Merge tag 'at91-3.5-cleanup' of git://github.com/at91linux/linux-at91 into next/cleanup
Nicolas Ferre <nicolas.ferre@atmel.com> writes: First batch of AT91 cleanup for 3.5 kernel. - The biggest improvement of this series is the ability to compile several AT91 SoCs in one kernel image. For now on it's limited to the DT-enabled boards but we can compile all the core together. - The Kconfig series is stacked before other patches as it is simple and non-intrusive. Its goal is to remove too restrictive dependencies on SoC names. This will allow to add support for newer SoC seamlessly. - Some very "cosmetic" Kconfig changes are also added (entry names, comments, etc.). * tag 'at91-3.5-cleanup' of git://github.com/at91linux/linux-at91: (19 commits) ARM: at91: add defconfig for device tree ARM: at91/dt: do not specify the board any more ARN: at91: introduce SOC_AT91xxx define to allow to compile SoC core support ARM: at91: add SOC_AT91SAM9 kconfig option to factorise select ARM: at91: pm select memory controler at runtime ARM: at91: move at91_init_leds to board init ARM: at91: do not pin mux the UARTs in init_early ARM: at91: drop at91_set_serial_console ARM: at91: uncompress: autodetect the uart to use ARM: at91: uncompress Store UART address in a variable hwrng: Kconfig: remove dependency for atmel-rng driver Input: Kconfig: remove dependency for atmel_tsadcc driver rtc: Kconfig: remove dependency for AT91 rtc driver ARM: at91/Kconfig: website link for AT91SAM9G20-EK ARM: at91/Kconfig: add AT91SAM9x5 family to AT91_EARLY_DBGU0 entry ARM: at91/Kconfig: add clarifications to AT91SAM9M10G45-EK entry ARM: at91/Kconfig: add comment to at91sam9x5 family entry ARM: at91/Kconfig: change at91sam9g45 entry ARM: at91: change AT91 Kconfig entry comment Also updates the cleanup branch to v3.4-rc3.
