On the sam9 EK boards, the LCD backlight is hooked up to a PWM output from the LCD controller. It's controlled by "contrast" registers though. This patch lets boards declare that they have that kind of backlight control. The driver can then export this control, letting screenblank and other operations actually take effect ... reducing the typically substantial power drain from the backlight. Note that it's not fully cooked - doesn't force backlight off during system suspend - the "power" and "blank" events may not be done right This should be easily added in the future.

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. Signed-off-by:

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:

The current nvidiafb_check_var() simply bails out if the selected mode is out of range of the panel dimensions. A good question would be why the bogus mode is being selected in the first place -- the panel dimensions that are read back are certainly bogus, but alas, I have no idea where to even begin looking at the i2c/EDID/DDC mess: nvidiafb: Device ID: 10de0165 nvidiafb: CRTC0 analog not found nvidiafb: CRTC1 analog not found nvidiafb: EDID found from BUS1 nvidiafb: CRTC 0 is currently programmed for DFP nvidiafb: Using DFP on CRTC 0 nvidiafb: Panel size is 1280 x 1024 nvidiafb: Panel is TMDS nvidiafb: unable to setup MTRR nvidiafb: Flat panel dithering disabled nvidiafb: PCI nVidia NV16 framebuffer (64MB @ 0xC0000000) In my .config I presently have: CONFIG_FIRMWARE_EDID=y CONFIG_FB_DDC=y CONFIG_FB_NVIDIA_I2C=y I've not tried fiddling with these options, as I haven't the vaguest idea what I should be looking at. As a workaround, simply groveling for a new mode based on the probed dimensions seems to work ok. While it would be nice to debug this further and sort out why the panel information is bogus, I think it's still worth retrying the mode based on the panel information at hand as a last-ditch effort, rather than simply bailing out completely.

This third part of an extension to support more pca953x chips updates the logic to handle the smaller register widths used by the 4-bit and 8-bit parts, and to use the chip type to determine how many GPIOs it provides. As long as we don't support interrupt and reset capabilities, those size issues are the only software-visible differences between these parts. Signed-off-by:

AT91sam9 RTC support, primarily in the form of an RTT-as-RTC driver that was extracted from 2.6.23-at91 patch and updated: - Relies on now-merged platform updates, which associate the RTT hardware address with each RTT and use the "at91_rtt" name. - RTC framework related fixes and cleanups, notably: * removed now-needless suspend/resume clock offset logic * alarm read/write now respects the "enabled" flag * suspend always disables update irqs * shutdown (and startup) disables all irqs - Misc cleanup: * use dev_*() messaging * add comments * remove globals, * ... etc - Don't force use of RTT0 and GPBR0. Either resource may need to be used for other purposes (like NO_HZ support). - Update "AT91RM9200 RTC" Kconfig to allow it on SAM9RL chips (it has both RTT and RTC). Driver binding uses bus_find_device() to avoid needing any kind of "timer library" code when there's more than one RTT module. (This timer can be used as an RTC, to support NO_HZ operation, or potentially for other stuff. The choice is a per-system policy.) Signed-off-by: -

Remove some more references to dev->power.power_state. That field is overdue for removal, but we can't do that while it's still referenced in the kernel. The only reason to update it was to make the /sys/devices/.../power/state files (now removed) work better. Signed-off-by:
