[PATCH] clk: qcom: rpmh: add support for SM6350 rpmh IPA clock

[Alex Elder]

From: Luca Weiss <luca.weiss@fairphone.com>

The IPA core clock is required for SM6350.  Define it.

This can use sdm845_ipa.hw instead of defining new clocks.

So you're saying that the above line is unnecessary...

...and that this line (above) can instead look like this:

	[RPMH_IPA_CLK]		= &sdm845_ipa.hw,

Correct?

Your statement seems to also be true for the [RPMH_IPA_CLK]
entry in sdx55_rpmh_clocks[].  (For the record, the commit
that added that one was authored by me, and I didn't realize
what you have stated here.)

Please confirm, and I'll update.

I'll also send another patch to remove the definition of
sdx55_ipa if Mani is willing to test it for me...

Thank you Dmitry.
