* ARM: u300: Convert to the common mmc DT bindings for highspeed modeUlf Hansson2014-05-121-2/+2
| | | | | | | | The mmci host driver supports the common mmc DT parser, which enables us to use the use common names instead. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org> Acked-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: u300: switch SSP/SPI clock name to "SSPCLK"Linus Walleij2014-02-261-1/+1
| | | | | | | | | | | As noted in recent discussions the name of the core clock for the PL022 derived SPI blocks is erroneously named in the U300 device tree. The kernel doesn't currently use the name, but may do so soon so let use rename all these clocks in accordance with the name given in the PL022 TRM (ARM DDI 0194G).

* ARM: u300: switch to using syscon regmap for boardLinus Walleij2013-06-171-1/+1
| | | | | | | | | | | | | | This switches the code using a local remapping of the system controller to enable the U300 board to be self-powered over to making the U300-specific syscon compatible with the MFD generic syscon driver, selecting the generic syscon driver, and augmenting the board power code to pick the regmap and manipulate the syscon from the regmap side of things.

* ARM: u300: convert MMC/SD clock to device treeLinus Walleij2013-06-171-2/+7
| | | | | | | | This converts the last of the U300 clocks to being probed from the device tree. Acked-by: Mike Turquette <mturquette@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: u300: move the gated system controller clocks to DTLinus Walleij2013-06-171-0/+149
| | | | | | | | | This moves the slow, fast, AHB bridge and "rest" clocks on the U300 system controller over to registration from the device tree. Acked-by: Mike Turquette <mturquette@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* clk: move the U300 fixed and fixed-factor to DTLinus Walleij2013-06-171-0/+44
| | | | | | | | This converts the fixed and fixed-factor clocks in the U300 platform to register themselves from the device tree. Acked-by: Mike Turquette <mturquette@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: u300: add syscon nodeLinus Walleij2013-06-171-0/+6
| | | | | | | | | | | This adds a device tree node for the U300 system controller and remaps this dynamically instead of using hard-coded virtual addresses. The board power set-up code is altered to fetch a reference to the syscon using ampersand <&syscon> notation. This way of passing a pointer to the syscon will also be used by the clocks.

* ARM: u300: add FSMC flash into the device treeLinus Walleij2013-06-171-0/+26
| | | | | | | | This registers the U300 FSMC flash controller from the device tree, and defines the three partitions. Skip the BBT scan as in the current platform data. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: u300: probe the U300 dummy-spichip from device treeLinus Walleij2013-06-171-0/+5
| | | | | | | This probes the U300 dummy-spichip from the device tree and adds the apropriate node to the tree. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: u300: add SPI PL022 to the device treeLinus Walleij2013-06-171-0/+12
| | | | | | | | | This registers the PL022 PrimeCell from the U300 device tree. We make a new copy of the platform data for the device tree boot path, as the old platform data is in an older file which will be going away. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: u300: add the COH 901 318 DMAC to device treeLinus Walleij2013-06-171-0/+9
| | | | | | | | | | | This adds the COH 901 318 DMA controller to the U300 device tree. All devices now converted to device tree so far will start to find their DMA channels. Note that the U300 is not yet using the device tree to obtain DMA channels, but this is a first step. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: u300: augment device tree with DMA channelsLinus Walleij2013-06-171-0/+6
| | | | | | | | | This adds DMA channel assignments to the MMC/SD-controller and the two UARTs already in the U300 device tree, as we have now defined a way to obtain DMA channels from the device tree. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: u300: enable MMC/SD card from device treeLinus Walleij2013-06-171-0/+14
| | | | | | | This adds support for the U300 MMC/SD card slot from the device tree boot. No other changes needed. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: u300: support regulators in the device treeLinus Walleij2013-06-171-0/+79
| | | | | | | | | | Now that we have enabled board power and the AB3100 regulators, put the regulator data into the device tree and enable it so we can start to tie regulators to devices. To begin with we're only supplying the power to the board itself. Cc: Mark Brown <broonie@kernel.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: u300: add RTC to device treeLinus Walleij2013-06-171-0/+7
| | | | | | This adds the COH 901 331 RTC to the U300 device tree. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
* ARM: u300: add the COH 901 327 watchdog to device treeLinus Walleij2013-05-311-0/+7

* ARM: u300: register I2C bus drivers from device treeLinus Walleij2013-05-311-0/+18
| | | | | | | This adds the two I2C busses to the device tree so these probe properly. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>

This register the most basic peripherals and makes the U300 boot to prompt from a device tree. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
