2009-03-13[ARM] MXC: add clkdev supportSascha Hauer
This patch only adds general clkdev support without actually switching any MXC architecture to clkdev. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2009-03-13[ARM] MXC: remove _clk suffix from clock namesSascha Hauer
The context makes it clear already that these are clocks, so there's no need for such a suffix. This patch only changes the clocks actually used in the tree. The remaining clocks are renamed in the subsequent architecture specific patches. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2009-03-13[ARM] MXC: rework timer/clock initialisationSascha Hauer
- rename mxc_clocks_init to architecture specific versions. This allows us to have more than one architecture compiled in. - call mxc_timer_init from clock initialisation instead from board code Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2009-03-13[ARM] MXC: Use a single function for decoding a PLLSascha Hauer
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. This patch has been tested on MX27 and MX31 and produces the same clock frequencies for me.

2009-03-13arm/imx21: add kbuild support for the Freescale i.MX21Holger Schurig
* adds Kconfig variables * specifies different physical address for i.MX21 because of the different memory layouts * disables support for UART5/UART6 in the i.MX serial driver (the i.MX21 doesn't have those modules) Based on code from "Martin Fuzzey" <mfuzzey@gmail.com> Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2009-03-13arm/imx2x: new IOMUX definitionsHolger Schurig
* removed iomux-mx1-mx2.h completely * distributes the former contents to four different files (iomux-mx1.h, iomux-mx21.h, iomux-mx27.h and the file iomux-mx2x.h, which is common to both i.MX21 and i.MX27). * adds all documented IOMUX definitions for i.MX21 and i.MX27 * fixes a few that were wrong (PD14_AOUT_FEC_CLR, PE16_AF_RTCK). * don't silenly include <linux/io.h> * and fixes all collateral damage from above Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

2009-02-02mmc: Add a MX2/MX3 specific SDHC driverSascha Hauer
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. Since the MX1 driver has more workarounds for bugs than anything else I had no success with supporting MX1 and MX2 in a sane way in one driver.

2009-01-19i.MX31: Image Processing Unit DMA and IRQ driversGuennadi Liakhovetski
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.

2008-11-30[ARM] Add a common typesafe __io implementationRussell King

2008-11-29[ARM] Hide ISA DMA API when ISA_DMA_API is unsetRussell King
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.

2008-11-28[ARM] remove a common set of __virt_to_bus definitionsNicolas Pitre
Let's provide an overridable default instead of having every machine class define __virt_to_bus and __bus_to_virt to the same thing. 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.
