From: Arnd Bergmann <arnd@xxxxxxxx> [ Upstream commit f5f6e01f9164040ba120f30522efdb4deceb529a ] Compile-testing the DRM_MEDIATEK_HDMI driver shows two missing dependencies, one results in a link failure: arm-linux-gnueabi-ld: drivers/phy/mediatek/phy-mtk-hdmi.o: in function `mtk_hdmi_phy_probe': phy-mtk-hdmi.c:(.text+0xd8): undefined reference to `__clk_get_name' arm-linux-gnueabi-ld: phy-mtk-hdmi.c:(.text+0x12c): undefined reference to `devm_clk_register' arm-linux-gnueabi-ld: phy-mtk-hdmi.c:(.text+0x250): undefined reference to `of_clk_add_provider' arm-linux-gnueabi-ld: phy-mtk-hdmi.c:(.text+0x298): undefined reference to `of_clk_src_simple_get' The other one is a harmless warning: WARNING: unmet direct dependencies detected for PHY_MTK_HDMI Depends on [n]: ARCH_MEDIATEK [=n] && OF [=y] Selected by [y]: - DRM_MEDIATEK_HDMI [=y] && HAS_IOMEM [=y] && DRM_MEDIATEK [=y] Fix these by adding dependencies on CONFIG_OF and CONFIG_COMMON_CLK. With that done, there is also no reason against adding CONFIG_COMPILE_TEST.
