Subject: [PATCH 0/2] Keep PLL power on
Date: Tue, 21 Feb 2023 21:01:08 +0800 [thread overview]
Message-ID: <20230221130110.29656-1-dylan_hung@aspeedtech.com> (raw)
There are several PLLs in AST2600 that provide clock sources for various
hardware blocks. According to the PLL vendor, the setting sequence was
incorrect, since the PLL power should kept on during initialization.
This patch series fixes the PLL setting sequence, including the MPLL in
the DRAM driver and the others in the clock driver.
