From: Senthilvadivu Guruswamy <svadivu@xxxxxx>
Hwmod needs database of all IPs in a system. This patch generates the hwmod
database for Display Sub System applicable for OMAP3430-ES2 onwards and
OMAP36xx. DSS is also considered as an IP as DISPC, RFBI and named as dss_dss.
For all the IP modules in DSS, same clock is needed for enabling. Hwmod sees
DSS IPs as independent IPs, so same clock has to be repeated for .main_clk in
each IP.
OMAP3430ES1 do not have IDLEST bit to poll on for dss IP. So this hwmod is
not applicable for 3430ES1.
