Thanks to - YouMin Chen - Akash Gajjar - Kever Yang for supporting all the help on this work. Changes for v3: - squash set_rate code in one patch - tested in Rockpro64 and Rock-PI-4 - order them in proper way - rebase on master Changes for v2: - handle LPDDR4 code as part of CONFIG_RAM_RK3399_LPDDR4 - support data_training and set_rate via sdram_rk3399_ops - add proper sys_reg_enc macros - add new patch to rename variable sdram_params with params - fix few commit messages. patch 0001 - 0018: add dram config enc macro patch 0019: configure phy IO in ds odt patch 0020: add LPDDR4 config patch 0021 - 0043: lpddr4 data training changes patch 0044 - 0046: syscon pmu support patch 0047: set 50MHz ddr clock patch 0048: set 400MHz ddr clock patch 0049: LPDDR4-400 timings patch 0050: LPDDR4-800 timings patch 0051 - 0052: lpddr4 set rate patch 0053: enable lpddr4 support on Rockpro64 patch 0054: enable lpddr4 support on Rock-PI 4 patch 0055: add LPDDR-100 timings via dts patch 0056: use LPDDR-100 timings on Rockpro64 patch 0057: use LPDDR-100 timings on Rock-PI 4 [1] https://patchwork.ozlabs.org/cover/1116734/ Any inputs?
