2020-04-09drm/bridge: analogix_dp: Split bind() into probe() and real bind()Marek Szyprowski3-40/+58
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] Exynos DRM: using 14400000.fimd device for DMA mapping operations exynos-drm exynos-drm: bound 14400000.fimd (ops fimd_component_ops [exynosdrm]) exynos-drm exynos-drm: bound 14450000.mixer (ops mixer_component_ops [exynosdrm]) exynos-dp 145b0000.dp-controller: no DP phy configured exynos-drm exynos-drm: failed to bind 145b0000.dp-controller (ops exynos_dp_ops [exynosdrm]): -517 exynos-drm exynos-drm: master bind failed: -517 ...

vswing/pre-emphasis adjustment calculation is needed in processing of auto phy compliance request other than link training, so have made non-static function. No functional change. v1: initial patch. v2: - used "intel_dp" prefix in function name. (Jani) - used array notation instead pointer for link_status.

During phy compliance auto test mode source need to read requested test pattern from sink through DPCD. After processing the request source need to set the pattern. So set/get method added in drm layer as it is DP protocol. v2: As per review feedback from Manasi on RFC version, - added dp revision as function argument in set_phy_pattern api. - used int for link_rate and u8 for lane_count to align with existing code. v3: As per review feedback from Harry, - used sizeof() instead of magic number. - corrected kernel-doc for drm_dp_phy_test_params structure.
