2009-05-07mx31: remove gpio_request calls from iomux codeValentin Longchamp
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. Signed-off-by: Valentin Longchamp <valentin.longchamp@epfl.ch> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
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>
2008-12-16i.MX31: fix mxc_iomux_set_pad()Guennadi Liakhovetski
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>

2008-08-07[ARM] Move include/asm-arm/arch-* to arch/arm/*/include/machRussell King
This just leaves include/asm-arm/plat-* to deal with. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
2008-08-07[ARM] Remove asm/hardware.h, use asm/arch/hardware.h insteadRussell King
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. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
