Some pieces of userspace like debian-installer expect to find the fb0 driver name by readlink-ing /sys/class/graphics/fb0/device/driver but this was broken with amba-clcd as it sets up fb_info manually and missed the .device parent pointer.

The Freescale DIU framebuffer driver defines two constants, MIN_PIX_CLK and MAX_PIX_CLK, that are supposed to represent the lower and upper limits of the pixel clock. These values, however, are true only for one platform clock rate (533MHz) and only for the MPC8610. So the actual range for the pixel clock is chip-specific, which means the current values are almost always wrong. The chance of an out-of-range pixel clock being used are also remote. Rather than try to detect an out-of-range clock in the DIU driver, we depend on the board-specific pixel clock function (e.g. p1022ds_set_pixel_clock) to clamp the pixel clock to a supported value.

The situation in which the problem occurred was with a Plugable UGA-2K-A connected to a Samsung EX2220X display. The driver indicates that 1920x1080 is a valid mode (the first mode available, in fact), but proceeds to set the framebuffer size to 1600x1200. The patch corrects what seems to be a logic error, regarding unsetting the FB_MISC_1ST_DETAIL flag, if the first (top/best) mode is invalid. The existing code unset the flag if ANY mode was invalid.

A recent modification to the runtime PM code on mach-shmobile made a wrong RTPM implementation in the sh_mobile_hdmi driver apparent, which broke HDMI hotplug detection support on ap4evb. This patch does not implement a proper dynamic RTPM support for sh_mobile_hdmi, instead it restores the previous working state by statically enabling it. A more power-efficient solution should be implemented for the next kernel version. Signed-off-by: NGuennadi Liakhovetski <g.liakhovetski@gmx.de> Signed-off-by: NPaul Mundt <lethal@linux-sh.org>

This patch fixes mishandling in virtual resolution checking. Previously, virtual resolution is changed to virtual_x and virtual_y which mean the size for buffer allocation, when s3c_fb_check_var is called by fb_check_var. 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.

Running fbcon on an uncached framebuffer is remarkably slow. So try to enable write combining in efifb. Without this patch, it takes 5.8 seconds from efifb probe to i915 probe (default options; no plymouth or quiet mode). With this patch, it only takes 1.7 seconds. That means we wasted over 4 seconds just writing to UC memory.

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.
