License cleanup: add SPDX license identifier to uapi header files with a license Many user space API headers have licensing information, which is either incomplete, badly formatted or just a shorthand for referring to the license under which the file is supposed to be. This makes it hard for compliance tools to determine the correct license. Update these files with an SPDX license identifier. The identifier was chosen based on the license information in the file. GPL/LGPL licensed headers get the matching GPL/LGPL SPDX license identifier with the added 'WITH Linux-syscall-note' exception, which is the officially assigned exception identifier for the kernel syscall exception: NOTE! This copyright does *not* cover user programs that use kernel services by normal system calls - this is merely considered normal use of the kernel, and does *not* fall under the heading of "derived work". This exception makes it possible to include GPL headers into non GPL code, without confusing license compliance tools. Headers which have either explicit dual licensing or are just licensed under a non GPL license are updated with the corresponding SPDX identifier and the GPLv2 with syscall exception identifier. The format is: ((GPL-2.0 WITH Linux-syscall-note) OR SPDX-ID-OF-OTHER-LICENSE) SPDX license identifiers are a legally binding shorthand, which can be used instead of the full boiler plate text. The update does not remove existing license information as this has to be done on a case by case basis and the copyright holders might have to be consulted. This will happen in a separate step. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. See the previous patch in this series for the methodology of how this patch was researched.

serial: pch_uart: Make port type explicit It used to be a gap in port definitions after PORT_MAX_8250. Since the new drivers are coming the gap become shorter and shorter until the commit a2d6a987bfe4 ("serial: 8250: Add new port type for TI DA8xx/66AK2x") completely removed it. So, while type here is just a formality, make things a little bit more explicit for this driver and move port types to UAPI header. Note, it uses two types for now.

serial: 8250: of: Add new port type for MediaTek BTIF controller on MT7622/23 SoC MediaTek BTIF controller is the serial interface similar to UART but it works only as the digital device which is mainly used to communicate with the connectivity module called CONNSYS inside the SoC which could be mostly found on those MediaTek SoCs with Bluetooth feature such as MT7622 and MT7623 SoCs. And the controller is made as being compatible with the 8250 register layout with extra registers such as DMA enablement so it tends to be integrated with reusing 8250 OF driver. However, DMA mode is not being supported yet in the current driver.

tty: serial: add driver for the SiFive UART Add a serial driver for the SiFive UART, found on SiFive FU540 devices (among others). The underlying serial IP block is relatively basic, and currently does not support serial break detection. Further information on the IP block can be found in the documentation and Chisel sources: https://static.dev.sifive.com/FU540-C000-v1.0.pdf https://github.com/sifive/sifive-blocks/tree/master/src/main/scala/devices/uart This driver was written in collaboration with Wesley Terpstra <wesley@sifive.com>. Tested on a SiFive HiFive Unleashed A00 board, using BBL and the open- source FSBL (using a DT file based on what's targeted for mainline). This revision incorporates changes based on comments by Julia Lawall <julia.lawall@lip6.fr>, Emil Renner Berthing <kernel@esmil.dk>, and Andreas Schwab <schwab@suse.de>. Thanks also to Andreas for testing the driver with his userspace and reporting a bug with the set_termios implementation.

tty: serial: Add linflexuart driver for S32V234 Introduce support for LINFlex driver, based on: - the version of Freescale LPUART driver after commit b3e3bf2ef2c7 ("Merge 4.0-rc7 into tty-next"); - commit abf1e0a98083 ("tty: serial: fsl_lpuart: lock port on console write"). In this basic version, the driver can be tested using initramfs and relies on the clocks and pin muxing set up by U-Boot. Remarks concerning the earlycon support: - LinFlexD does not allow character transmissions in the INIT mode (see section 47.4.2.1 in the reference manual[1]). Therefore, a mutual exclusion between the first linflex_setup_watermark/linflex_set_termios executions and linflex_earlycon_putchar was employed and the characters normally sent to earlycon during initialization are kept in a buffer and sent afterwards. - Empirically, character transmission is also forbidden within the last 1-2 ms before entering the INIT mode, so we use an explicit timeout (PREINIT_DELAY) between linflex_earlycon_putchar and the first call to linflex_setup_watermark. - U-Boot currently uses the UART FIFO mode, while this driver makes the transition to the buffer mode. Therefore, the earlycon putchar function matches the U-Boot behavior before initializations and the Linux behavior after.
