2012-04-09video: s3c-fb: remove 'default_win' element from platform dataThomas Abraham
The decision to enable or disable the data output to the lcd panel from the controller need not be based on the value of 'default_win' element in the platform data. Instead, the data output to the panel is enabled if any of the windows are active, else data output is disabled.

2012-04-09video: s3c-fb: move video interface timing out of window setup dataThomas Abraham
The video interface timing is independent of the window setup data. 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. This also removes the restriction that atleast one window should have the same resolution as that of the panel attached.

2012-03-06video: s3c-fb: Add support EXYNOS5 FIMDJingoo Han
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.

2012-01-03video: s3c-fb: Take a runtime PM reference when unblankedMark Brown
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.

2012-01-03video: s3c-fb: Use s3c_fb_enable() to enable the framebufferMark Brown
The s3c-fb driver has a function called s3c_fb_enable() which turns on and off the physical output. However it is only actually used in paths which disable the screen, the enabling just writes to the register. Make the code less confusing by ensuring that the enable also goes through the same path.

2012-01-03video: s3c-fb: Make runtime PM functional againMark Brown
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.

2011-12-19video: s3c-fb: modify runtime pm functionsJingoo Han
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.

2011-08-24video: s3c-fb: Add support EXYNOS4 FIMDJingoo Han
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.

This patch fixes mishandling in virtual resolution checking.

However, it is meaningless, since virtual_x and virtual_y are fixed and user cannot change virtual resolution. Therefore, virtual resolution should be more than resolution such as xres and yres.

2011-05-24video: s3c-fb: correct transparency checking in 32bppJingoo Han
32bpp means ARGB 8888 in the driver, therfore the transparency length and offset should be 8 and 24 respectively. However, the transparency length and offset were previously 0, which means that the driver supports RGB 888 without alpha blending when 32bpp is used. So, the transparency checking in 32bpp is corrected so that the transparency length and offset are 8 and 24 respectively.
