Any time I see platform data and pdata I think about board-specific
parameters that come either from board initialization code, device tree
or ACPI, rather than chipset specific data. Do you think we could rename
rockchip_tsadc_platform_data to rockchip_tsadc_chip? If you agree
please fold the patch below into your next revision.
More to come...
Thanks.
