Hi Linus, the following is the bulk of GPIO changes for v5.4. The main information chunk about the updates is in the signed tag as always. This cycle has been pretty lively. You will notice that I merged in v5.3-rc7 at a late point. This was because the conflicts were really hairy between the -rc:s and the bulk of development: the kind where there is a variable rename in one branch and independent reshuffling of code in the other. This took me some substantial time to sort out, despite both changes being my own. I don't know if I'm especially bad at resolving conflicts but after failing to construct a branch for -next several times I just sat down and resolved the conflicts toward -rc7 once and for all. I still had to fix it up with a patch on top. Changes hitting Unicore and FMC in MAINTAINERS are eplained in the signed tag as well. Please pull it in! Yours, Linus Walleij The following changes since commit 089cf7f6ecb266b6a4164919a2e69bd2f938374a: Linux 5.3-rc7 (2019-09-02 09:57:40 -0700) are available in the Git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio.git tags/gpio-v5.4-1 for you to fetch changes up to 11c43bb022b373d2fdb84950ebf1911362f3f010: gpiolib: of: add a fallback for wlf,reset GPIO name (2019-09-12 10:29:17 +0100) ---------------------------------------------------------------- This is the bulk of changes in the GPIO subsystem for the v5.4 kernel cycle. Core changes: - Support hierarchical GPIO irqchips. We now have three consumers that can use this: Intel IXP4xx, ThunderX and Qualcomm SPMI GPIO (in the pinctrl subsystem). The support code has been long in the making and hashed out so it should be easily adaptable for all hierarchical irqchip parents. The code only gets compiled in if hierarchical irqchip is used at the topmost irq controller at least, as the hierarchical irqchip requires strict hierarchy all the way up in the system. - Determine the need for a "valid_mask" for GPIO lines on the gpio_chip and conversely for the "valid_mask" for the GPIO interrupt chip interrupt lines by looking for a .init_valid_mask() callback in the main chip or GPIO interrupt chip respectively. Allocate it with bitmap_alloc(). - Isolate the device tree/open firmware GPIO description code out in its own file properly. - Isolate the ACPI GPIO description code out in its own file properly. - Drop a whole lot of #ifdef:s in the main includes: it does not hurt to keep the include items around, and we get quicker and clearer compile failures if the appropriate kernel symbols are not selected for drivers. New/deleted drivers: - New driver for Aspeed SGPIO. - The KS8695 driver is deleted as the platform gets deleted from arch/arm in this kernel cycle. - The Cirrus Logic Madera driver now supports CS47L92 and CS47L15. - The Freescale MPC8xxx now supports LS1028A and LS1088A. Driver improvements: - We pass the GPIO irqchip intialization by directly filling in the struct instead of using set-up functions (the new way) for Intel MID, Lynxpoint, Merrifield, XLP, HLWD, Aspeed, ZX, VF610, TQMX86, MT7621, Zynq and EP93xx. Out-of-band changes: - Fix a GPIO header inclusion in Unicore - no response from maintainer. - Drop FMC subsystem from MAINTAINERS - was deleted in the GPIO tree last cycle so let's mop up the shards.
