This patch reads charge delay from tsc DT node and writes to
REG_CHARGEDELAY register. If the charge delay is not specified in DT
then default value of 0x400(CHARGEDLY_OPENDLY) is used.

v5:
- enable TSC steps only on EOS interrup
v4:
- check for PEN_IRQ bit in ADCFSM to avoid false-pen when ADC
and TSC are used together.
- Set charge delay to 0x400 as default. Most devices
is
more sensible than delta filering. Median filtering is applied only if number
of readouts is greater than 3 else just average of co-ordinate readouts is
reported.

of the
config steps except for the charge step. Previously charge step was 1 ADC
clock cycle and hence it was ignored.
TSC steps are always disabled at the end of each conversion cycle, hence
there is no need to explicitly disable TSC steps by writing 0 to REG_SE.

The charge delay value is by default 0x400. But it can be set to lower
values on some boards, as long as false pen-ups are avoided. Lowering the
value increases the sampling rate (though
data to reflect the right clk source.
Tested on beaglebone and am437x-gp-evm.

and averaging helps to achieve higher sampling rates, while increasing
this parameters provides greater accuracy. Hence, this patch provides DT
properties to set the initial values for delays and number of averages
per sample. User space control via sysfs can be added later.
