That should +be quite reasonable because the reset controller is tightly embedded +inside and exported from these clock subsystems. At least it can be found +on infracfg and pericfg subsystem that both are really fundamental block +lots of devices must depend on. + +commit 74cb0d6dde8 ("clk: mediatek: fixup test-building of MediaTek clock +drivers") can let the build system looking into the directory where the +clock drivers resides and then allow test-building the drivers. + +But the change also gives rise to certain incorrect behavior which is +reset.c being built even not depending on either COMPILE_TEST or +ARCH_MEDIATEK alternative dependency. To get rid of reset.c being built +unexpectedly on the other platforms, it would be a good change that the +file should be built depending on its own specific configuration rather +than just on generic RESET_CONTROLLER one. + +Signed-off-by: Sean Wang <sean.wang@mediatek.com> +Cc: Jean Delvare <jdelvare@suse.de> +Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> +--- + drivers/clk/mediatek/Kconfig | 1 + + drivers/clk/mediatek/Makefile | 4 ++-- + drivers/clk/mediatek/clk-mtk.h | 7 ------- + 3 files changed, 3 insertions(+), 9 deletions(-) + +Index: linux-4.14.25/drivers/clk/mediatek/Kconfig +=================================================================== +--- linux-4.14.25.orig/drivers/clk/mediatek/Kconfig ++++ linux-4.14.25/drivers/clk/mediatek/Kconfig +@@ -6,6 +6,7 @@ menu "Clock driver for MediaTek SoC" + + config COMMON_CLK_MEDIATEK + bool ++ select RESET_CONTROLLER + ---help--- + MediaTek SoCs' clock support. + +Index: linux-4.14.25/drivers/clk/mediatek/Makefile +=================================================================== +--- linux-4.14.25.orig/drivers/clk/mediatek/Makefile ++++ linux-4.14.25/drivers/clk/mediatek/Makefile +@@ -1,6 +1,5 @@ + # SPDX-License-Identifier: GPL-2.0 +-obj-$(CONFIG_COMMON_CLK_MEDIATEK) += clk-mtk.o clk-pll.o clk-gate.o clk-apmixed.o clk-cpumux.o +-obj-$(CONFIG_RESET_CONTROLLER) += reset.o ++obj-$(CONFIG_COMMON_CLK_MEDIATEK) += clk-mtk.o clk-pll.o clk-gate.o clk-apmixed.o clk-cpumux.o reset.o + obj-$(CONFIG_COMMON_CLK_MT6797) += clk-mt6797.o + obj-$(CONFIG_COMMON_CLK_MT6797_IMGSYS) += clk-mt6797-img.o + obj-$(CONFIG_COMMON_CLK_MT6797_MMSYS) += clk-mt6797-mm.o +Index: linux-4.14.25/drivers/clk/mediatek/clk-mtk.h +=================================================================== +--- linux-4.14.25.orig/drivers/clk/mediatek/clk-mtk.h ++++ linux-4.14.25/drivers/clk/mediatek/clk-mtk.h +@@ -229,14 +229,7 @@ void mtk_clk_register_plls(struct device + struct clk *mtk_clk_register_ref2usb_tx(const char *name, + const char *parent_name, void __iomem *reg); + +-#ifdef CONFIG_RESET_CONTROLLER + void mtk_register_reset_controller(struct device_node *np, + unsigned int num_regs, int regofs); +-#else +-static inline void mtk_register_reset_controller(struct device_node *np, +- unsigned int num_regs, int regofs) +-{ +-} +-#endif + + #endif /* __DRV_CLK_MTK_H */ |
