* sunxi: display: Use PWM to drive backlight where applicableHans de Goede2016-08-26-0/+11
| | | | | | | | | | | | | | | | | | | | | When the backlight's pwm input is connected to a pwm output of the SoC, actually use pwm to drive the backlight. The mean reason for doing this is to fix the backlight turning off for aprox. 1 second while the kernel is booting. This is caused by the kernel actually using pwm to drive the backlight, so that it can dim the backlight. First the pwm driver loads and switches the pinmux for the pin driving the backlight's pwm input to the pwm controller. Then about 1s later the actual backlight driver loads and tells the pwm driver to actually update the pwm settings, which have a power-on-reset value of "off". An additional advantage is that this allows us to initatiate the backlight at 80%, which is the kernel default, avoiding a brightness change while the kernel loads.

* 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.

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."
