V2:
* dropped "net: davicom: dm9000: allow to pass MAC address through mac_addr module parameter"
  from this series because it goes through the netdev tree
  (suggested by Andrew Lunn <andrew@lunn.ch>)
* added a "fixes:" for "MIPS: DTS: CI20: fix PMU definitions for ACT8600"
  and "MIPS: DTS: CI20: fix interrupt for pcf8563 RTC"
  (suggested by Andreas Kemnade <andreas@kemnade.info>)
* "i2c: jz4780: silence log flood on txabrt" dropped because it is
  replaced by a new version in v5.6 by Wolfram Sang <wsa@the-dreams.de>

PATCH V1 2020-02-11 22:41:43:
This patch set provides several improvements for the CI20 board:

* suppress warnings from i2c if device is not responding
* make ingenic-drm found through DT
* allow davicom dm9000 ethernet controller to use MAC address provided by U-Boot
* fix #include in jz4780.dtsi
* configure for loadable kernel modules
* add DTS for IR sensor and SW1 button
* configure so that LEDs, IR sensor, SW1 button have drivers
* fix DTS for ACT8600 PMU and configure driver
* fix interrupt of nxp,pcf8563

There is another patch set in our queue to add HDMI support on top of this work.

Add MODULE_DEVICE_TABLE so that the driver can load by
matching the device tree if compiled as module.

The constants from irq.h and gpio.h can be used in the
jz4780.dtsi and derived DTS like ci20.dts.

Not all drivers need to be compiled into the kernel.
Support building and loading of kernel modules.

DTS has been augmented to add some gpio-leds. We need the leds-gpio driver
and enable the triggers.

There is a ACT8600 on the CI20 board and the bindings of the
ACT8865 driver have changed without updating the CI20 device
tree. Therefore the PMU can not be probed successfully and
is running in power-on reset state.

Fix DT to match the latest act8865-regulator bindings.

The PMU on the CI20 board is an ACT8600 using the ACT8865 driver.
Since it is not compiled, the PMU and the CI20 board is running in
power-on reset state of the PMU.

From: Alex Smith <alex.smith@imgtec.com>

The infrared sensor on the CI20 board is connected to a GPIO and can
be operated by using the gpio-ir-recv driver. Add a DT node for the
sensor to allow that driver to be used.

The SW1 button can be used as a simple one-button keyboard
and is connected to PD17.

Note: SW1 has a second meaning to change the boot sequence
when pressed while powering on.

Interrupts should not be specified by interrupt line but by
gpio parent and reference.

Hi Nikolaus,

Please rebase this patch on top of drm-misc-next and send it apart - it 
should go through the DRM tree.

Hi Nikolaus,

Patches 03-12 only touch the same two files - ci20.dts and 
ci20_defconfig.

Unless someone strongly disagrees, I'd suggest to squash all patches 
that touch each file together (except the ones with a Fixes tag), I 
don't think we really need that much granularity here.

If you add a Fixes tag, you should also add:
Cc: stable@vger.kernel.org

if you're fixing something older than -rc1, which is the case here 
(alternatively Cc them manually, but just for these patches).

Same remark for your patch 05/12.

Cheers,

It comes more from having developed these things quite independently and only collected for submission...

One patch I don't know how to handle: "MIPS: DTS: CI20: add DT node for IR sensor".
It is from 2015 and has a different author (some Alex Smith but the mail address seems to be broken).
This information and attribution will be lost if we squash them.

But I can do for V3 and will also fix the fixes tags by adding cc: stable :)

BR and thanks,
Nikolaus
