Add device tree binding documentation for On Semiconductor NCP5623 I2C
LED driver. The driver can independently control the PWM of the 3
channels with 32 levels of intensity.
The current delivered by the current source can also be controlled. To
do so, the led-max-microamp property is used by each
Hello,
This series add a new driver for On Semiconductor NCP5623, a 3-channel I2C
LED driver. It is used in our design to drive a RGB LED.
The first patch introduces the device tree binding, while the second patch
adds the driver itself.
Best regards,

The NCP5623 is a 3-channel LED driver from On Semiconductor controlled
through I2C. The PWM of each channel can be independently set with 32
distinct levels. In addition, the intensity of the current source can be
globally set using an external bias resistor fixing the reference
current (Iref) and

In previous version, cpu_pm_enter is invoked after the governor

is included in the idle time. Moving it before the state selection.
Please refer to bellowing chart for detailed information

Hi all,
This is a follow up to the 2 patches to add support for ANX7688 sent here:
https://patchwork.kernel.org/patch/9187809/, thanks Archit and Philipp for
the comments.
I also added 2 patches to add support for a simple display MUX, as I'm facing
similar issues while trying to implement it, i.
ANX7688 is a HDMI to DP converter (as well as USB-C port controller),
that has an internal microcontroller.
The only reason a Linux kernel driver is necessary is to reject
resolutions that require more bandwidth than what is available on
the DP side. DP bandwidth and lane count are reported by the

The Inter-VM communication (IVC) is a communication protocol, which is
designed for interprocessor communication (IPC) or the communication
between the hypervisor and the virtual machine with a guest OS on it. So
it can be translated as inter-virtual memory or inter-virtual machine
communication. T

The Tegra186 has a combination of Denver and Cortex-A57 CPU cores and
GPUs with Pascal architecture on it. It features with ADSP with
Cortex-A9 CPU for audio processing, hardware video encoder/decoder with
multi-format support, ISP for image capture processing and BPMP for the
power managements.

ARM SMCCC is only set for ARMv7 and ARMv8 CPUs, but we currently

well, which results in a link failure:
