memory: tegra: Consolidate registers definition into common header

2019-11-11T13:55:27Z

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

2019-11-11T13:55:27Z

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

2019-11-11T13:55:27Z

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

2019-11-11T13:55:24Z

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

2019-04-18T09:36:10Z

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

memory: tegra: Fix integer overflow on tick value calculation

2019-04-18T09:35:55Z

Multiplying the Memory Controller clock rate by the tick count results in an integer overflow and in result the truncated tick value is being programmed into hardware, such that the GR3D memory client performance is reduced by two times.

memory: tegra: Fix missed registers values latching

2019-04-18T09:35:38Z

Some of Memory Controller registers are shadowed and require latching in order to copy assembly state into the active, MC_EMEM_ARB_CFG is one of these registers. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding

memory: tegra: Properly spell "tegra"

2019-04-11T15:58:41Z

Rename all occurrences of "terga" to "tegra". It's an easy typo to make and a difficult one to spot. Reviewed-by: Dmitry Osipenko Signed-off-by: Thierry Reding

memory: tegra: Clean up error messages
