Is HAVE_CLK not > enough? Nope. E.g. for alpha architecture, HAVE_CLK is not set and without COMMON_CLK: drivers/pwm/pwm-meson.o: In function `meson_pwm_init_channels': (.text+0x244): undefined reference to `devm_clk_register' I guess other solution would be to add stubs for few clk functions... > Also HAS_IOMEM is a typical requirement, but I tested with an ARCH=um > config (which does't have HAS_IOMEM) and they all compile fine. Because of !HAS_IOMEM, since some time ARCH=um does not support COMPILE_TEST. Therefore HAS_IOMEM dependency is not needed for compile testing (and for regular build it is selected by ARCH). > > > @@ -318,7 +319,7 @@ config PWM_MEDIATEK > > > > config PWM_MXS > > tristate "Freescale MXS PWM support" > > - depends on ARCH_MXS && OF > > + depends on (ARCH_MXS && OF) || COMPILE_TEST > > select STMP_DEVICE > > help > > Generic PWM framework driver for Freescale MXS. > > @@ -328,7 +329,8 @@ config PWM_MXS > > > > config PWM_OMAP_DMTIMER > > tristate "OMAP Dual-Mode Timer PWM support" > > - depends on OF && ARCH_OMAP && OMAP_DM_TIMER > > + depends on (ARCH_OMAP && OMAP_DM_TIMER) || COMPILE_TEST > > + depends on OF > > I'm surprised that OF isn't required for PWM_MXS but is is for > PWM_OMAP_DMTIMER. pwm-mxs compiles without CONFIG_OF, didn't test > pwm-omap-dmtimer. Since some time !OF has all necessary stubs so OF is actually needed only for binding, not compiling.
