Subject: [PATCH 2/3] ARM: OMAP3: hwmod data: Merge and remove the McBSP sidetone related data
McBSP2 and 3 have integrated sidetone block. The sidetone alone can not
operate, can not be enabled separately from the McBSP it is attached to.
The sidetone is enabled via McBSP register(s) and it is using the McBSP
module's iclk as clock. While the sidetone block of McBSP does have it's
SYSCONFIG registers to enable/disable AUTOIDLE (of McBSP_ICLK) this alone
does not mean that we should have dedicated hwmod for McBSP internal
blocks. Note: The AUTOIDLE bit is set after reset and hwmod is not changing
it in runtime.
The sidetone can not be enabled separately from McBSP, it can only enabled
when McBSP is in use.
Furthermore the sidetone data is specifying the exact same prcm registers
and bits as the McBSP hwmod it is attached to.
As one of the main function of the sidetone hwmod data is to convey the
address and irq number to the main mcbsp hwmod, move them directly to the
corresponding McBSP's hwmod data.
