2008-01-28spi_mpc83xx: use brg-frequency for SPI in QEAnton Vorontsov2-18/+34
In case of QE we can use brg-frequency (which is qeclk/2). Thus no need to divide sysclk in the spi_mpc83xx. This patch also adds code to use get_brgfreq() on QE chips.

2008-01-28ucc_geth: get rid of device_type for mdioAnton Vorontsov5-7/+7
device_type property is bogus, thus use proper compatible. Also change compatible property to "fsl,ucc-mdio". Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-01-28[POWERPC] QE: get rid of most device_types and modelAnton Vorontsov11-66/+117
Now we're searching for "fsl,qe", "fsl,qe-muram", "fsl,qe-muram-data" and "fsl,qe-ic". Unfortunately it's still impossible to remove device_type = "qe" from the existing device trees because older u-boots are looking for it.

2008-01-28[POWERPC] 83xx: mpc834x_mds - Convert device tree source to dts-v1Paul Gortmaker1-125/+127
Move mpc834x_mds device tree source forward to dts-v1 format. Nothing too complex in this one, so it boils down to just adding a bunch of 0x in the right places and converting clock speeds to decimal.

This adds the device tree source for the Wind River SBC834x board. It is based on the MPC834x_MDS DTS, with the biggest difference being the lack of BCSR and the PCI2 that the MDS gets via the PIB.

2008-01-28[POWERPC] Reduce code duplication in legacy_serial, add UART parent typesPaul Gortmaker1-28/+17
The legacy_serial was treating each UART parent in a separate code block. Rather than continue this trend for the new parent IDs, this condenses all (soc, tsi, opb, plus two more new types) into one of_device_id array.

2008-01-26Revert "[POWERPC] Fake NUMA emulation for PowerPC"Paul Mackerras1-54/+5
This reverts commit 5c3f5892a2db6757a72ce8b27cba90db06683e1d, basically because it changes behaviour even when no fake NUMA information is specified on the kernel command line. Firstly, it changes the nid, thus destroying the real NUMA information. Secondly, it also changes behaviour in that if a node ends up with no memory in it because of the memory limit, we used to set it online and now we don't. Also, in the non-NUMA case with no fake NUMA information, we do node_set_online once for each LMB now, whereas previously we only did it once. I don't know if that is actually a problem, but it does seem unnecessary. Signed-off-by: Paul Mackerras <paulus@samba.org>

2008-01-25[POWERPC] Enable RTC for Ebony and Walnut (v2)David Gibson9-4/+78
This patch extends the Ebony and Walnut platform code to instantiate the existing ds1742 RTC class driver for the DS1743 RTC/NVRAM chip found on both those boards. The patch uses a helper function to scan the device tree and instantiate the appropriate platform_device based on it, so it should be easy to extend for other boards which have mmio mapped RTC chips. Along with this, the device tree binding for the ds1743 chips is tweaked, based on the existing DS1385 OF binding found at: http://playground.sun.com/1275/proposals/Closed/Remanded/Accepted/346-it.txt Although that document covers the NVRAM portion of the chip, whereas here we're interested in the RTC portion, so it's not entirely clear if that's a good model. This implements only RTC class driver support - that is /dev/rtc0, not /dev/rtc, and the low-level get/set time callbacks remain unimplemented. That means in order to get at the clock you will either need a modified version of hwclock which will look at /dev/rtc0, or you'll need to configure udev to symlink rtc0 to rtc.
