* arm/imx/iomux-v1: rename source file and reorganize Kconfig stuffUwe Kleine-König2010-02-24
| | | | Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/imx/dma-v1: protect #ifdef'd blocks additionally by cpu_is_...Uwe Kleine-König2010-02-24
| | | | | | This is necessary for a multi-SoC kernel. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/imx/dma-v1: don't use deprecated symbols DMA_BASE and MXC_INT_DMACH0Uwe Kleine-König2010-02-24

* arm/imx: choose sane CONSISTENT_DMA_SIZE if video is enabled for both mx1 ↵Uwe Kleine-König2010-02-24
| | | | | | and mx3 Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/imx/irq: order definitions of MXC_GPIO_IRQS numericallyUwe Kleine-König2010-02-24
| | | | | | This is important for kernels supporting more than one SoC. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/imx: don't depend on ARCH_MXC twiceUwe Kleine-König2010-02-24
| | | | | | | MXC_IRQ_PRIOR, MXC_PWM and ARCH_HAS_RNGA are all defined in an "if ARCH_MXC" ... "endif" block, so they depend on ARCH_MXC anyhow. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/imx: remove #ifndef CONFIG_COMMON_CLKDEV blockUwe Kleine-König2010-02-24
| | | | | | COMMON_CLKDEV is used on all imx platforms, so this isn't used. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/imx: remove MTD_XIP supportUwe Kleine-König2010-02-24
| | | | | | | | | | This is broken since at least one year when ec996ba (mxc timer: make compile time independent) removed the symbol MXC_TCN. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/imx: don't explicitly select GENERIC_GPIOUwe Kleine-König2010-02-24
| | | | | | ARCH_REQUIRE_GPIOLIB selects GPIOLIB which in turn selects GENERIC_GPIO Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/imx: let ARCH_MXC select COMMON_CLKDEV instead of each subfamilyUwe Kleine-König2010-02-24
| | | | Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/imx: remove "NO_PAD_CTRL" from Copyright statementsUwe Kleine-König2010-02-24
| | | | | | | | I assume this was introduced by something like sed -i -e 's/)/, NO_PAD_CTRL)' Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

| | | | Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/imx/gpio: remove a BUG_ON in hot pathUwe Kleine-König2010-02-24
| | | | | | | | Now if the problem occurs that triggered the BUG_ON before, the machine runs in a NULL pointer dereference. So it wouldn't be much harder now to debug the situation if it occured. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/imx/gpio: use fls to find set bits in the irq status registerUwe Kleine-König2010-02-24
| | | | | | | As in most cases only few irqs are pending using fls is more effective than looping over all bits. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/imx: use generic_handle_irq instead of open-coding itUwe Kleine-König2010-02-24
| | | | Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/imx/gpio: GPIO_INT_{HIGH,LOW}_LEV are not necessarily constantUwe Kleine-König2010-02-24
| | | | | | | | | | | | GPIO_INT_LOW_LEV is defined as (cpu_is_mx1_mx2() ? 0x3 : 0x0) so depending on compiler optimisation and enabled SoCs this doesn't qualify as a constant expression as needed by a switch statement. Ditto for GPIO_INT_HIGH_LEV. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/mx2: split generic.c into mm-imx2[17].cUwe Kleine-König2010-02-24
| | | | | | | This removes some #ifdefs and prepares moving the files in a directory with more than imx21 and imx27 support. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/mx2/devices: no need for IMX_NEEDS_DEPRECATED_SYMBOLS any moreUwe Kleine-König2010-02-24
| | | | | | | The previous commits cleaned up arch/arm/mach-mx2/devices.c such that it doesn't rely on deprecated symbols any more. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/mx2: define seperate gpio port descriptions for imx21 and imx27Uwe Kleine-König2010-02-24
| | | | | | | | | As the gpio ports have different addresses on imx21 and imx27 there are two different port descriptions needed if not relying on the overloaded cpp macro IO_ADDRESS. So some cpp magic is added to minimize code duplication. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/mx2: use per-SOC nand deviceUwe Kleine-König2010-02-24
| | | | | | | | | The previous commit introduced one nand device per SoC. Use this directly instead of the compatibility macro that will break for multi-SoC kernels. And while at it remove the compatibility macro now that all in-tree users are fixed. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/mx2: define seperate imx_nand devices for imx21 and imx27Uwe Kleine-König2010-02-15
| | | | | | | | | | | | | As the NFC controller has different addresses on imx21 and imx27 there are two different devices needed if not relying on the overloaded cpp macro NFC_BASE_ADDR. So some cpp magic is added to minimize code duplication. As obviously these two defines need different names, the name of the old device is #defined to the new one when building for only one of imx21 or imx27. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/mx2/devices: use SoC-prefixed names where possibleUwe Kleine-König2010-02-08
| | | | | | | There is only NFC_BASE_ADDR left which is defined differently for mx21 and mx27. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/mx2: use cpp magic to create imx-ssi devicesUwe Kleine-König2010-02-08
| | | | | | | This makes the source shorter and easier to verify. While at it switch to use the SoC-prefixed constants. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/mx2: use cpp magic to create imx-mmc devicesUwe Kleine-König2010-02-08
| | | | | | | This makes the source shorter and easier to verify. While at it switch to use the SoC-prefixed constants. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/mx2: use cpp magic to create imx-i2c devicesUwe Kleine-König2010-02-08
| | | | | | | This makes the source shorter and easier to verify. While at it switch to use the SoC-prefixed constants. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/mx2: use cpp magic to create imx_gpt devicesUwe Kleine-König2010-02-08
| | | | | | | This makes the source shorter and easier to verify. While at it switch to use the SoC-prefixed constants. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* arm/mx2: use cpp magic to create spi_imx devicesUwe Kleine-König2010-02-08
| | | | | | | This makes the source shorter and easier to verify. While at it switch to use the SoC-prefixed constants. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>

