2017-11-02License cleanup: add SPDX license identifier to uapi header files with a licenseGreg Kroah-Hartman1-0/+1
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.

2017-08-28serial: 8250: of: Add new port type for MediaTek BTIF controller on MT7622/23 SoCSean Wang1-0/+3
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.

2017-08-28serial: Fix port type numbering for TI DA8xxAndy Shevchenko1-1/+3
The UAPI has a global list of unique numbers for different port types. The commit a2d6a987bfe4 ("serial: 8250: Add new port type for TI DA8xx/66AK2x") introduced a new port type and brought the collision with two other port types. Reuse 95 for it instead.

2017-08-28serial: pch_uart: Make port type explicitAndy Shevchenko1-1/+4
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.

2017-01-12serial: 8250: Add new port type for TI DA8xx/66AK2xDavid Lechner1-1/+2
This adds a new UART port type for TI DA8xx/OMAPL13x/AM17xx/AM18xx/66AK2x. These SoCs have standard 8250 registers plus some extra non-standard registers. The UART will not function unless the non-standard Power and Emulation Management Register (PWREMU_MGMT) is configured correctly. This is currently handled in arch/arm/mach-davinci/serial.c for non-device-tree boards. Making this part of the UART driver will allow UART to work on device-tree boards as well and the mach code can eventually be removed.

There are 10 branches merged here, a total of 39 non-merge commits. Contents are a mixed bag for the above reasons: * Two new SoC platforms: ST microelectronics stixxxx and the TI 'Nspire' graphing calculator. These should have been in the 'soc' branch but were a little late * Support for the Exynos 5420 variant in mach-exynos, which is based on the other exynos branches to avoid conflicts. * Various small changes for sh-mobile, ux500 and davinci * Common clk support for MSM" * tag 'late-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (39 commits) ARM: ux500: bail out on alien cpus ARM: davinci: da850: adopt to pinctrl-single change for configuring multiple pins serial: sh-sci: Initialise variables before access in sci_set_termios() ARM: stih41x: Add B2020 board support ARM: stih41x: Add B2000 board support ARM: sti: Add DEBUG_LL console support ARM: sti: Add STiH416 SOC support ARM: sti: Add STiH415 SOC support ARM: msm: Migrate to common clock framework ARM: msm: Make proc_comm clock control into a platform driver ARM: msm: Prepare clk_get() users in mach-msm for clock-pcom driver ARM: msm: Remove clock-7x30.h include file ARM: msm: Remove custom clk_set_{max,min}_rate() API ARM: msm: Remove custom clk_set_flags() API msm: iommu: Use clk_set_rate() instead of clk_set_min_rate() msm: iommu: Convert to clk_prepare/unprepare msm_sdcc: Convert to clk_prepare/unprepare usb: otg: msm: Convert to clk_prepare/unprepare msm_serial: Use devm_clk_get() and properly return errors msm_serial: Convert to clk_prepare/unprepare ...
2013-06-17serial: sh-sci: HSCIF supportUlrich Hecht1-0/+3

2013-01-17serial: rp2: New driver for Comtrol RocketPort 2 cardsKevin Cernekee1-0/+3
This driver supports the RocketPort EXPRESS and RocketPort INFINITY families of PCI/PCIe multiport serial adapters. These adapters use a "RocketPort 2" ASIC that is not compatible with the original RocketPort driver (CONFIG_ROCKETPORT). Tested with the RocketPort EXPRESS Octa DB9 and Quad DB9. Also added an old RocketPort 8J PCI card to the same system to verify that rocket.c and rp2.c coexist peacefully.

2013-01-178250/16?50: Add support for Broadcom TruManage redirected serial portStephen Hurd1-1/+2
Add support for the UART device present in Broadcom TruManage capable NetXtreme chips (ie: 5761m 5762, and 5725). This implementation has a hidden transmit FIFO, so running in single-byte interrupt mode results in too many interrupts. The UART_CAP_HFIFO capability was added to track this. It continues to reload the THR as long as the THRE and TSRE bits are set in the LSR up to a specified limit (1024 is used here).
