Thank you!
Hi Linus, here is the big pull request for GPIO for v5.2. 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. I merged in v5.1-rc3 at one point to get rid of some nasty merge conflicts with one of the bigger fixes that went in in the early rcs. Other than that it is business as usual and a not very busy kernel cycle this time. Please pull it in! Yours, Linus Walleij The following changes since commit 79a3aaa7b82e3106be97842dedfd8429248896e6: Linux 5.1-rc3 (2019-03-31 14:39:29 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git tags/gpio-v5.2-1 for you to fetch changes up to 0fbee1df2078fa1f61e2da14f51ceb357c79ae69: gpio: Update documentation (2019-05-07 16:32:12 +0200) ---------------------------------------------------------------- This is the bulk of the GPIO changes for the v5.2 kernel cycle: 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.
