* sm501fb: Ensure panel interface is not tristated when setupBen Dooks2007-10-16
| | | | | | | | | | | | When we setup the panel interface whilst configuring the framebuffer, we should ensure the panel interface is not in tristate, in case the bootloader or previous setup has not enabled it.

* sm501fb: update suspend and resume codeBen Dooks2007-10-16
| | | | | | | | | | | | | | | The suspend and resume code is failing to restore the CRT control register, thus causing the CRT data-path to get changed if the SM501 experiences a reset over suspend. Also move some of the debug messages to dev_dbg() level and ensure that the suspend code does not try and restore anything it did not manage to save.

* [PATCH] fb: sm501fb off-by-1 sysfs storePaul Mundt2007-03-05
| | | | | | | | | | | | | | | | | | | | | | | 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.

* [PATCH] fb: SM501 framebuffer driverBen Dooks2007-02-20
Driver for the Silicon Motion SM501 multifunction device framebuffer subsystem. This driver supports both the CRT and LCD panel heads, with some simple acceleration for the cursor plotting and support for screen panning. There is no current support for bitblt/drawing engines, which should be added at a later date. This has been tested on a number of configurations, including PCI and generic-bus, on PPC, ARM and SH4 [akpm@linux-foundation.org: fix warnings] Signed-off-by: Ben Dooks <ben-linux@fluff.org> Signed-off-by: Vincent Sanders <vince@arm.linux.org.u.> Acked-by: James Simmons <jsimmons@infradead.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
