* video/s3c: move platform_data out of arch/armArnd Bergmann2013-04-111-2/+1
| | | | | | | | | | | | The s3c-fb driver requires header files from the samsung platforms to find its platform_data definition, but this no longer works on multiplatform kernels, so let's move the data into a new header file under include/linux/platform_data.

* Drivers: video: remove __dev* attributes.Greg Kroah-Hartman2013-01-031-8/+7
| | | | | | | | | | | | | | CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

* video: s3c-fb: fix red offset and length for ARGB232 formatJingoo Han2012-11-261-2/+2

The resolution of the window can be smaller than that of the lcd panel to which the video data is output. So move the video timing data from the per-window setup data to the platform specific section in the platform data.

| | | | | | | | | | | | | | | | | | When the framebuffer is unblanked hold a runtime PM reference. This prevents us powering down when userspace has left an image on the framebuffer and prepares the way for being able to power down the hardware when an application still has the device open. Since we now hold a runtime PM reference whenever the display is unblanked there is no need for the runtime power management to disable and enable the display, and doing so would lead to runtime PM trying to recurse into itself when called from the blanking code, so split the runtime PM into separate functions which only deal with the clocks. The PM core will runtime resume the device prior to system suspend.

* video: s3c-fb: Make runtime PM functional againMark Brown2012-01-031-20/+31
| | | | | | | | | | | | | | | | | | | | | | | | The change in "video: s3c-fb: modify runtime pm functions" (commit 35784b) renders the runtime power management for the device completely ineffectual as while it leaves runtime power management notionally enabled a runtime power reference is held for the entire time the device is registered meaning it will never actually do anything. A further issue is introduced as runtime power management is added during the system suspend path which is not something which drivers are supposed to do and would interact poorly if there were any operations done in the runtime power management callbacks. While this does make things simpler (the main motivation for the original change) it will not only cause us to use more power in the framebuffer controller but will also prevent us entering lower power domain and SoC wide states as we can never power down the domain containing the device. Since neither of these things is desirable revert the change.

| | | | | | | | | | | | | | | | | | | | | | | | Runtime suspend and runtime resume are modified in order to reduce the complexity and improve the usability of runtime pm. After probe function, s3c-fb driver is not suspended until suspend or remove is called. The scheme is changed as follows: runtime_get is only called in probe and resume. runtime_put is only called in remove and suspend. open/close cannot call the runtime_get/put. Also, runtime_susepnd/resume are just called by runtime pm, not doing suspend/resume routine any longer. This is because open/close cannot call the runtime_get/put; the suspend/resume routine in runtime_suspend/resume were previously used when open and close were called. The name of s3c-fb dev_pm_ops is changed from s3cfb_pm_ops to s3c_fb_pm_ops in order to use more consistent naming.

| | | | | | | | | | | | | | | | | | | This patch adds struct s3c_fb_driverdata s3c_fb_data_exynos4 for EXYNOS4 and adds lcd clock gating support. FIMD driver needs two clocks for FIMD IP and LCD pixel clock. Previously, both clocks are provided by using bus clock such as HCLK. However, EXYNOS4 can not select HCLK for LCD pixel clock because the EXYNOS4 FIMD IP does not have the CLKSEL bit of VIDCON0. So, FIMD driver should provide the lcd clock using SCLK_FIMD as LCD pixel clock for EXYNOS4. The driver selects enabling lcd clock according to has_clksel which means the CLKSEL bit of VIDCON0. If there is has_clksel, the driver will not enable the lcd clock using SCLK_FIMD because bus clock using HCLK is used a LCD pixel clock.
