* esp32s3 copy for esp32s2 * idf's rtc_sleep_pd * Add the new NRX, FE & FE2 peripherals from the PAC * Went through rtc_sleep_init -> apply * Add all else statements of idf's rtc_sleep_init and made the style match the cpp code more for easier checking * Finish checking/copying base_settings * Checked flags in apply * Allow base_settings * Remove unused variables * Reenable rtc_peri for Ext1WakeupSource * Correct comment. Probably copy-pasted and still present in esp32s3 * Remove TODO comments * Add the esp32s2 sleep work to the changelog * Add esp32s2 to qa-test where applicable * update pacs and update after rebase * changelog * provide missing ROM functions * Update PACs * review comments and cleanup * review * Fix wrong cfg condition --------- Co-authored-by: mennovf <mennovanfrachem@hotmail.com>
