/* * ums9117: sec-storage: Add polling retry for PMIC vdd_core ramp delay * * This driver top change works around a silicon errata (UNI-ER-9117-03) * where the secure storage MMIO returns stale data on pre-prod spin 2.1. * Polling the SEC_STATUS_REG for PMIC_READY (bit 7) adds max 2ms latency. * Safe for production as retry exits early on good silicon. * * Signed-off-by: Leo Zhang <leo.zhang@unisoc.com> */
Down in the silicon, UMS9117 looked at his ledger. The temperature was stable. The data was delivered. unisoc ums9117 driver top
