[Qemu-devel] [PATCH v2 4/9] i.MX: Add the CLK_IPG_HIGH clock |
Date: |
Mon, 8 Feb 2016 23:08:17 +0100 |
EPIT, GPT and other i.MX timers are using "abstract" clocks among which
a CLK_IPG_HIGH clock.
On i.MX25 and i.MX31 CLK_IPG and CLK_IPG_HIGH are mapped to the same clock
but on other SOC like i.MX6 they are mapped to distinct clocks.
This patch add the CLK_IPG_HIGH to prepare for SOC where these 2 clocks are
different.
