For some boards the pmic interface is useful but the regulator interface (which comes with it) is too large. Allow them to be separated such that SPL can decide which it needs. Signed-off-by: Simon Glass <sjg@chromium.org>

config DM_PMIC

This config enables the driver-model PMIC support.

|
UCLASS_PMIC - designed to provide an I/O interface for PMIC devices.
|
|
For the multi-function PMIC devices, this can be used as parent I/O
|
|
device for each IC's interface. Then, each children uses its parent
|
|
for read/write. For detailed description, please refer to the files:
|
|

- 'include/power/pmic.h'

config PMIC_CHILDREN
|
|
bool "Allow child devices for PMICs"

depends on DM_PMIC
|
|
default y
|
|
---help---
|
|
This allows PMICs to support child devices (such as regulators) in
|
|
SPL. This adds quite a bit of code so if you are not using this
|
|
feature you can turn it off. Most likely you should turn it on for
|
|
U-Boot proper.

config SPL_PMIC_CHILDREN
|
|
bool "Allow child devices for PMICs in SPL"
|

depends on DM_PMIC
|
|
default y
|
|
---help---
|
|
This allows PMICs to support child devices (such as regulators) in
|
|
SPL. This adds quite a bit of code so if you are not using this
|
|
feature you can turn it off. In this case you may need a 'back door'
|
|
to call your regulator code (e.g. see rk808.c for direct functions
|
|
for use in SPL).

---help---
|
|
This PMIC includes 4 DC/DC step-down buck regulators and 8 low-dropout
|
|
regulators (LDOs). It also provides some GPIO, reset and battery
|
|
functions. It uses an I2C interface and is designed for use with
|
|
tablets and smartphones.

The Rockchip RK808 PMIC provides four buck DC-DC convertors, 8 LDOs,
|
|
an RTC and two low Rds (resistance (drain to source)) switches. It is
|
|
accessed via an I2C interface. The device is used with Rockchip SoCs.

---help---
|
|
Enable the driver for Sandbox PMIC emulation. The emulated PMIC device
|
|
depends on two drivers:
|
|
- sandbox PMIC I/O driver - implements dm pmic operations
|
|
- sandbox PMIC i2c emul driver - emulates the PMIC's I2C transmission
|
|
|
|
A detailed information can be found in header: '<power/sandbox_pmic.h>'

The Sandbox PMIC info:
|
|
* I/O interface:
|
|
- I2C chip address: 0x40
|
|
- first register address: 0x0
|
|
- register count: 0x10
|
|
* Adjustable outputs:
|
|
- 2x LDO
|
|
- 2x BUCK
|
|
- Each, with a different operating conditions (header).
|
|
* Reset values:
|
|
- set by i2c emul driver's probe() (defaults in header)

The S5M8767 PMIC provides a large array of LDOs and BUCKs for use
|
|
as a SoC power controller. It also provides 32KHz clock outputs. This
|
|
driver provides basic register access and sets up the attached
|
|
regulators if regulator support is enabled.
