Update Armada 38x UART device tree binding

2018-10-10T10:34:17Z

Recent changes in Linux updated Marvell Armada 38x UART compatible string. As a result the FreeBSD driver (uart_dev_snps) does not probe. This commit fixes the situation, however not applying any functional modification to the driver methods. Approved by: re (kib) Obtained from: Semihalf

add snps IP uart support / genaralize UART

2018-08-19T21:10:21Z

This is an amalgam of a patch by Doug Ambrisko to generalize uart_acpi_find_device, imp moving the ACPI table to uart_dev_ns8250.c and advice by jhb to work around a bug in the EPYC 3151 BIOS (the BIOS incorrectly marks the serial ports as disabled) Reviewed by: imp MFC after: 8 weeks Differential Revision: https://reviews.freebsd.org/D16432

uart_snps: Add early printf support

2018-05-01T13:57:08Z

Move the allwinner early printf support to the snps driver as it should work with all implementation. While here add instruction for enabling it on 64bits SoCs.

Do pass removing some write-only variables from the kernel.

This reduces noise when kernel is compiled by newer GCC versions, such as one used by external toolchain ports.

Allow setting access-width for UART registers.

2017-02-27T20:08:42Z

This is required for FDT's standard "reg-io-width" property (similar to "reg-shift" property) found in many DTS files. This fixes operation on Altera Arria 10 SOC Development Kit, where standard ns8250 uart allows 4-byte access only.

EXTRES: Add OF node as argument to all _get_by_ofw_() functions.

2016-07-10T18:28:15Z

In some cases, the driver must handle given properties located in specific OF subnode. Instead of creating duplicate set of function, add 'node' as argument to existing functions, defaulting it to device OF node. MFC after: 3 weeks
