Subject: [PATCH 4/8] clk: meson: axg: migrate to the new parent description method
Date: Mon, 22 Jul 2019 11:54:21 +0200	[thread overview]
Message-ID: <20190722095425.14193-5-amergnat@baylibre.com> (raw)
In-Reply-To: <20190722095425.14193-1-amergnat@baylibre.com>

This clock controller use the string comparison method to describe parent
relation between the clocks, which is not optimized.

Migrate to the new way by using .parent_hws where possible (ie. when
all clocks are local to the controller) and use .parent_data otherwise.

Subject: [PATCH 4/8] clk: meson: axg: migrate to the new parent description method
Date: Mon, 22 Jul 2019 11:54:21 +0200	[thread overview]
Message-ID: <20190722095425.14193-5-amergnat@baylibre.com> (raw)
In-Reply-To: <20190722095425.14193-1-amergnat@baylibre.com>

This clock controller use the string comparison method to describe parent
relation between the clocks, which is not optimized.

Migrate to the new way by using .parent_hws where possible (ie. when
all clocks are local to the controller) and use .parent_data otherwise.

Subject: [PATCH 4/8] clk: meson: axg: migrate to the new parent description method
Date: Mon, 22 Jul 2019 11:54:21 +0200	[thread overview]
Message-ID: <20190722095425.14193-5-amergnat@baylibre.com> (raw)
In-Reply-To: <20190722095425.14193-1-amergnat@baylibre.com>

This clock controller use the string comparison method to describe parent
relation between the clocks, which is not optimized.

Migrate to the new way by using .parent_hws where possible (ie. when
all clocks are local to the controller) and use .parent_data otherwise.
