dm: core: Add dev_get_addr_ptr() to return a pointer to the reg address

2016-04-25T05:30:16+00:00

On some platforms (e.g. x86), the return value of dev_get_addr() can't
be assigned to a pointer type variable directly. As there might be a
difference between the size of fdt_addr_t and the pointer type. On
x86 for example, "fdt_addr_t" is 64bit but "void *" only 32bit. So
assigning the register base directly in dev_get_addr() results in this
compilation warning:
  warning: cast to pointer from integer of different size

This patch introduces the new function dev_get_addr_ptr() that
returns a pointer to the 'reg' address that can be used by drivers
in this case.

fdt: implement dev_get_addr_name()

2016-04-15T14:14:37+00:00

This function parses the reg property based on an index found in the
reg-names property. This is required for bindings that are written
using reg-names rather than hard-coding indices in reg.

drivers: Add SPMI bus uclass

2016-04-01T21:18:12+00:00

Qualcom processors use proprietary bus to talk with PMIC devices -
SPMI (System Power Management Interface).
On wiring level it is similar to I2C, but on protocol level, it's
multi-master and has simple autodetection capabilities.
This commit adds simple uclass that provides bus read/write interface.

serial: add BCM283x mini UART driver

2016-03-27T13:12:52+00:00

The RPi3 typically uses the regular UART for high-speed communication with
the Bluetooth device, leaving us the mini UART to use for the serial
console. Add support for this UART so we can use it.

serial: pl01x: Add support for devices with the rate pre-configured.

2016-03-22T16:16:12+00:00

For Raspberry Pi, we had the input clock rate to the pl011 fixed in
the rpi.c file, but it may be changed by firmware due to user changes
to config.txt.  Since the firmware always sets up the uart (default
115200 output unless the user changes it), we can just skip our own
uart init to simplify the boot process and more reliably get serial
output.

dm: core: Add uclass_first_device_err() to return a valid device

2016-03-14T21:34:50+00:00

A common pattern is to call uclass_first_device() and then check if it
actually returns a device. Add a new function which does this, returning
an error if there are no devices in that uclass.

driver for sandbox. Add this information to platform data and copy it to
