2009-09-23powerpc: introduce and document sdhci,wp-inverted property for eSDHCAnton Vorontsov
eSDHC block in MPC837x SOCs reports inverted write-protect state, soon sdhci-of driver will look for sdhci,wp-inverted properties to decide whether apply a specific quirk. So, document the property and add it to device tree source files.

2009-06-21sdhci: Add support for hosts that are only capable of 1-bit transfersAnton Vorontsov
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.

2009-05-19powerpc/qe: update QE Serial NumberHaiying Wang
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.

Stashing is only supported on the 85xx (e500-based) SoCs. The 83xx and 86xx chips don't have a proper cache for this. U-Boot has been updated to add stashing properties to the device tree nodes of gianfar devices on 85xx. So now we modify Linux to keep stashing off unless those properties are there.

2008-12-30powerpc: Add device tree bindings for BCSR GPIO banksAnton Vorontsov
The patch adds bindings for BCSR GPIO banks, the bindings are used to describe particular BCSR registers that act as simple GPIO controllers.

2008-10-13powerpc: document the "fsl,ssi-dma-channel" compatible propertyTimur Tabi
The "fsl,ssi-dma-channel" compatible property is used to specify a DMA channel on the Freescale Elo DMA controller that should be used exclusively by the Freescale SSI audio controller. When a property is marked as such, the Elo DMA driver will ignore it, and so it will be available for the sound drivers.

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>
