We leave PCI devices not bound to a driver in D0 during runtime suspend. But they may have a parent which is bound and can be transitioned to D3cold at runtime. Once the parent goes to D3cold, the unbound child may go to D3cold as well. When the child goes to D3cold, its internal state, including configuration of BARs, MSI, ASPM, MPS, etc., is lost. One example are recent hybrid graphics laptops which cut power to the discrete GPU when the root port above it goes to ACPI power state D3. Users may provoke this by unbinding the GPU driver and allowing runtime PM on the GPU via sysfs: The PM core will then treat the GPU as "suspended", which in turn allows the root port to runtime suspend, causing the power resources listed in its _PR3 object to be powered off. The GPU's BARs will be uninitialized when a driver later probes it. Another example are hybrid graphics laptops where the GPU itself (rather than the root port) is capable of runtime suspending to D3cold. If the GPU's integrated HDA controller is not bound and the GPU's driver decides to runtime suspend to D3cold, the HDA controller's BARs will be uninitialized when a driver later probes it. Fix by saving and restoring config space over a runtime suspend cycle even if the device is not bound. Acked-by:

This patch adds support for DMT display modes over HDMI. The modes timings configurations are from the Amlogic Vendor linux tree and tested over multiples monitors. Previously only a selected number of CEA modes were supported. Only these following modes are supported with these changes: - 640x480@60Hz - 800x600@60Hz - 1024x768@60Hz - 1152x864@75Hz - 1280x1024@60Hz - 1600x1200@60Hz - 1920x1080@60Hz The associated code to handle the clock rates is also added.

Convert the sharp lq123p1jx31 from using a fixed mode to specifying a display timing with min/typ/max values. This allows us to capture the timings set forth in the datasheet as well as the additional values that we've cleared with the display vendor to avoid interference with the digitizer on the Samsung Chromebook Plus (kevin). A follow-on patch will specify the override mode for kevin devices.

We were previously selecting 1024x768 and 32BPP as the default set-up for the PL111 consumers. This does not work on elder systems: the device tree bindings support a property "max-memory-bandwidth" in bytes/second that states that if you exceed this the memory bus will saturate. The result is flickering and unstable images. Parse the "max-memory-bandwidth" and respect it when intializing the driver. On the RealView PB11MP, Versatile and Integrator/CP we get a nice console as default with this code. Reviewed-by:

The following happens when connection a DVI output driven from the SiI9022 using a DVI-to-VGA adapter plug: i2c i2c-0: sendbytes: NAK bailout. i2c i2c-0: sendbytes: NAK bailout. Then no picture. Apparently the I2C engine inside the SiI9022 is not smart enough to try to fall back to DDC I2C. Or the vendor have not integrated the electronics properly. I don't know which one it is. After this, the I2C bus seems stalled and the first attempt to read the status register fails, and the code returns with negative return value, and the display fails to initialized. Instead, retry status readout five times and continue even if this fails. Tested on the ARM Versatile Express with a DVI-to-VGA connector, it now gives picture. Introduce a helper struct device *dev variable to make the code more readable. Cc: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by:

We want to cut down the default bpp to 16 on the RealView so we can have a 1024x768 framebuffer console by default. The memory bandwidth limitations makes this not work with the PL111 default of 32bpp. This builds on top of the earlier patches making the framebuffer default bpp a per-variant variable. Reviewed-by:

Linus Walleij authored
The PL110, Integrator and Versatile boards strongly prefer to use 16 BPP even if other modes are supported, both to keep down memory consumption and also to easier find a good match to supported resolutions with consideration taken to the memory bandwidth of the platforms. Reviewed-by:
