54bcca always populates 'ecc_mode' but forgot to remove the
code which overwrote the previously hardcoded 'NAND_ECC_SOFT'
when needed. This is obsolete now.

usbphy initializaion needs to access the power supply and has this
embedded. Refactor to a seperate power.c, since we need other accesses
in the future.

Let's keep the timeout routine in a central place. We will need it more

Since we now can change HCLK and VDDIO, we can now support writing to
OCOTP. Writing is done via a special data register. This is u32, so we
need to fill a temporary buffer when offset or count is not aligned. The
write is also protected by a special device variable.

Because OCOTP write needs to change HCLK and VDDIO, some preparations are
needed before we can finally write to OCOTP. Tested with a custom board and a
TX28.
Wolfram Sang (8):
arm: mxs: make get_hclk result useable for upcoming set_hclk
arm: mxs: add imx_set_hclk
arm: mxs: refactor access
To avoid getting a different divider due to rounding errors when using
set_hclk later, use DIV_ROUND_UP for the returned value.

Compile fixes unknown symbol 'mxs_ocotp_read' for tx28 defconfig. Since
the vendor stores the MAC address in OCOTP, we always want this driver.

Add read support for the OCOTP so we can get MAC addresses. Also fix the
printout once we got it since it doesn't come from an eeprom.
Wolfram Sang (3):
arm: mxs: add ocotp driver
arm: mxs: tx28: get MAC from OCOTP
net: eth: don't say that MAC comes from EEPROM
arch/arm/boards/karo-tx28
Because it can also come in via other means.
