* video: convert drivers/video/* to use module_platform_driver()Axel Lin2011-12-031-12/+1
| | | | | | | | | | | | | | | | | This patch converts the drivers in drivers/video/* to use the module_platform_driver() macro which makes the code smaller and a bit simpler.

* console: rename acquire/release_console_sem() to console_lock/unlock()Torben Hohn2011-01-261-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | | The -rt patches change the console_semaphore to console_mutex. As a result, a quite large chunk of the patches changes all acquire/release_console_sem() to acquire/release_console_mutex() This commit makes things use more neutral function names which dont make implications about the underlying lock. The only real change is the return value of console_trylock which is inverted from try_acquire_console_sem() This patch also paves the way to switching console_sem from a semaphore to a mutex.

Unfortunately in the case of sm501fb these happen quite early in the initialization code, well before the mutex_init() that takes place in register_framebuffer(), leading to: Badness at kernel/mutex.c:207 Pid : 1, Comm: swapper CPU : 0 Not tainted (2.6.31-rc1-00284-g529ba0d-dirty #2273) PC is at __mutex_lock_slowpath+0x72/0x1bc PR is at __mutex_lock_slowpath+0x66/0x1bc ... matroxfb appears to have the same issue and has solved it with an early mutex_init(), so we do the same for sm501fb.

* fbdev: add mutex for fb_mmap lockingKrzysztof Helt2009-06-301-8/+13
| | | | | | | | | | | | | | | | | | | | | Add a mutex to avoid a circular locking problem between the mm layer semaphore and fbdev ioctl mutex through the fb_mmap() call. Also, add mutex to all places where smem_start and smem_len fields change so the mutex inside the fb_mmap() is actually used. Changing of these fields before calling the framebuffer_register() are not mutexed. This is 2.6.31 material. It removes one lockdep (fb_mmap() and register_framebuffer()) but there is still another one (fb_release() and register_framebuffer()). It also cleans up handling of the smem_start and smem_len fields used by mutexed section of the fb_mmap().

* sm501fb: clear framebuffer memory and paletteMagnus Damm2008-02-061-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | Avoid displaying garbage on unused framebuffers. For most users a single framebuffer is used together with fbcon. sm501fb supports two framebuffers where one often is assigned to fbcon and the other one is left unused during the boot. The problem here is that framebuffers not in use by fbcon happen to display garbage. This can easily be solved by making sure that framebuffer memory and palette ram are cleared. The problem can be observed by using looking at the panel output (fb1) after booting the kernel with fbcon on crt (fb0). This is the default configuration. It's also possible to watch the garbage on the crt framebuffer by passing "fbcon=map:1" on the kernel cmdline. This will assign fbcon to the panel (fb1) and leave the crt (fb0) unused.

* sm501fb: control panel pin usage with platform data flagsMagnus Damm2008-02-061-16/+25
| | | | | | | | | | | | | | | | | | | | | This patch makes it possible to control panel pins usage with flags passed from the platform data. Without this patch the sm501fb driver always controls the VBIASEN and FPEN pins. The polarity and use of these pins are very platform specific, so this patch introduces the flags SM501FB_FLAG_PANEL_USE_VBIASEN and SM501FB_FLAG_PANEL_USE_FPEN which enable the use of these pins. This patch is needed to support the a Sharp LQ104V1DG21 lcd panel on SuperH platforms such as R2D-1 and R2D-PLUS boards. Letting the sm501fb driver control the FPEN and VBIASEN pins like today just results in lcd panel flicker. Signed-off-by: Magnus Damm <damm@igel.co.jp> Cc: "Antonino A.

* [PATCH] fb: sm501fb off-by-1 sysfs storePaul Mundt2007-03-051-3/+3
| | | | | | | | | | | | | | | | | | | | | | | Currently sm501fb_crtsrc_store() won't allow the routing to be changed via echos from userspace in to the sysfs file. The reason for this is that the strnicmp() for both heads uses a sizeof() for the string length, which ends up being strlen() + 1 (\0 in the normal case, but the echo gives a newline, which is where the issue occurs), this then causes a mismatch and subsequently bails with the -EINVAL. In addition to this, the hardcoded lengths were then used for the store length that was returned, which ended up being erroneous and resulting in a write error. There's also no point in returning anything but the full length since it will -EINVAL out on a mismatch well before then anyways. sizeof("string") is great for making sure you have space in your buffer, but rather less so for string comparisons :-) Signed-off-by: Paul Mundt <lethal@linux-sh.org> Acked-by: Ben Dooks <ben-linux@fluff.org> Cc: "Antonino A.
