| * video: Add simple-panel supportSascha Hauer2015-07-133-0/+170
| | | | | | | | | | | | | | | | | | | | This adds support for simple panels. These are panels which don't need special handling but can have enable gpios and such. Unlike the Linux kernel implementation this one is able to understand display-timings nodes so that it's not necessary to keep a list of all known displays with their corresponding timings in barebox.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From this Linux commit: commit 85de9d17c485c4196f74d45de2206d4802f8a3be Author: Denis Carikli <denis@eukrea.com> Date: Mon Apr 7 14:44:43 2014 +0200 imx-drm: match ipu_di_signal_cfg's clk_pol with its description. According to the datasheet, setting the di0_polarity_disp_clk field in the GENERAL di register sets the output clock polarity to active high.

| * video: ipuv3: Replace ipu_output with VPLSascha Hauer2015-07-135-178/+197
| | | | | | | | | | | | | | | | The ipuv3 makes heavy use of video encoders internally to the SoC but also external encoders are common. Switch to VPL support to be able to handle these properly. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * video: Add MTL017 LVDS encoder supportSascha Hauer2015-07-133-0/+290
| | | | | | | | | | | | | | | | The MTL017 is found on the Efika Smartbook. Not much is known about this chip, so this driver only programs a register dump which is suitable for some panels. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * video: Add Video Pipeline (VPL) supportSascha Hauer2015-07-133-0/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Complex video pipelines are modelled with the of_graph bindings in the devicetree. This patch adds a ioctl infrastructure to issue commands to the remote endpoint of a of_graph. Currently defined ioctls are prepare/unprepare, enable/disable and get_modes. This is enough to control LVDS or HDMI encoder or simple panels. A device node which contains of_graph endpoints can be registered as a VPL entity. An entity can receive ioctls via the .ioctl callback and also issue ioctls by calling vpl_ioctl. The core itself will never iterate over the entire pipeline. Instead, the different VPL entities should forward an ioctl to the next instance in the pipeline whenever necessary. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* 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. Part of the patch was done using the 'coccinelle' tool with the following semantic patch: @rule1@ identifier dev; identifier type; identifier func; @@ func(...) { <... - dev_get_drvdata(dev, (unsigned long *)&type) + dev_get_drvdata(dev, (const void **)&type) ...> } @rule2@ identifier dev; identifier type; identifier func; identifier data; @@ func(...) { <... - dev_get_drvdata(dev, (unsigned long *)&type->data) + dev_get_drvdata(dev, (const void **)&type->data) ...> } Signed-off-by: Antony Pavlov <antonynpavlov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* sandbox: allow "make ARCH=sandbox allyesconfig"Holger Schurig2014-07-221-0/+1
| | | | | | | | | | | | | Compiling the tree with allyesconfig is helpful because different compilers (gcc, clang) or static checkers (e.g. clang's scan-build) can then process and check more code. This patch introduces two new configuration symbols that Kconfig files can depend on. That way, code that is only working where a cache or DMA implementation exists can be opted out.
