From: Sumit Garg Date: Thu, 4 Aug 2022 14:27:11 +0000 (+0530) Subject: reset: Convert ipq4019 driver to a generic Qcom driver X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=42588276b3375f20cf372ff59c7d3712f55cf48f;p=u-boot.git reset: Convert ipq4019 driver to a generic Qcom driver Since the base functionality remains the same for a reset driver on Qcom SoCs, so leverage that to convert ipq4019 specific reset driver to a generic Qcom reset driver. With that one just need to provide SoC specific reset table.
