From: Claudiu Beznea Date: Thu, 15 Jun 2023 09:32:20 +0000 (+0300) Subject: clk: at91: clk-peripheral: add support for parent_hw X-Git-Tag: v6.6.7~2431^2~2^3^2~7 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c2f2ca0be8a62ce61a6878cd3dddd8fc6d622999;p=platform%2Fkernel%2Flinux-starfive.git clk: at91: clk-peripheral: add support for parent_hw Add support for parent_hw in peripheral clock drivers. With this parent-child relation is described with pointers rather than strings making registration a bit faster. All the SoC based drivers that rely on clk-peripheral were adapted to the new API change. The switch itself for SoCs will be done in subsequent patches.
