After McBSP driver is hwmod adapted, the information about the hw would be
obtained from the hwmod database by the mcbsp driver. Since DMA programming is
handled by the client driver, APIs are provided to pass the DMA channel number
and base address of data register required by the client driver for DMA
programming.

McBSP2/3 in OMAP3 has sidetone feature which requires autoidle
to be disabled before starting the sidetone. Also SYSCONFIG
register has to be set with smart idle or no idle depending on the
dma op mode (threshold or element sync). For doing these operations
dynamically at runtime, omap_device APIs are used to modify SYSCONFIG register.

Hwmod needs database of all IPs in a system. This patch generates the hwmod
database for Display Sub System applicable for OMAP3430 and
OMAP36xx.  DSS is also considered as an IP as DISPC, RFBI and named as dss_core.
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.

This patch defines separate hwmod databases for OMAP3430ES1 and (OMAP3430ES2 and
OMAP36xx) as OMAP3430ES1 does not have IDLEST bit to poll on for dss IP, and also
the firewall regions are different between 3430es1 and later.

Allow OMAP4 ES2.1 and ES2.2 revisions to be recognized in the
omap4_check_revision() function.

Mainly, ES2.1 has fixes that allow LPDDR to be used at 100% OPP (400MHz).
ES2.2 additionally has a couple of power management fixes (to reduce
leakage), an I2C1 SDA line state fix, and a floating point write
corruption fix (cortex erratum).

Even though the current mainline support doesn't need to distinguish
between ES2.X versions, it's still useful to know the correct silicon
rev when issues are reported. Moreover, these id checks can be used by
power management code that selects suitable OPPs considering the
memory speed limitation on ES2.0.
