When we setup up the VMA flags for the mmap flag and we end up using the
fallback mmap functionality we set the vma->vm_flags |= VM_IO. However we
neglect to propagate the flag to the vma->vm_page_prot.This bug was found when Linux kernel was running under Xen. In that
scenario, any page that has VM_IO flag to it, means that it MUST be a
MMIO/VRAM backend memory , _not_ System RAM. That is what the fbmem.c
does: sets VM_IO, ioremaps the region - everything is peachy.Well, not exactly. The vm_page_prot does not get the relevant PTE flags
set (_PAGE_IOMAP) which under Xen is a death-kneel to pages that are
referencing real physical devices but don't have that flag set.This patch fixes this.

Add a simple algorithm which calculates the pixel clock based on the video
mode parameters. This is only done when no pixel clock is supplied
through the platform data.This allows drivers to omit the pixel clock data and thus share the

Supports all bpp modes.
The PRTCON register is used to disable in-hardware updates of registers
that store start and end addresses of framebuffer memory. This prevents
display corruption in case we do not make it before VSYNC with updating
them atomically. With this feature there is no need to wait for a VSYNC
interrupt before each such update.Signed-off-by: Pawel Osciak

The following problems were found in the above situation:
sfb->windows[win] was being assigned at the end of s3c_fb_probe_win only.
This resulted in passing a NULL to s3c_fb_release_win if probe_win
returned early and a memory leak.dma_free_writecombine does not allow its third argument to be NULL.
fb_dealloc_cmap does not verify whether its argument is not NULL.

It has been working fine at 16bpp but in case of pixel format more then
24bpp it would occur distortedness situation on that mode. so this patch
set the word swap control bit of WINCONx to 1 as default value. but it
should be set to 0 in case that each ENLOCAL bit of WINCON0 ~ 2 registers
is enabled. this issue would be solved with local path feature soon.Signed-off-by: InKi Dae

As sysfs_notify_dirent has been made irq safe, there is no reason to not
call it directly from irq. With the work_struct removed, the remaining
element in poll_desc is a sysfs_dirent pointer which may not be NULL. We
can therefore store it directly in the idr and pass it as context to the
irq handler.Most part of the patch deals with renaming defines and variables to
reflect their new use without functional change.I also took the opportunity to initialize the idr statically.

The gpios on the max730x chips have support for internal pullups while in
input mode.This patch adds support for configuring these pullups via platform data.
A new member ("input_pullup_active") to the platform data struct is
introduced. A set bit in this variable activates the pullups while the
respective port is in input mode. This is a compatible enhancement since
unset bits lead to disables pullups which was the default in the original
driver._Note_: the 4 lowest bits in "input_pullup_active" are unused because the
first 4 ports of the controller are not used, too.Signed-off-by: Marc Kleine-Budde
