[PATCH v3 0/9] RPMPD for QCS404 and MSM8998

[Sibi Sankar]

Re-worked the macros of the rpmpd driver. Add power domains support
for QCS404 and MSM8998.

V3:
* always send level updates to vfc and vfl in set_performance state
* fixup commit messages [Rajendra]
* fixup s-o-b ordering

V2:
* Add rpmpd support for msm8998
* fixup corner/vfc with vlfl/vfl

[PATCH v3 1/9] soc: qcom: rpmpd: fixup rpmpd set performance state

[Sibi Sankar]

Remoteproc q6v5-mss does set_performace_state with INT_MAX on
rpmpd. This is currently ignored since it is greater than the
max supported state. Fixup rpmpd state to max if the required
state is greater than all the supported states.

Fixes: 075d3db8d10d ("Add support for the .set_performace_state() and
.opp_to_performance_state()")

AFAIU, the Fixes tag should be on a single line, and quote the commit subject.
(And no blank line between Fixes and Signed-off-by tags.)

Fixes: 075d3db8d10d ("soc: qcom: rpmpd: Add support for get/set performance state")

comments were included to add value
though, however I guess the comments
were definitely not clear enough.
The magic values for the resources
are calculated as follows:

ascii to hex in reverse order
eg: smpa -> 0x61706d73

0x61 0x70 0x6d 0x73
   a    p    m    s

Ah... I see now.

I agree that explaining *why* e.g. RPMPD_SMPA is defined as 0x61706d73
is worthwhile indeed.

What I meant is that adding /* smpa */ to a macro named RPMPD_SMPA does
not really bring any new information ;-)

How about prefixing the whole block with a small blurb, for example

/* The value of RPMPD_X is X encoded as a little-endian, lower-case, ASCII string */

Regards.

yeah I got that

typo in opp5 - opp10 rpmhpd/rpmpd
will fix it in the next re-spin

Hello Sibi,

Please note that you sent this series to linux-arm-msm-owner@vger.kernel.org
instead of linux-arm-msm@vger.kernel.org (the admin instead of the list).

This seems to be the case for other patches as well.

Regards.
