* ps2_mouse on ARM: an interrupt-version of the ps2-mouse code ported to ARM/chibios * ps2_mouse on ARM: link EXT callback-channel selection to the user defined PS2_LINE_CLOCK * ps2_mouse on ARM: replace DELAY_X defines with hardware-agnostic wait_X * ps2_mouse on ARM: replace chibios-specific defines for the pins/lines with defines from quantum/config_common.h and drop the '_LINE' component from teh define name * ps2_mouse on ARM: expose the software-intterupt port as a user editable define * Update docs/feature_ps2_mouse.md Co-Authored-By: Hugo van Kemenade <hugovk@users.noreply.github.com> * Update feature_ps2_mouse.md * use a define to deduce the PS_DATA_PORT instead * reduce all-zero extcfg to oneliner * ps2_mouse: use generic wait instead of avr-delay * Update docs/feature_ps2_mouse.md * ps2_mouse: changes for new chibios version (17.6.0 -> 19.1.0) replacing the legacy externa-interrupt driver with pal-callbacks * ps2_mouse: use PLATFORM_KEY Co-Authored-By: Joel Challis <git@zvecr.com> * ps2_mouse: clang-format corrections * ps2_mouse: add systemlocks using the chibios equivalent to AVRs cli: chSys[Unl|L]ock Co-authored-by: Johannes <you@example.com> Co-authored-by: Hugo van Kemenade <hugovk@users.noreply.github.com> Co-authored-by: Joel Challis <git@zvecr.com>
