Subject: [PATCH v7 0/3] PM / AVS: SVS: Introduce SVS engine
Date: Mon, 16 Mar 2020 15:23:14 +0800 [thread overview]
Message-ID: <20200316072316.7156-1-roger.lu@mediatek.com> (raw)
1. SVS driver use OPP adjust event in [1] to update OPP table voltage part.
2. SVS dts node refers to CPU opp table [2] and GPU opp table [3].
3. SVS and thermal dts use the same thermal efuse [4].
4. SVS dts needs PMIC regulator [5].
[1] https://patchwork.kernel.org/patch/11193513/
[2] https://patchwork.kernel.org/patch/11304935/
[3] https://patchwork.kernel.org/patch/11423009/
[4] https://patchwork.kernel.org/patch/11316495/
[5] https://patchwork.kernel.org/patch/11284617/
pending discussion on v7:
- SVS sub-node architecture pending discussion in below patch.
https://lore.kernel.org/patchwork/patch/1175994/
changes since v6:
- svs_isr_handler() function is merged into svs_isr().
- In svs_isr(), we find which bank fires interrupt first and check this bank
is suspended or not secondly.
- Use memdup_user_nul() instead of copy_from_user().
- Use U32_MAX instead of "(u32)-1.
- SVS needs to do resume after thermal resume in system suspend flow.
Therefore, change SVS pm_ops to prepare/complete.
- Add high temperature voltages compensation codes.
- Add irqflags in "struct svs_platform" for supporting different SVS HW setting.
- Set signed-off voltages to system when system suspend.
- Add SVS HW reset flag for future SVS HW support.
- Coding style refinement.
