2011-06-01TILER: Use owner's pid to notify devhSubin K G
This is with respect to the change made at the deh layer. In earlier implementation devh will always take the current pid and use that to send the death notification.This was causing some issue because some times the process which acquired the handle may not the one releasing the handle,and in that case,will be sending the wrong pid.In order to take care of this issue always use the stored pid in driver's private data to send the notification.

New assemblers need -march=armv7-a+sec on command line or .arch_extension sec inline to enable use of the smc instruction. This patch uses as-instr to check the latter to conditionally enable the former in AFLAGS for files that use smc. Checked on both old and new binutils to verify that it does not break old versions.

2011-05-19smsc95xx: generate random MAC address once, not every ifupBernard Blackham
The smsc95xx driver currently generates a new random MAC address every time the interface is brought up. This makes it impossible to override using the standard `ifconfig hw ether` approach. Past patches tried to make the MAC address a module parameter or base it off the die ID, but it seems to me much simpler (and hopefully less controversial) to stick with the current random generation scheme, but allow the user to change the address. This patch does exactly that - it moves the random address generation from smsc95xx_reset() into smsc95xx_bind(), so that it is done once on module load, not on every ifup. The user can then override this using the standard mechanisms. Applies against 2.6.35 and linux-2.6 head. Signed-off-by: Bernard Blackham <b-omap@largestprime.net> Signed-off-by: David S.

2011-05-18arm: omap4: pandaboard: turn on PHY reference clock at initAnand Gadiyar
The SMSC 3320 USB PHY on the OMAP4 Pandaboard needs a 19.2 MHz reference clock. This clock is provided from the OMAP4's fref_clk3 pad. Recent changes to clock44xx_data.c made the clock framework aware of the existence of these fref_clk[i] lines. If the option CONFIG_OMAP_RESET_CLOCKS is enabled in the kernel, then the clock framework will turn these clocks off during bootup. Explicitly request and keep this clock enabled at init for the Pandaboard, so that the PHY receives this clock at all times.

2011-05-05pvr: restrict visibility of DC devices to corresponding drm_device instanceRob Clark
Associate a handle to display-class devices, so visibility can be restricted to certain drm_device instances. So now, you can build kernel with two drm_device instances, and two corresponding framebuffer instances. And when userspace enumerates the DC devices it will see only the one corresponding to the drm_device that it has opened. So now you can either build the kernel with one drm_device, with the fb possibly spanning multiple independent displays, but acting as a single virtual display. Or with multiple drm_devices acting as multiple independent displays. In either case, when userspace enumerates the display-class devices, they see only a single device corresponding to the single fbdev associated with that drm_device.

2011-05-05omap_gpu drm display driverRob Clark
A DSS based DRM display driver, which provides a plugin interface for 3d/2d accelerators to register. The core driver handles construction of CRTC/encoder/connectors to represent the hardware, and support KMS. This driver replaces omapfb.. omap_gpu drm driver allocates framebuffer memory and implements (with the help of drm_fb_helper) the legacy fbdev interface. The driver maps CRTCs to overlays, encoders to overlay-managers, and connectors to dssdev's. To set vram on the command-line (bootargs): omapgpu.vram=0:32M (same syntax as omapfb but use omapgpu module name instead) To set default resolution on command-line, use the normal video= line, such as: video=HDMI Type A-1:800x600@60 note: sometimes there is an issue with the hdmi driver overriding the set resolution when it gets a hotplug event and reads the EDID. The hdmi driver will need to be tamed so that it does not override the currently set timings, at least not as long as they are still a valid choice according to the EDID. And of course, to enable debug: drm.debug=7 The omap_gpu drm driver supports using platform_data to configure which omap_gpu devices are assigned which overlays/managers/devices. If multiple devices are registered, each one creates it's own framebuffer and fbdev. This allows for multiple independent display contexts (like with the old omapfb driver) in cases where you don't want to share one virtual framebuffer across multiple displays.

2011-05-05omap:dss:hdmi: tame hdmi driverRob Clark
Main change is to avoid automatically picking timings. Now the driver defaults to a safe 640x480, and leaves it to the upper layer (drm driver) to pick the desired resolution based on what the user selects and the drm infrastucture's parsing of the EDID. Note: some of this may need to be checked w/ S3D team, and other use cases where android is using the HDMI display.. it is still the correct approach for the HDMI driver to not automatically pick timings, but possibly there needs to be something in userspace to do this if x11 is not running. See the modetest test app coming from libdrm tree.. something like this could be used to set the modeline from userspace.
2011-05-05omap:dss: add is_detected() driver APIRob Clark
