From 4cd7a2f1aedb2008004e110d31ce831895139fa0 Mon Sep 17 00:00:00 2001 From: Peter Ujfalusi Date: Mon, 10 Sep 2012 13:46:22 +0300 Subject: mfd: twl-core: Add API to query the HFCLK rate CFG_BOOT register's HFCLK_FREQ field hold information about the used HFCLK frequency. Add possibility for users to get the configured rate based on this register. This register was configured during boot, without it the chip would not operate correctly, so we can trust on this information.
