* [ARM] pass reboot command line to arch_reset()Russell King2009-03-191-1/+1
| | | | | | | | | | | | | | | OMAP wishes to pass state to the boot loader upon reboot in order to instruct it whether to wait for USB-based reflashing or not. There is already a facility to do this via the reboot() syscall, except we ignore the string passed to machine_restart(). This patch fixes things to pass this string to arch_reset(). This means that we keep the reboot mode limited to telling the kernel _how_ to perform the reboot which should be independent of what we request the boot loader to do.

The gpio kernel lib is also called when a capable gpio pin is assigned its gpio function. The mxc_iomux_mode function is still here for backward compatibility but should not be used anymore. V2: In the precendent revision, the iomux code was claiming a pin when its hardware mode was changed. This was uncorrect: when the hardware mode is changed, the pin must still be claimed through the iomux. In order to have a pin working in mode hw2, we must fist issue the mxc_iomux_set_gpr call and then the corresponding mxc_iomux_mode calls with the FUNC mode (usually done with mxc_iomux_setup_multiple_pins). The reverse calls must be done to fee the pins. Signed-off-by: Valentin Longchamp <valentin.longchamp@epfl.ch> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i.MX3x SoCs contain an Image Processing Unit, consisting of a Control Module (CM), Display Interface (DI), Synchronous Display Controller (SDC), Asynchronous Display Controller (ADC), Image Converter (IC), Post-Filter (PF), Camera Sensor Interface (CSI), and an Image DMA Controller (IDMAC). CM contains, among other blocks, an Interrupt Generator (IG) and a Clock and Reset Control Unit (CRCU). This driver serves IDMAC and IG. They are supported over dmaengine and irq-chip APIs respectively. IDMAC is a specialised DMA controller, its DMA channels cannot be used for general-purpose operations, even though it might be possible to configure a memory-to-memory channel for memcpy operation. This driver will not work with generic dmaengine clients, clients, wishing to use it must use respective wrapper structures, they also must specify which channels they require, as channels are hard-wired to specific IPU functions.
