Add a kernel interface to limit GPU power level during
high-risk low voltage or high current conditions of the
battery.
kgsl_pwr_limits_add is called by every client to add a node
to the limits list. The client can then call other APIs such as
kgsl_pwr_limits_set_freq or kgsl_pwr_limits_set_default to set limits.
Once the client is done with limits it should delete the limits node
by calling kgsl_pwr_limits_del.
Limits can be set from both kernel APIs and sysfs nodes.
Make sure all votes are considered before setting the final limits.

System should not enter global low power modes during GPU wakeup.
To avoid this problem, explicitly vote against these modes at the
beginning of wakeup, and restore the vote to the default value
after that.

io_fraction was originally used as a way to influence the CPU
frequency governor. Due to governor updates and timing changes
no targets use io_fraction now and there is no plan to do so in
the future.

Do not share IOMMU internal data stuctures with rest of the world,
iommu context id's are internal to gpu iommu driver restrict them
to internal header files.

Remove pm_qos_latency from the legacy pdata struct and read it
directly from the device tree in kgsl_pwrctrl_init().

The oxili_rbbmtimer_clk needs to be enabled to take advantage of
the RBBM_ALWAYSON_COUNTER. Add this clk to this list of gpu clks
being enabled.

Currently a fixed number of BIMC votes are required per GPU
frequency. Read the enumerated votes directly from the bus
table and set min/max limits on the votes dynamically.

pm_qos_latency parameter can be configured from
device tree as well. Will set to default value if
entry not found in target device tree.

No platforms with direct ebi1 connections exist, nor
is idling before changing the frequency needed.

to determine the requested bus bandwidth vote at a given

We already have another header - msm_kgsl.h in include/linux.

The pdata structure and associated structs have no business being
in msm_kgsl.h. Move them to include/mach/kgsl.h where they can
thrive in a non-userspace facing environment.
