2015-11-19video: adf: build fixes for 4.1Amit Pundir
Couple of ADF build fixes for v4.1 adf/adf_fops.c fix: get_unused_fd() is obsolete, use get_unused_fd_flags(O_CLOEXEC) instead to allocate a default file descriptor. This fix is a followup of upstream commit f938612dd97d "include/linux/file.h: remove get_unused_fd() macro". adf/adf_memblock.c fix: Fix dma_buf_export() call. Based on mainline commit d8fbe341beb6 "dma-buf: cleanup dma_buf_export() to make it easily extensible". Otherwise we run into following build failures: ---------- CC drivers/video/adf/adf_fops.o CC drivers/video/adf/adf_memblock.o drivers/video/adf/adf_memblock.c: In function ‘adf_memblock_export’: drivers/video/adf/adf_memblock.c:154:2: warning: passing argument 1 of ‘dma_buf_export’ from incompatible pointer type [enabled by default] In file included from drivers/video/adf/adf_memblock.c:15:0: include/linux/dma-buf.h:211:17: note: expected ‘const struct dma_buf_export_info *’ but argument is of type ‘struct adf_memblock_pdata *’ drivers/video/adf/adf_memblock.c:154:2: error: too many arguments to function ‘dma_buf_export’ In file included from drivers/video/adf/adf_memblock.c:15:0: include/linux/dma-buf.h:211:17: note: declared here make[3]: *** [drivers/video/adf/adf_memblock.o] Error 1 make[3]: *** Waiting for unfinished jobs.... drivers/video/adf/adf_fops.c: In function ‘adf_device_post_config’: drivers/video/adf/adf_fops.c:228:2: error: implicit declaration of function ‘get_unused_fd’ [-Werror=implicit-function-declaration] cc1: some warnings being treated as errors make[3]: *** [drivers/video/adf/adf_fops.o] Error 1 make[2]: *** [drivers/video/adf] Error 2 make[2]: *** Waiting for unfinished jobs.... ---------- Signed-off-by: Amit Pundir <amit.pundir@linaro.org>

2015-11-19video: adf: use rb_erase in adf_obj_destroy.Alistair Strachan
Not calling rb_erase() can cause slab corruption, as the rb_first() call after kfree() in adf_obj_destroy() can return the same node twice unless it is erased. This problem was reproduced by unloading a kernel module that used the adf framework *after* a vsync event was registered. A crash would occur in rb_first(). (Just loading and immediately unloading the module without the vsync event worked correctly.)

2015-11-19video: adf: add buffer padding quirkGreg Hackmann
Quirks specify common behaviors that vary slightly among devices, and which ADF must account for. The buffer padding quirk captures the way different devices fetch the last scanline in a buffer: some devices fetch an entire line (including padding to the pitch) while others only fetch up to the visible width. ADF's buffer size validation now takes this quirk into account. Change-Id: I828b13316e27621d8a9efd9d5fffa6ce12a525ff Signed-off-by: Greg Hackmann <ghackmann@google.com>

2015-11-19video: adf: ensure consistent alignment on userspace facing structsGreg Hackmann
64-bit types in structs create alignment problems when a 32-bit x86 userspace talks to an x86_64 kernel. In most cases the 64-bit types can be replaced with 32-bit ones, since they're being used for fds and should have been __s32 in the first place. For adf_vsync_event, alignment can be enforced by making the timestamp an __aligned_u64. Change-Id: I87cf73d8f57730bd7bb43ffce6b7b411eb0ff198 Signed-off-by: Greg Hackmann <ghackmann@google.com>
2015-11-19video: adf: replace fbdev helper's open flag with refcountGreg Hackmann
A device's fb_info is shared between clients. fb_release() is called when each client is released, not just the last one. Since the fbdev helper needs to release its dma-buf when the last client goes away, it must keep its own reference count. fbmem and fbcon hold different locks while calling fb_release(), so explicit locking is needed.

for-next Pull of-graph helpers from Philipp Zabel: of: Add of-graph helpers to loop over endpoints and find ports by id This series converts of_graph_get_next_endpoint to decrement the refcount of the passed prev parameter. This allows to add a for_each_endpoint_of_node helper macro to loop over all endpoints in a device tree node. The of_graph_get_port_by_id function is added to retrieve a port by its known port id (contained in the reg property) from the device tree.
2015-03-23powerpc: Move Power Macintosh drivers to generic byteswappersDavid Gibson
ppc has special instruction forms to efficiently load and store values in non-native endianness. These can be accessed via the arch-specific {ld,st}_le{16,32}() inlines in arch/powerpc/include/asm/swab.h. However, gcc is perfectly capable of generating the byte-reversing load/store instructions when using the normal, generic cpu_to_le*() and le*_to_cpu() functions eaning the arch-specific functions don't have much point. Worse the "le" in the names of the arch specific functions is now misleading, because they always generate byte-reversing forms, but some ppc machines can now run a little-endian kernel. To start getting rid of the arch-specific forms, this patch removes them from all the old Power Macintosh drivers, replacing them with the generic byteswappers.

2015-03-17fbdev: kconfig: replace PPC_OF with PPCKevin Hao
The PPC_OF is a ppc specific option which is used to mean that the firmware device tree access functions are available. Since all the ppc platforms have a device tree, it is aways set to 'y' for ppc. So it makes no sense to keep a such option in the current kernel. Replace it with PPC.

The OF functionality has moved to a common place and be used by many archs. So we don't need to include the ppc arch specific header files and depend on PPC_OF option any more. This is a preparation for killing PPC_OF.
