* Disable USART in sleep * Restore UART state on suspend/resume * FuriHal: Enable stop mode and add insomnia to I2C and SPI * Remove IDLE interrupt * FuriHal: add FPU isr and disable all FPU interrupt, add core2 stop mode configuration on deep sleep * FuriHal: tie stop mode debug with debug rtc flag * FuriHal: adjust flash latency on clock switch, tie mcu debug with RTC debug flag * FuriHal: move resource init to early stage * Add EXTI pending check, enable debug traps with compile-time flag * Wrap sleep debug functions in conditional compilation * Remove erroneous changed * Do not use CSS, remove it from everywhere * Enable/disable USB on VBUS connect (prototype) * FuriHal: add LPMS and DEEPSLEEP magic, workaround state inconsistency between cores * FuriHal: honor c1 LMPS * USB mode switch fix * Applications: add flags and insomnia bypass system * Correct spelling * FuriHal: cleanup insomnia usage, reset sleep flags on wakeup, add shutdown api * FuriHal: extra check on reinit request * FuriHal: rename gpio_display_rst pin to gpio_display_rst_n * FuriHal: add debug HAL * FuriHal: add some magic to core2 reload procedure, fix issue with crash on ble keyboard exit * FuriHal: cleanup ble glue, add BLE_GLUE_DEBUG flag * FuriHal: ble reinit API, move os timer to LPTIM1 for deep sleep capability, shutdown that works * FuriHal: take insomnia while shutdown * Remove USB switch on/off on VBUS change * Better tick skew handling * Improve tick consistency under load * Add USB_HP dummy IRQ handler * Move interrupt check closer to sleep * Clean up includes * Re-enable Insomnia globally * FuriHal: enable CSS * FuriHal: remove questionable core2 clock shenanigans * FuriHal: use core1 RCC registers in idle timer config * FuriHal: return back CSS handlers, add lptim isr dispatching Co-authored-by: Aleksandr Kutuzov <alleteam@gmail.com> Co-authored-by: nminaylov <nm29719@gmail.com>
