From b544927d75574330b0a8a33c113556b67df56f39 Mon Sep 17 00:00:00 2001 From: Jialu Xu Date: Sat, 7 Mar 2026 11:06:22 +0800 Subject: [PATCH 1/3] nfc: s3fwrn5: convert to gpio descriptors Replace the legacy of_get_named_gpio() / gpio_request_one() / gpio_set_value() API with the descriptor-based devm_gpiod_get() / gpiod_set_value() API from , removing the dependency on . This removes the s3fwrn5_i2c_parse_dt() and s3fwrn82_uart_parse_dt() functions since devm_gpiod_get() handles both DT lookup and resource management. The gpio_en and gpio_fw_wake fields in struct phy_common are changed from int to struct gpio_desc *. Add rename quirks in gpiolib-of.c for the deprecated "s3fwrn5,en-gpios" and "s3fwrn5,fw-gpios" properties to maintain backward compatibility with old device trees.
