-Subject: [PATCH] firmware: raspberrypi: Introduce vl805 init routine
-
-On the Raspberry Pi 4, after a PCI reset, VL805's firmware may either be
-loaded directly from an EEPROM or, if not present, by the SoC's
-VideCore. The function informs VideCore that VL805 was just reset, or
-requests for a probe defer.
-
-Based on Tim Gover's downstream implementation.
