Subject: [PATCH RFC/RFT 0/3] Add support to Novatek's touch IC nt36xxx
Date: Tue, 15 Oct 2024 20:53:28 +0800 [thread overview]
Message-ID: <20241015-nt36xxx-v1-0-3919d0bffee6@gmail.com> (raw)
Initially support for nt36xxx series spi device. Below
list all supported varients:
- NT36675
- NT36672A
- NT36772(?)
- NT36525
- NT36676F
I had tested it with Redmi note 9 pro, aka NT36675 chip.
This series is based on my repo below:
https://github.com/99degree/linux/tree/nt36xxx
There is a boot-and-functional tree for miatoll device:
https://github.com/99degree/linux/tree/working-20241015
And the older dev history:
https://github.com/99degree/linux/tree/nt36xxx_old
https://github.com/99degree/linux/tree/working-20230528/drivers/input/touchscreen
This driver is based on
AngeloGioacchino Del Regno for i2c based drive
https://patchwork.kernel.org/project/linux-input/cover/20201028221302.66583-1-kholk11@gmail.com/#24831734
_AND_
Neil Armstrong for the spi device codes
https://patchwork.kernel.org/project/linux-input/patch/20231213-topic-goodix-berlin-upstream-initial-v13-2-5d7a26a5eaa2@linaro.org/
Download fw function is adapted from original vendor driver
https://github.com/LineageOS/android_kernel_xiaomi_sm6250/tree/lineage-21/drivers/input/touchscreen/nt36xxx_spi/
Panel follower functionality is finally added.
Since the driver is split into core+spi so i2c function is relatively
easily to add.
