10de2114 - memory: tegra: Add EMC scaling support code for Tegra210

Wed, 29 May 2019 08:21:36 +0000

memory: tegra: Add EMC scaling support code for Tegra210This is the initial patch for Tegra210 EMC frequency scaling. It has thecode to program various aspects of the EMC that are standardized, but itdoes not yet include the specific programming sequence needed for clockscaling.The driver is designed to support LPDDR4 SDRAM. Devices that use LPDDR4need to perform training of the RAM before it can be used. Firmware willperform this training during early boot and pass a table of supportedfrequencies to the kernel via device tree.For the frequencies above 800 MHz, periodic retraining is needed tocompensate for changes in timing. This periodic training will have to beperformed until the frequency drops back to or below 800 MHz.This driver provides helpers used during this runtime retraining thatwill be used by the sequence specific code in a follow-up patch.Based on work by Peter De Schrijver .Signed-off-by: Joseph Lo Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/memory/tegra/Kconfig

89184651 - memory: Add NVIDIA Tegra memory controller support

Wed, 16 Apr 2014 07:24:44 +0000

memory: Add NVIDIA Tegra memory controller supportThe memory controller on NVIDIA Tegra exposes various knobs that can beused to tune the behaviour of the clients attached to it.Currently this driver sets up the latency allowance registers to the HWdefaults. Eventually an API should be exported by this driver (via acustom API or a generic subsystem) to allow clients to register latencyrequirements.This driver also registers an IOMMU (SMMU) that's implemented by thememory controller. It is supported on Tegra30, Tegra114 and Tegra124currently. Tegra20 has a GART instead.The Tegra SMMU operates on memory clients and SWGROUPs. A memory clientis a unidirectional, special-purpose DMA master. A SWGROUP represents aset of memory clients that form a logical functional unit correspondingto a single device. Typically a device has two clients: one client forread transactions and one client for write transactions, but there arealso devices that have only read clients, but many of them (such as thedisplay controllers).Because there is no 1:1 relationship between memory clients and devicesthe driver keeps a table of memory clients and the SWGROUPs that theybelong to per SoC. Note that this is an exception and due to the factthat the SMMU is tightly integrated with the rest of the Tegra SoC. Theuse of these tables is discouraged in drivers for generic IOMMU devicessuch as the ARM SMMU because the same IOMMU could be used in any numberof SoCs and keeping such tables for each SoC would not scale.Acked-by: Joerg Roedel Signed-off-by: Thierry Reding List of files: /linux-6.15/drivers/memory/tegra/Kconfig
