* stm32wl: add hardware RTC support infrastructure Wires the STM32WL chip's internal RTC (running off the LSE 32.768kHz crystal) into meshtastic's existing time-of-day framework (perhapsSetRTC()/readFromRTC()), following the same pattern already used for I2C RTC chips (RV3028, PCF8563/85063, RX8130CE). LSE is started and polled manually before ever calling into the STM32RTC library, with our own bounded timeout - the library's own internal LSE startup path has no bounded fallback and hangs forever via Error_Handler() if the crystal never locks, so this is required for a board with a missing/faulty crystal to boot normally rather than hang. Gated behind a new HAS_LSE variant flag (currently unset everywhere, so this is inert until a variant opts in - see follow-up commit). Signed-off-by: Andrew Yong <me@ndoo.sg> Assisted-by: Claude Sonnet 5 <noreply@anthropic.com> * gps: qualify RTC.h includes to avoid case-insensitive filesystem collision with STM32RTC The stm32duino STM32RTC library (added to lib_deps in a follow-up commit) ships its own src/rtc.h. On case-insensitive filesystems (the macOS default), an unqualified #include "RTC.h"/<RTC.h> from any file outside src/gps/ resolves to the library's rtc.h instead of src/gps/RTC.h, since PlatformIO's LDF puts lib_deps include paths ahead of the project's own -Isrc/gps. Qualify every include as gps/RTC.h so it can't collide with any same-named header a future dependency might ship, regardless of filesystem case sensitivity. Purely mechanical, no behavior change. Signed-off-by: Andrew Yong <me@ndoo.sg> Assisted-by: Claude Sonnet 5 <noreply@anthropic.com> * stm32wl(rak3172): enable hardware RTC support Opts rak3172 into the HAS_LSE infrastructure added previously: sets STM32WL_LSE_DRIVE to a conservative default and pulls in the STM32RTC library. rak3172 has ~63KB flash headroom going in; build-verified at 76.7% flash usage after this change (up from a 73.8% baseline), well within budget. wio-e5 is not opted in here despite sharing the same STM32WLE5 chip - it's already at 96.8% flash usage today (GPS + I2C sensor support compiled in, unlike rak3172), leaving too little headroom to safely add STM32RTC without first trimming something else. Signed-off-by: Andrew Yong <me@ndoo.sg> Assisted-by: Claude Sonnet 5 <noreply@anthropic.com> * stm32wl: add docstrings for LSE/RTC setup functions Addresses CodeRabbit's docstring coverage check on PR #10961. Signed-off-by: Andrew Yong <me@ndoo.sg> Assisted-by: Claude Sonnet 5 <noreply@anthropic.com> * stm32wl: address CodeRabbit nitpicks on PR #10961 - Brace the single-statement HAS_LSE branch in perhapsSetRTC() to match the sibling readFromRTC() branch's style. - Quote the RTC.h include in PhoneAPI.cpp for consistency with every other qualified include site.
