2014-09-09mmc: tmio-mmc: Add support for SDHI on new R-Car Gen2 SoCsGeert Uytterhoeven1-0/+3

2014-09-09mmc: implement Driver Stage Register handlingSascha Hauer1-0/+2
Some eMMC and SD cards implement a DSR register that allows to tune raise/fall times and drive strength of the CMD and DATA outputs. The values to use depend on the card in use and the host. It might be needed to reduce the drive strength to prevent voltage peaks above the host's specification. Implement a 'dsr' devicetree property that allows to specify the value to set the DSR to. For non-dt setups the new members of mmc_host can be set by board code. This patch was initially authored by Sascha Hauer. It contains improvements authored by Markus Niebel and Uwe Kleine-König.

This defines the device tree bindings for the Toshiba TC3589x series of multi-purpose expanders. Only the stuff I can test is defined: GPIO and keypad. Others may implement more subdevices further down the road.

2014-08-26ARM: OMAP2+: GPMC: Support Software ECC scheme via DTRoger Quadros1-1/+1
For v3.14 and prior, 1-bit Hamming code ECC via software was the default choice for some boards e.g. 3430sdp. Commit ac65caf514ec in v3.15 changed the behaviour to use 1-bit Hamming code via Hardware using a different ECC layout i.e. (ROM code layout) than what is used by software ECC. This ECC layout change causes NAND filesystems created in v3.14 and prior to be unusable in v3.15 and later. So don't mark "sw" scheme as deperecated and support it.

2014-08-16of/irq: Fix lookup to use 'interrupts-extended' property firstFlorian Fainelli1-5/+7
In case the Device Tree blob passed by the boot agent supplies both an 'interrupts-extended' and an 'interrupts' property in order to allow for older kernels to be usable, prefer the new-style 'interrupts-extended' property which conveys a lot more information. This allows us to have bootloaders willingly maintaining backwards compatibility with older kernels without entirely deprecating the 'interrupts' property. Update the bindings documentation to describe a situation where both the 'interrupts-extended' and the 'interrupts' property are present, and which one takes precedence over the other.

Pull device tree updates from Grant Likely: "The branch contains the following device tree changes the v3.17 merge window: Group changes to the device tree. In preparation for adding device tree overlay support, OF_DYNAMIC is reworked so that a set of device tree changes can be prepared and applied to the tree all at once. OF_RECONFIG notifiers see the most significant change here so that users always get a consistent view of the tree. Notifiers generation is moved from before a change to after it, and notifiers for a group of changes are emitted after the entire block of changes have been applied Automatic console selection from DT. Console drivers can now use of_console_check() to see if the device node is specified as a console device. If so then it gets added as a preferred console. UART devices get this support automatically when uart_add_one_port() is called. DT unit tests no longer depend on pre-loaded data in the device tree. Data is loaded dynamically at the start of unit tests, and then unloaded again when the tests have completed.
