If anyone has any objections, please let me know. ------------------ From: Baoquan He [ Upstream commit e7dd44f4f3166db45248414f5df8f615392de47a ] On s390 systems (aka mainframes), it has classic channel devices for networking and permanent storage that are currently even more common than PCI devices. Hence it could have a fully functional s390 kernel with CONFIG_PCI=n, then the relevant iomem mapping functions [including ioremap(), devm_ioremap(), etc.] are not available. Here let COMMON_CLK_FIXED_MMIO depend on HAS_IOMEM so that it won't be built to cause below compiling error if PCI is unset: ------ ld: drivers/clk/clk-fixed-mmio.o: in function `fixed_mmio_clk_setup': clk-fixed-mmio.c:(.text+0x5e): undefined reference to `of_iomap' ld: clk-fixed-mmio.c:(.text+0xba): undefined reference to `iounmap' ------ Reported-by: kernel test robot Closes: https://lore.kernel.org/oe-kbuild-all/202306211329.ticOJCSv-lkp@intel.com/ Signed-off-by: Baoquan He Cc: Michael Turquette Cc: Stephen Boyd Cc: linux-clk@vger.kernel.org Link: https://lore.kernel.org/r/20230707135852.24292-8-bhe@redhat.com Signed-off-by: Stephen Boyd Signed-off-by: Sasha Levin --- drivers/clk/Kconfig | 1 + 1 file changed, 1 insertion(+) diff --git a/drivers/clk/Kconfig b/drivers/clk/Kconfig index cc871ae3a1792..5b34dbc830ee4 100644 --- a/drivers/clk/Kconfig +++ b/drivers/clk/Kconfig @@ -302,6 +302,7 @@ config COMMON_CLK_BD718XX config COMMON_CLK_FIXED_MMIO bool "Clock driver for Memory Mapped Fixed values" depends on COMMON_CLK && OF + depends on HAS_IOMEM help Support for Memory Mapped IO Fixed clocks -- 2.40.1
