| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* clk: convert API to match reset/mailbox styleStephen Warren2016-06-19-17/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The following changes are made to the clock API: * The concept of "clocks" and "peripheral clocks" are unified; each clock provider now implements a single set of clocks. This provides a simpler conceptual interface to clients, and better aligns with device tree clock bindings. * Clocks are now identified with a single "struct clk", rather than requiring clients to store the clock provider device and clock identity values separately. For simple clock consumers, this isolates clients from internal details of the clock API. * clk.h is split so it only contains the client/consumer API, whereas clk-uclass.h contains the provider API. This aligns with the recently added reset and mailbox APIs. * clk_ops .of_xlate(), .request(), and .free() are added so providers can customize these operations if needed. This also aligns with the recently added reset and mailbox APIs. * clk_disable() is added. * All users of the current clock APIs are updated. * Sandbox clock tests are updated to exercise clock lookup via DT, and clock enable/disable. * rkclk_get_clk() is removed and replaced with standard APIs. Buildman shows no clock-related errors for any board for which buildman can download a toolchain. test/py passes for sandbox (which invokes the dm clk test amongst others).

| * 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The DMA was outputting the palette on the screen because the base for the DMA was not after the palette. In addition to that, the ceiling was also too high, this led that the output on the screen was shifted. NOTE: According to the TRM, even in 16/24bit mode a palette is required in the first 32 bytes of the framebuffer. See also: https://e2e.ti.com/support/arm/sitara_arm/f/791/p/234967/834483#834483 "In this mode, the LCDC will assume all information is data and thus you need to ensure that the DMA points to the first pixel of data and not the first entry in the frame buffer which is the beginning of the 512 byte palette."

| | | | | | | | | | | | | | | | | | | selected The behavior before this patch would attempt to configure the mux setting for pins 0 to 27 on PORTD to all be setting 3 for LVDS. The LVDS interface actually only uses pins 18 to 27 and not pins 0 to 27 as in the parallel LCD interface. This patch restricts the configuration to only the relevant pins 18 to 27 on PORTD. This was tested on a sun8i A33 tablet with an LVDS screen. MMC1 has the capability to use pins 2 to 7 on PORTD and the mux on those pins was being inadvertently set to setting 3 for MMC functionality which this patch corrects.
