2022-11-03tty: serial: use uart_port_tx_limited()Jiri Slaby (SUSE)
uart_port_tx_limited() is a new helper to send characters to the device. Use it in these drivers. mux.c also needs to define tx_done(). But I'm not sure if the driver really wants to wait for all the characters to dismiss from the HW fifo at this code point. Hence I marked this as FIXME.

Pull ARM SoC updates from Arnd Bergmann: "The main changes this time are for the organization of the Kconfig files, introducing per-vendor top-level options on arm64 to match those on arm32, and making the platform selection on arm32 more uniform, in particular for the remaining StrongARM platforms that still have a couple of special cases compared to the more recent ones. I also did a cleanup of the old Footbridge platform, which was the last holdout for the phys_to_dma()/dma_to_phys() interface that is now completely gone from arm32, completing work started by Christoph Hellwig" * tag 'arm-soc-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (21 commits) ARM: aspeed: Kconfig: Fix indentation ARM: Drop CMDLINE_* dependency on ATAGS ARM: Drop CMDLINE_FORCE dependency on !ARCH_MULTIPLATFORM ARM: s3c: remove orphan declarations from arch/arm/mach-s3c/devs.h pxa: Drop if with an always false condition ARM: orion: fix include path ARM: shmobile: Drop selecting SOC_BUS arm64: renesas: Drop selecting SOC_BUS ARM: disallow PCI with MMU=n again ARM: footbridge: remove custom DMA address handling MAINTAINERS: Add BCM4908 maintainer to BCMBCA entry ARM: footbridge: move isa-dma support into footbridge ARM: footbridge: remove leftover from personal-server ARM: footbridge: remove addin mode arm64: Kconfig.platforms: Group NXP platforms together arm64: Kconfig.platforms: Re-organized Broadcom menu ARM: make ARCH_MULTIPLATFORM user-visible ARM: fix XIP_KERNEL dependencies ARM: Kconfig: clean up platform selection ARM: simplify machdirs/platdirs handling ...

git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc Pull ARM driver updates from Arnd Bergmann: "The drivers branch for 6.1 is a bit larger than for most releases. Most of the changes come from SoC maintainers for the drivers/soc subsystem: - A new driver for error handling on the NVIDIA Tegra 'control backbone' bus. - A new driver for Qualcomm LLCC/DDR bandwidth measurement - New Rockchip rv1126 and rk3588 power domain drivers - DT binding updates for memory controllers, older Rockchip SoCs, various Mediatek devices, Qualcomm SCM firmware - Minor updates to Hisilicon LPC bus, the Allwinner SRAM driver, the Apple rtkit firmware driver, Tegra firmware - Minor updates for SoC drivers (Samsung, Mediatek, Renesas, Tegra, Qualcomm, Broadcom, NXP, ...) There are also some separate subsystem with downstream maintainers that merge updates this way: - Various updates and new drivers in the memory controller subsystem for Mediatek and Broadcom SoCs - Small set of changes in preparation to add support for FF-A v1.1 specification later, in the Arm FF-A firmware subsystem - debugfs support in the PSCI firmware subsystem" * tag 'arm-drivers-6.1' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc: (149 commits) ARM: remove check for CONFIG_DEBUG_LL_SER3 firmware/psci: Add debugfs support to ease debugging firmware/psci: Print a warning if PSCI doesn't accept PC mode dt-bindings: memory: snps,dw-umctl2-ddrc: Extend schema with IRQs/resets/clocks props dt-bindings: memory: snps,dw-umctl2-ddrc: Replace opencoded numbers with macros dt-bindings: memory: snps,dw-umctl2-ddrc: Use more descriptive device name dt-bindings: memory: synopsys,ddrc-ecc: Detach Zynq DDRC controller support soc: sunxi: sram: Add support for the D1 system control soc: sunxi: sram: Export the LDO control register soc: sunxi: sram: Save a pointer to the OF match data soc: sunxi: sram: Return void from the release function soc: apple: rtkit: Add apple_rtkit_poll soc: imx: add i.MX93 media blk ctrl driver soc: imx: add i.MX93 SRC power domain driver soc: imx: imx8m-blk-ctrl: Use genpd_xlate_onecell soc: imx: imx8mp-blk-ctrl: handle PCIe PHY resets soc: imx: imx8m-blk-ctrl: add i.MX8MP VPU blk ctrl soc: imx: add i.MX8MP HDMI blk ctrl HDCP/HRV_MWR soc: imx: add icc paths for i.MX8MP hsio/hdmi blk ctrl soc: imx: add icc paths for i.MX8MP media blk ctrl ...
2022-09-30serial: cpm_uart: Don't request IRQ too early for console portChristophe Leroy
The following message is seen during boot and the activation of console port gets delayed until normal serial ports activation. [ 0.001346] irq: no irq domain found for pic@930 ! The console port doesn't need irq, perform irq reservation later, during cpm_uart probe. While at it, don't use NO_IRQ but 0 which is the value returned by irq_of_parse_and_map() in case of error. By chance powerpc's NO_IRQ has value 0 but on some architectures it is -1.

port->lock is unlocked in each branch in altera_jtaguart_console_putc(), so do it before the "if". "status" needs not be under the lock, as the register was already read.

2022-09-30tty: serial: unify TX space reads under altera_jtaguart_tx_space()Jiri Slaby
TX space reads from the control register are performed in various forms on 4 places in altera_jtaguart. Unify all those and do the read and masking on a single place. The new helper altera_jtaguart_tx_space() uses FIELD_GET(), so we can drop ALTERA_JTAGUART_CONTROL_WSPACE_OFF now.

FIELD_GET() can do the job smarter and more readable. We don't even need ASCFSTAT_TXFREEOFF. So switch to the former and remove the latter.
