From 4e85e535e6cc6e8a96350e8ee684d0f22eb8629e Mon Sep 17 00:00:00 2001 From: Nicolas Saenz Julienne Date: Wed, 12 Jun 2019 20:24:54 +0200 Subject: clk: bcm283x: add driver interfacing with Raspberry Pi's firmware Raspberry Pi's firmware offers an interface though which update it's clock's frequencies. This is specially useful in order to change the CPU clock (pllb_arm) which is 'owned' by the firmware and we're unable to scale using the register interface provided by clk-bcm2835.
