From ea3628ce85ffcbdacb74170cbca6e829b7e1e0cf Mon Sep 17 00:00:00 2001 From: Pierre Gondois Date: Tue, 9 Nov 2021 17:22:48 +0000 Subject: serial: pl011: Add ACPI SBSA UART match id commit ac442a077acf9a6bf1db4320ec0c3f303be092b3 upstream. The document 'ACPI for Arm Components 1.0' defines the following _HID mappings: -'Prime cell UART (PL011)': ARMH0011 -'SBSA UART': ARMHB000 Use the sbsa-uart driver when a device is described with the 'ARMHB000' _HID. Note: PL011 devices currently use the sbsa-uart driver instead of the uart-pl011 driver. Indeed, PL011 devices are not bound to a clock in ACPI. It is not possible to change their baudrate.
