2011-03-10msm: scm: Check for interruption immediatelyStephen Boyd1-24/+27
When we're interrupted on the secure side, we should just issue another smc instruction again instead of replaying the arguments to smc. Fix it. Signed-off-by: Stephen Boyd <sboyd@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>
2011-03-10msm: scm: Fix improper register assignmentStephen Boyd1-2/+5
Assign the registers used in the inline assembly immediately before the inline assembly block. This ensures the compiler doesn't optimize away dead register assignments when it shouldn't.

2011-03-09msm: iommu: Don't read from write-only registersStepan Moskovchenko2-29/+1
Don't read from V2Pxx command registers when doing iova-to-phys operations. These registers are write-only and reading the value before modifying the VA bits is unnecessary. Signed-off-by: Stepan Moskovchenko <stepanm@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>
2011-03-09msm: iommu: Remove dependency on IDRStepan Moskovchenko4-22/+42
Remove the depencency on the IOMMU IDR register, as it may not be accessible depending on the security configuraton. This involves moving the NCB field of IDR into the platform data. Signed-off-by: Stepan Moskovchenko <stepanm@codeaurora.org> Signed-off-by: David Brown <davidb@codeaurora.org>

2011-03-09msm: iommu: Rework clock logic and add IOMMU bus clock controlStepan Moskovchenko3-95/+121
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.

2011-03-09msm: iommu: Clock control for the IOMMU driverStepan Moskovchenko2-5/+62
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 Boyd15-86/+98
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 Boyd7-77/+11
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 Boyd1-25/+23
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.

2011-01-28msm: clock: Move debugfs code from clock.c to clock-debug.cMatt Wagantall4-122/+150
