From 48609d0789f811014b33e6eefc2c27c99be7fea7 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sat, 7 Aug 2021 07:24:12 -0600 Subject: dm: gpio: Add of-platdata support Add support for accessing GPIOs using of-plata. This uses the same mechanism as for clocks, but allows use of the xlate() method so that the driver can interpret the parameters. Update the condition for GPIO_HOG so that it is not built into SPL, since it needs SPL_OF_REAL which is not enabled in sandbox_spl.