* imx: define per SOC ..._PHYS_OFFSET and use these in favour of PHYS_OFFSETUwe Kleine-König2010-02-02
| | | | | | | This is a further step in allowing to build a kernel image for more than one imx SOC. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* imx2x: convert serial.c to use soc-prefixed constantsUwe Kleine-König2010-02-02
| | | | | | | This makes the file compilable for a kernel that supports both imx21 and imx27. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* mxc91231: redefine MXC91231_IO_ADDRESS using IMX_IO_ADDRESSUwe Kleine-König2010-02-02
| | | | | | | This simplifies the macro and makes is similar to the other ..._IO_ADDRESS macros defined for imx SOCs. Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* mxc91231: use MXC91231_IO_ADDRESS instead of MXC91231_AIPS1_IO_ADDRESSUwe Kleine-König2010-02-02
| | | | | | | | | | | | | | Apart from MXC91231_IO_ADDRESS itself this was the only usage of MXC91231_AIPS1_IO_ADDRESS. Now MXC91231_IO_ADDRESS can be recoded with IMX_IO_ADDRESS and all helper macros can go away.

* mx25: deprecate UART1_BASE_ADDR and UART2_BASE_ADDRUwe Kleine-König2010-01-30
| | | | Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de>
* mx1: prefix SOC specific defines with MX1_ and deprecate old namesUwe Kleine-König2010-01-30
| | | | | | | | | | | | | | | | | | | | The old names are defined only if the cpp symbol IMX_NEEDS_DEPRECATED_SYMBOLS exists, which is defined (for now) for all files below arch/arm/mach-mx1. This was done earlier for mx2 and mx3, too. USBD_INT0 is for now defined unconditionally to prevent breaking drivers/usb/gadget/imx_udc. While at it use IMX_IO_ADDRESS to define MX1_IO_ADDRESS which adds a cast to the IO_ADDRESS macro fixing many warnings like arch/arm/mach-mx1/generic.c:51: warning: passing argument 1 of 'mxc_init_irq' makes pointer from integer without a cast .

| * mx25: fix time accountingBaruch Siach2010-01-26
| | | | | | | | | | | | | | | | | | The gpt_clk rate function doesn't consider the PER divider. This causes a significant drift in time accounting. Fix this by introducing the correct rate calculation function. Signed-off-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * mx25: properly initialize clocksBaruch Siach2010-01-26
| | | | | | | | | | | | | | | | | | | | This patch disables all unnecessary clock in mx25_clocks_init() to make a clean start, the same as is being done for the rest of the i.MX chips. This patch was tested on i.MX25 PDK. Signed-off-by: Baruch Siach <baruch@tkos.co.il> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
| * mx25: remove unused mx25_clocks_init() argumentBaruch Siach2010-01-26
