memory: tegra30-emc: Make driver modular

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

Add modularization support to the Tegra30 EMC driver, which now can be compiled as a loadable kernel module. Signed-off-by: Dmitry Osipenko Link: https://lore.kernel.org/r/20201111011456.7875-8-digetx@gmail.com Signed-off-by: Krzysztof Kozlowski

memory: tegra-mc: Add interconnect framework

2020-11-26T17:50:35+00:00

Add common SoC-agnostic ICC framework which turns Tegra Memory Controller into a memory interconnection provider. This allows us to use interconnect API for tuning of memory configurations.

memory: tegra: Remove superfluous error messages around platform_get_irq()

2020-11-26T17:50:35+00:00

The platform_get_irq() prints error message telling that interrupt is missing, hence there is no need to duplicated that message in the drivers. Signed-off-by: Dmitry Osipenko Link: https://lore.kernel.org/r/20201104164923.21238-31-digetx@gmail.com Signed-off-by: Krzysztof Kozlowski

memory: tegra: Add and use devm_tegra_memory_controller_get()

2020-11-26T17:50:29+00:00

Multiple Tegra drivers need to retrieve Memory Controller and there is duplication of the retrieval code among the drivers. Add new devm_tegra_memory_controller_get() helper to remove the code's duplication and to fix put_device() which was missed in the duplicated code. Make EMC drivers to use the new helper.

memory: tegra: Consolidate registers definition into common header

2019-11-11T13:55:27+00:00

The Memory Controller registers definition is sparse and duplicated, let's consolidate everything into a common place for consistency. Acked-by: Peter De Schrijver Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

memory: tegra: Ensure timing control debug features are disabled

2019-11-11T13:55:27+00:00

Timing control debug features should be disabled at a boot time, but you never now and hence it's better to disable them explicitly because some of those features are crucial for the driver to do a proper thing.

memory: tegra: Introduce Tegra30 EMC driver

2019-11-11T13:55:27+00:00

Introduce driver for the External Memory Controller (EMC) found on Tegra30 chips, it controls the external DRAM on the board. The purpose of this driver is to program memory timing for external memory on the EMC clock rate change.

memory: tegra: Set DMA mask based on supported address bits

2019-11-11T13:55:24+00:00

The memory controller on Tegra124 and later supports 34 or more address bits. Advertise that by setting the DMA mask based on the number of the address bits. Signed-off-by: Thierry Reding

memory: tegra: Replace readl-writel with mc_readl-mc_writel

2019-04-18T09:36:10+00:00

There is no need for a memory barriers on reading/writing of register values as we only care about the read/write order, hence let's use the common helpers. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding
