cypress4025lqi_driver.c驱动编译进内核 修改Makefile，添加： obj-$(CONFIG_INPUT_CYPRESS4025LQI) += cypress4025lqi_driver.o 修改Kconfig，添加： config INPUT_CYPRESS4025LQI tristate "CONFIG_INPUT_CYPRESS4025LQI i2c transfer data" help depends on i2c bug
leds-aw9120.c 驱动编译进内核 修改Makefile，添加： # LED AW9120 Drivers obj-$(CONFIG_LEDS_AW9120) += leds-aw9120.o 修改Kconfig，添加： config LEDS_AW9120 tristate "LED Support for AWINIC WA9120 I2C LED controller family" depends on LEDS_CLASS && I2C && OF select REGMAP_I2C help This option enables support for LEDs connected to AWINIC WA9120 fancy LED driver chips accessed via the I2C bus. Driver supports individual PWM brightness control for each channel.
This driver can also be built as a module. If so the module will be
called leds-aw9102.c
编译时候是能CONFIG_INPUT_CYPRESS4025LQI=y, CONFIG_LEDS_AW9120=y 即可编译到内核，或者直接再Makefile写死obj-y += cypress4025lqi_driver.o
