From e87e86f31c54a4e49159dca7fbd6d9694efcd720 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Thu, 4 Feb 2021 21:22:02 -0700 Subject: [PATCH] gpio: sandbox: Make sandbox_gpio_set_flags() set all flags Allow this function to see all flags, including the internal sandbox ones. This allows the tests to fully control the behaviour of the driver. To make this work, move the setting of GPIOD_EXT_HIGH -to where the flags are updated via driver model, rather than the sandbox 'back door'.
