devm_ioremap_resource() will be not built in lib/devres.c if CONFIG_HAS_IOMEM is not set, of_address_to_resource() will be not built in drivers/of/address.c if CONFIG_OF_ADDRESS is not set, and then there exists two build errors about undefined reference to "devm_ioremap_resource" and "of_address_to_resource" in phy-mtk-xsphy.c under COMPILE_TEST and CONFIG_PHY_MTK_XSPHY, make PHY_MTK_XSPHY depend on HAS_IOMEM and OF_ADDRESS to fix it.
The above issue is reported by kernel test robot <l...@intel.com>, through the discussion in the v1 patch, as Chunfeng said we need also do this for config PHY_MTK_TPHY: drivers/phy/mediatek/phy-mtk-tphy.c:1157: retval = of_address_to_resource(child_np, 0, &res); drivers/phy/mediatek/phy-mtk-tphy.c:1123: tphy->sif_base = devm_ioremap_resource(dev, sif_res); drivers/phy/mediatek/phy-mtk-tphy.c:1164: instance->port_base = devm_ioremap_resource(&phy->dev, &res); Reported-by: kernel test robot <l...@intel.com> Signed-off-by: Tiezhu Yang <yangtie...@loongson.cn> Acked-by: Randy Dunlap <rdun...@infradead.org> --- drivers/phy/mediatek/Kconfig | 6 ++++-- 1 file changed, 4 insertions(+), 2 deletions(-) diff --git a/drivers/phy/mediatek/Kconfig b/drivers/phy/mediatek/Kconfig index 50c5e93..f44800b 100644 --- a/drivers/phy/mediatek/Kconfig +++ b/drivers/phy/mediatek/Kconfig @@ -5,7 +5,8 @@ config PHY_MTK_TPHY tristate "MediaTek T-PHY Driver" depends on ARCH_MEDIATEK || COMPILE_TEST - depends on OF + depends on OF && OF_ADDRESS + depends on HAS_IOMEM select GENERIC_PHY help Say 'Y' here to add support for MediaTek T-PHY driver, @@ -29,7 +30,8 @@ config PHY_MTK_UFS config PHY_MTK_XSPHY tristate "MediaTek XS-PHY Driver" depends on ARCH_MEDIATEK || COMPILE_TEST - depends on OF + depends on OF && OF_ADDRESS + depends on HAS_IOMEM select GENERIC_PHY help Enable this to support the SuperSpeedPlus XS-PHY transceiver for -- 2.1.0
