Revert "drivers: of: add initialization code for dma reserved memory"

2013-10-15T08:26:07Z

This reverts commit 9d8eab7af79cb4ce2de5de39f82c455b1f796963. There is still no consensus on the bindings for the reserved memory and various drawbacks of the proposed solution has been shown, so the best now is to revert it completely and start again from scratch later.

drivers: of: add initialization code for dma reserved memory

2013-08-27T08:53:44Z

This patch adds device tree support for contiguous and reserved memory regions defined in device tree. Large memory blocks can be reliably reserved only during early boot. This must happen before the whole memory management subsystem is initialized, because we need to ensure that the given contiguous blocks are not yet allocated by kernel. Also it must happen before kernel mappings for the whole low memory are created, to ensure that there will be no mappings (for reserved blocks) or mapping with special properties can be created (for CMA blocks). This all happens before device tree structures are unflattened, so we need to get reserved memory layout directly from fdt. Later, those reserved memory regions are assigned to devices on each device structure initialization.

i2c: move OF helpers into the core

2013-08-23T08:22:20Z

I2C of helpers used to live in of_i2c.c but experience (from SPI) shows that it is much cleaner to have this in the core. This also removes a circular dependency between the helpers and the core, and so we can finally register child nodes in the core instead of doing this manually in each driver. So, fix the drivers and documentation, too. Signed-off-by: Wolfram Sang

of: remove CONFIG_OF_DEVICE

2013-06-12T11:37:40Z

CONFIG_OF_DEVICE is always selected when CONFIG_OF is enabled, so remove it and simplify of_platform.h and of_device.h headers. This also fixes !OF compiles using of_platform_populate. Signed-off-by: Rob Herring Acked-by: Arnd Bergmann Tested-by: Benjamin Herrenschmidt Signed-off-by: Grant Likely

Pull GPIO driver changes from Grant Likely: "Lots of gpio changes, both to core code and drivers. Changes do touch architecture code to remove the need for separate arm/gpio.h includes in most architectures. Some new drivers are added, and a number of gpio drivers are converted to use irq_domains for gpio inputs used as interrupts. Device tree support has been amended to allow multiple gpio_chips to use the same device tree node. Remaining changes are primarily bug fixes." * tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux-2.6: (33 commits) gpio/generic: initialize basic_mmio_gpio shadow variables properly gpiolib: Remove 'const' from data argument of gpiochip_find() gpio/rc5t583: add gpio driver for RICOH PMIC RC5T583 gpiolib: quiet gpiochip_add boot message noise gpio: mpc8xxx: Prevent NULL pointer deref in demux handler gpio/lpc32xx: Add device tree support gpio: Adjust of_xlate API to support multiple GPIO chips gpiolib: Implement devm_gpio_request_one() gpio-mcp23s08: dbg_show: fix pullup configuration display Add support for TCA6424A gpio/omap: (re)fix wakeups on level-triggered GPIOs gpio/omap: fix broken context restore for non-OFF mode transitions gpio/omap: fix missing check in *_runtime_suspend() gpio/omap: remove cpu_is_omapxxxx() checks from *_runtime_resume() gpio/omap: remove suspend/resume callbacks gpio/omap: remove retrigger variable in gpio_irq_handler gpio/omap: remove saved_wakeup field from struct gpio_bank gpio/omap: remove suspend_wakeup field from struct gpio_bank gpio/omap: remove saved_fallingdetect, saved_risingdetect gpio/omap: remove virtual_irq_start variable ...

spi/devicetree: Move devicetree support code into spi directory

2012-04-13T16:21:39Z

The SPI device tree support code isn't shared by any other subsystem. It can be moved into the core drivers/spi directory and the exported symbol can be removed. Signed-off-by: Grant Likely Cc: Rob Herring

gpio: Move DT support code into drivers/gpio

2012-04-07T20:35:28Z

The code in drivers/of/gpio.c isn't shared by any other subsystem since it is all gpiolib specific. drivers/gpio is a better place to maintain these functions. Signed-off-by: Grant Likely Cc: Rob Herring Cc: Linus Walleij
