rk3568 kernel adaptation button
Rockchip has launched a variety of high-performance ARM processors, and the button registration method can be realized through the Device Tree. The device tree is a data structure describing hardware devices, which can be loaded and parsed when the Linux kernel starts, so as to realize the management and control of hardware devices. Take conventional chips such as rk3288 rk3399 rk3568 rk3588 as examples, all of which support GPIO interrupt buttons, ADC serial buttons and PMIC attached buttons.
