off-by: Willy Tarreau Cc: Frank Menne Signed-off-by: Greg Kroah-Hartman

Staging: add lcd-panel driver

2009-01-06T21:52:29+00:00

This adds the lcd-panel parallel port driver to the staging tree. See the file, drivers/staging/panel/TODO for what needs to be fixed up in order for this to be properly merged into the rest of the kernel tree. Cc: Willy Tarreau Cc: Frank Menne Signed-off-by: Greg Kroah-Hartman
