Pull input updates from Dmitry Torokhov: - support for NT36672A touchscreen added to novatek-nvt-ts driver - a change to ads7846 driver to prevent XPT2046 from locking up - a change switching platform input dirves back to using remove() method (from remove_new()) - updates to a number of input drivers to use the new cleanup facilities (__free(...), guard(), and scoped-guard()) which ensure that the resources and locks are released properly and automatically - other assorted driver cleanups and fixes. * tag 'input-for-v6.13-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (109 commits) Input: mpr121 - use devm_regulator_get_enable_read_voltage() Input: sun4i-lradc-keys - don't include 'pm_wakeup.h' directly Input: spear-keyboard - don't include 'pm_wakeup.h' directly Input: cypress-sf - constify struct i2c_device_id Input: ads7846 - increase xfer array size in 'struct ser_req' Input: fix the input_event struct documentation Input: i8042 - fix typo dublicate to duplicate Input: ads7846 - add dummy command register clearing cycle Input: cs40l50 - fix wrong usage of INIT_WORK() Input: introduce notion of passive observers for input handlers Input: maple_keyb - use guard notation when acquiring mutex Input: locomokbd - use guard notation when acquiring spinlock Input: hilkbd - use guard notation when acquiring spinlock Input: synaptics-rmi4 - switch to using cleanup functions in F34 Input: synaptics - fix a typo dt-bindings: input: rotary-encoder: Fix "rotary-encoder,rollover" type Input: omap-keypad - use guard notation when acquiring mutex Input: imagis - fix warning regarding 'imagis_3038_data' being unused Input: userio - remove unneeded semicolon Input: sparcspkr - use cleanup facility for device_node ...

Input: elan_i2c - switch to using cleanup functions

Start using __free() and guard() primitives to simplify the code and error handling. This makes the code more compact and error handling more robust by ensuring that locks are released in all code paths when control leaves critical section and all allocated memory is freed.

move asm/unaligned.h to linux/unaligned.h

2024-10-02T21:23:23Z

asm/unaligned.h is always an include of asm-generic/unaligned.h; might as well move that thing to linux/unaligned.h and include that - there's nothing arch-specific in that header. auto-generated by the following: for i in `git grep -l -w asm/unaligned.h`; do sed -i -e "s/asm\/unaligned.h/linux\/unaligned.h/" $i done for i in `git grep -l -w asm-generic/unaligned.h`; do sed -i -e "s/asm-generic\/unaligned.h/linux\/unaligned.h/" $i done git mv include/asm-generic/unaligned.h include/linux/unaligned.h git mv tools/include/asm-generic/unaligned.h tools/include/linux/unaligned.h sed -i -e "/unaligned.h/d" include/asm-generic/Kbuild sed -i -e "s/__ASM_GENERIC/__LINUX/" include/linux/unaligned.h tools/include/linux/unaligned.h

Input: elan_i2c - fix firmware update on newer ICs

The argument to iap page type command depends on the firmware page size. Fixes: bfd9b92bc8f9 ("Input: elan_i2c - handle firmware updated on newer ICs") Signed-off-by: Jingle Wu Signed-off-by: Dmitry Torokhov

Input: elan_i2c - add support for high resolution reports

2020-07-21T17:11:18Z

Newer controllers (identified as "pattern" version 2) send higher resolution reports, with 16-bit X and Y coordinates (previous generations used 12-bit values). These new high resolution reports use report ID of 0x60. SMbus controllers use the same buffer size for both the new and old reports, and because of that high resolution reports no longer carry area of contact data with SMbus.

Input: elan_i2c - do not constantly re-query pattern ID

2020-07-21T00:35:31Z

We do not need to constantly re-query pattern ID, we can instead query it once and then pass to methods that need it. Signed-off-by: Dmitry Torokhov

Input: elan_i2c - handle firmware updated on newer ICs

2020-07-18T00:36:01Z

Newer ICs with IC type value starting with 0x0D and newer bootloader code use 128-byte firmware pages. Their bootloader also needs to be switched to proper mode before executing firmware update. Signed-off-by: Jingle Wu Signed-off-by: Dmitry Torokhov

Input: elan_i2c - fix detecting IAP version on older controllers

2020-07-18T00:36:00Z

Older controllers in bootloader mode need a different command to retrieve the IAP version. Signed-off-by: Jingle Wu Link: https://lore.kernel.org/r/20200714105641.15151-1-jingle.wu@emc.com.tw Signed-off-by: Dmitry Torokhov

Input: elan_i2c - handle devices with patterns above 1

2020-07-18T00:35:59Z

Extend fetching and parsing parameters of the controllers to devices with "patterns" above 1 (which currently should be handled in the same fashion as devices with pattern 1). Signed-off-by: Jingle Wu Signed-off-by: Dmitry Torokhov
