2010-08-04Documentation: update broken web addresses.Justin P. Mattock1-1/+1
Below you will find an updated version from the original series bunching all patches into one big patch updating broken web addresses that are located in Documentation/* Some of the addresses date as far far back as 1995 etc... so searching became a bit difficult, the best way to deal with these is to use web.archive.org to locate these addresses that are outdated. Now there are also some addresses pointing to .spec files some are located, but some(after searching on the companies site)where still no where to be found. In this case I just changed the address to the company site this way the users can contact the company and they can locate them for the users. Signed-off-by: Justin P.

2010-08-01powerpc/5200/i2c: improve i2c bus error recoveryAlbrecht Dreß1-0/+2
This patch improves the recovery of the MPC's I2C bus from errors like bus hangs resulting in timeouts: 1. make the bus timeout configurable, as it depends on the bus clock and the attached slave chip(s); default is still 1 second; 2. detect any of the cases indicated by the CF, BB and RXAK MSR flags if a timeout occurs, and add a missing (required) MAL reset; 3. use a more reliable method to fixup the bus if a hang has been detected. The sequence is sent 9 times which seems to be necessary if a slave "misses" more than one clock cycle. For 400 kHz bus speed, the fixup is also ~70us (81us vs. 150us) faster. Tested on a custom Lite5200b derived board, with a Dallas RTC, AD sensors and NXP IO expander chips attached to the i2c. Changes vs. v1: - use improved bus fixup sequence for all chips (not only the 5200) - calculate real clock from defaults if no clock is given in the device tree - better description (I hope) of the changes. I didn't split the changes in this file into three parts as recommended by Grant, as they actually belong together (i.e. they address one single problem, just in three places of one single source file).

2010-08-01powerpc/fsl-diu-fb: Support setting display mode using EDIDAnatolij Gustschin1-0/+6
Adds support for encoding display mode information in the device tree using verbatim EDID block. If the EDID entry in the DIU node is present, the driver will build mode database using EDID data and allow setting the display modes from this database. Otherwise display mode will be set using mode entries from driver's internal database as usual. This patch also updates device tree bindings.

Here the possible values of "reset_type": 1 - PPC4xx core reset 2 - PPC4xx chip reset 3 - PPC4xx system reset (default) This will be used by a new PPC440SPe board port, which needs a "chip reset" instead of the default "system reset" to be asserted.

2010-02-02fsldma: simplify IRQ probing and handlingIra Snyder1-0/+8
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.

2009-06-23leds: Add options to have GPIO LEDs start on or keep their stateTrent Piepho1-1/+16
There already is a "default-on" trigger but there are problems with it. 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.

2009-06-21sdhci: Add support for hosts that are only capable of 1-bit transfersAnton Vorontsov1-0/+2
Some hosts (hardware configurations, or particular SD/MMC slots) may not support 4-bit bus. For example, on MPC8569E-MDS boards we can switch between serial (1-bit only) and nibble (4-bit) modes, thought we have to disable more peripherals to work in 4-bit mode. Along with some small core changes, this patch modifies sdhci-of driver, so that now it looks for "sdhci,1-bit-only" property in the device-tree, and if specified we enable a proper quirk.
