2009-05-05MXC: remove BUG_ON in interrupt handlerSascha Hauer
On i.MX31 I sometimes get spurious interrupts. There is no need to crash the whole system when this happens. Instead, silently ignore it. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2009-05-05mxc : BUG in imx_dma_requestMartin Fuzzey
On MX2 platforms imx_dma_request() calls request_irq() which may sleep with interrupts disabled. Signed-off-by: Martin Fuzzey <mfuzzey@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2009-05-05mxc : Clean up properly when imx_dma_free() used without imx_dma_disable()Martin Fuzzey
The sequence imx_dma_request() imx_dma_enable() imx_dma_free() left the dma channel in_use mode and did not release the timer. Signed-off-by: Martin Fuzzey <mfuzzey@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

Set the correct clkdev-name for the i2c clock. It also get's rid of the ARCH_NR_GPIOS define on the rationale that isn't an ARCH-wide setting anyway. If a device has two pca953x devices, the reserved number will be wrong. Signed-off-by: Holger Schurig <hs4233@mail.mn-solutions.de>

2009-03-19[ARM] pass reboot command line to arch_reset()Russell King
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.

2009-03-13[ARM] MX35: add clock supportSascha Hauer
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>
2009-03-13[ARM] MXC: add cpu_is_ macrosSascha Hauer
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. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2009-03-13[ARM] MX35: Add register definitions for the i.MX35Sascha Hauer
This patch moves the stuff common to i.MX31 and i.MX35 to mx3x.h and the specifics to mx31.h/mx35.h. We can build a kernel which runs on i.MX31 and i.MX35, so always include mx31.h and mx35.h Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
2009-03-13mx31moboard: initial support for various baseboardsValentin Longchamp
This enables our mx31moboard to be used on the different baseboards that we are developping according to the application needs.

2009-03-13mx31: rework of iomux supportValentin Longchamp
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>
2009-03-13mx31ads: Fix build for missing mx31.hMark Brown

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

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.
