Brian Masney 88c1e9404f soc: qcom: add OCMEM driver
The OCMEM driver handles allocation and configuration of the On Chip
MEMory that is present on some Snapdragon SoCs. Devices which have
OCMEM do not have GMEM inside the GPU core, so the GPU must instead
use OCMEM to be functional. Since the GPU is currently the only OCMEM
user with an upstream driver, this is just a minimal implementation
sufficient for statically allocating to the GPU it's chunk of OCMEM.

This driver currently does not read the gmu-sram node that is described
in the device tree bindings. The starting memory address of the GPU's
reserved memory region is hardcoded to zero to match what the hardware
expects. The driver can be updated to read the reserved memory regions
from device tree once other users of OCMEM are added upstream.

Bjorn Andersson 2209481409 soc: qcom: Add AOSS QMP driver
The Always On Subsystem (AOSS) Qualcomm Messaging Protocol (QMP) driver
is used to communicate with the AOSS for certain side-channel requests,
that are not available through the RPMh interface.

The communication is a very simple synchronous mechanism of messages
being written in message RAM and a doorbell in the AOSS is rung. As the
AOSS has processed the message length is cleared and an interrupt is
fired by the AOSS as acknowledgment.

The driver exposes the QDSS clock as a clock and the low-power state
associated with the remoteprocs in the system as a set of power-domains.

Rajendra Nayak 279b7e8a62 soc: qcom: rpmhpd: Add RPMh power domain driver
The RPMh power domain driver aggregates the corner votes from various
consumers for the ARC resources and communicates it to RPMh.

With RPMh we use 2 different numbering space for corners, one used
by the clients to express their performance needs, and another used
to communicate to RPMh hardware.

The clients express their performance requirements using a sparse
numbering space which are mapped to meaningful levels like RET, SVS,
NOMINAL, TURBO etc which then get mapped to another number space
between 0 and 15 which is communicated to RPMh. The sparse number space,
also referred to as vlvl is mapped to the continuous number space of 0
to 15, also referred to as hlvl, using command DB.

Some power domain clients could request a performance state only while
the CPU is active, while some others could request for a certain
performance state all the time regardless of the state of the CPU.
We handle this by internally aggregating the votes from both type of
clients and then send the aggregated votes to RPMh.

There are also 3 different types of votes that are comunicated to RPMh
for every resource.
1. ACTIVE_ONLY:
	This specifies the requirement for the resource when the CPU is
 	active
2. SLEEP:
	This specifies the requirement for the resource when the CPU is
	going to sleep
3. WAKE_ONLY:
	This specifies the requirement for the resource when the CPU is
	coming out of sleep to active state

We add data for all power domains on sdm845 SoC as part of the patch.
The driver can be extended to support other SoCs which support RPMh

Lina Iyer 658628e7ef drivers: qcom: rpmh-rsc: add RPMH controller for QCOM SoCs
Add controller driver for QCOM SoCs that have hardware based shared
resource management. The hardware IP known as RSC (Resource State
Coordinator) houses multiple Direct Resource Voter (DRV) for different
execution levels. A DRV is a unique voter on the state of a shared
resource. A Trigger Control Set (TCS) is a bunch of slots that can house
multiple resource state requests, that when triggered will issue those
requests through an internal bus to the Resource Power Manager Hardened
(RPMH) blocks. These hardware blocks are capable of adjusting clocks,
voltages, etc. The resource state request from a DRV are aggregated
along with state requests from other processors in the SoC and the
aggregate value is applied on the resource.

Some important aspects of the RPMH communication -
- Requests are <addr, value> with some header information
- Multiple requests (upto 16) may be sent through a TCS, at a time
- Requests in a TCS are sent in sequence
- Requests may be fire-n-forget or completion (response expected)
- Multiple TCS from the same DRV may be triggered simultaneously
- Cannot send a request if another request for the same addr is in
  progress from the same DRV
- When all the requests from a TCS are complete, an IRQ is raised
- The IRQ handler needs to clear the TCS before it is available for
  reuse
- TCS configuration is specific to a DRV
- Platform drivers may use DRV from different RSCs to make requests

Resource state requests made when CPUs are active are called 'active'
state requests. Requests made when all the CPUs are powered down (idle
state) are called 'sleep' state requests. They are matched by a
corresponding 'wake' state requests which puts the resources back in to
previously requested active state before resuming any CPU. TCSes are
dedicated for each type of requests. Active mode TCSes (AMC) are used to
send requests immediately to the resource, while control TCS are used to
provide specific information to the controller. Sleep and Wake TCS send
sleep and wake requests, after and before the system halt respectively.

Rishabh Bhatnagar a3134fb09e drivers: soc: Add LLCC driver
LLCC (Last Level Cache Controller) provides additional cache memory
in the system. LLCC is partitioned into multiple slices and each
slice gets its own priority, size, ID and other config parameters.
LLCC driver programs these parameters for each slice. Clients that
are assigned to use LLCC need to get information such size & ID of the
slice they get and activate or deactivate the slice as needed. LLCC driver
provides API for the clients to perform these operations.

Arnd Bergmann d9d6888feb ARM: qcom: select ARM_CPU_SUSPEND for power management
The qcom spm driver uses cpu_resume_arm(), which is not included
in the kernel in all configurations:

drivers/built-in.o: In function `qcom_cpu_spc':
:(.text+0xbc022): undefined reference to `cpu_suspend'
drivers/built-in.o: In function `qcom_cpuidle_init':
:(.init.text+0x610c): undefined reference to `cpu_resume_arm'

This adds a 'select' Kconfig statement to ensure it's always
enabled.

Arnd Bergmann 10475d592b soc: qcom: enable smsm/smp2p modular build
The newly added smp2p and smsm drivers cannot be loadable modules
but depend on smem, which can be, and that causes a link error:

drivers/built-in.o: In function `qcom_smp2p_intr':
:(.text+0xa6e68): undefined reference to `qcom_smem_get'
drivers/built-in.o: In function `qcom_smp2p_probe':
:(.text+0xa7320): undefined reference to `qcom_smem_alloc'
:(.text+0xa736c): undefined reference to `qcom_smem_get'
drivers/built-in.o: In function `qcom_smsm_probe':
:(.text+0xa7b34): undefined reference to `qcom_smem_get'

This marks all the drivers as 'tristate' to make the Kconfig
dependency resolution work properly.

When I make nconfig, having the SMEM option after the SMD option
causes the configurator to get confused when I'm enabling and
disabling these options. Let's move SMEM before SMD so there's a
clear indented dependency chain.
