* mxc: add arch_reset() functionIlya Yanok2009-03-27
| | | | | | | | | | | This patch adds arch_reset() function for all mxc platforms. It also removes (unsused) arch/arm/mach-mx2/system.c file. This patch has been tested on i.MX1/27/31/35 Signed-off-by: Ilya Yanok <yanok@emcraft.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* [ARM] pass reboot command line to arch_reset()Russell King2009-03-19
| | | | | | | | | | | | | | | 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.

* | [ARM] MX35: add clock supportSascha Hauer2009-03-13
| | | | | | | | | | | | | | | | | | This patch adds clock support for i.MX35 SoCs. We do not support setting of clock rates yet, but most interesting clock rates should be reported. I couldn't test all clock rates and the datasheet contains some obvious bugs, so expect some bugs in this code. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | [ARM] MXC: add cpu_is_ macrosSascha Hauer2009-03-13
| | | | | | | | | | | | | | | | | | | | We had hardcoded cpu_is_ macros for mxc architectures till now. As we want to run the same kernel on i.MX31 and i.MX35 this patch adds cpu_is_ macros which expand to 0 or 1 if only one architecture is compiled in and only check for the cpu type if more than one architecture is compiled in.

* | mx31: rework of iomux supportValentin Longchamp2009-03-13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This new implemenatation avoids that two physical pins are claimed by the same driver (also with the the gpr hardware modes). 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>

| | | | | | | | | | | | | | | | | | | | | | | | We had 3 versions of this function in clock support for MX1/2/3 Use a single one instead. I picked the one from the MX3 as it seems to calculate more accurate as the other ones. Also, on MX27 and MX31 mfn can be negative, this hasn't been handled correctly on MX27 since now.

* mmc: Add a MX2/MX3 specific SDHC driverSascha Hauer2009-02-02
| | | | | | | | | | | This patch adds a MX2/MX3 specific SDHC driver. The hardware is basically the same as in the MX1, but unlike the MX1 controller the MX2 controller just works as expected.

* i.MX31: Image Processing Unit DMA and IRQ driversGuennadi Liakhovetski2009-01-19
| | | | | | | | | | | | | | | | | | | | | | 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.

* [ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King2008-11-29
| | | | | | | | | | | | | When ISA_DMA_API is unset, we're not implementing the ISA DMA API, so there's no point in publishing the prototypes via asm/dma.h, nor including the machine dependent parts of that API. This allows us to remove a lot of mach/dma.h files which don't contain any useful code. Unfortunately though, some platforms put their own private non-ISA definitions into mach/dma.h, so we leave these behind and fix the appropriate #include statments.

What most platforms are using is bus_addr == phys_addr so such is the default. One exception is ebsa110 which has no DMA what so ever, so the actual definition is not important except only for proper compilation. Also added a comment about the special footbridge bus translation. Let's also remove comments alluding to set_dma_addr which is not (and should not) be commonly used.
