This series adds an algorithm for an I2C master physically located on an FSI
slave device. The I2C master has multiple ports, each of which may be connected
to an I2C slave. Access to the I2C master registers is achieved over FSI bus.
Due to the multi-port nature of the I2C master, the driver inst
Since there are many ports per master, each with it's own adapter and
chardev, we need some locking to prevent transfers from changing the
master state while other transfers are in progress.

Following in the footsteps of what was done for filters, adding the
necessary mechanic needed to push down driver specific configuration
to the kernel using an ioctl. By proceeding this way PMU specific
configuration such as CoreSight sink specification can be communicated
to each event.
Signed-of
When pmu::setup_aux() is called the coresight PMU needs to know which
sink to use for the session by looking up the information in the
drv_config field of the hw_perf_event structure.
As such simply replace the cpu information by the complete perf_event
structure and change all affected customers.
Using sysFS to communicate sink information for a trace session doesn't
work when more than one CPU is involved in the scenario. As such
communicate the sink information to each event by using the SET_DRV_CONFIG
ioctl command.

Rename mtk_timer to timer-mediatek to apply new naming convention
in clocksource folder.

Convert the driver to use the timer_of helpers.
This allows to remove custom proprietary structure,
factors out and simplifies the code.

This patch adds a new "System Timer" on the Mediatek SoCs.
The System Timer is introduced as an always-on timer being
clockevent device for tick-broadcasting.
For clock, it is driven by 13 MHz system clock.
The implementation uses the system clock with no clock
source divider.
For interrupt, the
This patch adds bindings of new "System Timer" on Mediatek SoCs.
Remove RTC clock in the same time because it is not used
in both "General Purpose Timer" and "System Timer" driver now.

Arm64's unistd.h simply #includes the asm-generic/unistd.h, so,
since we will want to know whether either change, we grab both:

This should speed up accessing new system calls introduced with the
kernel rather than waiting for libaudit updates to include them.
It also enables users to specify wildcards, for example, perf trace -e
'open*', just like was already possible on x86, s390, and powerpc, which
means arm64 can now p
