[PATCH 1/4] ARM: dts: stm32: split sdram pin & timing parameter into specific board dts

Thu Mar 11 07:43:57 CET 2021
From: dillon min <dillon.minfei at gmail.com>
As different boards has their own sdram hw connection, mount different
sdram modules, so move sdram timing parameter and pin configuration
to their board device tree.
