Subject: [PATCH V2 01/12] clk: mediatek: reset: Fix written reset bit offset
Date: Wed, 20 Apr 2022 21:05:16 +0800 [thread overview]
Message-ID: <20220420130527.23200-2-rex-bc.chen@mediatek.com> (raw)
In-Reply-To: <20220420130527.23200-1-rex-bc.chen@mediatek.com>
Original assert/deassert bit is BIT(0), but it's more resonable to modify
them to BIT(id % 32) which is based on id.
This patch will not influence any previous driver because the reset is
only used for thermal. The id (MT8183_INFRACFG_AO_THERM_SW_RST) is 0.
Fixes: 64ebb57a3df6 ("clk: reset: Modify reset-controller driver")
