This patch serie adds basic support for the MediaTek MT8195
demo board. For now the support is pretty basic and allow
just to boot, use USB, and the SD card.
When more IO support will be added for MT8195, new changes
will be pushed to the device-tree of the MT8195 demo board
to support these IOs as well.
This serie depends on the following patches:

Add basic device-tree for the MT8195 Demo board. The
Demo board is made by MediaTek and has a MT8195 SoC,
associated with the MT6359 and MT6360 PMICs, and
the MT7921 connectivity chip.
The IOs available on that board are:
* 1 USB Type-C connector with DP aux mode support
* 1 USB Type-A connector
* 1 full size HDMI RX and 1 full size HDMI TX connector
* 1 uSD slot
* 40 pins header
* SPI interface header
* 1 M.2 slot
* 1 audio jack
* 1 micro-USB port for serial debug
* 2 connectors for DSI displays
* 3 connectors for CSI cameras
* 1 connector for a eDP panel
* 1 MMC storage
This commit adds basic support in order to be able to boot.

v3:
* use plural for all pinctrl subnode names
* reorder all nodes in alphabetical order
* Remove invalid property for i2c6 pinctrl
* use interrupts-extended instead of interrupts/interrupt-parent
* rebase on top [v14,2/2] arm64: dts: Add mediatek SoC mt8195 and evaluation board
-> https://patchwork.kernel.org/project/linux-mediatek/patch/20220411022724.11005-3-tinghan.shen@mediatek.com/
v2:
* remove empty i2c nodes
* remove empty spi node
* remove unused pcie pinctrls
* fixup node nodes to not contains underscore
* rename mt6360 pmic node
* move mmc1 node right after mmc0 node
* use generic node name for gpio-keys
* uniformize pinctrl node names

Add basic device-tree for the MT8195 Demo board. The
Demo board is made by MediaTek and has a MT8195 SoC,
associated with the MT6359 and MT6360 PMICs, and
the MT7921 connectivity chip.
The IOs available on that board are:
* 1 USB Type-C connector with DP aux mode support
* 1 USB Type-A connector
* 1 full size HDMI RX and 1 full size HDMI TX connector
* 1 uSD slot
* 40 pins header
* SPI interface header
* 1 M.2 slot
* 1 audio jack
* 1 micro-USB port for serial debug
* 2 connectors for DSI displays
* 3 connectors for CSI cameras
* 1 connector for a eDP panel
* 1 MMC storage
This commit adds basic support in order to be able to boot.

v3:
* use plural for all pinctrl subnode names
* reorder all nodes in alphabetical order
* Remove invalid property for i2c6 pinctrl
* use interrupts-extended instead of interrupts/interrupt-parent
* rebase on top [v14,2/2] arm64: dts: Add mediatek SoC mt8195 and evaluation board
-> https://patchwork.kernel.org/project/linux-mediatek/patch/20220411022724.11005-3-tinghan.shen@mediatek.com/
v2:
* remove empty i2c nodes
* remove empty spi node
* remove unused pcie pinctrls
* fixup node nodes to not contains underscore
* rename mt6360 pmic node
* move mmc1 node right after mmc0 node
* use generic node name for gpio-keys
* uniformize pinctrl node names

v3:
* use plural for all pinctrl subnode names
* reorder all nodes in alphabetical order
* Remove invalid property for i2c6 pinctrl
* use interrupts-extended instead of interrupts/interrupt-parent
* rebase on top [v14,2/2] arm64: dts: Add mediatek SoC mt8195 and evaluation board
-> https://patchwork.kernel.org/project/linux-mediatek/patch/20220411022724.11005-3-tinghan.shen@mediatek.com/
v2:
* remove empty i2c nodes
* remove empty spi node
* remove unused pcie pinctrls
* fixup node nodes to not contains underscore
* rename mt6360 pmic node
* move mmc1 node right after mmc0 node
* use generic node name for gpio-keys
* uniformize pinctrl node names

* [PATCH v3 3/4] arm64: defconfig: enable MT6359 regulator driver

The PMIC regulators are essentials to be able to
boot MediaTek MT8195 based boards to userspace.
Like the other MediaTek PMIC regulator driver,
let's enable as well the one for the MT6359 PMIC.

Enable the charger and regulator driver for the
MT6360 PMIC. These drivers are essential for
some MediaTek MT8195 based boards to boot properly.
