From: iuncuim <[email protected]> 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: https://lore.kernel.org/all/[email protected]/
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 https://lore.kernel.org/u-boot/[email protected]/ 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 https://lore.kernel.org/u-boot/[email protected]/ Signed-off-by: Mikhail Kalashnikov <[email protected]> iuncuim (1): sunxi: H616: add LPDDR4 DRAM support .../include/asm/arch-sunxi/dram_sun50i_h616.h | 2 + arch/arm/mach-sunxi/Kconfig | 17 ++ arch/arm/mach-sunxi/dram_sun50i_h616.c | 197 ++++++++++++++---- arch/arm/mach-sunxi/dram_timings/Makefile | 1 + .../dram_timings/h616_lpddr4_2133.c | 95 +++++++++ 5 files changed, 277 insertions(+), 35 deletions(-) create mode 100644 arch/arm/mach-sunxi/dram_timings/h616_lpddr4_2133.c -- 2.42.0
