A memory clock value (MCLK) is changed to a minimum required by a current mode bandwidth. This usually lowers the MCLK to its minimum (50 MHz) thus decreasing the card performance. Just leave the MCLK value set by card BIOS. The CL-GD5446 Technical Reference Manual point 9.9.1.3 states that if a pixclock value is close (~1%) to the MCLK or MCLK/2 this may result in a jitter on the screen. A countermeasure is to use the MCLK as pixclock source instead of a VCLK. The patch implements this as well. Signed-off-by:

The 16bpp mode did not work on the Cirrus cards as the visual type was set to DIRECTCOLOR instead of TRUECOLOR. The Alpine family used one incorrect register setting so this 16bpp modes generated wrong horizontal frequency. Signed-off-by:

Add support for Intel's 945GME graphics chip to the intelfb driver. I have assumed that the 945GME is identical to the already-supported 945GM apart from its PCI IDs; this is based on a quick look at the X driver for these chips which seems to treat them identically. The 945GME is used in the ASUS Eee 901, and I coded this in the hope that I'd be able to use it to get a console at the native 1024x600 resolution which is not known to the BIOS. I realised too late that the intelfb driver does not support mode changing on laptops, so it won't be any use for me. Signed-off-by:

Add a new internal mechanism to gpiolib to support low power operations by letting gpio_chip instances see when their GPIOs are in use. When no GPIOs are active, chips may be able to enter lower powered runtime states by disabling clocks and/or power domains. Signed-off-by:

This updates most of the OMAP drivers which are in mainline to switch to using the cross-platform GPIO calls instead of the older OMAP-specific ones. This is all fairly brainless/obvious stuff. Probably the most interesting bit is to observe that the omap-keypad code seems to now have a portable core that could work with non-OMAP matrix keypads. (That would improve with hardware IRQ debouncing enabled, of course...) Signed-off-by:

Add a new gpiolib mechanism: gpio_chip instances can provide mappings between their (input) GPIOs and any associated IRQs. This makes it easier for platforms to support IRQs that are provided by board-specific external chips instead of as part of their core (such as SOC-integrated GPIOs). Also update the irq_to_gpio() description, saying to avoid it because it's not always supported. Signed-off-by:

Make the I2C external GPIO expander drivers register themselves at subsys_initcall() time when they're statically linked. SOC-integrated GPIOs are available starting very early -- early in arch_initcall() at latest, but often even before initcalls start to run -- so this improves consistency, so more subsystems can rely on GPIOs in their own subsys_initcall() code. (This isn't a theoretical problem. This is one of several patches needed to resolve oopsing observed when statically linking kernels on a DaVinci EVM. Its pcf857x GPIOs needed to be available well before some other drivers initialized.) Signed-off-by:

According to the documentation gpio_free should only be called from task context only. To make this more explicit add a might sleep to all implementations. This is the generic part which changes gpiolib and the fallback implementation only. Signed-off-by:
