drm/bridge: analogix_dp: Split bind() into probe() and real bind()

2020-05-10T08:32:41+00:00

[ Upstream commit 83a196773b8bc6702f49df1eddc848180e350340 ]

Analogix_dp driver acquires all its resources in the ->bind() callback,
what is a bit against the component driver based approach, where the
driver initialization is split into a probe(), where all resources are
gathered, and a bind(), where all objects are created and a compound
driver is initialized.

Extract all the resource related operations to analogix_dp_probe() and
analogix_dp_remove(), then call them before/after registration of the
device components from the main Exynos DP and Rockchip DP drivers. Also
move the plat_data initialization to the probe() to make it available for
the analogix_dp_probe() function.

This fixes the multiple calls to the bind() of the DRM compound driver
when the DP PHY driver is not yet loaded/probed:

drm/rockchip: fix integer type used for storing dp data rate

2020-01-13T13:31:59+00:00

commit 2589c4025f13 ("drm/rockchip: Avoid drm_dp_link helpers") changes
the type of variables used to store the display port data rate and
number of lanes to u8. However u8 is not sufficient to store the link
data rate of the display port.
This commit reverts the type of data rate to unsigned int.

Reorganize a bit the functions order to clarify the driver and separate
hardware independent and specific functions a bit. This change only moves

these helpers are called, check the returned value and print an error

drm/rockchip: lvds: Create an RK3288 specific probe function

2020-01-05T11:38:54+00:00

The probe function is highly adapted to the RK3288 specificities, move
all specific bits into an "rk3288_probe" function, also part of the
platform data.

The goal is to ease the addition of new flavors of Rockchip LVDS IPs.

drm/rockchip: lvds: Change platform data to hold helper_funcs pointer

2020-01-05T11:12:39+00:00

Prepare the introduction of PX30 support by using
drm_encoder_helper_funcs as platform data instead of multiple register
names which are specific to rk3288 and not generic to all Rockchip
IPs. This way adding support for a new flavor of a similar IP will be
a matter of adding the relevant helper funcs.
