* [ARM] MX35: Add register definitions for the i.MX35Sascha Hauer2009-03-134-323/+329
| | | | | | | | 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>

* mx31moboard: initial support for various baseboardsValentin Longchamp2009-03-135-18/+154
| | | | | | | | | | | | This enables our mx31moboard to be used on the different baseboards that we are developping according to the application needs. There are not many differences between the boards for now, but when other peripherals are available for mx31 the differences are going to grow. v2: takes Sascha's comments into account Signed-off-by: Valentin Longchamp <valentin.longchamp@epfl.ch> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* mx31ads: Initial support for Wolfson Microelectronics 1133-EV1 moduleMark Brown2009-03-132-0/+303
| | | | | | | | | | | | | | | | The i.MX31ADS supports pluggable PMU modules, including the WM835x based Wolfson Microelectronics 1133-EV1. These boards provide power, audio, RTC and watchdiog services to the system. This patch adds initial support for those boards in I2C mode. Currently support is limited by the available support for the features of the i.MX31 in the mainline kernel. Some further work will be needed once other PMU modules are supported and once there is SPI support. Many of the regulator constraints will be sharable with other PMU boards.

* mx31: rework of iomux supportValentin Longchamp2009-03-132-11/+122
| | | | | | | | | | | | | | | | | | | | | | | 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>

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We've discovered that our AT91SAM9260 board consumed too much power when returning from a slowclock low-power mode. RAM self-refresh is enabled in a bootloader in our case, this is how we saw a difference. Estimated ca. 30mA more on 4V battery than the same state before powersaving. After a small research we found that there seems to be a bogus sdram_selfrefresh_disable() call at the end of at91_pm_enter() call, which overwrites the LPR register with uninitialized value. Please find the suggested patch attached. This patch fixes correct restoring of LPR register of the Atmel AT91 SDRAM controller when returning from a power saving mode.
