From 79fcbde8eb57a0dfc9761c4ba167186843d7a707 Mon Sep 17 00:00:00 2001 From: Jun Nie Date: Wed, 8 May 2019 14:38:31 +0800 Subject: pico-imx7d: Correct uart clock root Correct uart clock root ID. Incorrect ID may result the clock is gated because rate value 0 is returned in imx_get_uartclk() The ID can be ignored if CONFIG_SKIP_LOWLEVEL_INIT is not enabled because init_clk_uart() will enable all uart clocks in that case.
