[PATCH 0/2] Add QCOM PMIC PWM driver
From: Fenglin Wu
Date: Tue Apr 27 2021 - 06:24:26 EST
Add PWM driver to support PWM modules inside QCOM PMIC chips which are accessed
through SPMI bus. Normally, there would be multiple PWM modules with adjacent
address spaces present in one PMIC chip, and each PWM module has 0x100 size of
address space. With this driver, a pwm_chip with multiple pwm_device individuals
is created, and each pwm_device individual is corresponding to one PWM module.
