linux-toradex.git/include/linux/mfd/atc260x, branch master Linux kernel for Apalis and Colibri modules mfd: Add MFD driver for ATC260x PMICs 2021-03-10T11:10:23+00:00 Cristian Ciocaltea cristian.ciocaltea@gmail.com 2021-01-26T09:55:59+00:00 f7cb7fe34db9f32e8b1c13ecc823112480b875f8 Add initial support for the Actions Semi ATC260x PMICs which integrates Audio Codec, Power management, Clock generation and GPIO controller blocks. For the moment this driver only supports Regulator, Poweroff and Onkey functionalities for the ATC2603C and ATC2609A chip variants. Since the PMICs can be accessed using both I2C and SPI buses, the following driver structure has been adopted: -----> atc260x-core.c (Implements core functionalities) / ATC260x --------> atc260x-i2c.c (Implements I2C interface) \ -----> atc260x-spi.c (Implements SPI interface - TODO) Co-developed-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Signed-off-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Signed-off-by: Cristian Ciocaltea <cristian.ciocaltea@gmail.com> Signed-off-by: Lee Jones <lee.jones@linaro.org> 
Add initial support for the Actions Semi ATC260x PMICs which integrates
Audio Codec, Power management, Clock generation and GPIO controller
blocks.

For the moment this driver only supports Regulator, Poweroff and Onkey
functionalities for the ATC2603C and ATC2609A chip variants.

Since the PMICs can be accessed using both I2C and SPI buses, the
following driver structure has been adopted:

           -----> atc260x-core.c (Implements core functionalities)
          /
ATC260x --------> atc260x-i2c.c (Implements I2C interface)
          \
           -----> atc260x-spi.c (Implements SPI interface - TODO)
