regulator: fixed: obey startup delay

2016-09-06T17:18:21+00:00

When enabling a fixed regulator, it may take some time to rise to the
correct voltage.  If we do not delay here then subsequent operations
will fail.

gpio: Add driver for TI PCF8575 I2C GPIO expander

2016-08-08T17:32:53+00:00

TI's PCF8575 is a 16-bit I2C GPIO expander.The device features a
16-bit quasi-bidirectional I/O ports. Each quasi-bidirectional I/O can
be used as an input or output without the use of a data-direction
control signal. The I/Os should be high before being used as inputs.
Read the device documentation for more details[1].

This driver is based on pcf857x driver available in Linux v4.7 kernel.
It supports basic reading and writing of gpio pins.

dt-bindings: add Tegra186 BPMP I2C binding

2016-08-04T20:36:59+00:00

In Tegra186, the BPMP (Boot and Power Management Processor) owns certain
HW devices, such as the I2C controller for the power management I2C bus.
Software running on other CPUs must perform IPC to the BPMP in order to
execute transactions on that I2C bus. This binding describes an I2C bus
that is accessed in such a fashion.

dt-bindings: allow child nodes inside the Tegra BPMP

2016-08-04T20:36:59+00:00

The BPMP implements some services which must be represented by separate
nodes. For example, it can provide access to certain I2C controllers, and
the I2C bindings represent each I2C controller as a device tree node.
Update the binding to describe how the BPMP supports this.

ARM: tegra: add BPMP DT bindings

2016-08-04T20:36:58+00:00

The Tegra BPMP (Boot and Power Management Processor) is a separate
auxiliary CPU embedded into Tegra to perform power management work, and
controls related features such as clocks, resets, power domains, PMIC I2C
bus, etc. These bindings dictate how to represent the BPMP in device tree.

ARM: tegra: adapt to latest HSP DT binding

2016-08-04T20:36:58+00:00

The DT binding for the Tegra186 HSP module apparently wasn't quite final
when I posted initial U-Boot support for it. Add the final DT binding doc
and adapt all code and DT files to match it.
