This patch adds a hook in drm_connector_helper_funcs to get the
support of the driver for adaptive sync functionality.
This can be called in the connector probe helper function after
the connector detect() and get_modes() hooks to also
query the adaptive sync support of the driver.

Because period and duty cycle are defined in the PWM framework structs as ints
with units of nanoseconds, the maximum time duration that can be set is limited
to ~2.147 seconds. Consequently, applications desiring to set greater time

While we expose the ability to turn off hardware dithering for nouveau,
we actually make the mistake of turning it on anyway, due to

Explicit synchronization is the future. At least, that seems to be what

I use vim
module_put() balances try_module_get(), not request_module(). Fix the
error path to match that.
Fixes: 2066facca4c7 ("drm/kms: slave encoder interface.")

sam,
i need some inputs on the below error. I had created this file
Documentation/devicetree/bindings/display/bridge/toshiba-tc358775.yaml
by using vim editor. Do we have any tool to create yaml file?
i do not get the error when running 'make dt_binding_check' in my

While converting I2C users to new APIs, I found a refcounting problem in
the encoder_slave implementation. This series fixes it and converts to
the new API.
Based on linux-next and only build tested.

This patch series is against next-20200317. It fixes all references to files
under Documentation/* that were moved, renamed or removed.
After this patch series, this script:
./scripts/documentation-file-ref-check
Doesn't complain about any broken reference.
