reset: reset-zynqmp: Fixed the argument data type

2021-09-12T06:56:39+00:00

[ Upstream commit ed104ca4bd9c405b41e968ad4ece51f6462e90b6 ] This patch changes the data type of the variable 'val' from int to u32. Addresses-Coverity: argument of type "int *" is incompatible with parameter of type "u32 *" Signed-off-by: Sai Krishna Potthuri Signed-off-by: Michal Simek Link: https://lore.kernel.org/r/925cebbe4eb73c7d0a536da204748d33c7100d8c.1624448778.git.michal.simek@xilinx.com Signed-off-by: Philipp Zabel Signed-off-by: Sasha Levin

reset: ti-syscon: fix to_ti_syscon_reset_data macro

2021-07-25T12:35:10+00:00

[ Upstream commit 05cf8fffcdeb47aef1203c08cbec5224fd3a0e1c ] The to_ti_syscon_reset_data macro currently only works if the parameter passed into it is called 'rcdev'. Fixes a checkpatch --strict issue: CHECK: Macro argument reuse 'rcdev' - possible side-effects? #53: FILE: drivers/reset/reset-ti-syscon.c:53: +#define to_ti_syscon_reset_data(rcdev) \ + container_of(rcdev, struct ti_syscon_reset_data, rcdev) Signed-off-by: Philipp Zabel Signed-off-by: Sasha Levin

reset: bail if try_module_get() fails

[ Upstream commit 4fb26fb83f0def3d39c14e268bcd4003aae8fade ] Abort instead of returning a new reset control for a reset controller device that is going to have its module unloaded.

reset: brcmstb: Add missing MODULE_DEVICE_TABLE

2021-07-20T14:10:51+00:00

[ Upstream commit e207457f9045343a24d936fbb67eb4b412f1c6ad ] This patch adds missing MODULE_DEVICE_TABLE definition which generates correct modalias for automatic loading of this driver when it is built as an external module.

reset: a10sr: add missing of_match_table reference

2021-07-20T14:10:51+00:00

[ Upstream commit 466ba3c8ff4fae39e455ff8d080b3d5503302765 ] The driver defined of_device_id table but did not use it with of_match_table. This prevents usual matching via devicetree and causes a W=1 warning: drivers/reset/reset-a10sr.c:111:34: warning: ‘a10sr_reset_of_match’ defined but not used [-Wunused-const-variable=] Reported-by: kernel test robot Fixes: 627006820268 ("reset: Add Altera Arria10 SR Reset Controller") Signed-off-by: Krzysztof Kozlowski Link: https://lore.kernel.org/r/20210507112803.20012-1-krzysztof.kozlowski@canonical.com Signed-off-by: Philipp Zabel Signed-off-by: Sasha Levin

reset: uniphier: Add SCSSI reset control for each channel

2020-02-24T07:36:41+00:00

[ Upstream commit f4aec227e985e31d2fdc5608daf48e3de19157b7 ] SCSSI has reset controls for each channel in the SoCs newer than Pro4, so this adds missing reset controls for channel 1, 2 and 3. And more, this moves MCSSI reset ID after SCSSI.

reset: Fix {of,devm}_reset_control_array_get kerneldoc return types

2020-01-23T07:22:43+00:00

commit 723c0011c7f6992f57e2c629fa9c89141acc115f upstream. of_reset_control_array_get() and devm_reset_control_array_get() return struct reset_control pointers, not internal struct reset_control_array pointers, just like all other reset control API calls. Correct the kerneldoc to match the code.

reset: brcmstb: Remove resource checks

2020-01-17T18:48:29+00:00

commit ce89d8d3a70fa530e16f0b0f8994385a214cd0c0 upstream. The use of IS_ALIGNED() is incorrect, the typical resource we pass looks like this: start: 0x8404318, size: 0x30. When using IS_ALIGNED() we will get the following 0x8404318 & (0x18 - 1) = 0x10 which is definitively not equal to 0, same goes with the size. These two checks would make the driver fail probing. Remove the resource checks, since there should be no constraint on the base addresse or size.

reset: Do not register resource data for missing resets

2020-01-12T11:21:21+00:00

[ Upstream commit db23808615e29d9a04f96806cac56f78b0fee0ef ] When an optional reset is not present, __devm_reset_control_get() and devm_reset_control_array_get() still register resource data to release the non-existing reset on cleanup, which is futile. Fix this by skipping NULL reset control pointers. Signed-off-by: Geert Uytterhoeven Signed-off-by: Philipp Zabel Signed-off-by: Sasha Levin
