git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik into arm/soc This modernizes the IXP4xx platform and adds initial Device Tree Support. We migrate to MULTI_IRQ_HANDLER, bumps the IRQs to offset 16, converts to SPARSE_IRQ, then we add proper subsystem drivers in each subsystem for irqchip, GPIO and clocksource and switch over to using these new drivers. Next we modernize the NPE and QMGR drivers and push them down into drivers/soc. This has been tested on the IXP4xx NSLU2 and the Gateworks GW2358-4. * tag 'ixp4xx-for-armsoc' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-nomadik: (31 commits) ARM: dts: Add queue manager and NPE to the IXP4xx DTSI soc: ixp4xx: qmgr: Add DT probe code soc: ixp4xx: qmgr: Add DT bindings for IXP4xx qmgr soc: ixp4xx: npe: Add DT probe code soc: ixp4xx: Add DT bindings for IXP4xx NPE soc: ixp4xx: qmgr: Pass resources soc: ixp4xx: Remove unused functions soc: ixp4xx: Uninline several functions soc: ixp4xx: npe: Pass addresses as resources ARM: ixp4xx: Turn the QMGR into a platform device ARM: ixp4xx: Turn the NPE into a platform device ARM: ixp4xx: Move IXP4xx QMGR and NPE headers ARM: ixp4xx: Move NPE and QMGR to drivers/soc ARM: dts: Add some initial IXP4xx device trees ARM: ixp4xx: Add device tree boot support ARM: ixp4xx: Add DT bindings gpio: ixp4xx: Add OF probing support gpio: ixp4xx: Add DT bindings clocksource/drivers/ixp4xx: Add OF initialization support clocksource/drivers/ixp4xx: Add DT bindings ...

2019-04-28ARM: ep93xx: move pinctrl interfaces into include/linux/socArnd Bergmann1-2/+1
ep93xx does not have a proper pinctrl driver, but does things ad-hoc through mach/platform.h, which is also used for setting up the boards. To avoid using mach/*.h headers completely, let's move the interfaces into include/linux/soc/. This is far from great, but gets the job done here, without the need for a proper pinctrl driver.

2019-04-28ARM: ep93xx: keypad: stop using mach/platform.hArnd Bergmann2-5/+2
We can communicate the clock rate using platform data rather than setting a flag to use a particular value in the driver, which is cleaner and avoids the dependency. No platform in the kernel currently defines the ep93xx keypad device structure, so this is a rather pointless excercise. Any out of tree users are probably dead now, but if not, they have to change their platform code to match the new platform_data structure.

2019-04-03Input: evdev - use struct_size() in kzalloc() and vzalloc()Gustavo A. R. Silva1-4/+3
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; size = sizeof(struct foo) + count * sizeof(struct boo); instance = kzalloc(size, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL); Notice that, in this case, variable size is not necessary, hence it is removed.

2019-02-18Input: i8042 - rework DT node name comparisonsRob Herring1-11/+10
Convert string compares of DT node names to use of_node_name_eq helper instead. For the root node on SUN DT, we need to retrieve the 'name' property as it is the rare case where the 'name' property and node name differ. With both changes, it removes direct access to the node name pointer. While at it, convert the open coded loop to use for_each_child_of_node().

2019-02-17Merge branch 'for-linus' of ↵Linus Torvalds11-101/+75
git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input Pull input fixes from Dmitry Torokhov: - tweaks to Elan drivers (both PS/2 and I2C) to support new devices. Also revert of one of IDs as that device should really be driven by i2c-hid + hid-multitouch - a few drivers have been switched to set_brightness_blocking() call because they either were sleeping the their set_brightness() implementation or used workqueue but were not canceling it on unbind. - ps2-gpio and matrix_keypad needed to [properly] flush their works to avoid potential use-after-free on unbind. - other miscellaneous fixes. * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: Input: elan_i2c - add ACPI ID for touchpad in Lenovo V330-15ISK Input: st-keyscan - fix potential zalloc NULL dereference Input: apanel - switch to using brightness_set_blocking() Revert "Input: elan_i2c - add ACPI ID for touchpad in ASUS Aspire F5-573G" Input: qt2160 - switch to using brightness_set_blocking() Input: matrix_keypad - use flush_delayed_work() Input: ps2-gpio - flush TX work when closing port Input: cap11xx - switch to using set_brightness_blocking() Input: elantech - enable 3rd button support on Fujitsu CELSIUS H780 Input: bma150 - register input device after setting private data Input: pwm-vibra - stop regulator after disabling pwm, not before Input: pwm-vibra - prevent unbalanced regulator Input: snvs_pwrkey - allow selecting driver for i.MX 7D

Remove a leftover spinlock. This was required back when mod_delayed_work() did not exist, and had to be implemented with a cancel + queue. See commit e7c2f967445d ("workqueue: use mod_delayed_work() instead of __cancel + queue") schedule_delayed_work() and mod_delayed_work() can now be used concurrently.
