2014-07-23mx6: Remove duplication of iomuxc structureFabio Estevam
There is no need to keep iomuxc_base_regs structure as it serves the exact same purpose of the iomuxc structure, which is to provide access to the GPR registers. The additional fields of iomuxc_base_regs are not used. Other advantage of 'iomuxc' is that it has a shorter name and the variable declarations can fit into a single line. So remove iomuxc_base_regs structure and use iomuxc instead. Signed-off-by: Fabio Estevam <fabio.estevam@freescale.com> Acked-by: Stefano Babic <sbabic@denx.de>

2014-07-10i.MX6DL/S: add drive-strength back to pads DISP0_DAT2/DAT10Eric Nelson
The pad settings for DISP0_DATA02 and DISP0_DAT10 were not set in the same way as DISP0_DAT00-23, causing much flicker in parallel RGB displays on Dual-Lite and Solo processors. These settings now match the i.MX6 Dual and Quad core versions. Note that this fixes a regression in commit b47abc3 and that this is the second time we've had a regression on these two pads (See commit e654ddf).

2014-06-17mx6: Fix definition of IOMUXC_GPR12_DEVICE_TYPE_RCFabio Estevam
mx6 reference manual incorrectly states that the DEVICE_TYPE field of IOMUXC_GPR12 register should be configured as '0010' for setting the PCI controller in RC mode. The correct value should be '0100' instead. This also aligns with the same value used in the mx6 pci kernel driver.

2014-06-06mx6: add structs for mmdc and ddr iomux registersTim Harvey
Add memory-mapped structures for MMDC iomux and configuration. Note that whi the MMDC configuration registers are common between the IMX6DQ (IMX6DUAL/IMX6QUAD) and IMX6SDL (IMX6SOLO/IMX6DUALLITE) types the iomux registers differ. This requires two sets of structures. Add structures to describe DDR3 device information, system information (memory layout, etc), and MMDC calibration registers that can be used to configure the MMDC dynamically. We define these structures for SPL builds instead of including mx6q-ddr.h an mx6dl-ddr.h which use the same namespace and are only useful for imximage cf files.

Resolution consists in adjusting the list of object files in the main branch version. This also applies to two files which are not listed as conflicting but had to be modified: board/compulab/common/Makefile board/udoo/Makefile include/configs/omap4_common.h conflicts are due to the OMAP4 conversion to ti_armv7_common.h on the ARM side, and CONFIG_SYS_HZ removal on the main side. Resolution is to convert as this icludes removal of CONFIG_SYS_HZ. include/configs/pdnb3.h is due to a removal on ARM side. Trivial resolution is to remove the file. Note: 'git show' will also list two files just because they are new: include/configs/am335x_igep0033.h include/configs/omap3_igep00x0.h
