Subject: [PATCH v3 05/11] gpio: vf610: drop unnecessary wrappers
Date: Thu, 05 Nov 2026 11:53:03 +0800	[thread overview]
Message-ID: <20261105-gpio-vf610-fixes-v3-5-504e19de5ad5@nxp.com> (raw)
In-Reply-To: <20261105-gpio-vf610-fixes-v3-0-504e19de5ad5@nxp.com>

From: Peng Fan <peng.fan@nxp.com>

Remove trivial wrapper functions vf610_gpio_writel() and
vf610_gpio_readl() that just called the relaxed versions directly.
Replace their usage with direct calls to writel_relaxed() and
readl_relaxed().
