From 75fabc3f64489aa2c52eec54cd433ea269a25e05 Mon Sep 17 00:00:00 2001 From: Simon Arlott Date: Mon, 10 Sep 2012 23:26:15 -0600 Subject: 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.
