ARM: bcm2835: add stub clock driver
This patch adds a minimal stub clock driver for the BCM2835. Its sole purpose is to allow the PL011 AMBA clk_get() API calls to provide something that looks enough like a clock that the driver probes and operates correctly. This patch was extracted from git://github.com/lp0/linux.git branch rpi-split as of 2012/09/08, and modified as follows: * Reworked to call clk_register_fixed_rate(), and clk_register_clkdev() rather than using static data to represent the clocks. * Moved implementation to drivers/clk/. * Modified .dev_id for UART clocks to match UART DT node names. * s/bcm2708/bcm2835/. * Modified device tree vendor prefix.
