Subject: [PATCH v5 10/20] drm/bridge: analogix_dp: support to get &analogix_dp_device.plat_data and &analogix_dp_device.aux
Date: Thu,  9 Jan 2025 11:27:15 +0800	[thread overview]
Message-ID: <20250109032725.1102465-11-damon.ding@rock-chips.com> (raw)
In-Reply-To: <20250109032725.1102465-1-damon.ding@rock-chips.com>

Add two new functions: one to find &analogix_dp_device.plat_data via
&drm_dp_aux, and the other to get &analogix_dp_device.aux. Both of them
serve for the function of getting panel from DP AUX bus, which is why
they are included in a single commit.
