Subject: [PATCH v2 0/2] Introduce MediaTek CCI devfreq driver
Date: Fri, 8 Apr 2022 13:21:48 +0800 [thread overview]
Message-ID: <20220408052150.22536-1-johnson.wang@mediatek.com> (raw)
The Cache Coherent Interconnect (CCI) is the management of cache
coherency by hardware. CCI DEVFREQ is DVFS driver for power saving by
scaling clock frequency and supply voltage of CCI. CCI uses the same
input clock source and power rail as LITTLE CPUs on Mediatek SoCs.
This series depends on:
Chanwoo's repo: kernel/git/chanwoo/linux.git
branch: devfreq-testing
[1]: PM / devfreq: Export devfreq_get_freq_range symbol within devfreq
[2]: PM / devfreq: Add cpu based scaling support to passive governor
[3]: PM / devfreq: passive: Reduce duplicate code when passive_devfreq case
[4]: PM / devfreq: passive: Update frequency when start governor
Changes in v2:
- Take MT8183 as example in binding document.
- Use dev_err() instead of pr_err().
- Use 'goto' statement to handle error case.
- Clean up driver code.
