Add a gpio_chip driver to support the Qualcomm SPMI PMIC
architecture called QPNP. The driver supports Device Tree
and allows a device_node to be registered as a gpio-controller.
The driver also specifies APIs to allow a non-Device Tree user
the ability to configure the PMIC GPIOs.
This driver does not handle interrupts for GPIOs directly.
Instead, that work is handled by the existing qpnp-int driver.
This is feasible since the interrupt register map for all
QPNP peripherals is the same.

Normally bad block counts for ECC stats are collected during boot time.
This can be done lazily when the ECCGETSTATS ioctl is invoked on the
partition. This can significantly decrease boot time, depending on the
size of the partition. Also rescanning on every ioctl invocation helps
in having the latest bad block count rather than depending on the count
that is collected during boot.

This driver is based of the TZCOM (planned to be deprecated soon).
It shares the same design as TZCOM with some re-organization and
new features added. QSEEcom (Qualcomm Secure Execution environment
Communicator) is named accordingly to be consistent with the
nomenclature used in the secure domain. The following additional
features (on top of current TZCOM) driver are implemented:
(1) Add support for multi-image loading.
The image that was loaded in TZCOM was hard-coded to "tzapps".
During a open() tzapps was loaded using pil driver call pil_get().
This severly limted the number of images that could be loaded to
one single application: named "tzapps". qseecom driver provides a
way to load any image on request. Client simply send the image
data in a specific format and this data is sent over to QSEE
(Qualcomm Secure Execution enviroment) to load accordingly.
(2) Add support for multi-client.
TZcom driver did not have provisions to support multiple clients
to interface with the single tzapp image loaded on the secure
domain. The changes added in qseecom driver allows for multiple
client to interface with a single image laoded and running in
secure domain.
(3) Add support for performance tweaking in QSEE
Added capability to send requests to QSEE to set specific clocks
for optimal crypto performance. This essentially will increase
the crypto performance on the secure domain. The crypto
functionality is used extensively by the current existing qseecom
client(s).
(4) Retain legacy support for QSEOS version 1.3.
In order for the existing applications to work with old QSEE image,
qseecom also supports the old mechanism (loading tzapp image via
pil). This was a requirement for existing products that are not
yet using the latest secure code.

Qualcomm PM8058 chip has 8 channels of PWM, also called LPG (Light
Pulse Generator). All PWM channels can be used as simple PWM machine
or as a more advanced PWM pattern generator using programmed lookup
table. This patch supports simple PWM machine as a sub device of
pmic8058 core.
To use PWM:
1. #include <linux/pwm.h>
2. #include <linux/pmic8058-pwm.h> only when you want to do the
configuration by yourself.
3. First call
* pwm_request() -- to reserve a PWM chanel
4. Call these APIs to configure & start/stop a PWM waveform
* pwm_config(period, duty) -- to configure a PWM wave
* pwm_enable() -- to start and enable the PWM output
* pwm_disable() -- to stop and disable the PWM output
You can repeat above 3 calls for different PWM waveforms.
5. Last call
* pwm_free() -- to free the PWM channel

The current core assumes TABLA as the only codec driver registering.
To support single binary for multiple targets its essential that
we remove this restriction and move to a generic framework
to support multiple codec. This can be done by moving all codec
specific code to dedicated codec driver and use core driver to probe
the codec based on slimbus device id and do generic setup for the
codec. This also helps to have same boards with different flavours
of codec variants.
The WCD9XXX family of codecs share the initial codec register
mapping which holds the Slimbus device id to identify the
codec existing on the target.Core driver now registers the
codec device based on this check.
