From cdfc2e2086bf9c465f44e2db25561373b084a113 Mon Sep 17 00:00:00 2001 From: Colin Ian King Date: Wed, 23 Oct 2019 12:28:09 +0100 Subject: clk: sunxi-ng: a80: fix the zero'ing of bits 16 and 18 The zero'ing of bits 16 and 18 is incorrect. Currently the code is masking with the bitwise-and of BIT(16) & BIT(18) which is 0, so the updated value for val is always zero. Fix this by bitwise and-ing value with the correct mask that will zero bits 16 and 18.
