2013-10-30simplefb: use write-combined remappingDavid Herrmann
Framebuffers shouldn't be cached and it is usually very uncommon to read them. Therefore, use ioremap_wc() to get significant speed improvements on systems which provide it. On all other systems it's aliased to ioremap_nocache() which is also fine.

2013-10-30simplefb: fix unmapping fb during destructionDavid Herrmann
Unfortunately, fbdev does not create its own "struct device" for framebuffers. Instead, it attaches to the device of the parent layer. This has the side-effect that devm_* managed resources are not cleaned up on framebuffer-destruction but rather during destruction of the parent-device. In case of fbdev this might be too late, though. remove_conflicting_framebuffer() may remove fbdev devices but keep the parent device as it is. Therefore, we now use plain ioremap() and unmap the framebuffer in the fb_destroy() callback. Note that we must not free the device here as this might race with the parent-device removal. Instead, we rely on unregister_framebuffer() as barrier and we're safe.

2013-10-29efifb: prevent null-deref when iterating dmi_listJames Bates
The dmi_list array is initialized using gnu designated initializers, and therefore may contain fewer explicitly defined entries as there are elements in it. This is because the enum above with M_xyz constants contains more items than the designated initializer. Those elements not explicitly initialized are implicitly set to 0. Now efifb_setup() loops through all these array elements, and performs a strcmp on each item. For non explicitly initialized elements this will be a null pointer: This patch swaps the check order in the if statement, thus checks first whether dmi_list[i].base is null.

After removing wrapper, pll and phy funcs from ti_hdmi_4xxx_ip.c, we are left with OMAP4 HDMI core functions. Use these directly in hdmi.c rather than using hdmi_ip_ops. Rename the core functions with a 'hdmi4' suffix. We used to have hdmi_ip_ops so that one could support HDMI within a TI SoC which had a non-DSS display subsytem. This however never got put into use, and hence these ops aren't useful any more. The DT/hwmod information for hdmi doesn't split the address space according to the required sub blocks. Keep the address offset and size information in the driver for now. This will be removed when the driver gets the information correctly from DT/hwmod.
