drivers: regulator: fixed: add u-boot, off-on-delay-us

2018-08-20T00:38:39+00:00

Add u-boot,off-on-delay-us for fixed regulator.

Depends on board design, the gpio regulator sometimes
connects with a big capacitance. When need to off, then
on the regulator, if there is no enough delay,
the voltage does not drop to 0, so introduce this
property to handle such case.

power: regulator: stpmu1: add power off delay

2018-07-19T20:31:36+00:00

This patch adds a delay when regulators are disabled.
This delay is set to 5 ms to cover all use cases.
The worst use case actually seen is during a SD card power cycle.

power: pmic: Let PFUZE3000 see all 256 registers

2018-06-27T07:47:46+00:00

The PFUZE3000 uses registers addresses up to 0xff.

The DM pfuze100 driver supports both pfuze100 and pfuze3000.  Allow it
to use the device type to return the correct number of registers.

Also rename the too generic PMIC_NUM_OF_REGS enumeration value for
pfuze3000 to match the other "PFUZE3000_" prefixed enumerations and the
pfuze100 enumeration value PFUZE100_NUM_OF_REGS.

sandbox: Rewrite i2c_pmic_emul.c to support PMIC with 3 bytes transmission

2018-05-18T06:27:26+00:00

This change enables support for MC34708 PMIC in sandbox. Now we can
emulate the I2C transfers larger than 1 byte.

Notable changes for this driver:

- From now on the register number is not equal to index in the buffer,
  which emulates the PMIC registers

- The PMIC register's pool is now dynamically allocated up till
  64 regs * 3 bytes each = 192 B
