| * [POWERPC] mpc52xx_psc_spi device driver must not touch port_config and cdmGrant Likely2008-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | It is dangerous for an mpc52xx device driver to modify the port_config register. If the driver is probed incorrectly, it will change the pin IO configuration in ways which may not be compatible with the board. port_config should be set up by the bootloader, or failing that, in the platform setup code in arch/powerpc/platforms/52xx. Also, modifying CDM registers directly can cause a race condition with other drivers. Instead call a common routine to modify CDM settings.

| * [POWERPC] Add common clock setting routine mpc52xx_psc_set_clkdiv()Grant Likely2008-01-26
| | | | | | | | | | | | | | | | PSC drivers should not access the CDM registers directly. Instead provide a common routine for setting the PSC clock parameters with the required locking. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
| * [POWERPC] Efika: prune fixups and make them more carefullGrant Likely2008-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Prune back Efika fixups to only include changes that are actually required to get a working system. Most of the drivers can accept the compatible properties, even if they don't match the what is recommented in the generic names recommended practice document. This patch also adds extra checks so that fixups are not performed blindly. Instead, the code first verifies that the device tree is faulty before making any changes. This way, if the Efika firmware is updated to fix these issues, then the fixups will no longer get applied. At this point; here is the list of fixups needed for the efika: 1. If the device_type property on the root node is 'chrp', then Linux won't boot. Change device_type to 'efika' to avoid this condition 2. Add full interrupt list to the bestcomm node. In actual fact, the bestcomm interrupts property is technically correct, it just doesn't expose the same granularity as the device driver expects. All other 5200 device trees provide a separate irq number for each bestcomm channel. Rather than hack the driver, it's simpler to fix it up 3. /builtin/sound node is missing an interrupts property 4. /builtin/ethernet node is missing a phy-handle property and the device driver doesn't know what to do without one.

| * [POWERPC] mpc5200: normalize compatible property bindingsGrant Likely2008-01-26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Update MPC5200 drivers to also look for compatible properties in the form "fsl,mpc5200-*" to better conform to open firmware generic names recommended practice as published here: http://www.openfirmware.org/1275/practice/gnames/gnamv14a.html This patch should *not* break compatibility with older device trees which do not use the 'fsl,' prefix. The drivers will still bind against the older names also. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>

| | | | | | | | | | | | | | | | | | | | The various 5200 dts files don't have values specified for the soc node, which in turn results in a warning from the processing of every child node (roughly 40 warnings per file).

* | [POWERPC] 83xx: Clean up / convert mpc83xx board DTS files to v1 format.Paul Gortmaker2008-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch converts the remaining 83xx boards to the dts-v1 format. This includes the mpc8313_rdb, mpc832x_mds, mpc8323_rdb, mpc8349emitx, mpc8349emitxgp and the mpc836x_mds. The mpc8315_rdb mpc834x_mds, mpc837[789]_*, and sbc8349 were already dts-v1 and only undergo minor changes for the sake of formatting consistency across the whole group of boards; i.e. the idea being that you can do a "diff -u board_A.dts board_B.dts" and see something meaningful. The general rule I've applied is that entries for values normally parsed by humans are left in decimal (i.e. IRQ, cache size, clock rates, basic counts and indexes) and all other data (i.e. reg and ranges, IRQ flags etc.) remain in hex. I've used dtc to confirm that the output prior to this changeset matches the output after this changeset is applied for all boards.

* | [POWERPC] QE: Explicitly set address-cells and size cells for muramPaul Gortmaker2008-01-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently there are several dts that don't specify address or size cells for the muram. This causes dtc to use default values, one of which is an address-cells of two, and this breaks the parsing of the muram ranges, which is assuming an address-cells of one. For example: Warning (reg_format): "reg" property in /qe@e0100000/muram@10000/data-only@0 has invalid length (8 bytes) (#address-cells == 2, #size-cells == 1) Explicitly setting the address and size cells gets it parsed properly and gets rid of the four dtc warnings.
