A bit # later than usual because I was ironing out my own mistakes. I'm # holding some stuff back for the next kernel as a result, and this # should be a healthy and well tested batch. # # Core changes: # # - The gpiolib MMIO driver has been enhanced to handle two direction # registers, i.e. one register to set lines as input and one register # to set lines as output. It turns out some silicon engineer thinks # the ability to configure a line as input and output at the same # time makes sense, this can be debated but includes a lot of analog # electronics reasoning, and the registers are there and need to be # handled consistently. Unsurprisingly, we enforce the lines to be # either inputs or outputs in such schemes. # # - Send in the proper argument value to .set_config() dispatched to # the pin control subsystem. Nobody used it before, now someone does, # so fix it to work as expected. # # - The ACPI gpiolib portions can now handle pin bias setting (pull up # or pull down). This has been in the ACPI spec for years and we # finally have it properly integrated with Linux GPIOs. It was based # on an observation from Andy Schevchenko that Thomas Petazzoni's # changes to the core for biasing the PCA950x GPIO expander actually # happen to fit hand-in-glove with what the ACPI core needed. Such # nice synergies happen sometimes. # # New drivers: # # - A new driver for the Mellanox BlueField GPIO controller. This is # using 64bit MMIO registers and can configure lines as inputs and # outputs at the same time and after improving the MMIO library we # handle it just fine. Interesting. # # - A new IXP4xx proper gpiochip driver with hierarchical interrupts # should be coming in from the ARM SoC tree as well. # # Driver enhancements: # # - The PCA053x driver handles the CAT9554 GPIO expander. # # - The PCA053x driver handles the NXP PCAL6416 GPIO expander. # # - Wake-up support on PCA053x GPIO lines. # # - OMAP now does a nice asynchronous IRQ handling on wake-ups by # letting everything wake up on edges, and this makes runtime PM work # as expected too. # # Misc: # # - Several cleanups such as devres fixes. # # - Get rid of some languager comstructs that cause problems when # compiling with LLVMs clang. # # - Documentation review and update" # # * tag 'gpio-v5.2-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio: (85 commits) # gpio: Update documentation # docs: gpio: convert docs to ReST and rename to *.rst # gpio: sch: Remove write-only core_base # gpio: pxa: Make two symbols static # gpiolib: acpi: Respect pin bias setting # gpiolib: acpi: Add acpi_gpio_update_gpiod_lookup_flags() helper # gpiolib: acpi: Set pin value, based on bias, more accurately # gpiolib: acpi: Change type of dflags # gpiolib: Introduce GPIO_LOOKUP_FLAGS_DEFAULT # gpiolib: Make use of enum gpio_lookup_flags consistent # gpiolib: Indent entry values of enum gpio_lookup_flags # gpio: pca953x: add support for pca6416 # dt-bindings: gpio: pca953x: document the nxp,pca6416 # gpio: pca953x: add pcal6416 to the of_device_id table # gpio: gpio-omap: Remove conditional pm_runtime handling for GPIO interrupts # gpio: gpio-omap: configure edge detection for level IRQs for idle wakeup # tracing: stop making gpio tracing configurable # gpio: pca953x: Configure wake-up path when wake-up is enabled # gpio: of: Optimize quirk checks # gpio: mmio: Drop bgpio_dir_inverted # ... # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-gcc --version # < /opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux-ld --version # < git log --format=%s --max-count=1 8148c17b179d8acad190551fe0fb90d8f5193990 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_ppc40x_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- ppc40x_defconfig # make -s -j 120 ARCH=powerpc O=/kisskb/build/linus_ppc40x_defconfig_powerpc-gcc4.6 CROSS_COMPILE=/opt/cross/kisskb/gcc-4.6.3-nolibc/powerpc-linux/bin/powerpc-linux- :1388:2: warning: #warning syscall open_tree not implemented [-Wcpp] :1391:2: warning: #warning syscall move_mount not implemented [-Wcpp] :1394:2: warning: #warning syscall fsopen not implemented [-Wcpp] :1397:2: warning: #warning syscall fsconfig not implemented [-Wcpp] :1400:2: warning: #warning syscall fsmount not implemented [-Wcpp] :1403:2: warning: #warning syscall fspick not implemented [-Wcpp] /kisskb/src/kernel/printk/printk.c: In function 'devkmsg_sysctl_set_loglvl': /kisskb/src/kernel/printk/printk.c:187:16: warning: 'old' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c: In function 'proc_reg_open': /kisskb/src/include/linux/list.h:65:12: warning: 'pdeo' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/fs/proc/inode.c:331:21: note: 'pdeo' was declared here /kisskb/src/drivers/tty/serial/8250/8250_core.c: In function 'univ8250_release_irq': /kisskb/src/drivers/tty/serial/8250/8250_core.c:247:18: warning: 'i' may be used uninitialized in this function [-Wuninitialized] /kisskb/src/drivers/tty/serial/8250/8250_core.c:227:19: note: 'i' was declared here INFO: Uncompressed kernel (size 0x5414d4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5414d4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5414d4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.1.0-g8148c17b179d Created: Sun May 12 01:31:35 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2669039 Bytes = 2606.48 KiB = 2.55 MiB Load Address: 00600000 Entry Point: 00601758 INFO: Uncompressed kernel (size 0x530e60) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.1.0-g8148c17b179d Created: Sun May 12 01:31:35 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2669537 Bytes = 2606.97 KiB = 2.55 MiB Load Address: 00600000 Entry Point: 006019cc INFO: Uncompressed kernel (size 0x5414d4) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.1.0-g8148c17b179d Created: Sun May 12 01:31:35 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2638388 Bytes = 2576.55 KiB = 2.52 MiB Load Address: 00000000 Entry Point: 00000000 Completed OK # rm -rf /kisskb/build/linus_ppc40x_defconfig_powerpc-gcc4.6 # Build took: 0:00:17.466395
