This patch adds s3c_fb_driverdata s3c_fb_data_exynos5 for EXYNOS5 and adds extended timing control setting. EXYNOS5 FIMD needs extended setting for video timing control. Additional bits are added to VIDTCON2, VIDWxxADD2, VIDOSDxA and VIDOSDxB registers in order to set timing value for lager resolution. Also, address offset of VIDTCONx registers is changed from 0x0 to 0x20000, thus variable type should be changed to int type to handle the address offset of VIDTCONx registers for EXYNOS5 FIMD.

2012-03-04udlfb: Add module_param to allow forcing pixel_limitBen Collins1-0/+12
Some user scenarios need to prioritize performance over maxiumum resolution. Also, some devices may have bad vendor descriptors, and this allows the user to set a pixel limit that matches their specific device to avoid blank screens on higher resolution monitors. 700000 minimum for DL-115, 2360000 maximum for DL-195 Signed-off-by: Ben Collins <bcollins@ubuntu.com> Signed-off-by: Bernie Thompson <bernie@plugable.com>
2012-03-04udlfb: Make sure to get correct endian keys from vendor descriptorBen Collins1-1/+1
The driver was not using le16_to_cpu when reading keys from the vendor descriptor, causing incorrect parsing. Mainly, sku_pixel_limit was not being parsed on big-endian systems. This would result in a blank screen on big-endian CPUs where the DL chips's max mode was smaller than the monitor's native mode.

2012-03-01OMAPDSS: APPLY: make ovl_enable/disable synchronousTomi Valkeinen1-0/+6
ovl->enable/disable are meant to be synchronous so that they can handle the configuration of fifo sizes. The current kernel doesn't configure fifo sizes yet, and so the code doesn't need to block to function (from omapdss driver's perspective). However, for the users of omapdss a non-blocking ovl->disable is confusing, because they don't know when the memory area is not used any more. Furthermore, when the fifo size configuration is added in the next merge window, the change from non-blocking to blocking could cause side effects to the users of omapdss. So by making the functions block already will keep them behaving in the same manner. And, while not the main purpose of this patch, this will also remove the compile warning: drivers/video/omap2/dss/apply.c:350: warning: 'wait_pending_extra_info_updates' defined but not used Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

2012-02-23OMAPDSS: HACK: Ensure DSS clock domain gets out of idle when HDMI is enabledArchit Taneja1-1/+23
For DSS clock domain to transition from idle to active state. It's necessary to enable the optional clock DSS_FCLK before we enable the module using the MODULEMODE bits in the clock domain's CM_DSS_DSS_CLKCTRL register. This sequence was not followed correctly for the 'dss_hdmi' hwmod and it led to DSS clock domain not getting out of idle when pm_runtime_get_sync() was called for hdmi's platform device. Since the clock domain failed to change it's state to active, the hwmod code disables any clocks it had enabled before for this hwmod. This led to the clock 'dss_48mhz_clk' gettind disabled. When hdmi's runtime_resume() op is called, the call to dss_runtime_get() correctly enables the DSS clock domain this time. However, the clock 'dss_48mhz_clk' is needed for HDMI's PHY to function correctly. Since it was disabled previously, the driver fails when it tries to enable HDMI's PHY. Fix this for now by ensuring that dss_runtime_get() is called before we call pm_runtime_get_sync() for hdmi's platform device. A correct fix for later would be to modify the DSS related hwmod's mainclks, and also some changes in how opt clocks are handled in the DSS driver. This fixes the issue of HDMI not working when it's the default display. The issue is not seen if any other display is already enabled as the first display would have correctly enabled the DSS clockdomain.

2012-02-09ARM: omap: fix oops in drivers/video/omap2/dss/dpi.cRussell King1-0/+5
When a PMIC is not found, this driver is unable to obtain its 'vdds_dsi_reg' regulator. Even through its initialization function fails, other code still calls its enable function, which fails to check whether it has this regulator before asking for it to be enabled. This fixes the oops, however a better fix would be to sort out the upper layers to prevent them calling into a module which failed to initialize.

2012-01-29drivers/video/au*fb.c: use devm_ functionsJulia Lawall2-28/+13
The various devm_ functions allocate memory that is released when a driver detaches. This patch uses these functions for data that is allocated in the probe function of a platform device and is only freed in the remove function. In au1100fb.c, the probe function now returns -ENODEV on failure.

2012-01-28udlfb: remove sysfs framebuffer device with USB .disconnect()Kay Sievers2-2/+18
The USB graphics card driver delays the unregistering of the framebuffer device to a workqueue, which breaks the userspace visible remove uevent sequence. Recent userspace tools started to support USB graphics card hotplug out-of-the-box and rely on proper events sent by the kernel. The framebuffer device is a direct child of the USB interface which is removed immediately after the USB .disconnect() callback. But the fb device in /sys stays around until its final cleanup, at a time where all the parent devices have been removed already. To work around that, we remove the sysfs fb device directly in the USB .disconnect() callback and leave only the cleanup of the internal fb data to the delayed work. Before: add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb0 (graphics) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) remove /2-1.2:1.0/graphics/fb0 (graphics) After: add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) add /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0/graphics/fb1 (graphics) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2/2-1.2:1.0 (usb) remove /devices/pci0000:00/0000:00:1d.0/usb2/2-1/2-1.2 (usb) Cc: stable@vger.kernel.org Tested-by: Bernie Thompson <bernie@plugable.com> Acked-by: Bernie Thompson <bernie@plugable.com> Signed-off-by: Kay Sievers <kay.sievers@vrfy.org> Signed-off-by: Florian Tobias Schandinat <FlorianSchandinat@gmx.de>

2012-01-28video: da8xx-fb: reset LCDC only if functional clock changes with DVFSManjunathappa, Prakash1-5/+11
LCDC functional clock may or may not be derived from CPU/MPU DPLL, For example, AM335x => Separate independent DPLL for LCDC Davinci => Same DPLL as MPU So, on platforms where LCDC functional clock is not derived from CPU/MPU PLL it is not required to reset LCDC module as its functional clock does not change with DVFS. This patch adds check to do reset only if functional clock changes between pre and post notifier callbacks with DVFS.
