* powerpc/fsl: add device tree binding for QE firmwareTimur Tabi2010-03-27
| | | | | | | | Define a binding for embedding a QE firmware blob into the device tree. Also define a new property for the QE node that links to a firmware node. Signed-off-by: Timur Tabi <timur@freescale.com> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
* powerpc: doc/dts-bindings: update doc of FSL I2C bindingsWolfgang Grandegger2010-03-07
| | | | | | | | | | | This patch adds the MPC5121 to the list of supported devices, enhances the doc of the "clock-frequency" property and removes the obsolete "cell-index", "device_type" and "fsl-i2c" property. Furthermore an example for the MPC5121 has been added. Signed-off-by: Wolfgang Grandegger <wg@denx.de> Reviewed-by: Wolfram Sang <w.sang@pengutronix.de> Signed-off-by: Ben Dooks <ben-linux@fluff.org>

| * fsldma: simplify IRQ probing and handlingIra Snyder2010-02-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The IRQ probing is needlessly complex. All off the 83xx device trees in arch/powerpc/boot/dts/ specify 5 interrupts per DMA controller: one for the controller, and one for each channel. These interrupts are all attached to the same IRQ line. This causes an interesting situation if two channels interrupt at the same time. The per-controller handler will handle the first channel, and the per-channel handler will handle the remaining channels. Instead of this mess, we fix the bug in the per-controller handler, and make it handle all channels that generated an interrupt. When a per-controller handler is specified in the device tree, we prefer to use the shared handler instead of the per-channel handler. The 85xx/86xx controllers do not have a per-controller interrupt, and instead use a per-channel interrupt. This behavior has not been changed. Signed-off-by: Ira W.

For one, it's a inefficient way to do it and requires led trigger support to be compiled in. But the real reason is that is produces a glitch on the LED. The GPIO is allocate with the LED *off*, then *later* when the trigger runs it is turned back on. If the LED was already on via the GPIO's reset default or action of the firmware, this produces a glitch where the LED goes from on to off to on. While normally this is fast enough that it wouldn't be noticeable to a human observer, there are still serious problems. One is that there may be something else on the GPIO line, like a hardware alarm or watchdog, that is fast enough to notice the glitch. Another is that the kernel may panic before the LED is turned back on, thus hanging with the LED in the wrong state. This is not just speculation, but actually happened to me with an embedded system that has an LED which should turn off when the kernel finishes booting, which was left in the incorrect state due to a bug in the OF LED binding code. We also let GPIO LEDs get their initial value from whatever the current state of the GPIO line is. On some systems the LEDs are put into some state by the firmware or hardware before Linux boots, and it is desired to have them keep this state which is otherwise unknown to Linux. This requires that the underlying GPIO driver support reading the value of output GPIOs. Some drivers support this and some do not. The platform device binding gains a field in the platform data "default_state" that controls this. There are three constants defined to select from on, off, or keeping the current state. The OpenFirmware binding uses a property named "default-state" that can be set to "on", "off", or "keep". The default if the property isn't present is off.

| * | powerpc/fsl: Update FSL esdhc bindingKumar Gala2009-05-19
| | | | | | | | | | | | | | | | | | | | | Updated the binding spec to use "fsl,eshdc" as the base compatible rather than the first chip in the family. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
| * | powerpc/qe: update QE Serial NumberHaiying Wang2009-05-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The latest QE chip may have more Serial Number(SNUM)s of thread to use. We will get the number of SNUMs from device tree by reading the new property "fsl,qe-num-snums", and set 28 as the default number of SNUMs so that it is compatible with the old QE chips' device trees which don't have this new property. The macro QE_NUM_OF_SNUM is defined as the maximum number in QE snum table which is 256. Also we update the snum_init[] array with 18 more new SNUMs which are confirmed to be useful on new chip.

| * powerpc/device-tree: Document MTD nodes with multiple "reg" tuplesStefan Roese2009-04-16
| | | | | | | | | | | | | | | | | | Add binding for mtd nodes with multiple reg tuples. Multiple reg tuples are used when the flash region covers multiple devices of the same type, but not necessarily the same size.
