From 4fa183fe79f5f7fc66750ee0bd2376f5c99ed9b0 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Wed, 6 Jan 2021 20:30:35 -0800 Subject: soc/intel/uart: Drop SoC callback `soc_uart_console_to_device` This change renames `struct uart_gpio_pad_config` to `struct uart_controller_config` and adds a new parameter devfn (which expects devfn for the UART controller corresponding to the index in PCI_DEVFN() format). This gets rid of the SoC callback to get `struct device` pointer to the UART controller device.
