Extend the novatek touchscreen driver to support NT36672A chip which is found in phones like qcom/sdm845-xiaomi-beryllium-tianma.dts. Added devicetree support for the driver and used i2c chip data to handle the variation in chip id and wake type. Also added vcc and iovcc regulators which are used to power the touchscreen hardware. Signed-off-by: Joel Selvaraj <joelselvaraj.oss@xxxxxxxxx> --- Changes in v5: - Made the chip data a local variable as it is only used during probe. - Handle the regulator disable correctly for all exit paths in probe. - Link to v4: https://lore.kernel.org/r/20240601-nvt-ts-devicetree-regulator-support-v4-0-e0c0174464c4@xxxxxxxxx Changes in v4: - Use lowercase i2c device id as suggested by Hans de Goede. - Disable the regulators after nvt_ts_read_data during probe. - Link to v3: https://lore.kernel.org/r/20240526-nvt-ts-devicetree-regulator-support-v3-0-aa88d10ccd9a@xxxxxxxxx Changes in v3: - Fix indentation in the binding as suggested by Krzysztof Kozlowski. - Picked up Krzysztof Kozlowski's Reviewed-by tag for the binding. - Link to v2: https://lore.kernel.org/r/20240524-nvt-ts-devicetree-regulator-support-v2-0-b74947038c44@xxxxxxxxx Changes in v2: - The generic i2c device id is now replaced with the correct IC variant provided by Hans de Goede - Updated the bindings to reflect the latest changes and also incorporated the suggestions provided by Krzysztof Kozlowski - Link to v1: https://lore.kernel.org/r/20240521-nvt-ts-devicetree-regulator-support-v1-0-8d766c639dca@xxxxxxxxx --- Joel Selvaraj (3): Input: novatek-nvt-ts: replace generic i2c device id with specific IC variant dt-bindings: input: document Novatek NVT touchscreen controller Input: novatek-nvt-ts: add support for NT36672A touchscreen .../bindings/input/touchscreen/novatek,nvt-ts.yaml | 62 ++++++++++++++++++++ MAINTAINERS | 1 + drivers/input/touchscreen/novatek-nvt-ts.c | 67 ++++++++++++++++++++-- drivers/platform/x86/x86-android-tablets/other.c | 2 +- 4 files changed, 125 insertions(+), 7 deletions(-) --- base-commit: 6578aac6a270bd6deb9f9319b991dd430de263dd change-id: 20240518-nvt-ts-devicetree-regulator-support-ac9e49b78a16 Best regards, -- Joel Selvaraj <joelselvaraj.oss@xxxxxxxxx>
