Subject: [PATCH v4 00/14] Add regulator devfreq support to Panfrost
Date: Fri, 10 Jul 2020 11:25:34 +0200 [thread overview]
Message-ID: <20200710092548.316054-1-peron.clem@gmail.com> (raw)
Hi,
This serie cleans and adds regulator support to Panfrost devfreq.
This is mostly based on comment for the freshly introduced lima
devfreq.
We need to add regulator support because on Allwinner the GPU OPP
table defines both frequencies and voltages.
First patches [01-07] should not change the actual behavior
and introduce a proper panfrost_devfreq struct.
Regards,
Clément
Changes since v3:
- Collect Steven Price reviewed-by tags
- Rebase on next/master (next-20200709)
Changes since v2:
- Collect Alyssa Rosenzweig reviewed-by tags
- Fix opp_set_regulator before adding opp_table (introduce in v2)
- Call err_fini in case opp_add_table failed
Changes since v1:
- Collect Steven Price reviewed-by tags
- Fix spinlock comment
- Drop OPP clock-name patch
- Drop device_property_test patch
- Add rename error labels patch
