Intel Moorestown platform support was removed few years ago. This is a follow up which removes Moorestown specific code for the serial devices. It includes mrst_max3110 and earlyprintk bits. This was used on SFI (Medfield, Clovertrail) based platforms as well, though new ones use normal serial interface for the console service.

由 Pankaj Dubey 提交于
Exynos7 has a similar serial controller to that present in older Samsung SoCs. To re-use the existing serial driver on Exynos7 we need to have SERIAL_SAMSUNG_UARTS_4 and SERIAL_SAMSUNG_UARTS selected. This is not possible because these symbols are dependent on PLAT_SAMSUNG which is not present for the ARMv8 based exynos7. Change the dependency of these symbols from PLAT_SAMSUNG to the serial driver thus making it available on exynos7. As the existing platform specific code making use of these symbols is related to uart driver this change in dependency should not cause any issues.

This device was originally supported on bcm63xx only, but it shows up on a wide variety of MIPS and ARM chipsets spanning multiple product lines. Now that the driver has eliminated dependencies on bcm63xx-specific header files, we can build it on any non-bcm63xx kernel. Compile-tested on x86, both statically and as a module.

CLPS711X serial driver uses the system wide registers to control the modem signals. Now gpio-syscon driver can be used for this purposes. mctrl_gpio helpers allow us to create GPIO bindings for any of modem/tty control signals that extends the functionality of the driver.

Two new drivers have been added since 3.14, the MEN 16z135 uart, and the ARM semihosting console. Both are missing an explicit 'select SERIAL_CORE', which can leads build errors when no other driver selects the core, as found during ARM randconfig testing. In case of the ARM semihosting console, we also have to select SERIAL_CORE_CONSOLE. This adds the missing 'select' statements.
