Hi everyone,
This is v5 of the MT8186 Chromebook device tree series. This series also
depends on MT7921S Bluetooth [1] and IT6505 audio [2] bindings.
Changes since v4:
- Rebase and fit in mt8188-evb in board DT binding
- Change "touchpad" to "trackpad" in descriptions and commit logs
- Drop #address-cells and #size-cells from it6505 and usb_host1 nodes
- Drop "ports" nodes from type-c nodes
- Fix pinmux node names
- Split anx7625 reset and power-en pins into separate pinmux nodes
Not changed: "/delete-node/ trackpad@15" is still present. See patch 6
footer.
Changes since v3:
- Collected reviewed-by from Angelo
- Reorder some properties to conform better to the newly proposed DT
style guidelines
- Drop unused labels
- Rename bt-sco node name to bt-sco-codec
- Drop i2s*-share properties from afe node
- Drop aud_gpio_tdm_{on,off} pinctrl nodes
- Replace interrupts with interrupts-extended in tpm node
- Enable adsp device
Changes since v2:
- Picked up Conor's ack
- Renamed remaining "touchpad" nodes to "trackpad"
- Dropped pinctrl from tentacruel/tentacool second source trackpad
Changes since v1:
- Reorder SKU numbers in descending order.
- Fixed pinconfig node names
- Moved pinctrl-* properties after interrupts-*
- Switched to interrupts-extended for external components
- Marked ADSP as explicitly disabled, with a comment explaining that it
stalls the system
- Renamed "touchpad" to "trackpad"
- Dropped bogus "no-laneswap" property from it6505 node
- Moved "realtek,jd-src" property to after all the regulator supplies
- Switched to macros for MT6366 regulator "regulator-allowed-modes"
- Renamed "vgpu" regulator name to allow coupling, with a comment
containing the name used in the design
- Renamed "cr50" node name to "tpm"
- Moved trackpad_pins reference up to i2c2; workaround for second source
component resource sharing.
- Fix copyright year
- Fixed touchscreen supply name
- Mark missing components as disabled instead of deleting the node
- Dropped reset-gpios from touchscreen nodes
- Drop status = "okay", which is the default
This series adds device trees for the various MT8186 Chromebooks that
were initially released. These are the Tentacruel / Tentacool devices
released by ASUS, and the Steelix / Rusty / Magneton devices released
by Lenovo. The device trees are taken from the downstream ChromeOS v5.15
kernel, ported to mainline and cleaned up.
Corsola is the Google codename given to the MT8186 platform. This
platform has two reference designs, Krabby and Kingler. Kingler was not
used in any actual product, and is therefor not included. Steelix is
an alternative design put forward and is effectively a mix-and-match of
the two reference designs.
Most of the core design is shared between the variants. The differences
are on which external components, such as the display bridges, are used.
Patch 1 cleans up the current list of MediaTek boards. The entries are
reordered by SoC model first, then by board name.
Patch 2 through 5 add DT binding entries for the Tentacruel/Tentacool,
Steelix, Rusty, and Magneton Chromebooks.
Patch 6 through 9 add board device tree files for these devices. Patch 6
also adds the corsola dtsi file for the commonalities between the designs,
as well as a dtsi file for the krabby reference design.
Currently external display support is missing. Audio is not working, as
enabling the audio DSP causes my test systems to hang.
Please have a look and test if possible.
Regards
ChenYu
