This patch set is based on these three patches: https://patchwork.ozlabs.org/patch/426621/ https://patchwork.ozlabs.org/patch/426623/ https://patchwork.ozlabs.org/patch/426622/
If want to test this patch set, please first apply the up 3 patches.
This patch set is mainly to add ldo bypass support.
Since pmic related function is not readly in previous patch, patch 1/12, patch 2/12, patch 3/12 is first to add pmic related support, such as power_init_board, related iomux/pad settings and configuration in header file. Then ldo bypass function can be implemented.
patch 4/12 is to update mxc_ccm_regs with more registers, since ldo setting will use them.
patch 5/12 is to update fuse_bank0_regs, since ldo setting will check it.
patch 6/12 is to add a macro for setting voltage easily.
patch 7/12 is to add ldo bypass related common function.
patch 8/12, patch 9/12, patch 10/12, patch 11/12 is to implement ldo_mode_set in different boards' file.
patch 12/12 is to invoke ldo_mode_set in arch_preboot_os. Future work will integrate Device tree for i.MX6 U-Boot. Then we can move it to power_init_board.
More detailed info can see each patch's commit log.
