The Waveshare DSI TOUCH family of DSI panel kits feature different DSI
video-mode panels, bundled with the separate controlling circuit,
produing necessary voltages from the 3.3V and 5V supplies. Extend panel
drivers to support those Waveshare panels and also add GPIO driver for
the onboard control circuitry.

Changes in v3:
- Fix another typo in the focaltech,ota7290b schema, sorted out voltage
supplies in the schema and in the driver
- Dropped Ricardo's T-B from bindings patch (Krzysztof)
- In the Waveshare GPIO driver bumped max register to REG_VERSION (Jie
Gan)
- Add a lanes vs config check in the JD9365 driver (Jie Gan)
- Link to v2: https://patch.msgid.link/20260411-waveshare-dsi-touch-v2-0-75cdbeac5156@oss.qualcomm.com
Changes in v2:
- Fixed errors in focaltech,ota7290b and waveshare,dsi-touch-gpio schemas
- Split the JD9365 patch, making the changes more obvious (and
describing panel classes)
- Cleaned up GPIO driver: moved NUM_GPIOS from the enum, switched to
guard(), added regmap error handling, dropped
waveshare_gpio_i2c_read() (Bartosz)
- Link to v1: https://patch.msgid.link/20260401-waveshare-dsi-touch-v1-0-5e9119b5a014@oss.qualcomm.com
