[PATCH v5 00/10] arm: dts: extend mt7623 support

[sean.wang]

From: Sean Wang <sean.wang@mediatek.com>

Change since v4:
- split mt6323 nodes as the independent item which tends to integration with
  other MediaTek SoCs
- enhanced commit log
- fixed up building warning shown in make dtsb
- added clock-frequency to CPU nodes to avoid warning in boot time
- added more nodes into the SoC-level file mt7623.dtsi such as CPU OPP table
  and thermal zone treating CPU as one of cooling devices
- cleaned up the file mt7623n-bananapi-bpi-r2.dts such as listing nodes in
  alphabetical order

Changes since v3:
- explain in the commit message why this binding is changed
- patches for dt-binding is reordered at the beginning of patch list
- be concise wigh using SPDX-License-Identifier in new dts file

Changes since v2:
- exclude those patch are already queued into v4.11-next/dts32
- exclude those patches already sent in separation
- add mt7623a SoC basic support
- update binding SoC for mt7623n and relevant boards

Changes since v1:
Continue the upstream journey based on the previous John Crispin's good work.
- add fixes for the v1 suggestion
- fix typo in the commit log
- add missing pinctrl bindings for mt7623
- reuse pinctrl driver for mt7623
- enhance existing nodes since the way for binding is changed e.g USB
- add more nodes which already gets support from the latest tree e.g MT7530 DSA
- add the dts file for Bananapi R2 (BPI-R2) board

[PATCH v5 04/10] arm: dts: mt7623: rename mt7623-evb.dts to arch/arm/boot/dts/mt7623n-rfb.dtsi

[sean.wang]

From: Sean Wang <sean.wang@mediatek.com>

There are 2 versions of the MT7623 SoC, the one is MT7623N and the other
is MT7623A.  MT7623N is almost identical to MT7623A but has some
additional multimedia features. The reference boards are available as
NAND or MMC and might have a different ethernet setup. In order to reduce
the duplication of devicetree code we add an intermediate dtsi file for
these reference boards. Additionally MediaTek pointed out, that the EVB
is yet another board and the board in question is infact the RFB. Take
this into account while renaming the files.

[PATCH v5 01/10] dt-bindings: arm: mediatek: update for MT7623n SoC and relevant boards

[sean.wang-NuS5LvNUpcJWk0Htik3J/w]

From: Sean Wang <sean.wang-NuS5LvNUpcJWk0Htik3J/w@public.gmane.org>

Because there are two versions of MT7623 SoC that is MT7623a and MT7623n
respectively. So update the part of MT7623n bindings to allow that people
tend to differentiate which MT7623 SoC the boards applies.

And "mediatek,mt7623-evb" can be safely changed to
"mediatek,mt7623n-rfb-nand" because mt7623-evb is a kind of debug board
internally in Mediatek which real users can't get. So instead we should
indicate which variants it belongs to with more specific postfix as the
adding here to let people easily know what board they use.

[PATCH v5 03/10] arm: dts: mt7623: add mt6323.dtsi file

[sean.wang-NuS5LvNUpcJWk0Htik3J/w]

From: John Crispin <john-Pj+rj9U5foFAfugRpC6u6w@public.gmane.org>

MediaTek produces various PMICs. Which one is used depends on the actual
circuit design. Instead of adding the correct PMIC node to every dts file
we instead add a new intermediate dtsi file which adds the PMIC node. For
those boards with the same PMIC, the intermediate mt6323.dtsi could be
reused to save more redundant nodes created on each board device-tree
files.

Hi, Joe.C

I will have note for this. Those would be fixed up along with following
patches when mt7623a dts is introduced.

[PATCH v5 06/10] arm: dts: mt7623: cleanup the mt7623n rfb uart nodes

[sean.wang-NuS5LvNUpcJWk0Htik3J/w]

From: John Crispin <john-Pj+rj9U5foFAfugRpC6u6w@public.gmane.org>

This patch does a cleanup of the uart nodes in the dts file of the RFB. It
adds aliases, enables 2 more uarts and explicitly sets the uart mode of the
console.

[PATCH v5 07/10] arm: dts: mt7623: enable the usb device on the mt7623n rfb

[sean.wang-NuS5LvNUpcJWk0Htik3J/w]

From: John Crispin <john-Pj+rj9U5foFAfugRpC6u6w@public.gmane.org>

All versions of the mt7623n RFB have an USB port so enable the device.
There is a gpio that gets used to power up the port supply. Add support
for this gpio using the fixed-regulator driver.

[PATCH v5 09/10] arm: dts: mt7623: add support for Bananapi R2 (BPI-R2) board

[sean.wang]

From: Sean Wang <sean.wang@mediatek.com>

Add support for the Bananapi R2 (BPI-R2) development board from
BIPAI KEJI. Detailed hardware information for BPI-R2 which could be
found on http://www.banana-pi.org/r2.html

The patch added nodes into the SoC-level file mt7623.dtsi such as CPU OPP
table and thermal zone treating CPU as one of cooling devices and also
added nodes into board-level file mt7623n-bananapi-bpi-r2.dts such as
MediaTek GMAC, MT7530 Switch, the crypto engine, USB, IR, I2S, I2C, UART,
SPI, PWM, GPIO keys, GPIO LEDs and PMIC LEDs. As to the other missing
hardware and peripherals, they would be added and integrated continuously.

[PATCH v5 10/10] arm: dts: mt7623: add clock-frequency to CPU nodes

[sean.wang]

From: Sean Wang <sean.wang@mediatek.com>

Add clock-frequency property to CPU nodes. Avoids warnings like
[    0.001568] /cpus/cpu@0 missing clock-frequency property
[    0.001588] /cpus/cpu@1 missing clock-frequency property
[    0.001601] /cpus/cpu@2 missing clock-frequency property
[    0.001614] /cpus/cpu@3 missing clock-frequency property
at boot time
