memory: emif: Remove bogus debugfs error handling

2020-11-10T09:22:15Z

[ Upstream commit fd22781648080cc400772b3c68aa6b059d2d5420 ] Callers are generally not supposed to check the return values from debugfs functions. Debugfs functions never return NULL so this error handling will never trigger. (Historically debugfs functions used to return a mix of NULL and error pointers but it was eventually deemed too complicated for something which wasn't intended to be used in normal situations). Delete all the error handling.

memory: fsl-corenet-cf: Fix handling of platform_get_irq() error

[ Upstream commit dd85345abca60a8916617e8d75c0f9ce334336dd ] platform_get_irq() returns -ERRNO on error. In such case comparison to 0 would pass the check.

memory/tegra: Add number of TLB lines for Tegra124

2020-05-10T08:26:14Z

commit e2127ae7a5e80eb53ad431c39145767391da40cd upstream. Tegra124 was accidentally left out when the number of TLB lines was parameterized in commit 11cec15bf3fb ("iommu/tegra-smmu: Parameterize number of TLB lines"). Fortunately this doesn't cause any noticeable regressions upstream, presumably because there aren't any use-cases that exercise enough pressure on the SMMU. But it is a regression nonetheless, so let's fix it.

memory: tegra: Fix integer overflow on tick value calculation

2019-06-11T10:23:46Z

commit b906c056b6023c390f18347169071193fda57dde upstream. 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: Apply interrupts mask per SoC

2018-08-06T14:24:38Z

[ Upstream commit 1c74d5c0de0c2cc29fef97a19251da2ad6f579bd ] Currently we are enabling handling of interrupts specific to Tegra124+ which happen to overlap with previous generations. Let's specify interrupts mask per SoC generation for consistency and in a preparation of squashing of Tegra20 driver into the common one that will enable handling of GART faults which may be undesirable by newer generations.

memory: tegra: Do not handle spurious interrupts

2018-08-06T14:24:38Z

[ Upstream commit bf3fbdfbec947cdd04b2f2c4bce11534c8786eee ] The ISR reads interrupts-enable mask, but doesn't utilize it. Apply the mask to the interrupt status and don't handle interrupts that MC driver haven't asked for. Kernel would disable spurious MC IRQ and report the error. This would happen only in a case of a very severe bug. Signed-off-by: Dmitry Osipenko Signed-off-by: Thierry Reding Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

memory: omap-gpmc: Fix omap gpmc EXTRADELAY timing

2016-07-27T16:47:35Z

commit 8f50b8e57442d28e41bb736c173d8a2490549a82 upstream. In the omap gpmc driver it can be noticed that GPMC_CONFIG4_OEEXTRADELAY is overwritten by the WEEXTRADELAY value from the device tree and GPMC_CONFIG4_WEEXTRADELAY is not updated by the value from the device tree. As a consequence, the memory accesses cannot be configured properly when the extra delay are needed for OE and WE. Fix the update of GPMC_CONFIG4_WEEXTRADELAY with the value from the device tree file and prevents GPMC_CONFIG4_OEXTRADELAY being overwritten by the WEXTRADELAY value from the device tree.
