drm/rockchip: rgb: update SPDX license identifier Update SPDX License Identifier from GPL-2.0+ to GPL-2.0 and drop some GPL text. This fixes a mismatch between the existing SPDX headers and GPL boilerplate text. Fixes: 1f0f01515172 ("Add support for Rockchip Soc RGB output interface") Cc: stable@vger.kernel.org Reported-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Sandy Huang <hjc@rock-chips.com> Signed-off-by: Heiko Stuebner <heiko@sntech.de> Link: https://patchwork.freedesktop.org/patch/msgid/1548238479-171491-1-git-send-email-hjc@rock-chips.com

drm/rockchip: Add support for Rockchip Soc RGB output interface Some Rockchip CRTCs, like rv1108 and px30, can directly output parallel and serial RGB data to panel or conversion chip. So add a feature-bit for vops to mark the ability for these direct outputs and add an internal encoder in that case, that can attach to bridge chipsor panels. Changes in v7: 1. forget to delete rockchip_rgb_driver and delete it. Changes in v6: 1. Update according to Heiko Stuebner' implemention, rgb output is part of vop's feature, should not register as a independent driver. Changes in v5: 1. add SPDX-License-Identifier tag Changes in v4: 1. add support px30; Changes in v3: 1. update for rgb-mode move to panel node. Changes in v2: 1. add error log when probe failed; 2. update name_to_output_mode() according to sean's suggest; 3. Fix uninitialized use of ret.

drm/rockchip: rgb: add stub functions when rgb encoder is disabled The newly added internal rgb encoder for Rockchip vops is missing stubs for the case that the rgb output part is not enabled in the kernel config. So add these.
