2011-03-08msm: iommu: Rework clock logic and add IOMMU bus clock controlStepan Moskovchenko
Clean up the clock control code in the probe calls, and add support for controlling the clock for the IOMMU bus interconnect. With the (proper) clock driver in place, the clock control logic in the probe function can be made much cleaner since it does not have to deal with the placeholder driver anymore.

2011-03-08msm: iommu: Clock control for the IOMMU driverStepan Moskovchenko
Add clock control to the IOMMU driver. The IOMMU bus clock (and potentially an AXI clock) need to be on to gain access to IOMMU registers. Actively control these clocks when needed instead of leaving them on. Signed-off-by: Stepan Moskovchenko <stepanm@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>
2011-02-28msm: clock: Migrate to clkdevStephen Boyd
Migrating to clkdev has several advantages: * Less code in mach-msm/clock.c * A more robust clk_get() implementation * clk_add_alias() support * clk_get_sys() support In general, this will help board authors setup clock aliases and break the dependency on device pointers in the clock tables.

2011-02-28msm: clock: Remove references to clk_ops_pcomStephen Boyd
Not all devices use proc_comm and determining if a clock is local vs. remote is fragile when done by comparing clk_ops pointers. Instead, implement an is_local() function for all clk_ops to determine if the clock is local. Doing this allows us to remove the last references to clk_ops_pcom from clock.c and compile it for targets with CONFIG_MSM_PROC_COMM=n. We don't need to set the clk_ops at runtime until 7x30 local clock detection comes in. Right now it's just complicating things so just set the ops pointer statically.

2011-01-28msm: clock: Invert debugfs directory layoutStephen Boyd
There are currently 3 separate directories for clock debugging in debugfs: clk_enable, clk_rate, and clk_local. Each of these directories contains a list of clocks. This is rather annoying when you are focusing on one clock and want to enable/disable it and then check its rate. You either have to cd to the other directory or cat ../clk_rate/<clk>. Invert the layout so that there is one clock directory containing a directory for each clock. Inside each respective clock directory place an enable, rate, and is_local file relating to the clk_enable, clk_disable, and clk_local directories that exist today.

2011-01-20kconfig: rename CONFIG_EMBEDDED to CONFIG_EXPERTDavid Rientjes
The meaning of CONFIG_EMBEDDED has long since been obsoleted; the option is used to configure any non-standard kernel with a much larger scope than only small devices. This patch renames the option to CONFIG_EXPERT in init/Kconfig and fixes references to the option throughout the kernel. A new CONFIG_EMBEDDED option is added that automatically selects CONFIG_EXPERT when enabled and can be used in the future to isolate options that should only be considered for embedded systems (RISC architectures, SLOB, etc). Calling the option "EXPERT" more accurately represents its intention: only expert users who understand the impact of the configuration changes they are making should enable it.
