2018-05-02pinctrl: qcom: qdf2xxx: add support for new ACPI HID QCOM8002Timur Tabi
Newer versions of the firmware for the Qualcomm Datacenter Technologies QDF2400 restricts access to a subset of the GPIOs on the TLMM. To prevent older kernels from accidentally accessing the restricted GPIOs, we change the ACPI HID for the TLMM block from QCOM8001 to QCOM8002, and introduce a new property "gpios". This property is an array of specific GPIOs that are accessible. When an older kernel boots on newer (restricted) firmware, it will fail to probe. To implement the sparse GPIO map, we register all of the GPIOs, but fill in the data only for available GPIOs. This ensures that the driver cannot accidentally access an unavailable GPIO. The pinctrl-msm driver also scans the "gpios" property to determine which pins are available, and ensure that only those can be registered. Support for QCOM8001 is removed as there is no longer any firmware that implements it.

2018-05-02pinctrl: sunrisepoint: Align GPIO number space with WindowsMika Westerberg
It turns out that the Windows GPIO driver for Sunrisepoint PCH-H uses similar bank structure than it does for Cannon Lake with the exception that here the bank size is always 24 pins. Starting from pad group E the BIOS/Windows GPIO numbering does not match the hardware anymore but instead there are gaps to make each pad group ("bank") consume exactly 24 pins. Because of this Linux does not use correct pins for GpioIo/GpioIo resources exposed by the BIOS. This patch aligns the GPIO number space with BIOS/Windows to make sure the same numbering scheme is used in Linux as well following what we did already for Intel Cannon Lake.

2018-05-02pinctrl: cherryview: Associate IRQ descriptors to irqdomainMika Westerberg
When we dropped the custom Linux GPIO translation it resulted that the IRQ numbers changed slightly as well. Normally this would be fine because everyone is expected to use controller relative GPIO numbers and ACPI GpioIo/GpioInt resources. However, there is a certain set of Intel_Strago based Chromebooks where i8042 keyboard controller IRQ number is hardcoded be 182 (this is corrected with newer coreboot but the older ones still have the hardcoded Linux IRQ number). Because of this hardcoded IRQ number keyboard on those systems accidentally broke again. Fix this by iteratively associating IRQ descriptors to the chip irqdomain so that there are no gaps on those systems. Other systems are not affected.

git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic Pul removal of obsolete architecture ports from Arnd Bergmann: "This removes the entire architecture code for blackfin, cris, frv, m32r, metag, mn10300, score, and tile, including the associated device drivers. I have been working with the (former) maintainers for each one to ensure that my interpretation was right and the code is definitely unused in mainline kernels. Many had fond memories of working on the respective ports to start with and getting them included in upstream, but also saw no point in keeping the port alive without any users. In the end, it seems that while the eight architectures are extremely different, they all suffered the same fate: There was one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem, which was more costly than licensing newer off-the-shelf CPU cores from a third party (typically ARM, MIPS, or RISC-V). It seems that all the SoC product lines are still around, but have not used the custom CPU architectures for several years at this point. In contrast, CPU instruction sets that remain popular and have actively maintained kernel ports tend to all be used across multiple licensees. [ See the new nds32 port merged in the previous commit for the next generation of "one company in charge of an SoC line, a CPU microarchitecture and a software ecosystem" - Linus ] The removal came out of a discussion that is now documented at https://lwn.net/Articles/748074/. Unlike the original plans, I'm not marking any ports as deprecated but remove them all at once after I made sure that they are all unused. Some architectures (notably tile, mn10300, and blackfin) are still being shipped in products with old kernels, but those products will never be updated to newer kernel releases. After this series, we still have a few architectures without mainline gcc support: - unicore32 and hexagon both have very outdated gcc releases, but the maintainers promised to work on providing something newer. At least in case of hexagon, this will only be llvm, not gcc. - openrisc, risc-v and nds32 are still in the process of finishing their support or getting it added to mainline gcc in the first place. They all have patched gcc-7.3 ports that work to some degree, but complete upstream support won't happen before gcc-8.1. Csky posted their first kernel patch set last week, their situation will be similar [ Palmer Dabbelt points out that RISC-V support is in mainline gcc since gcc-7, although gcc-7.3.0 is the recommended minimum - Linus ]" This really says it all: 2498 files changed, 95 insertions(+), 467668 deletions(-) * tag 'arch-removal' of git://git.kernel.org/pub/scm/linux/kernel/git/arnd/asm-generic: (74 commits) MAINTAINERS: UNICORE32: Change email account staging: iio: remove iio-trig-bfin-timer driver tty: hvc: remove tile driver tty: remove bfin_jtag_comm and hvc_bfin_jtag drivers serial: remove tile uart driver serial: remove m32r_sio driver serial: remove blackfin drivers serial: remove cris/etrax uart drivers usb: Remove Blackfin references in USB support usb: isp1362: remove blackfin arch glue usb: musb: remove blackfin port usb: host: remove tilegx platform glue pwm: remove pwm-bfin driver i2c: remove bfin-twi driver spi: remove blackfin related host drivers watchdog: remove bfin_wdt driver can: remove bfin_can driver mmc: remove bfin_sdh driver input: misc: remove blackfin rotary driver input: keyboard: remove bf54x driver ...
2018-03-27pinctrl: qcom: Don't allow protected pins to be requestedStephen Boyd
Some qcom platforms make some GPIOs or pins unavailable for use by non-secure operating systems, and thus reading or writing the registers for those pins will cause access control issues and reset the device. With a DT/ACPI property to describe the set of pins that are available for use, parse the available pins and set the irq valid bits for gpiolib to know what to consider 'valid'. This should avoid any issues with gpiolib. Furthermore, implement the pinmux_ops::request function so that pinmux can also make sure to not use pins that are unavailable.

2018-03-27pinctrl: sunxi: add support for the Allwinner H6 main pin controllerIcenowy Zheng
The Allwinner H6 SoC has two pin controllers, one main controller (called CPUX-PORT in user manual) and one controller in CPUs power domain (called CPUS-PORT in user manual). This commit introduces support for the main pin controller on H6. The pin bank A and B are not wired out and hidden from the SoC's documents, however it's shown that the "ATE" (an AC200 chip co-packaged with the H6 die) is connected to the main SoC die via these pin banks. The information about these banks is just copied from the BSP pinctrl driver, but re-formatted to fit the mainline pinctrl driver format. The GPIO functions are dropped, as they're impossible to use -- except a GPIO&IRQ only pin (PB20) which might be the IRQ of ATE.

2018-03-26pinctrl/amd: poll InterruptEnable bits in enable_irqDaniel Kurtz
In certain cases interrupt enablement will be delayed relative to when the InterruptEnable bits are written. One example of this is when a GPIO's "debounce" logice is first enabled. After enabling debounce, there is a 900 us "warm up" period during which InterruptEnable[0] (bit 11) will read as 0 despite being written 1. During this time InterruptSts will not be updated, nor will interrupts be delivered, even if the GPIO's interrupt configuration has been written to the register. To work around this delay, poll the InterruptEnable bits after setting them to ensure interrupts have truly been enabled in hardware before returning from the irq_enable handler.
