This commit adds support for the Parade Tech TMA525B capacitive touch controller. The driver supports both interrupt-driven and polling modes, and can handle up to 4 simultaneous touch points. Key features: - I2C communication interface - Multi-touch support (up to 4 touch points) - Interrupt mode with GPIO callback support - Polling mode with timer - Power management support with PM notifier - Reset and power control via GPIO - Touch event tracking (down, contact, up) Signed-off-by: Kate Wang <yumeng.wang@nxp.com>
