Subject: [PATCH v3 0/1] sunxi: H616: add LPDDR4 support
Date: Sat, 4 Nov 2023 09:22:47 +0300 [thread overview]
Message-ID: <20231104062248.32938-1-iuncuim@gmail.com> (raw)
From: iuncuim <iuncuim@gmail.com>
At the moment, the driver only supports DDR3 and LPDDR3 memory.
Add support for a new type DRAM.
These changes have been successfully tested by me with orangepi
zero3 4GB (DRAM: Rayson RS1G32LO4D2BDS-53BT).
This patch should be applied after this:

Changes from v2:
* added default value for TPR6 parameter
* added panic for unsupported DRAM types in switch/case conditions
* added new line at the end of the timings file, changed the description
* added a few small missing parts obtained from boot0

Changes from v1:
* replaced the phy_init array with one compatible with opizero3
* added DRAM TPR6 parameter
* adaptation to new mctl_phy_configure_odt()
* added timings for the board orangepi zero3 4GB
