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.

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.

SW_WKUP. This is based on the input from the hardware team.
The rest of the patches add hwmod and dt entries and enable PWMSS on
DRA7 based SoCs.
Vignesh R (5):
ARM: OMAP2+: DRA7: clockdomain: change l4per2_7xx_clkdm to SW_WKUP
ARM: OMAP2+: DRA7: Add hwmod entries for PWMSS

Legacy IPs like PWMSS, present under l4per2_7xx_clkdm, cannot support
smart-idle when its clock domain is in HW_AUTO on DRA7 SoCs. Hence,
program clock domain to SW_WKUP.
