memory: tegra: Fix integer overflow on tick value calculation

2019-05-25T16:26:49+00:00

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

2018-08-03T05:55:24+00:00

[ 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

2018-08-03T05:55:24+00:00

[ 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

ARM: OMAP2+: gpmc-onenand: propagate error on initialization failure

[ Upstream commit 7807e086a2d1f69cc1a57958cac04fea79fc2112 ] gpmc_probe_onenand_child returns success even on gpmc_onenand_init failure. Fix that. Signed-off-by: Ladislav Michl Acked-by: Roger Quadros Signed-off-by: Tony Lindgren Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman

memory/atmel-ebi: Fix ns <-> cycles conversions

2017-03-15T02:02:45+00:00

commit ee194289502a6901cc77dc9a893bf2afd351ac5e upstream. at91sam9_ebi_get_config() is incorrectly converting timings in clock cycles into timings in nanoseconds by multiplying the cycle values by the clk rate instead of the clk period. at91sam9_ebi_xslate_config() has the same problem for the tdf_ns -> tdf_cycles conversion.

memory: atmel-sdramc: fix a possible NULL dereference

2016-08-31T17:19:16+00:00

of_match_device could return NULL, and so cause a NULL pointer dereference later. For fixing this problem, we use of_device_get_match_data(), this will simplify the code a little by using a standard function for getting the match data. Signed-off-by: LABBE Corentin Signed-off-by: Alexandre Belloni
