From f7d519c1c7ba3da1b2e459fa1a82805c70544956 Mon Sep 17 00:00:00 2001 From: Julius Werner Date: Fri, 2 Sep 2016 23:48:10 -0700 Subject: [PATCH] rockchip/rk3399: Fix rkclk_init() to actually use PERILP1_PCLK_HZ This patch fixes a typo in the clock initialization code that caused the PERILP1_PCLK_HZ constant to be ignored and the clock to always run at the same speed as its parent (PERILP1_HCLK_HZ). Since we've done all our previous tests and validation with this bug, we should probably increase the value of the constant (that had not actually been used) to the value that we had been incorrectly using instead (which also makes effective SPI read times faster).
