2015-09-02imx: mx31 use new formula for get_cpu_revPeng Fan
Use new formula for get_cpu_rev, since we need to use this formula to do runtime check for all i.MXes. Signed-off-by: Peng Fan <Peng.Fan@freescale.com> Cc: Stefano Babic <sbabic@denx.de> Reviewed-by: Stefano Babic <sbabic@denx.de>

2012-10-15imx: Use MXC_I2C_CLK in imx i2c driverMatthias Weisser
i2c didn't work on imx25 due to missing MXC_IPG_PERCLK. Now using MXC_I2C_CLK on all imx systems using i2c. Signed-off-by: Matthias Weisser <weisserm@arcor.de> Acked-by: Stefano Babic <sbabic@denx.de>

Add missing reset reason 7 to get_reset_cause(). Signed-off-by: Helmut Raiger <helmut.raiger@hale.at>
2012-02-12mmc: access mxcmmc from mx31 boardsHelmut Raiger
This patch modifies mxcmmc.c to be used not only by i.MX27 but also by i.MX31 boards. Both use the same SD controller, but have different clock set-ups. The i.MX27 imx_get_XXXclock functions are made static to generic.c and a public mxc_get_clock() function is provided. Pins, base address and prototypes for an i.MX31 specific board_init_mmc() are provided. Some of the i.MX27 clock getters are unused and marked as such to avoid warnings (./MAKEALL -s mx27), but the code was left in for future use.

2011-11-03mx31: Introduce mx31_set_gpr functionFabio Estevam
Introduce mx31_set_gpr function for setting the GPR (General Purpose Register) on MX31. This function can be useful for setting a group of pins into tied to some specific peripherals. Reuse this function from the linux kernel. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com>
2011-10-27mx31: provide readable WEIM CS accessorHelmut Raiger
setup_weimcs() and some macros are added to support the setup for i.MX31 WEIM chip selects. As a compromise between verbosity and readability an ASCII-art'ish bit comment is used instead of bitfields. All i.MX31 boards have been patched to use this approach using a helper program to verify the changes. Signed-off-by: Helmut Raiger <helmut.raiger@hale.at> Acked-by: Stefano Babic <sbabic@denx.de>

2011-05-23MX31: Make get_reset_cause() static and drop unreachable codeStefano Babic

2011-04-27IMX: MX31: Cleanup include files and drop nasty #ifdef in driversStefano Babic
As exception among the i.MX processors, the i.MX31 has headers without general names (mx31-regs.h, mx31.h instead of imx-regs.h and clock.h). This requires several nasty #ifdef in the drivers to include the correct header. The patch cleans up the driver and renames the header files as for the other i.MX processors.
