2011-03-22kstrto*: converting strings to integers done (hopefully) rightAlexey Dobriyan
1. simple_strto*() do not contain overflow checks and crufty, libc way to indicate failure. 2. strict_strto*() also do not have overflow checks but the name and comments pretend they do. 3. Both families have only "long long" and "long" variants, but users want strtou8() 4. Both "simple" and "strict" prefixes are wrong: Simple doesn't exactly say what's so simple, strict should not exist because conversion should be strict by default. The solution is to use "k" prefix and add convertors for more types. Enter kstrtoull() kstrtoll() kstrtoul() kstrtol() kstrtouint() kstrtoint() kstrtou64() kstrtos64() kstrtou32() kstrtos32() kstrtou16() kstrtos16() kstrtou8() kstrtos8() Include runtime testsuite (somewhat incomplete) as well. strict_strto*() become deprecated, stubbed to kstrto*() and eventually will be removed altogether. Use kstrto*() in code today! Note: on some archs _kstrtoul() and _kstrtol() are left in tree, even if they'll be unused at runtime. This is temporarily solution, because I don't want to hardcode list of archs where these functions aren't needed. Current solution with sizeof() and __alignof__ at least always works.

2011-03-22pwm_backlight: add check_fb() hookRobert Morell
In systems with multiple framebuffer devices, one of the devices might be blanked while another is unblanked. In order for the backlight blanking logic to know whether to turn off the backlight for a particular framebuffer's blanking notification, it needs to be able to check if a given framebuffer device corresponds to the backlight. This plumbs the check_fb hook from core backlight through the pwm_backlight helper to allow platform code to plug in a check_fb hook.

2011-03-22mbp_nvidia_bl: remove DMI dependencyMatthew Garrett
This driver only has to deal with two different classes of hardware, but right now it needs new DMI entries for every new machine. It turns out that there's an ACPI device that uniquely identifies Apples with backlights, so this patch reworks the driver into an ACPI one, identifies the hardware by checking the PCI vendor of the root bridge and strips out all the DMI code. It also changes the config text to clarify that it works on devices other than Macbook Pros and GPUs other than nvidia.

2011-03-21matroxfb: remove incorrect Matrox G200eV supportGary Hade
Remove incorrect Matrox G200eV support that was previously added by commit e3a1938805d2e81b27d3d348788644f3bad004f2 A serious issue with the incorrect G200eV support that reproduces on the Matrox G200eV equipped IBM x3650 M2 is the total lack of text (login banner, login prompt, etc) on the console when X is not running and total lack of text on all of the virtual consoles after X is started. Any concerns that the incorrect code (upstream since October 2008) has been successfully used on non-IBM G200eV equipped system(s) appear to be unwarranted. In addition to the serious/non-intermittent nature of issues that have been spotted on IBM systems, complete removal of the incorrect code is clearly supported by the following Matrox (Yannick Heneault) provided input: "It impossible that this patch should have work on a system. The patch only declare the G200eV as a regular G200 which is not case. Many registers are different, including at least the PLL programming sequence. If the G200eV is programmed like a regular G200, it will not display anything." v1 - Initial patch that removed the incorrect code for _all_ G200eV equipped systems. v2 - Darrick Wong provided patch that blacklisted the incorrect code on G200eV equipped IBM systems leaving it enabled on all G200eV equipped non-IBM systems. v3 - Same code changes included with v1 plus additional justification for complete removal of the incorrect code.

2011-03-16fbdev: sh_mobile_lcdc: Add YUV framebuffer supportDamian Hobson-Garcia
Supports YCbCr420sp, YCbCr422sp, and YCbCr44sp, formats (bpp = 12, 16, and 24) respectively. When double-buffering both Y planes appear before the C planes (Y-Y-C-C), as opposed to Y-C-Y-C. Set .nonstd in struct sh_mobile_lcdc_chan_cfg to enable YUV mode, and use .bpp to distiguish between the 3 modes. The value of .nonstd is copied to bits 16-31 of LDDFR in the LCDC and should be set accordingly. .nonstd must be set to 0 for RGB mode. Due to the encoding of YUV data, the framebuffer will clear to green instead of black. In YUV 420 mode, panning is only possible in 2 line increments. Additionally in YUV 420 mode the vertical resolution of the framebuffer must be an even number.
