From 9d25207aaf93cb8052910f11fc1febd7865fb6e9 Mon Sep 17 00:00:00 2001 From: Taniya Das Date: Fri, 3 Apr 2020 21:37:27 +0530 Subject: sc7180: clock: Define the UART frequency for QUPV3 The frequency to be used by UART client is 7.3728MHz, thus define it in the clock header to be used by the driver. Tested: UART frequency request by client driver.
