The UC-2100 series consists many boards with different peripheral
devices and wireless modules, hence we fetch common items and
create a common dtsi file to increase reusability. All boards in
UC-2100 series will include this common dtsi file.

Thanks for updating this, applying into omap-for-v4.20/dt.

requires the exact chip name in addition to the generic "tcg,tpm_tis-spi".
