Subject: [v2] gpu: ipu-v3: allow to build with ARCH_LAYERSCAPE
Date:   Fri, 19 Jul 2019 18:17:51 +0800
Message-Id: <20190719101751.12315-1-wen.he_1@nxp.com>
Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

The new LS1028A DP driver code causes a link failure when DRM_IMX built-in,
but platform is ARCH_LAYERSCAPE:

drivers/gpu/drm/imx/ipuv3-crtc.c:51: undefined reference to `ipu_prg_enable'
drivers/gpu/drm/imx/ipuv3-crtc.c:52: undefined reference to `ipu_dc_enable'
drivers/gpu/drm/imx/ipuv3-crtc.c:53: undefined reference to `ipu_dc_enable_channel'
drivers/gpu/drm/imx/ipuv3-crtc.c:54: undefined reference to `ipu_di_enable'
drivers/gpu/drm/imx/ipuv3-crtc.o: In function `ipu_crtc_mode_set_nofb

Adding a Kconfig dependency allow to build if ARCH_LAYERSCAPE is enable.

        - fix Kconfig conflit issue after rebased to kernel 5.2
