2008-12-15powerpc/85xx: Fix compile issues with mpc8572ds.dtsKumar Gala
Fix the localbus reg & range properties to respect that the top level #address-cells and #size-cells = 2. The original commit (c64ef80b517680f1e228b2ee55e3ce7cd94c7fe0) did not do that. Signed-off-by: Kumar Gala <galak@kernel.crashing.org>
2008-12-11powerpc/4xx: Add L2 cache node to AMCC Canyonlands dts fileStefan Roese
With this patch the L2 cache is enabled on Canyonlands to increase the overall performance. There is a known cache coherency issue with the L2 cache, but this is related to the high bandwidth (HB) PLB segment where the memory address is 0x8.xxxx.xxxx (low bandwidth PLB segment is mapped to 0x0.xxxx.xxxx). Since this HB address is currently unused it is safe to enable the L2 cache. Signed-off-by: Stefan Roese <sr@denx.de> Signed-off-by: Josh Boyer <jwboyer@linux.vnet.ibm.com>
2008-12-04powerpc/4xx: Add support for ISA holes on 4xx PCI/X/EBenjamin Herrenschmidt
This adds support for ISA memory holes on the PCI, PCI-X and PCI-E busses of the 4xx platforms. The patch includes changes to the Bamboo and Canyonlands device-trees to add such a hole, others can be updated separately. The ISA memory hole is an additional outbound window configured in the bridge to generate PCI cycles in the low memory addresses, thus allowing to access things such as the hard-decoded VGA aperture at 0xa0000..0xbffff or other similar things. It's made accessible to userspace via the new legacy_mem file in sysfs for which support was added by a previous patch.

2008-12-03powerpc/85xx: Create dts for each core in CAMP mode for MPC8572DSHaiying Wang
This patch creates the dts files for each core and splits the devices between the two cores for MPC8572DS. core0 has memory, L2, i2c, dma1, global-util, eth0, eth1, crypto, pci0, pci1. core1 has L2, dma2, eth2, eth3, pci2, msi. MPIC is shared between two cores but each core will protect its interrupts from other core by using "protected-sources" of mpic.

2008-12-03powerpc/86xx: Basic GPIO support for GE Fanuc SBC610Martyn Welch
Basic support for the GPIO available on the SBC610 VPX Single Board Computer from GE Fanuc (PowerPC MPC8641D). This patch adds basic support for the GPIO in the devices I/O FPGA, the GPIO functionality is exposed through the AFIX pins on the backplane, unless used by an AFIX card. This code currently does not support switching between totem-pole and open-drain outputs (when used as outputs, GPIOs default to totem-pole).

2008-12-03powerpc/83xx: Fix MCU support merge issue in mpc8349emitx.dtsAnton Vorontsov
Just found the merge issue in 442746989d92afc125040e0f29b33602ad94da99 ("powerpc/83xx: Add support for MCU microcontroller in .dts files"): the commit adds the MCU controller node into the DMA node, which is wrong because the MCU sits on the I2C bus. Fix this by moving the MCU node into the I2C controller node. The original patch[1] was OK though. ;-) Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2008-10-13powerpc: reserve two DMA channels for audio in MPC8610 HPCD device treeTimur Tabi
The Freescale Elo DMA driver binds to all DMA channels in the device tree that are compatible with "fsl,eloplus-dma-channel". This conflicts with the sound drivers for the MPC8610 HPCD. On this board, the SSI uses two DMA channels and therefore those channels are not available for general purpose use. We change the compatible properties for these channels "fsl,ssi-dma-channel". This works because the sound drivers don't actually check the compatible property when it grabs channels.

Modify mpc83xx_add_bridge to get config space register base address from the device tree instead of immr + hardcoded offset. 83xx pci nodes have this change: register properties now contain two address length tuples: First is the pci bridge register base, this has always been there. Second is the config base, this is new. This is documented in dts-bindings/fsl/83xx-512x-pci.txt The changes accomplish these things: mpc83xx_add_bridge no longer needs to call get_immrbase it uses hard coded addresses if the second register value is missing Signed-off-by: John Rigby <jrigby@freescale.com> Signed-off-by: Kumar Gala <galak@kernel.crashing.org>

2008-09-30powerpc: Fix PCI in Holly device treeDavid Gibson
The PCI bridge on the Holly board is incorrectly represented in the device tree. The current device tree node for the PCI bridge sits under the tsi-bridge node. That's not obviously wrong, but the PCI bridge translates some PCI spaces into CPU address ranges which were not translated by the "ranges" property in tsi-bridge node. We used to get away with this problem because the PCI bridge discovery code was also buggy, assuming incorrectly that PCI host bridge nodes were always directly under the root bus and treating the translated addresses as raw CPU addresses, rather than parent bus addresses. This has since been fixed, thus breaking Holly. This could be fixed by adding extra translations to the tsi-bridge node, but this patch instead moves the Holly PCI bridge out of the tsi-bridge node to the root bus. This makes the tsi-bridge node represent only the built-in IO devices in the bridge, with a more-or-less contiguous address range. This is the same convention used on Freescale SoC chips, where the "soc" node represents only the IMMR region, and the PCI and other bus bridges are separate nodes under the root bus.

2008-09-16powerpc: Fix interrupt values for DMA2 in MPC8610 HPCD device treeTimur Tabi
For Freescale 8xxx devices that use an MPIC, the interrupt numbers in the device tree must be 16 greater than the values documented in the reference manual. In these chips, the MPIC is wired to use the first 16 numbers for external interrupts, but the documentation numbers internal interrupts from 0. In the MPC8610 HPCD device tree, the interrupt properties for the DMA channels for DMA2 were not the adjusted values. This fixes that.
