refactor(core): display driver suspend API improvement

This is a code cleanup change that moves decision-making about how deeply to put the screen to sleep out of the display driver and into a higher-level suspend module. It does not add or remove security protections; it only reorganizes whic…

tests(core): add T3W1 tap-to-wake click tests

This commit only adds new automated tests for the 'tap to wake' feature on the T3W1 hardware model. It does not change any firmware code that runs on the device, so it cannot introduce a security vulnerability or fix one. The tests verify …

feat(core): add T3W1 touch wakeup emulation support

This commit adds emulator-only support for a new Trezor device (T3W1) to wake from a simulated low-power sleep state when the user taps the emulated touchscreen. It only affects the software emulator build, not real hardware, and does not …

feat(core): wire USE_TOUCH_WAKEUP build flag for T3W1

This commit is a straightforward build-system wiring change for the Trezor T3W1 hardware wallet. It enables a feature called USE_TOUCH_WAKEUP, which lets the device wake from a low-power suspend state when the touch screen is touched. The …

feat(core): expose touch_wakeup_set/get_enabled to MicroPython via trezorio.touch

This commit simply adds a way for the device's Python code to ask whether the hardware supports waking from sleep by touch, and to turn that feature on or off. It is a normal feature-exposure change with no security bug visible in the diff.

feat(core): TS7 display refresh rate scaling and configuration optimization

This commit changes how the Trezor hardware wallet's display is driven, mainly to save battery. It adds the ability to switch between 60 Hz and 30 Hz refresh rates depending on whether the screen is showing animations or a static image. It…

No security-relevant signals found in commit message or diff.Change is described by the vendor as power-consumption optimization and configuration formalization.Refresh-rate scaling runs in interrupt context with IRQ locks and busy-wait timeout, which could affect real-time behavior but is not shown to be exploitable.
