* mx31: remove gpio_request calls from iomux codeValentin Longchamp2009-05-07
| | | | | | | | | | | | Since iomux code is not directly related to gpio on mx31, the calls to gpio_request are removed from iomux.c file. These calls have to be done in platform initialization files. The name of the singe pin call for iomux is also changed to mxc_iomux_alloc_pin.

* 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>
* i.MX31: fix mxc_iomux_set_pad()Guennadi Liakhovetski2008-12-16
| | | | | | | | mxc_iomux_set_pad() is buggy on i.MX31 - it calculates the register and the offset therein wrongly. Fix it. Signed-off-by: Guennadi Liakhovetski <lg@denx.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

* [ARM] Move include/asm-arm/arch-* to arch/arm/*/include/machRussell King2008-08-07

* [ARM] Remove asm/hardware.h, use asm/arch/hardware.h insteadRussell King2008-08-07
| | | | | | | | | Remove includes of asm/hardware.h in addition to asm/arch/hardware.h. Then, since asm/hardware.h only exists to include asm/arch/hardware.h, update everything to directly include asm/arch/hardware.h and remove asm/hardware.h.
