* watchdog: imxwd: remove remove callbackSascha Hauer2015-08-261-12/+0
| | | | | | | | | The imxwd is for resetting the system, so we should not unregister it during shutdown_barebox() as it may leave us without a restart handler. Only a bug (not setting reset_wd to NULL in remove()) made the whole thing work. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* param_enum: protect against invalid valuesSascha Hauer2015-08-261-2/+6
| | | | | | | | Since dev_add_param_enum is passed a pointer containing the actual value it can contain an invalid value. Protect against it so that we do not access invalid array elements. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * 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.

| * video: ipuv3: match ipu_di_signal_cfg's clk_pol with its descriptionSascha Hauer2015-07-132-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Add Video Pipeline (VPL) supportSascha Hauer2015-07-135-0/+166
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This enabled multi image support for the Garz&Fricke Vincell board. Also it adds the Vincell-LT as a second image with a separate device tree. Previously we used the same image on both the Vincell and the Vincell-LT image since the differences are not that significant for barebox. Still this was good for quite some confusion internally, so let's properly introduce a second image.

It's not easy to find a correct value for this register, it seems it depends on the used external reference frequency and some other 'magic' things. There are some values out in the wild for the 33,333333 MHz and 33,333000 MHz reference frequency case, but they are not consistent over the boards. The value used here in this change for the USB PLL register is from the first days of support for this platform and works at least on the reference baseboard.
