Hi,
Chanes since v1: - removed the ASoC patch as Mark has applied it already - Added my signed-off to the hwmod patch - New patch to handle the case when the sidetone hwmod has been removed for legacy boot.
The series addresses a long standing issue with McBSP2/3 regarding to hwmod setup. When booting with DT a warning is printed that mcbsp2/3 is using two hwmod. The root of the issue is the way how the hwmod data was constructed in the first place for OMAP3 McBSP2/3. After re-reading the TRM it is clear that the sidetone should not have it's own hwmod data as it is not a separate IP, it is part of the McBSP module. It can not affect PRCM either since it's SYSCONFIG register's AUTOIDLE bit is only sets the autoidle from the internal McBSP_iclk clock to the sidetone block of the same McBSP.
