drivers/base: fix compiler warning in SoC export driver - idr should be ida

2017-03-31T08:25:18+00:00

This fixes:
  note: expected ‘struct ida *’ but argument is of type ‘struct idr *’
  warning: passing argument 1 of ‘ida_pre_get’ from incompatible pointer type

drivers/base: add bus for System-on-Chip devices

2017-03-31T08:24:52+00:00

Traditionally, any System-on-Chip based platform creates a flat list
of platform_devices directly under /sys/devices/platform.

In order to give these some better structure, this introduces a new
bus type for soc_devices that are registered with the new
soc_device_register() function.  All devices that are on the same
chip should then be registered as child devices of the soc device.

The soc bus also exports a few standardised device attributes which
allow user space to query the specific type of soc.

In rpm_suspend, when suspend fail,
before going to reschedule another autosuspend,
wake_up_all is required to avoid remote wakeup
issues.

regmap: add support for non contiguous status to regmap-irq

2012-07-03T22:03:33+00:00

In some chips the IRQ status registers are not contiguous in the register
map but spaced at even spaces. This is an easy case to handle with minor
changes. It is assume for this purpose that the stride for status is
equal to the stride for mask/ack registers as well.

regmap: implement register striding

2012-04-15T21:58:10+00:00

regmap_config.reg_stride is introduced. All extant register addresses
are a multiple of this value. Users of serial-oriented regmap busses will
typically set this to 1. Users of the MMIO regmap bus will typically set
this based on the value size of their registers, in bytes, so 4 for a
32-bit register.

Throughout the regmap code, actual register addresses are used. Wherever
the register address is used to index some array of values, the address
is divided by the stride to determine the index, or vice-versa. Error-
checking is added to all entry-points for register address data to ensure
that register addresses actually satisfy the specified stride. The MMIO
bus ensures that the specified stride is large enough for the register
size.

regmap: allow regmap instances to be named

2012-04-15T21:47:14+00:00

Some devices have multiple separate register regions. Logically, one
regmap would be created per region. One issue that prevents this is that
each instance will attempt to create the same debugfs files. Avoid this
by allowing regmaps to be named, and use the name to construct the
debugfs directory name.
