memory: tegra30-emc: Print additional memory info

2022-01-27T09:40:34+00:00

Print out memory type and LPDDR2 configuration on Tegra30, making it similar to the memory info printed by the Tegra20 memory driver. This info is useful for debugging purposes.

memory: tegra20-emc: Support matching timings by LPDDR2 configuration

2021-10-15T07:52:47+00:00

ASUS Transformer TF101 doesn't provide RAM code and in this case memory timings should be selected based on identity information read out from SDRAM chip. Support matching timings by LPDDR2 configuration. Signed-off-by: Dmitry Osipenko Link: https://lore.kernel.org/r/20211006224659.21434-10-digetx@gmail.com Signed-off-by: Krzysztof Kozlowski

memory: tegra124: Support interconnect framework

2021-01-05T17:03:22+00:00

Now Internal and External memory controllers are memory interconnection providers. This allows us to use interconnect API for tuning of memory configuration. EMC driver now supports OPPs and DVFS.

memory: tegra124-emc: Make driver modular

2021-01-05T17:00:09+00:00

Add modularization support to the Tegra124 EMC driver, which now can be compiled as a loadable kernel module. Note that EMC clock must be registered at clk-init time, otherwise PLLM will be disabled as unused clock at boot time if EMC driver is compiled as a module. Hence add a prepare/complete callbacks. similarly to what is done for the Tegra20/30 EMC drivers.

memory: tegra30: Support interconnect framework

2020-12-05T13:54:36+00:00

Now Internal and External memory controllers are memory interconnection providers. This allows us to use interconnect API for tuning of memory configuration. EMC driver now supports OPPs and DVFS. MC driver now supports tuning of memory arbitration latency, which needs to be done for ISO memory clients, like a Display client for example.

memory: tegra20-emc: Add devfreq support

2020-11-26T17:50:36+00:00

Add devfreq support to the Tegra20 EMC driver. Memory utilization statistics will be periodically polled from the memory controller and appropriate minimum clock rate will be selected by the devfreq governor.
