Hi Bryan, I love your patch! Yet something to improve: [auto build test ERROR on usb/usb-testing] [also build test ERROR on balbi-usb/testing/next peter.chen-usb/ci-for-usb-next v5.7-rc6 next-20200519] [if your patch is applied to the wrong git tree, please drop us a note to help improve the system. BTW, we also suggest to use '--base' option to specify the base tree in git format-patch, please see https://stackoverflow.com/a/37406982] url: https://github.com/0day-ci/linux/commits/Bryan-O-Donoghue/usb-typec-Ensur... base: https://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git usb-testing config: i386-tinyconfig compiler: gcc-7 (Ubuntu 7.5.0-6ubuntu2) 7.5.0 reproduce: make ARCH=i386 tinyconfig make ARCH=i386 If you fix the issue, kindly add following tag as appropriate Reported-by: kbuild test robot <lkp(a)intel.com&gt; All errors (new ones prefixed by >>, old ones prefixed by <<): drivers/of/Kconfig:69: symbol OF_IRQ depends on IRQ_DOMAIN kernel/irq/Kconfig:68: symbol IRQ_DOMAIN is selected by REGMAP drivers/base/regmap/Kconfig:7: symbol REGMAP default is visible depending on REGMAP_I2C drivers/base/regmap/Kconfig:19: symbol REGMAP_I2C is selected by TYPEC_TPS6598X drivers/usb/typec/Kconfig:64: symbol TYPEC_TPS6598X depends on USB_ROLE_SWITCH drivers/usb/roles/Kconfig:3: symbol USB_ROLE_SWITCH is selected by USB_MUSB_MEDIATEK drivers/usb/musb/Kconfig:119: symbol USB_MUSB_MEDIATEK depends on GENERIC_PHY drivers/phy/Kconfig:8: symbol GENERIC_PHY is selected by PHY_BCM_NS_USB3 drivers/phy/broadcom/Kconfig:41: symbol PHY_BCM_NS_USB3 depends on MDIO_BUS drivers/net/phy/Kconfig:13: symbol MDIO_BUS depends on MDIO_DEVICE drivers/net/phy/Kconfig:6: symbol MDIO_DEVICE is selected by PHYLIB drivers/net/phy/Kconfig:243: symbol PHYLIB is selected by ARC_EMAC_CORE drivers/net/ethernet/arc/Kconfig:19: symbol ARC_EMAC_CORE is selected by ARC_EMAC drivers/net/ethernet/arc/Kconfig:25: symbol ARC_EMAC depends on OF_IRQ For a resolution refer to Documentation/kbuild/kconfig-language.rst subsection "Kconfig recursive dependency limitations" vim +69 drivers/of/Kconfig 5ab5fc7e35705c Grant Likely 2010-07-05 14 19fd74879a32fb Grant Likely 2014-11-04 15 config OF_UNITTEST 19fd74879a32fb Grant Likely 2014-11-04 16 bool "Device Tree runtime unit tests" 6019a3d07d7258 Rob Herring 2017-07-25 17 depends on !SPARC 6019a3d07d7258 Rob Herring 2017-07-25 18 select IRQ_DOMAIN 649e0a77e28a77 Rob Herring 2015-05-28 19 select OF_EARLY_FLATTREE 2eb46da2a760e5 Grant Likely 2014-10-02 20 select OF_RESOLVE 53a42093d96ef5 Grant Likely 2011-12-12 21 help 53a42093d96ef5 Grant Likely 2011-12-12 22 This option builds in test cases for the device tree infrastructure 5d9270869b6cd3 Geert Uytterhoeven 2013-12-24 23 that are executed once at boot time, and the results dumped to the 53a42093d96ef5 Grant Likely 2011-12-12 24 console. 53a42093d96ef5 Grant Likely 2011-12-12 25 53a42093d96ef5 Grant Likely 2011-12-12 26 If unsure, say N here, but this option is safe to enable. 53a42093d96ef5 Grant Likely 2011-12-12 27 1b7c501b51a8c8 Rob Herring 2015-10-06 28 config OF_ALL_DTBS 1b7c501b51a8c8 Rob Herring 2015-10-06 29 bool "Build all Device Tree Blobs" 1b7c501b51a8c8 Rob Herring 2015-10-06 30 depends on COMPILE_TEST 1b7c501b51a8c8 Rob Herring 2015-10-06 31 select DTC 1b7c501b51a8c8 Rob Herring 2015-10-06 32 help 1b7c501b51a8c8 Rob Herring 2015-10-06 33 This option builds all possible Device Tree Blobs (DTBs) for the 1b7c501b51a8c8 Rob Herring 2015-10-06 34 current architecture. 1b7c501b51a8c8 Rob Herring 2015-10-06 35 1b7c501b51a8c8 Rob Herring 2015-10-06 36 If unsure, say N here, but this option is safe to enable. 1b7c501b51a8c8 Rob Herring 2015-10-06 37 e169cfbef46d62 Grant Likely 2009-11-23 38 config OF_FLATTREE e169cfbef46d62 Grant Likely 2009-11-23 39 bool 5ab5fc7e35705c Grant Likely 2010-07-05 40 select DTC e6a6928c3ea1d0 Rob Herring 2014-04-02 41 select LIBFDT 08d53aa58cb162 Ard Biesheuvel 2014-11-14 42 select CRC32 e169cfbef46d62 Grant Likely 2009-11-23 43 e6ce1324e4f08b Stephen Neuendorffer 2010-11-18 44 config OF_EARLY_FLATTREE e6ce1324e4f08b Stephen Neuendorffer 2010-11-18 45 bool ff4c25f26a71b7 Christoph Hellwig 2019-02-03 46 select DMA_DECLARE_COHERENT if HAS_DMA e6ce1324e4f08b Stephen Neuendorffer 2010-11-18 47 select OF_FLATTREE e6ce1324e4f08b Stephen Neuendorffer 2010-11-18 48 3cfc535c5df812 Andres Salomon 2010-10-10 49 config OF_PROMTREE 3cfc535c5df812 Andres Salomon 2010-10-10 50 bool 3cfc535c5df812 Andres Salomon 2010-10-10 51 b56b5528f5b3c3 Rob Herring 2017-10-04 52 config OF_KOBJ b56b5528f5b3c3 Rob Herring 2017-10-04 53 def_bool SYSFS b56b5528f5b3c3 Rob Herring 2017-10-04 54 0f22dd395fc473 Grant Likely 2012-02-15 55 # Hardly any platforms need this.
