Subject: [PATCH v2 00/11] PM / devfreq: Remove deprecated 'devfreq' and 'devfreq-events' properties
Date: Fri, 20 Dec 2019 09:24:19 +0900 [thread overview]
Message-ID: <20191220002430.11995-1-cw00.choi@samsung.com> (raw)
In-Reply-To: CGME20191220001759epcas1p131a41a619847d80c64470f7c1920121f@epcas1p1.samsung.com
From: Chanwoo Choi <cw00.choi@samsun.com>
The devfreq and devfreq-event subsystem provided the following two properties:
- Provide 'devfreq' property in order to get the parent devfreq device
by devfreq_get_devfreq_by_phandle() if devfreq device use passive governor.
- Provide 'devfreq-events' property in order to get the devfreq-event device
by devfreq_event_get_edev_by_phandle().
But, two properties name is not proper expressing the h/w
and 'devfreq' word is name of linux subsystem instead of any h/w name.
Hand over the rights for deciding the property name for getting
the devfreq/devfreq-event device on devicetree, to each devfreq driver.
So, replace 'devfreq' and 'devfreq-events' property with following property
name according to each devfreq driver:
--------------------------------------------------------------------
Old property | New property | Device driver name |
--------------------------------------------------------------------
devfreq | exynos,parent-bus | exynos-bus.c |
| | |
devfreq-events| exynos,ppmu-device | exynos-bus.c, exynos5422-dmc.c|
| rockchip,dfi-device| rk3399_dmc.c |
--------------------------------------------------------------------
Changes from v1:
- Edit function name by removing '_by_node' postfix.
- Split out dt-binding patch to make it the separte patch.j
- Add Lukasz's tag for exynos5422-dmc
