Message-ID: <6862654.ZzBrnrRESe@wuerfel> Date: Mon, 26 May 2014 17:34:24 +0200 From: Arnd Bergmann <arnd@...db.de> To: linux-arm-kernel@...ts.infradead.org Cc: Pawel Moll <pawel.moll@....com>, Lee Jones <lee.jones@...aro.org>, linux-kernel@...r.kernel.org Subject: [PATCH] ARM: vexpress: refine dependencies for new code The versatile express changes for 3.16 introduced a number of build regressions for randconfig kernels by not tracking dependencies between the components right. This patch tries to rectify that: * the mach-vexpress code cannot link without the syscfg driver, which in turn needs MFD_VEXPRESS_SYSREG * various drivers call devm_regmap_init_vexpress_config(), which has to be exported so it can be used by loadable modules * the configuration bus uses OF DT helper functions that are not available to platforms disable CONFIG_OF * The sysreg driver exports GPIOs through gpiolib, which can be disabled on some platforms. * The clocksource code cannot be built on platforms that don't use modern timekeeping but rely on gettimeoffset.
