clk: ti: Fix missing omap5 mcbsp functional clock and aliases
[ Upstream commit 0b9a4a67c60d3e15b39a69d480a50ce7eeff9bc1 ]
We are using a wrong mcbsp functional clock. The interconnect target module
driver provided clock for mcbsp is not same as the mcbsp functional clock
known as the gfclk main_clk. The mcbsp functional clocks for mcbsp should
have been added before we dropped the legacy platform data.
Additionally we are also missing the clock aliases for the clocks used by
the audio driver if reparenting is needed. This causes audio driver errors
like "CLKS: could not clk_get() prcm_fck" for mcbsp as reported by Andreas.
The mcbsp clock aliases too should have been added before we dropped the
legacy platform data.
Let's add the clocks and aliases with a single patch to fix the issue
similar to omap4. On omap5, there is no mcbsp4 instance on the l4_per
interconnect.
