This patch series adds support for HDQ-1W interface on AM43XX.
The first patch adds hwmod entries for HDQ-1W on AM43xx.

The existing omap_hdq driver does not support 1-wire operations.
The second patch enables 1-wire support in the omap_hdq driver. Support
to Search ROM addresses and automatically load slave drivers is added
for 1-wire mode.

I have tested this on am437x-gp-evm using DS18B20 as 1-wire slave.
