Rename some struct names and function names to
improve code readability.
Harinath Nampally (3):
iio: accel: mma8452: Rename structs holding event configuration
registers to more appropriate names.
iio: accel: mma8452: Rename time step look up struct to generic
name as the value
'mma8452_read_thresh' and 'mma8452_write_thresh' functions
does more than just read/write threshold values.
They also handle IIO_EV_INFO_HIGH_PASS_FILTER_3DB and
IIO_EV_INFO_PERIOD therefore renaming to generic names.

This patch adds following changes to support tap feature:
- defines pulse event related registers
- enables and handles single pulse interrupt for fxls8471
- handles IIO_EV_DIR_EITHER in read/write callbacks
because event direction for pulse is either rising or
falling.
- configures read/write

The latter is used by the control channel (ring 0). In frame mode each

tpm2_pcr_read() copies the digest stored in a PCR to a buffer provided by
the caller. However, it does not return the digest size, included in the
output from the TPM. Retrieving it would be useful when a TPM algorithm
is not known by the crypto subsystem, which the TPM driver currently

PCRs can be extended by providing the TPM algorithm identifier and
the digest. To correctly build the command buffer, the digest size
must be known.
The TPM driver cannot determine the digest size if the provided

Sorry, I guess I was too impatient. I also messed up the spelling in a
