* MLK-10981 mxc: ocotp fix hole in shadow registersPeng Fan2015-05-29-5/+74
| | | | | | | | | | | | | | | | | | | | 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, we 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, we use register offset, so need to account for holes to get the correct address. When writing, we use bank/word index, there is no need to account for holes, always use bank/word index from fuse map.

* MLK-10178-5 ocotp:mxc add i.MX7D supportPeng Fan2015-04-29-2/+74
| | | | | | | | | | | | Ocotp of i.MX7D has different operation rule. This patch is to add support for i.MX7D ocotp. Note: DIV_ROUND is changed to DIV_ROUND_CLOSEST Signed-off-by: Peng Fan <Peng.Fan@freescale.com> Signed-off-by: Ye.Li <B37916@freescale.com> (cherry picked from commit d0c3564b6a0f430254edcd8db1f33588bbeccb08)
* mxc_ocotp: Do not disable the OCOTP clock after every accessFabio Estevam2014-12-01-2/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Leave the OCOTP turned on, so that we subsequent access do not fail.

Then when the MAC address is read (also from ocotp registers) it will cause a hang. Do not disable the ocotp clock to prevent this problem.

* replace DIV_ROUND with DIV_ROUND_CLOSESTMasahiro Yamada2014-11-20-2/+2
| | | | | | | | | | | | | The Linux-compatible macro DIV_ROUND_CLOSEST is a bit more flexible and safer than DIV_ROUND. For example, foo = DIV_ROUND_CLOSEST(x, y++) works expectedly, but foo = DIV_ROUND(x, y++) does not. (y is incremented twice.) Signed-off-by: Masahiro Yamada <yamada.m@jp.panasonic.com>
