[PATCH 00/12] ipa: rkisp1: Miscellaneous AGC fixes

[Laurent Pinchart]

Hello,

This patch series contains a set of assorted AGC fixes and enhancements
for the rkisp1, as well as the agc_mean_luminance helper.

Patch 01/12 fixes a regression in the recently merged histogram weights
support. It should be fast-tracked, as the master branch is currently
broken for users who don't have AE metering modes in their tuning file.

There's not much else to be said about the series here, please see
individual patches for details.
