[PATCH 0/8] TI AM335x TSC/ADC cleanup

[PATCH 0/8] TI AM335x TSC/ADC cleanup

[Andrew F. Davis]

Hello all,

This series is a group of non-functional changes I would
like to get in this cycle to prepare some regmap based
changes I would like to make next cycle. Hopefully the
churn can be seen as more useful in that case.

Thanks,
Andrew

Right.  I usually push back on these type of abstraction when they are
submitted.

[PATCH 4/8] mfd: ti_am335x_tscadc: Unify variable naming when refrencing ti_tscadc_dev

[Andrew F. Davis]

All functions in this driver reference the same ti_tscadc_dev per device
but use several different names for this structure pointer, this can
be confusing when following the code. Use the name 'tscadc' everywhere.

[PATCH 5/8] mfd: ti_am335x_tscadc: Rename regmap_tscadc to regmap

[Andrew F. Davis]

The regmap structuer pointer is named regmap_tscadc, this is not
consistent with other drivers and is redundant, it also contributes
to several checkpatch warnings involving long lines. Rename this.

of using the actual variables to determize the size using
the sizeof() operator.

[PATCH 8/8] Input: ti_am335x_tsc - use variable name for sizeof() operator

[Andrew F. Davis]

Fix the code formatting to use the kernel preferred style
of using the actual variables to determize the size using
the sizeof() operator.
