mfd: cpcap: Add minimal support
Many Motorola phones like droid 4 are using a custom PMIC called CPCAP or 6556002. We can support it's core features quite easily with regmap_spi and regmap_irq. The children of cpcap, such as regulators, ADC and USB, can be just regular device drivers and defined in the dts file. They get probed as we call of_platform_populate() at the end of our probe, and then the children can just call dev_get_regmap(dev.parent, NULL) to get the regmap.

Motorola CPCAP PMIC device tree binding
|
||||||
|
|
||||||
|
Required properties:
|
||||||
|
- compatible : One or both of "motorola,cpcap" or "ste,6556002"
|
||||||
|
- reg : SPI chip select
|
||||||
|
- interrupt-parent : The parent interrupt controller
|
||||||
|
- interrupts : The interrupt line the device is connected to
|
||||||
|
- interrupt-controller : Marks the device node as an interrupt controller
|
||||||
|
- #interrupt-cells : The number of cells to describe an IRQ, should be 2
|
||||||
|
- #address-cells : Child device offset number of cells, should be 1
|
||||||
|
- #size-cells : Child device size number of cells, should be 0
|
||||||
|
- spi-max-frequency : Typically set to 3000000
|
||||||
|
- spi-cs-high : SPI chip select direction
|
||||||
|
|
||||||
|
Example:
|
||||||
|
|
||||||
|
&mcspi1 {
|
||||||
|
cpcap: pmic@0 {
|
||||||
|
compatible = "motorola,cpcap", "ste,6556002";

reg = <0>; /* cs0 */

interrupt-parent = <&gpio1>;
|

|
interrupts = <7 IRQ_TYPE_EDGE_RISING>;

||||||

#interrupt-cells = <2>;

#address-cells = <1>;
|

#size-cells = <0>;

Say yes here if you want to include driver for CPCAP.
|

It is used on many Motorola phones and tablets as a PMIC.
|

At least Motorola Droid 4 is known to use CPCAP.
