Subject: [PATCH v4 09/31] clk: at91: clk-programmable: use clk_parent_data
From: Claudiu Beznea <claudiu.beznea@...on.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.
Subsequent patches will aim to completely remove __clk_get_hw().

[ryan.wanner@...rochip.com: Add the clk-programmable changes to the
SAMA7D65 and SAM9X75 SoCs.]
