This series cleans up I2C clock selection for Freescale/NXP MPC SoCs during
the controller initialization for cases when clock settings are not to be
preserved from the bootloader.
Patch 1/4 fixes division by zero which happens during controller
initialization when (1) clock frequency is not speci
According to the reference manuals for the corresponding SoCs, SEC
frequency ratio configuration is indicated by bit 26 of the POR Device
Status Register 2. Consequently, SEC_CFG bit should be tested by mask 0x20,
not 0x80. Testing the wrong bit leads to selection of wrong I2C clock

Commit 8ce795cb0c6b ("i2c: mpc: assign the correct prescaler from SVR")

Remove the facility for setting the prescaler value at compile time
entirely. It was only used for two SoCs, duplicating the actual value
for one of them and setting sometimes bogus value for another. Make all

Currently only get_user_pages_fast() can safely handle the writable gup
case due to its use of pud_access_permitted() to check whether the pud
entry is writable. In the gup slow path pud_write() is used instead of
pud_access_permitted() and to date it has been unimplemented, just calls
BUG_ON().
