2013-10-30simplefb: use write-combined remappingDavid Herrmann1-2/+2
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 Herrmann1-2/+10
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 Bates1-2/+2
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.

2013-10-09hyperv-fb: add pci stubGerd Hoffmann1-1/+39
This patch adds a pci stub driver to hyper-fb. The hyperv framebuffer driver will bind to the pci device then, so linux kernel and userspace know there is a proper kernel driver for the device active. lspci shows this for example: [root@dhcp231 ~]# lspci -vs8 00:08.0 VGA compatible controller: Microsoft Corporation Hyper-V virtual VGA (prog-if 00 [VGA controller]) Flags: bus master, fast devsel, latency 0, IRQ 11 Memory at f8000000 (32-bit, non-prefetchable) [size=64M] Expansion ROM at <unassigned> [disabled] Kernel driver in use: hyperv_fb Another effect is that the xorg vesa driver will not attach to the device and thus the Xorg server will automatically use the fbdev driver instead.

2013-10-09omapdss: HDMI: Use OMAP4 HDMI core functions directly and remove hdmi_ip_opsArchit Taneja6-184/+162
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.

HDMI PHY is a block common to DSS in OMAP4, OMAP5 and DRA7x. Move the existing functions from ti_hdmi_4xxx_ip.c to a separate file. These funcs are called directly from the hdmi driver rather than hdmi_ip_ops function pointer calls. Add the PHY library function declarations to ti_hdmi.h. These will be shared amongst the omap4/5 hdmi platform drivers. Remove the PHY function pointer ops from the ti_hdmi_ip_ops struct.

HDMI wrapper is a block common to DSS in OMAP4, OMAP5 and DRA7x. Move the existing functions from ti_hdmi_4xxx_ip.c to a separate file. These funcs are called directly from the hdmi driver rather than hdmi_ip_ops funtion pointer calls. Add new wrapper funcs which can be used by other hdmi libraries like core, pll and phy. Move some of the enums, structs and funcs related to the wrapper from ti_hdmi_4xxx_ip.h to ti_hdmi.h. These will be shared amongst the omap4/5 hdmi platform drivers and other libraries. The old hdmi_wp_init() is removed since it didn't do anything. Timing parameters like interlace, hsync_level and vsync_level weren't copied correctly before. Those are copied correctly now. 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.
