Date: Tue, 7 Jul 2020 17:22:26 +0800 From: Tiezhu Yang <yangtiezhu@...ngson.cn> To: Vinod Koul <vkoul@...nel.org>, Kishon Vijay Abraham I <kishon@...com>, Heiko Stuebner <heiko@...ech.de> Cc: linux-kernel@...r.kernel.org, kernel test robot <lkp@...el.com> Subject: [PATCH] phy: allwinner: Make PHY_SUN6I_MIPI_DPHY depend on COMMON_CLK When CONFIG_ARCH_SUNXI is not set but CONFIG_COMPILE_TEST=y, CONFIG_HAVE_CLK=y, CONFIG_HAVE_LEGACY_CLK=y, there exists the following build errors with CONFIG_PHY_SUN6I_MIPI_DPHY=y: drivers/phy/allwinner/phy-sun6i-mipi-dphy.o: In function `sun6i_dphy_init': phy-sun6i-mipi-dphy.c:(.text+0x320): undefined reference to `clk_set_rate_exclusive' drivers/phy/allwinner/phy-sun6i-mipi-dphy.o: In function `sun6i_dphy_exit': phy-sun6i-mipi-dphy.c:(.text+0x2c8): undefined reference to `clk_rate_exclusive_put' clk_set_rate_exclusive() and clk_rate_exclusive_put() are defined in drivers/clk/clk.c, this file is built under CONFIG_COMMON_CLK, so in order to build drivers/phy/allwinner/phy-sun6i-mipi-dphy.c successful used with various configs, CONFIG_PHY_SUN6I_MIPI_DPHY should depend on CONFIG_COMMON_CLK.
