Subject: [PATCH v5 08/31] clk: at91: clk-master: use clk_parent_data
Date: Fri, 16 Jan 2026 13:07:01 -0700 [thread overview]
Message-ID: <548c567b5144e3556aee5e39a9c11ed13167a14a.1768512290.git.ryan.wanner@microchip.com> (raw)
In-Reply-To: <cover.1768512290.git.ryan.wanner@microchip.com>
From: Claudiu Beznea <claudiu.beznea@tuxon.dev>
Use struct clk_parent_data instead of struct parent_hw as this leads
to less usage of __clk_get_hw() in SoC specific clock drivers and simpler
conversion of existing SoC specific clock drivers from parent_names to
modern clk_parent_data structures.
__clk_get_hw will be removed in subsequent patches.
Signed-off-by: Claudiu Beznea <claudiu.beznea@tuxon.dev>
[ryan.wanner@microchip.com: Add clk-master changes to SAM9X75 and
SAMA7D65 SoCs. As well as add md_slck commit message.]
