OF-device: Don't overwrite numa_node in device registration

2008-10-31T05:12:01Z

Currently, the numa_node of OF-devices will be overwritten during device_register, which simply sets the node to -1. On cell machines, this means that devices can't find their IOMMU, which is referenced through the device's numa node. Set the numa node for OF devices with no parent, and use the lower-level device_initialize and device_add functions, so that the node is preserved. We can remove the call to set_dev_node in of_device_alloc, as it will be overwritten during register. Signed-off-by: Jeremy Kerr Signed-off-by: Paul Mackerras

of/spi: Support specifying chip select as active high via device tree

2008-10-21T04:34:01Z

The patch allows to specify that an SPI device needs an active high chip select. Signed-off-by: Wolfgang Ocker Signed-off-by: Kumar Gala

of: Format string bug in drivers/of/of_i2c.c

2008-10-21T04:17:49Z

Format string bug. Not exploitable, as this is only writable by root, but worth fixing all the same. See 326f6a5c9c9e1a62aec37bdc0c3f8d53adabe77b Signed-off-by: Benjamin Herrenschmidt

of: Add new helper of_parse_phandles_with_args()

2008-10-12T23:55:47Z

The helper is factored out of of_get_gpio(). Will be used by the QE pin multiplexing functions (they need to parse the gpios = <> too). Signed-off-by: Anton Vorontsov Signed-off-by: Benjamin Herrenschmidt

powerpc/of-bindings: Don't support linux, "compatible" values

2008-10-10T04:55:18Z

Compatible property values in the form linux, is not documented anywhere and using it leaks Linux implementation details into the device tree data (which is bad). Remove support for compatible values of this form. If any platforms exist which depended on this code (and I don't know of any), then they can be fixed up by adding legacy translations to the lookup table in this file.

OF: add fsl,mcu-mpc8349emitx to the exception list

2008-10-08T17:37:51Z

of/base.c matches on the first (most specific) entries, which isn't quite practical but it was discussed[1] that this won't change. The bindings specifies verbose information for the devices, but it doesn't fit in the I2C ID's 20 characters limit. The limit won't change[2], and the bindings won't change either as they're correct. So we have to put an exception for the MPC8349E-mITX-compatible MCUs.

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

2008-08-19T23:50:21Z

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. Signed-off-by: Joachim Fenkes Signed-off-by: Paul Mackerras

spi: Add OF binding support for SPI busses

2008-07-26T02:34:40Z

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. Signed-off-by: Grant Likely
