MediaTek ARM64 DTS updates for v6.11
This introduces the new Airoha (MediaTek) EN7581 home networking
platform (routers) in early stages, but with support for its
Evaluation Board, a few more MediaTek based machines, and
improvements for existing ones.
For the MT7981 router SoC we get pinctrl support, along with the
enablement of its watchdog, eFuse/nvmem, I2C and integrated WiFi
controller, other than the introduction of new machines based on
this chip: the Cudy WR3000 V1 router and the OpenWRT One.
MT7986 gets a new machine: the BananaPi R3 Mini.
Some advancements have been done also on the MT7988 SoC, which
gains support for its I2C, PWM and USB XHCI controllers.
MediaTek Genio SoCs also get attention, with the introduction of a
basic device tree for the MT8390 Genio 700-EVK board, and for the
MT8395 Genio 1200 powered Kontron 3.5"-SBC-i1200.
Additionally, the Genio 1200 Radxa NIO12L board gets support for
USB Role Switching and proper PCI-Express controller PM suspend
and resume, other than finally enabling CPU and GPU frequency
and voltage scaling for improved efficiency.
Speaking of MediaTek Kompanio SoCs (Chromebooks) instead, thanks
to community interest and help in testing, there comes support for
the MT8195-powered HP Chromebook X360 13b-ca0002sa, while Google
contributed support for the MT8186-powered Acer Chromebook 311.
Moreover, MT8188 gets support for its integrated power domains,
other than its Global Command Engine (GCE) mailboxes, initial
basic support for the VDO0/1 blocks for multimedia, and its GPU
(ARM Mali G57-MC3, Valhall-JM) with Panfrost.
Besides that, this also adds a few other cleanups and improvements
for all machines using the MT8183, MT8192, MT8195/MT8395 SoCs and
adds generation of symbols on base devicetrees of machines using
Device Tree Overlay(s) (DTBO).
In particular:
- The MediaTek Smart Voltage Scaling (SVS) is now fully working
those SoCs, bringing further power efficiency improvements;
- Thermal zones were refactored on MT8183 for consistency with
the other MediaTek SoCs and for readability
- Sound DAI links are now consistently specified in device tree
on MT8195 and MT8186 machines
- Newly supported machines/boards
- EN7581: EVK
- MT7981: Cudy WR3000 V1, OpenWRT One
- MT7986: BananaPi R3 Mini
- MT8186: Acer Chromebook 311 (Corsola Voltorb)
- MT8195: HP Chromebook X360 13b-ca0002sa (Cherry Dojo)
- MT8390/8188: Genio 700 EVK
- Some cleanups for unused/legacy devicetree properties
arm64: dts: mediatek: Declare drive-strength numerically
On some devicetrees, the drive-strength property gets assigned a
MTK_DRIVE_(x)_mA definition, which matches with (x).
For example, MTK_DRIVE_8mA equals to 8 and MTK_DRIVE_30mA equals
to 30.
Also keeping in mind that the drive-strength property is, by
(binding) definition, taking a number in milliamperes unit,
change all devicetrees to avoid the usage of any MTK_DRIVE_(x)
definition.
