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

2019-01-16T12:54:13Z

Make all messages to start with a lower case and don't unnecessarily go over 80 chars in the code. Signed-off-by: Dmitry Osipenko Signed-off-by: Joerg Roedel

memory: tegra: Do not ask for IRQ sharing

2019-01-16T12:54:13Z

Memory Controller driver never shared IRQ with any other driver and very unlikely that it will. Hence there is no need to request IRQ sharing and the corresponding flag can be dropped safely. Signed-off-by: Dmitry Osipenko Signed-off-by: Joerg Roedel

memory: tegra: Do not try to probe SMMU on Tegra20

2019-01-16T12:54:13Z

Tegra20 doesn't have SMMU. Move out checking of the SMMU presence from the SMMU driver into the Memory Controller driver. This change makes code consistent in regards to how GART/SMMU presence checking is performed. Signed-off-by: Dmitry Osipenko Signed-off-by: Joerg Roedel

iommu/tegra: gart: Integrate with Memory Controller driver

2019-01-16T12:54:12Z

The device-tree binding has been changed. There is no separate GART device anymore, it is squashed into the Memory Controller. Integrate GART module with the MC in a way it is done for the SMMU on Tegra30+. Signed-off-by: Dmitry Osipenko Signed-off-by: Joerg Roedel

memory: tegra: Use of_device_get_match_data()

2019-01-16T12:54:12Z

There is no need to match device with the DT node since it was already matched, use of_device_get_match_data() helper to get the match-data. Signed-off-by: Dmitry Osipenko Acked-by: Thierry Reding Signed-off-by: Joerg Roedel
