Revert "drm: Switch DRM_DISPLAY_HELPER to depends on"This reverts commit e075e496f516bf92bc0cbaf94d64e8d4a6b58321, as helpercode should always be selected by the driver that needs it, for theconvenience of the final user configuring a kernel.The user who configures a kernel should not need to know which helpersare needed for the driver he is interested in. Making a driver dependon helper code means that the user needs to know which helpers to enablefirst, which is very user-unfriendly.Signed-off-by: Geert Uytterhoeven Acked-by: Arnd Bergmann Link: https://patchwork.freedesktop.org/patch/msgid/1ba76cc4d96a8afefff5d1bc42fb1e1329c5da68.1713780345.git.geert+renesas@glider.beSigned-off-by: Maxime Ripard List of files: /linux-6.15/drivers/gpu/drm/bridge/cadence/Kconfig

drm: Switch DRM_DISPLAY_HDCP_HELPER to depends onMost of our helpers have relied on being selected so far throughKconfig, but that creates issues when we have multiple layers of helperswith some depending on others.Indeed, select doesn't select a dependency's dependencies, and thusisn't super intuitive.

Toavoid naming conflicts, rename drm_dp_helper.c to drm_dp.cThis change can help to reduce the size of the kernel binary.

It integrates uCPU running theembedded Firmware (FW) interfaced over APB interface.Basically, it takes a DPI stream as input and outputs it encoded in DPformat.
