* video: IPUv3-LDB: demote dual-channel message to info levelLucas Stach2018-04-091-1/+1
| | | | | | | | Dual channel mode is a valid mode of operation, so there is no reason to print this at the warning level. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* video: IPUv3-LDB: fix dual-channel modeLucas Stach2017-07-201-13/+33
| | | | | | | | For the dual-channel mode to work correctly, both channels need to be muxed to the same DI and both clock branches need to be configured correctly. Signed-off-by: Lucas Stach <l.stach@pengutronix.de>
* video: select OFTREE from DRIVER_VIDEO_IMX_IPUV3Lucas Stach2017-05-171-0/+1
| | | | | | | | DRIVER_VIDEO_IMX_IPUV3 selects VIDEO_VPL, which has a hard dependency on OFTREE, so it is required to select this one, too. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* video: ipu: register framebuffer, even when no modes are foundSascha Hauer2017-04-031-3/+1
| | | | | | | | | When no monitor is connected it might be normal that no modes are found. Do not bail out with an error in this case, which gives an ugly error message, but instead still register the framebuffer. This gives the user a chance to examine it and see that the framebuffer has no modes. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* video: ipu: convert "failed to get modes" message to dev_dbgSascha Hauer2017-04-031-1/+1
| | | | | | | | When no monitor is connected the it's normal for some outputs that no modes can be found. Convert dev_err to dev_dbg to decrease the visibility of this message. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* video: add VPL ioctl to get bus formatPhilipp Zabel2016-08-251-2/+6
| | | | | | | | | The i.MX specific DI_MODE VPL ioctl already allows to query the encoder input bus format. This patch also allows non-i.MX specific encoder drivers to report their input bus format.

* video: switch to media bus formatsPhilipp Zabel2016-08-256-28/+28
| | | | | | | | | | | V4L2 pixel formats are supposed to describe video frames in memory. To describe the pixel format on the hardware bus between display interface and encoders, use media bus formats, which are more expressive. This allows to get rid of the custom GBR24 and LVDS666 fourccs. Signed-off-by: Philipp Zabel <p.zabel@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* string: Fix (v)asprintf prototypesSascha Hauer2016-04-153-7/+6
| | | | | | | | | | Our asprintf and vasprintf have different prototypes than the glibc functions. This causes trouble when we want to share barebox code with userspace code. Change the prototypes for (v)asprintf to match the glibc prototypes. Since the current (v)asprintf are convenient to use change the existing functions to b(v)asprintf.

* video: i.MX IPUv3: Set ldb clocks correctlySascha Hauer2015-11-301-4/+22
| | | | | | | | | | | | The clocks for the LVDS display bridge have a fixed /3.5 and a configurable /1,/2 divider in their path. The configurable divider has to be explicitly configured for single/dual channel support, so we can't rely on clock rate parent propagation here. Clear the CLK_SET_RATE_PARENT flag for the configurable divider and configure the clock explicitly in the ldb driver. Tested on a custom i.MX6 board, currently untested on i.MX53.

| | | | | | | | | | | | | | | | | | | | putting an error pointer into strerror can be a bit confusing since strerror takes a positive error code but PTR_ERR returns a negative number, so we have to do strerror(-PTR_ERR(errp)).

| | | | | | | | | This syncs the imx-hdmi driver with Linux 4.2-rc1 where it makes sense. This makes it easier to compare the driver with the kernel. This also adds hdmi_av_composer which is mandatory. Somehow the driver worked without it in lower resolutions, but now it also works for higher resolutions.

* of: use 'const void *' for struct of_device_id.dataAntony Pavlov2015-04-303-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Since 2011 barebox' of_device_id struct uses unsigned long type for data field: struct of_device_id { char *compatible; unsigned long data; }; Almost always struct of_device_id.data field are used as pointer and need 'unsigned long' casting. E.g. see 'git grep -A 4 of_device_id drivers/' output: drivers/ata/sata-imx.c:static __maybe_unused struct of_device_id imx_sata_dt_ids[] = { drivers/ata/sata-imx.c- { drivers/ata/sata-imx.c- .compatible = "fsl,imx6q-ahci", drivers/ata/sata-imx.c- .data = (unsigned long)&data_imx6, drivers/ata/sata-imx.c- }, { Here is of_device_id struct in linux kernel v4.0: struct of_device_id { char name[32]; char type[32]; char compatible[128]; const void *data; }; Changing of_device_id.data type to 'const void *data' will increase barebox' linux kernel compatibility and decrease number of 'unsigned long' casts.
