Subject: [PATCH 1/2] clk: qoriq: add clock configuration for ls1088a soc
Date: Thu, 6 Apr 2017 10:21:22 +0800 [thread overview]
Message-ID: <1491445283-13053-1-git-send-email-andy.tang@nxp.com> (raw)
Clock on ls1088a chip takes primary clocking input from the external
SYSCLK signal. The SYSCLK input (frequency) is multiplied using
multiple phase locked loops (PLL) to create a variety of frequencies
which can then be passed to a variety of internal logic, including
cores and peripheral IP modules.
