LP3943 is an integrated device capable of driving 16 output channels. It can be used for GPIO expander and PWM generators. LP3493 registers are controlled via the I2C interface.
This patch-set consists of four parts - MFD, GPIO, PWM and documents. Major updates in v3: * MFD Lee Jones pointed confusing pin number notation. Now, each output pin number is exactly matched to each enum value. LP3943 has a static configuration from platform data or the device tree, So, I keep the driver structure instead of using the pin control subsystem. (https://lkml.org/lkml/2013/8/14/490) * PWM Do not emulate 'set_polarity' function in case of unsupported feature by the chip. Code fixes based on Thierry Reding's comments. (https://lkml.org/lkml/2013/8/14/188) * Documentation From Thierry's suggestion, detailed driver description was moved to 'Documentation/lp3943.txt'. Fix device tree bindings from maintainers' comments.
