Quoting Arnd:
I was thinking the opposite approach and basically removing all uses

We initiate dwc2 usb controller in BIOS, when kernel driver
start-up we should reset AHB hclk domain to reset all AHB

Hello all,
This is version 2 of a patch series to introduce runtime pm in the imx serial
driver. The difference now is that it is rebased on top of linux-next, given
that some of the work done in v1 was already sent.
Here is the link of v1:

This change is a code reorganization. Here we introduce
serial_imx_enable_wakeup() helper function to do
the job of configuring and preparing wakeup sources
on imx serial device. The idea is to allow other
parts of the code to call this function whenever

This change teaches the imx serial driver to save its
context and restore it across suspend and resume path.
To do so, it introduces serial_imx_restore_context()
and serial_imx_save_context() functions. They use
a shadow set of registers to save key registers
and restore them accordingly. These fun
This change introduces pm_qos requests in the imx serial driver.
The idea is to skip deeper C-state in case we need a strict
latency requirement in the uart port. The latency is
computed based on the buffer size and the current baud rate.
We schedule a work queue to set the pm qos requirement.

Systems which have all nodes at a distance of at most
1 hop should be identified as 'NUMA_DIRECT'.
However, the scheduler incorrectly identifies it as
'NUMA_BACKPLANE'. This is because 'n' is assigned to
sched_max_numa_distance but the code (mis)interprets it
to mean 'number of hops'.

Change from v1: Drop PHY binding part, use fwnode_property* APIs.
The first patch (1/2) rearranges the existing code a little with no
functional change to get ready for the second. The second (2/2) does
the actual work of adding support to extract the needed information
from
From: William Cohen
The trampoline code is used by kretprobes to capture a return from a probed
function. This is done by saving the registers, calling the handler, and
restoring the registers. The code then returns to the original saved caller
return address. It is necessary to do this direct
From: Sandeepa Prabhu
The pre-handler of this special 'trampoline' kprobe executes the return
probe handler functions and restores original return address in ELR_EL1.
This way the saved pt_regs still hold the original register context to be
carried back to the probed kernel function.

Kprobes needs simulation of instructions that cannot be stepped
from different memory location, e.g.: those instructions
that uses PC-relative addressing. In simulation, the behaviour
of the instruction is implemented using a copy of pt_regs.
Following instruction catagorie

Add support for basic kernel probes(kprobes) and jump probes
(jprobes) for ARM64.
Kprobes utilizes software breakpoint and single step debug
exceptions supported on ARM v8.
A software breakpoint is placed at the probe address to trap the
kernel execution into the kprobe ha

Certain instructions are hard to execute correctly out-of-line (as in
kprobes). Test functions are added to insn.[hc] to identify these. The
instructions include any that use PC-relative addressing, change the PC,
or change interrupt masking. For efficiency and simplicity

This patchset is heavily based on Sandeepa Prabhu's ARM v8 kprobes patches,
first seen in October 2013. This version attempts to address concerns raised by
reviewers and also fixes problems discovered during testing.
This patchset adds support for kernel probes(kprobes), ju
