* lxfb: Maintain video processor palette through suspend/resumeDaniel Drake2010-12-011-1/+3
| | | | | | | | | | | | | | | | The Geode X driver uses both of the LX's palettes, one for gamma correction and one for colormaps. The kernel driver currently only backs up the one used for colormaps during suspend/resume. If you mess with gamma settings and do a suspend/resume, colors go funny. Fix this by backing up the video proc palette during suspend/resume, alongside the display controller one which is already handled.

* lxfb: set the H- and V-SYNC polarity of the flatpanel outputMichael Grzeschik2010-03-251-0/+2
| | | | | | | | | | | Fixup for the flatpanel output. The geode_modedb attribute flags are used to set the SYNC polarity of the flatpanel. Without this patch our flatpanel registers stayed unconfigured, so we just saw garbage output.

* lxfb: drop dead declarations from headerAndres Salomon2008-07-241-2/+0Star
| | | | | | | | | | We never sent the gamma stuff upstream, and don't really care about it. However, lx_[gs]_et_gamma prototypes snuck into lxfb.h anyways; there are no definitions for them. Drop the dead code. Signed-off-by: Andres Salomon <dilinger@debian.org> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
* lxfb: add power management functionalityAndres Salomon2008-04-281-0/+45
| | | | | | | | | | | | | | | | | | This adds the ability to suspend/resume the lxfb driver, which includes: - Register and palette saving code; registers are stored in lxfb_par. A few MSR values are saved as well. - lx_powerup and lx_powerdown functions which restore/save registers and enable/disable graphic engines. - lxfb_suspend/lxfb_resume Originally based on a patch by Jordan Crouse.

* lxfb: rearrange/rename MSR bitfieldsAndres Salomon2008-04-281-25/+27
| | | | | | | | | | | Finally, move the MSR bitfields around in lxfb.h, and rename them. Alas, most of that crap appears to be undocumented.

| | | | | | | | | | | Finally drop the last remnants of df_regs, using vp_regs instead. Also, drop panel_width and panel_height from lxfb_par; they're unused.

* lxfb: clean up register definitionsAndres Salomon2008-04-281-108/+269
| | | | | | | | | | | | | | | | | - Rename various bitfield defines to match the data sheet names. - Rename DF_ register definitions to VP_ to match the data sheet; ie, DF_PAR -> VP_PAR. - for GP/DC registers, rather than defining to specific addresses, use an enum to number them sequentially and just multiply by 4 (bytes) to access them (in read_*/write_* functions). - for VP/FP registers, use an enum and multiple by 8 (bytes). They're 64bit registers. Signed-off-by: Andres Salomon <dilinger@debian.org> Cc: "Antonino A.

* lxfb: create GP/DC/VP/FP-specific handlers rather than using readl/writelAndres Salomon2008-04-281-0/+43
| | | | | | | | | | | | This creates read_gp/write_gp, read_dc/write_dc, read_vp/write_vp, and read_fp/write_fp for reading and updating those registers. Note that we don't follow the 'DF' naming; those will be renamed to VP shortly. Signed-off-by: Andres Salomon <dilinger@debian.org> Cc: "Antonino A.

* x86: geode: MSR cleanupAndres Salomon2008-04-281-8/+0Star
| | | | | | | | | | | | | | | | | This cleans up a few MSR-using drivers in the following manner: - Ensures MSRs are all defined in asm/geode.h, rather than in misc places - Makes the naming consistent; cs553[56] ones begin with MSR_, GX-specific ones start with MSR_GX_, and LX-specific ones start with MSR_LX_. Also, make the names match the data sheet. - Use MSR names rather than numbers in source code - Document the fact that the LX's MSR_PADSEL has the wrong value in the data sheet. That's, uh, good to note.

* LXFB: use the correct MSR number for panel supportJordan Crouse2007-11-151-1/+1
| | | | | | | | | | | | A relatively recent version of the Geode LX datasheet listed the wrong address for one of the MSRs that controls TFT panels, resulting in breakage.
