2015-02-04Smack: adds smackfs/ptrace interfaceLukasz Pawelczyk1-0/+10
This allows to limit ptrace beyond the regular smack access rules. It adds a smackfs/ptrace interface that allows smack to be configured to require equal smack labels for PTRACE_MODE_ATTACH access. See the changes in Documentation/security/Smack.txt below for details.

2015-02-04ASoC: rsnd: SSI + DMA can select BUSIFKuninori Morimoto1-0/+1
Sound data needs to be sent to R-Car sound SSI when playback. But, there are 2 interfaces for it. 1st is SSITDR/SSIRDR which are mapped on SSI. 2nd is SSIn_BUSIF which are mapped on SSIU. 2nd SSIn_BUSIF is used when DMA transfer, and it is always used if sound data came from via SRC. But, we can use it when SSI+DMA case too. (Current driver is assuming 1st SSITDR/SSIRDR for it) 2nd SSIn_BUSIF can be used as FIFO. This is very helpful/useful for SSI+DMA. But DMA address / DMA ID are not same between 1st/2nd cases. This patch care about these settings.

2015-02-04v4l: Support extending the v4l2_pix_format structureLaurent Pinchart2-4/+23
The v4l2_pix_format structure has no reserved field. It is embedded in the v4l2_framebuffer structure which has no reserved fields either, and in the v4l2_format structure which has reserved fields that were not previously required to be zeroed out by applications. To allow extending v4l2_pix_format, inline it in the v4l2_framebuffer structure, and use the priv field as a magic value to indicate that the application has set all v4l2_pix_format extended fields and zeroed all reserved fields following the v4l2_pix_format field in the v4l2_format structure. The availability of this API extension is reported to userspace through the new V4L2_CAP_EXT_PIX_FORMAT capability flag. Just checking that the priv field is still set to the magic value at [GS]_FMT return wouldn't be enough, as older kernels don't zero the priv field on return. To simplify the internal API towards drivers zero the extended fields and set the priv field to the magic value for applications not aware of the extensions.

2015-02-04ASoC: rsnd: care DMA slave channel name for DTKuninori Morimoto1-0/+1
Renesas sound driver is supporting to use DMAEngine. But, DMA slave channel name "tx", "rx" is not enough in DT case. Becuase, it has many ports and path combination. This patch adds rsnd_dma_of_name() to find DMA channel name, for example memory to SSI0 is "mem_ssi0", SSI0 to memory is "ssi0_mem", SSI0 to SRC0 is "ssi0_src0", SRC0 to SSI0 is "src0_ssi0", SRC0 to DVC0 is "src0_dvc0"... Renesas sound want to use PIO transfer mode for some reasons. It will be PIO tranfer mode if device node doesn't have DMA settings.

2015-02-04xhci-platform: Change compatible string from xhci-platform to generic-xhciHans de Goede1-2/+2
This brings the xhci-platform bindings in sync with what we've done for the ohci- and ehci-platform drivers. As discussed there using platform as a postfix is a bit weird as the platform bus is a Linux specific thing and the bindings are supposed to be OS agnostic. Note that the old xhci-platform compatible string is kept around for, well, compatibility reasons.

2015-02-04spi: sh-msiof: Add support for R-Car H2 and M2Geert Uytterhoeven1-2/+21
Add support for the MSIOF variant in the R-Car H2 (r8a7790) and M2 (r8a7791) SoCs. Binding documentation: - Add future-proof "renesas,msiof-<soctype>" compatible values, - The default for "renesas,rx-fifo-size" is 256 on R-Car H2 and M2, - "renesas,tx-fifo-size" and "renesas,rx-fifo-size" are deprecated for soctype-specific bindings, - Add example bindings. Implementation: - MSIOF on R-Car H2 and M2 requires the transmission of dummy data if data is being received only (cfr. "Set SICTR.TSCKE to 1" and "Write dummy transmission data to SITFDR" in paragraph "Transmit and Receive Procedures" of the Hardware User's Manual). - As RX depends on TX, MSIOF on R-Car H2 and M2 also lacks the RSCR register (Receive Clock Select Register), and some bits in the RMDR1 (Receive Mode Register 1) and TMDR2 (Transmit Mode Register 2) registers. - Use the recently introduced SPI_MASTER_MUST_TX flag to enable support for dummy transmission in the SPI core, and to differentiate from other MSIOF implementations in code paths that need this. - New DT compatible values ("renesas,msiof-r8a7790" and "renesas,msiof-r8a7791") are added, as well as new platform device names ("spi_r8a7790_msiof" and "spi_r8a7791_msiof"). - The default RX FIFO size is 256 words on R-Car H2 and M2. This is loosely based on a set of patches from Takashi Yoshii <takasi-y@ops.dti.ne.jp>.

2015-02-04ASoC: simple-card: overwrite cpu_dai->fmt with codec_dai->fmtNicolin Chen1-0/+6
The current simple-card driver separates the daimft for cpu_dai and codec_dai. So we might get different values for them (0x4003 and 0x1003 for example): asoc-simple-card sound-cs42888.12: cpu : 2024000.esai / 4003 / 132000000 asoc-simple-card sound-cs42888.12: codec : cs42888 / 1003 / 24576000 asoc-simple-card sound-cs42888.12: cs42888 <-> 2024000.esai mapping ok This is not allowed at all as we need to keep the DAIFMT settings identical for both the ends of the link. Thus this patch fixes it by overwriting the cpu_dai->fmt with codec_dai->fmt since we defined the DAIFMT_MASTER basing on CODEC at the first place while the other bits are same.
