According to 'drivers/gpu/drm/drm_drv.c', 'drm_dev_unref()' is just a compatibility alias for 'drm_dev_put()'. So use the latter instead. Signed-off-by:

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.

Instead of using timer and spinlocks, use delayed_work and mutexes for rockchip psr. This allows us to make blocking calls when enabling/disabling psr (which is sort of important given we're talking over dpcd to the display).

There's a race between when bridge_disable and when vop_crtc_disable are called. If the flush timer triggers a new psr work between these, we will operate eDP without power shutdowned by bridge_disable.

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:

DRM_MODE_PROP_PENDING is not used anywhere (except printed out by libdrm proptest/modetest). This seems to be yet another thing blindly copied from xrandr. Quoting from the protocol spec: "If 'pending' is TRUE, changes made to property values with RRChangeOutputProperty will be saved in the pending property value and be automatically copied to the current value on the next RRSetCrtcConfig request involving the named output. If 'pending' is FALSE, changes are copied immediately." So it was some kind of early idea for atomic property updates. Signed-off-by:
