* dm: core: Replace of_offset with accessorSimon Glass2017-02-08-2/+2
| | | | | | | | | At present devices use a simple integer offset to record the device tree node associated with the device. In preparation for supporting a live device tree, which uses a node pointer instead, refactor existing code to access this field through an inline function.

* video: tegra: Move to using simple-panel and pwm-backlightSimon Glass2016-07-05-263/+49
| | | | | | | | | | | | | | | | | | We have standard drivers for panels and backlights which can do most of the work for us. Move the tegra20 LCD driver over to use those instead of custom code. This patch includes device tree changes for the nvidia boards. I have only been able to test seaboard. If this patch is applied, these boards will also need to be synced with the kernel, and updated to use display-timings: - colibri - medcom-wide - paz00 - tec Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
* video: tegra: refuse to bind to disabled dcsStephen Warren2016-05-17-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This prevents the following boot-time message on any board where only the first DC is in use, yet the DC's DT node is enabled: stdio_add_devices: Video device failed (ret=-22) (This happens on at least Harmony, Ventana, and likely any other Tegra20 board with display enabled other than Seaboard). The Tegra DC's DT node represents a display controller. It may itself drive an integrated RGB display output, or be used by some other display controller such as HDMI. For this reason the DC node itself is not enabled/disabled in DT; the DC itself is considered a shared resource, not the final (board-specific) display output. The node should instantiate a display output driver only if the rgb subnode is enabled. Other output drivers are free to use the DC if they are enabled and their DT node references the DC's DT node. Adapt the Tegra display drivers' bind() routine to only bind to the DC's DT node if the RGB subnode is enabled. Now that the display driver does the right thing, remove the workaround for this issue from Seaboard's DT file.

* of: clean up OF_CONTROL ifdef conditionalsMasahiro Yamada2015-08-18-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | We have flipped CONFIG_SPL_DISABLE_OF_CONTROL. We have cleansing devices, $(SPL_) and CONFIG_IS_ENABLED(), so we are ready to clear away the ugly logic in include/fdtdec.h: #ifdef CONFIG_OF_CONTROL # if defined(CONFIG_SPL_BUILD) && !defined(SPL_OF_CONTROL) # define OF_CONTROL 0 # else # define OF_CONTROL 1 # endif #else # define OF_CONTROL 0 #endif Now CONFIG_IS_ENABLED(OF_CONTROL) is the substitute. It refers to CONFIG_OF_CONTROL for U-boot proper and CONFIG_SPL_OF_CONTROL for SPL. Also, we no longer have to cancel CONFIG_OF_CONTROL in include/config_uncmd_spl.h and scripts/Makefile.spl.

* video: tegra: Update line length to match resolutionThierry Reding2013-01-16-2/+2
| | | | | | | | | | | | | | | Instead of storing the computed line length in a local variable, store it in the global lcd_line_length variable to make sure the LCD subsystem can properly draw content for the display resolution. This probably wasn't noticed yet because the only board where LCD support is currently enabled is Seaboard, which runs at a 1366x768 resolution. As it happens this is the maximum resolution supported and also the default that is used to initialize the framebuffer before the configuration from DT is available.
