From: Fenglin Wu <fenglinw@xxxxxxxxxxxxxx> QTI TRI_LED module and LPG modules are existing in some Qualcomm PMICs like PMI8998, PM660, etc. TRI_LED module has 3 LED drivers and each is controlled by a PWM channel used for LED dimming or blinking. LPG (Light Pulse Generator) module can be configured to operate in PWM mode to output PWM signal with a fixed amplitude or in LUT (Look Up Table) mode to output PWM signal with a modulated amplitude. Normally, each LED driver in TRI_LED module is controlled by the output of a LPG module. This patchset adds the support of registering TRI_LED as LED devices and adding LPGs as PWM devices, but only the LPG PWM mode is supported. LUT mode is not included because current PWM driver framework doesn't support hardware autonomously modulating amplitude with vary duties. This is going to be supported in next patchset with some PWM framework change.
