Enable support for USI block. USI (Universal Serial Interface) is an
|
||
|
IP-core found in modern Samsung Exynos SoCs, like Exynos850 and
|
||
|
ExynosAutoV9. USI block can be configured to provide one of the
|
||
|
following serial protocols: UART, SPI or High Speed I2C.
|
||
|
|
||
|
This driver allows one to configure USI for desired protocol, which
|
||
|
is usually done in USI node in Device Tree.

Enable the PM code's memory area checksum over sleep. This option
|

|
will generate CRCs of all blocks of memory, and store them before
|
||
|
going to sleep. The blocks are then checked on resume for any
|
||
|
errors.
|
||
|
|
||
|
Note, this can take several seconds depending on memory size
|
||

and CPU speed.

Set the chunksize in Kilobytes of the CRC for checking memory
|
||
|
corruption over suspend and resume. A smaller value will mean that
|
||
|
the CRC data block will take more memory, but will identify any
|
||
|
faults with better precision.
