MLK-11371-1 char: add fsl_otp device driver
This is porting of fsl_otp driver from imx_3.14.y to imx_4.1.y.
This patch mainly from the following:
commit:292eff6d2c9064ecf15ed457140c1d743c2ead67
"ENGR00269945: char: add fsl_otp deivce driver"
This is a porting of fsl_otp driver from 3.0.35 kernel to 3.10. It
cleans up the driver a little bit and adds device tree probe support.
shawn.guo: cherry-pick commit 850237dccde7 from imx_3.10.y.
commit:057a50039fac872fd19fe6c129a94face4231ae8
"MLK-10979-4 imx: ocotp add i.MX7D support and fix hole"
1. Add i.MX7D support
2. Fix hole addressing.
There is a hole in shadow registers address map of size 0x100
between bank 5 and bank 6 on iMX6QP, iMX6DQ, iMX6SDL, iMX6SX and
iMX6UL. Bank 5 ends at 0x6F0 and Bank 6 starts at 0x800. When reading
the fuses, should account for this hole in address space.
Similar hole exists between bank 14 and bank 15 of size 0x80 on
iMX6QP, iMX6DQ, iMX6SDL and iMX6SX.
Note: iMX6SL has only 0-7 banks and there is no hole.
Note: iMX6UL doesn't have this one.
When reading, the hole need to be considered to calculated the physical
address offset.
When writing, since only word index for i.MX6 and bank
index for i.MX7, there is no need to take the hole into consideration,
still use the bank/word index from fuse map.
3. Add i.MX6SL i.MX6UL fuse map table.
4. Tested read/write on mx6ul-14x14-ddr3-arm2 and mx7d-12x12-lpddr3-arm2 board.
Tested read on mx6sxsabresd board.
