ARM: dts: stm32mp1: DDR config v1.44
Update DDR configuration with the latest update: - PUBL_regs: DXnGCR[0]= according to ddr_width to disable Byte lane 2/3 in 16bit - fix LPDDR2/3 timing_calc to step RL/WL in relaxed timings mode - remove LPDDR3 RL3 (optional) support vs MR0[7] because MR0[7] can't be read instead always apply worse RL/WL for LPDDR3 when freq < 166MHz) - change MR3 to 48ohm drive for LPDDR2/3 - change default ZPROG[7:4] = 0x1 for LPDDR2/3 , '0' is not allowed even when ODT not used - use DQSTRN for LPDDR2/3 (it was not set in PIR) - LPDDR3: set dqsge/dwsgx gate extension to 2,2 like LPDDR2 -DDRCTRL.dfitmg0: + for LPDDR3 tphy_wrlat = WL (as LPDDR2) + improvement for relaxed mode vs RL/Wl at corner case. For example @533MHz RL/WL (relaxed) = 9/5 for LPDDR2/3 and correction to MR2 accordingly - DDR_PCFGQOS1_1: port1 timeout relaxed from 0x00 to 0x40, for LTDC. - DDR_PCFGWQOS0_0: change vpr level from 11 to 12 in order to include the CPU on the variable priority queue. - DDR_SCHED: fix to consider 13 levels (13 levels - 1 = 0xC) Signed-off-by: Patrick Delaunay <patrick.delaunay@st.com>
