From 0dd969d83badb6793519ee99dd8ab8579d5f59df Mon Sep 17 00:00:00 2001 From: Steve Marple Date: Sat, 25 Jun 2022 23:45:18 +0100 Subject: drivers/bcm2835gpio: Migrate to adapter gpio commands Use the new "adapter gpio" commands to configure the GPIOs used by the bcm2835gpio driver. The driver supports only 1 chip (gpiochip0). The reset function now honours the srst_open_drain and trst_open_drain options.
