These blocks are found in a wide range of Qualcomm PMICs. + The light pulse generator (LPG) can also be used independently to output PWM + signal for standard PWM applications. In this scenario, the LPG output should + be routed to a specific PMIC GPIO by setting the GPIO pin mux to the special + functions indicated in the datasheet, the TRILED driver for the channel will + not be enabled in this configuration. properties: compatible: |
