From 9ca07ebbac3c94974db75e25004203289d9013bc Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Tue, 24 Nov 2015 13:31:17 -0700 Subject: dm: timer: Support 64-bit counter There are timers with a 64-bit counter value but current timer uclass driver assumes a 32-bit one. Modify timer_get_count() to ask timer driver to always return a 64-bit counter value, and provide an inline helper function timer_conv_64() to handle the 32-bit/64-bit conversion automatically.
