2010-05-18OMAP3630: DSS2: Updating MAX divider valueKishore Y1-5/+19
In DPLL4 M3, M4, M5 and M6 field width has been increased by 1 bit in 3630. So the max divider value that can be achived will be 32 and not 16. In 3630 the functional clock is x1 of DPLL4 and not x2. Hence multiplier 2 is removed.

2010-05-18OMAP: DSS2: Make partial update width evenTomi Valkeinen1-0/+20
There are some strange problems with DSI and updates with odd widths. One particular problem is that HS TX timeout triggers easily with updates with odd widths. This patch makes the updates widths even, circumventing the problem. There should be no ill side effects with increasing the update area slightly to make the width even.

2010-05-18fbmem, drm/nouveau: kick firmware framebuffers as soon as possibleMarcin Slusarz1-18/+25
Currently vesafb/efifb/... is kicked when hardware driver is registering framebuffer. To do it hardware must be fully functional, so there's a short window between start of initialisation and framebuffer registration when two drivers touch the hardware. Unfortunately sometimes it breaks nouveau initialisation. Fix it by kicking firmware driver(s) before we start touching the hardware.

2010-05-07viafb: make procfs entries optionalFlorian Tobias Schandinat2-0/+22
viafb: make procfs entries optional This patch adds a config option to enable procfs entries for direct hardware access. This was the old behaviour but the option defaults to no as this is really ugly and should not be needed if the driver works correct (and if it doesn't, it needs to be fixed). That stuff is really something that should - not be needed at all (the driver should be capable of doing it) - not be there (debugfs would be better for such things) So add this option just for backwards compatiblity.

2010-05-07viafb: fix proc entry removalFlorian Tobias Schandinat1-6/+7
viafb: fix proc entry removal Trying to remove unregistered proc entries became painful and is useless anyway. So remove the removal of an entry that was never registered and duplicate the logic for one which is added conditionally. Additionally move the removal above releasing fb_info as we still need the information. This prevents tainting the kernel by the procfs warn on and avoiding access to already freed memory is probably also a good idea. Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

2010-05-07viafb: Reserve framebuffer memory for the upcoming camera driverJonathan Corbet2-0/+26
The camera engine captures to framebuffer memory, so we need to set some aside for that purpose. There is no proper memory allocator for fbmem; instead, accel.c just trims some space off the top. Alas, without creating that proper memory allocator, the only way to make this work is to hack it into the same bit of code in accel.c. The allocation must happen *after* the others (some code, including user-space XV stuff, makes assumptions on where the cursor space is), and before the rest of the framebuffer is set up.

2010-05-07viafb: package often used basic io functionsFlorian Tobias Schandinat3-25/+63
This patch puts redesigned versions of the basic io functions that are used overall the driver in an extra header. It is prefixed with via_ as no framebuffer dependend stuff is in there. They were inlined as they are really simple which reduced the module size about 2.5%. The parameter order of read and write was fixed as it really doesn't make sense to change the order as they are parts of the same address and not source and destination. Wrapper which use the new functions were added to hw.h to replicate the old interface and avoid changing all old code.
