+Subject: [PATCH] nvmem: qfprom: Mark core clk as optional
+
+On some platforms like sc7280 on non-ChromeOS devices the core clock
+cannot be touched by Linux so we cannot provide it. Mark it as optional
+as accessing qfprom for reading works without it but we still prohibit
+writing if we cannot provide the clock.
