2013-06-17ARM: u300: add syscon nodeLinus Walleij
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.

2013-06-17ARM: u300 use module_spi_driver to register driverPeter Huewe
Removing some boilerplate by using module_spi_driver instead of calling register and unregister in the otherwise empty init/exit functions. Signed-off-by: Peter Huewe <peterhuewe@gmx.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-06-17ARM: u300: delete remnant machine headersLinus Walleij
Two files remain in <mach/*> for U300: timex.h and uncompress.h. The former is done away with by using defaults, the latter is unused in multiplatform. Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-06-17ARM: u300: convert to multiplatformLinus Walleij
Now that we removed our dependency on <mach/*> the U300 can be converted to mutliplatform. Remove the invalid restriction that U300 would not support AUTO_ZRELADDR (it does) and update the defconfig in the process. Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-06-17ARM: u300: localize <mach/u300-regs.h>Linus Walleij
This register base file is now only used in the machine itself so move it down into mach-u300. Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-06-17ARM: u300: delete <mach/irqs.h>Linus Walleij
All IRQs are now obtained from the device tree, and this file is unused, so delete it. Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-06-17ARM: u300: delete <mach/hardware.h>Linus Walleij
This file is now unused and can be deleted. Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-06-17ARM: u300: push down syscon registersLinus Walleij
Get rid of the <mach/syscon.h> header as a prerequisite for multiplatform support. Do this by pushing the registers down to their respective drivers and deleting the unused remainder. Acked-by: Mike Turquette <mturquette@linaro.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-06-17ARM: u300: remove deps from debug macroLinus Walleij
This rids the dependency to <mach/hardware.h> (which is an implicit dependency to <mach/u300-regs.h>) from the U300 debug macro. Take this opportunity to update the file header. Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-06-17ARM: u300: move debugmacro to debug includesLinus Walleij
This moves the U300 debug macro to the debug headers to make way for multiplatform support. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-06-17ARM: u300: delete all static board dataLinus Walleij
We have now transferred all the U300 peripherals to the device tree, so we just select USE_OF, and delete all static board data, then require that this platform shall be booted using the device tree and nothing else. This gets rid of the MMCI (PL180), PL022, and serial PL011 platform data entries and more. Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-06-17ARM: u300: add FSMC flash into the device treeLinus Walleij
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>
2013-06-17ARM: u300: probe the U300 dummy-spichip from device treeLinus Walleij
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>
2013-06-17ARM: u300: add SPI PL022 to the device treeLinus Walleij
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>
2013-06-17ARM: u300: add the COH 901 318 DMAC to device treeLinus Walleij
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>
2013-06-17ARM: u300: augment device tree with DMA channelsLinus Walleij
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>
2013-06-17ARM: u300: enable MMC/SD card from device treeLinus Walleij
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>
2013-06-17ARM: u300: support regulators in the device treeLinus Walleij
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>
2013-06-17ARM: u300: set up board power from device treeLinus Walleij
This adds support for setting up the board power from the device tree on the U300. We use a board-specific node in the device tree for the S365 board and bind a regulator for the board power to this node. Cc: Mark Brown <broonie@kernel.org> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
2013-06-17ARM: u300: add RTC to device treeLinus Walleij

2013-06-17ARM: 7755/1: handle user space mapped pages in flush_kernel_dcache_pageSimon Baatz
Commit f8b63c1 made flush_kernel_dcache_page a no-op assuming that the pages it needs to handle are kernel mapped only. However, for example when doing direct I/O, pages with user space mappings may occur. Thus, continue to do lazy flushing if there are no user space mappings. Otherwise, flush the kernel cache lines directly.

2013-06-17ARM: 7752/1: errata: LoUIS bit field in CLIDR register is incorrectJon Medhurst
On Cortex-A9 before version r1p0, the LoUIS bit field of the CLIDR register returns zero when it should return one. This leads to cache maintenance operations which rely on this value to not function as intended, causing data corruption. The workaround for this errata is to detect affected CPUs and correct the LoUIS value read.
