Commit 4710b752 ("[media] v4l: Add Renesas R-Car FDP1 Driver") in the v4l-dvb tree adds CONFIG_VIDEO_RENESAS_FDP1. It calls into the FCP driver, but when there is no dependency, FCP might be a module while FDP1 is built-in. We have the same logic in VIDEO_RENESAS_VSP1, which also depends on FCP not being a module when it is built-in itself. drivers/media/platform/rcar_fdp1.o: In function `fdp1_pm_runtime_resume': rcar_fdp1.c:(.text.fdp1_pm_runtime_resume+0x78): undefined reference to `rcar_fcp_enable' drivers/media/platform/rcar_fdp1.o: In function `fdp1_pm_runtime_suspend': rcar_fdp1.c:(.text.fdp1_pm_runtime_suspend+0x14): undefined reference to `rcar_fcp_disable' drivers/media/platform/rcar_fdp1.o: In function `fdp1_probe': rcar_fdp1.c:(.text.fdp1_probe+0x15c): undefined reference to `rcar_fcp_get' Signed-off-by:

This function is too big and too complex, making really hard to understand what's there. Split it into sub-routines, in order to make it easier to be understood, and to allow gcc to better parse it. As a bonus, it gets rid of a goto in the middle of a routine. Signed-off-by: -

The dvb_net code has a really complex function, meant to handle DVB network packages: it is long, has several loops and ifs inside, and even cause warnings with gcc5. Prepare it to be split into smaller functions by storing all arguments and internal vars inside a struct. Signed-off-by:

When building with "make W=1", we get multiple harmless build warnings for the vpfe driver: drivers/staging/media/davinci_vpfe/dm365_resizer.c:241:1: error: 'static' is not at beginning of declaration [-Werror=old-style-declaration] drivers/staging/media/davinci_vpfe/dm365_resizer.c: In function 'resizer_set_defualt_configuration': drivers/staging/media/davinci_vpfe/dm365_resizer.c:831:16: error: initialized field overwritten [-Werror=override-init] drivers/staging/media/davinci_vpfe/dm365_resizer.c:831:16: note: (near initialization for 'rsz_default_config.rsz_rsc_param[0].h_typ_c') drivers/staging/media/davinci_vpfe/dm365_resizer.c:849:16: error: initialized field overwritten [-Werror=override-init] drivers/staging/media/davinci_vpfe/dm365_resizer.c:849:16: note: (near initialization for 'rsz_default_config.rsz_rsc_param[1].h_typ_c') All of them are trivial to fix without changing the behavior of the driver, as "static const" is interpreted the same as "const static", and VPFE_RSZ_INTP_CUBIC is defined as zero, so the initializations are not really needed.

It has never been possible to actually build this driver as a loadable module, only built-in because the Makefile attempts to build each file into its own module and fails: ERROR: "mbus_to_pix" [drivers/staging/media/davinci_vpfe/vpfe_video.ko] undefined! ERROR: "vpfe_resizer_register_entities" [drivers/staging/media/davinci_vpfe/vpfe_mc_capture.ko] undefined! ERROR: "rsz_enable" [drivers/staging/media/davinci_vpfe/dm365_resizer.ko] undefined! ERROR: "config_ipipe_hw" [drivers/staging/media/davinci_vpfe/dm365_ipipe.ko] undefined! ERROR: "ipipe_set_lutdpc_regs" [drivers/staging/media/davinci_vpfe/dm365_ipipe.ko] undefined! It took a long time to catch this bug with randconfig builds because at least 14 other Kconfig symbols have to be enabled in order to configure this one, and it was clearly only ever tested as built-in with mainline kernels, if at all. The solution is really easy: this patch changes the Makefile to link all files into one module. As discussed previously, the driver has never before used successfully as a loadable module, but there is no reason to prevent that configuration.

In randconfig builds that select VIDEO_EM28XX_V4L2 and MEDIA_SUBDRV_AUTOSELECT, but not MEDIA_CAMERA_SUPPORT, we get a Kconfig warning: warning: (VIDEO_EM28XX_V4L2) selects VIDEO_MT9V011 which has unmet direct dependencies (MEDIA_SUPPORT && I2C && VIDEO_V4L2 && MEDIA_CAMERA_SUPPORT) This avoids the warning by making that 'select' conditional on MEDIA_CAMERA_SUPPORT. Alternatively we could mark EM28XX as 'depends on MEDIA_CAMERA_SUPPORT', but it does not seem to have any real dependency on that itself. Signed-off-by:

If MEDIA_SUBDRV_AUTOSELECT and VIDEO_GO7007 are both set, we automatically select VIDEO_OV7640, but that depends on MEDIA_CAMERA_SUPPORT, so we get a Kconfig warning if that is disabled: warning: (VIDEO_GO7007) selects VIDEO_OV7640 which has unmet direct dependencies (MEDIA_SUPPORT && I2C && VIDEO_V4L2 && MEDIA_CAMERA_SUPPORT) This adds another dependency so we don't accidentally select it when it is unavailable.

The stv090x driver uses the lookup table for signal strength already, with this patch we use the lookup tables for carrier/noise ratio as well. This has the advantage, that values for DVB-S and DVB-S2 are now corresponding, while before they were way off. The values are now proportional to real carrier/noise ratio, while before they were corresponding to register values. So now applications are able to give the user real carrier/noise ratio. Because the output has to be within 0x0000...0xFFFF the three negative values for DVB-S2 are omitted. This is no significant loss, because reception is lost at 7.5 dB already (TT S2-1600, Cine S2), so the negative values are not really important, and also for DVB-S they don´t exist. Signed-off-by:

Remove DVB-T2 BER as it does not work at all and I didn't find how to fix. Fix DVB-T and DVB-C BER. It seems to return new some realistic looking values. Use (1 << 24) base for CNR calculations to keep it in line with dvb logarithm functions. Move all statistic logic to mn88473_read_status() function. Use regmap_bulk_read() for reading multiple registers as a one go. Many more and less minor changes. Cc: Martin Blumenstingl <martin.blumenstingl@googlemail.com> Signed-off-by:

The VPE was restricting the number of plane per buffer based on the fact that if a particular format had color separation it was meant to need 2 planes. However NV12/NV16 are color separate format which are meant to be presented in a single contiguous buffer/plane. It could also be presented in a multi-plane as well if need be. So we must support both modes for more flexibility. The number of plane requested by user space was previously ignored and was therefore always overwritten. The driver now use the requested num plane as hint to calculate needed offset when required. Signed-off-by:
