powerpc/ibmebus: Restore "name" sysfs attribute on ibmebus devices

2008-08-19T23:50:21+00:00

Recent of_platform changes made of_bus_type_init() overwrite the bus
type's .dev_attrs list, meaning that the "name" attribute that ibmebus
devices previously had is no longer present.  This is a user-visible
regression which breaks the userspace eHCA support, since the eHCA
userspace driver relies on the name attribute to check for valid
adapters.

This fixes it by providing the "name" attribute in the generic OF
device code instead.  Tested on POWER.

spi: Add OF binding support for SPI busses

2008-07-26T02:34:40+00:00

This patch adds support for populating an SPI bus based on data in the
OF device tree.  This is useful for powerpc platforms which use the
device tree instead of discrete code for describing platform layout.

of: adapt of_find_i2c_driver() to be usable by SPI also

2008-07-26T02:25:13+00:00

SPI has a similar problem as I2C in that it needs to determine an
appropriate modalias value for each device node.  This patch adapts
the of_i2c of_find_i2c_driver() function to be usable by of_spi also.

gpiolib: allow user-selection

2008-07-25T17:53:30+00:00

This patch adds functionality to the gpio-lib subsystem to make it
possible to enable the gpio-lib code even if the architecture code didn't
request to get it built in.

The archtitecture code does still need to implement the gpiolib accessor
functions in its asm/gpio.h file.  This patch adds the implementations for
x86 and PPC.

With these changes it is possible to run generic GPIO expansion cards on
every architecture that implements the trivial wrapper functions.  Support
for more architectures can easily be added.

powerpc/mpc5200: Fix wrong 'no interrupt' handling in of_i2c

2008-07-22T07:13:04+00:00

If an I2C device node does not specify an interrupt, the .irq member of the
board_info struct was set to -1. This caused crashes on following
irq_dispose_mappings. Leave it NO_IRQ as returned from irq_of_parse_and_map.
(Suggesting -1 as 'i2c-no-irq' used to be a bug in linux/i2c.h.)

rtc-ds1374: rename device to just "ds1374"

2008-06-06T18:29:10+00:00

Change the name of the device from "rtc-ds1374" to just "ds1374", to match
what all other RTC drivers do.  I seem to remember that this name was
chosen to avoid possible confusion with an older ds1374 driver, but that
driver was removed 3 months ago.

[POWERPC] of/gpio: Use dynamic base allocation

2008-05-23T05:27:19+00:00

Since the "gpiolib: dynamic gpio number allocation" patch was recently
merged into Linus' tree (commit 8d0aab2f16c4fa170f32e7a74a52cd0122bbafef),
we can use dynamic GPIO base allocation now.

This, in turn, removes number of gpios per chip constraint.
