soc/tegra: cbb: Changes for v6.1-rc1 This introduces the CBB driver that is used to provide (a lot of) information about SErrors when things go wrong, instead of the kernel just crashing or hanging. * tag 'tegra-for-6.1-cbb' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux: soc/tegra: cbb: Add support for Tegra241 (Grace) soc/tegra: cbb: Add driver for Tegra234 CBB 2.0 soc/tegra: cbb: Add CBB 1.0 driver for Tegra194 soc/tegra: Set ERD bit to mask inband errors Link: https://lore.kernel.org/r/20220916101957.1635854-2-thierry.reding@gmail.com Signed-off-by: Arnd Bergmann

soc/tegra: fuse: Add missing of_node_put()

2022-09-15T10:38:43Z

In tegra_init_apbmisc(), of_find_matching_node() will return a node pointer with refcount incremented. We should use of_node_put() in each failure path or when it is not used anymore. Signed-off-by: Liang He Signed-off-by: Thierry Reding

soc/tegra: fuse: Add missing of_node_put() in tegra_init_fuse()

In this function, of_find_matching_node() will return a node pointer with refcount incremented. We should use of_node_put() when the "np" pointer is not used anymore. Signed-off-by: Liang He Signed-off-by: Thierry Reding

soc/tegra: Set ERD bit to mask inband errors

2022-09-15T10:30:11Z

Add a function to set the ERD (Error Response Disable) bit in the MISCREG_CCROC_ERR_CONFIG register from the Control Backbone (CBB) error handler driver. ERD bit allows masking of SError due to inband errors which are caused by illegal register accesses through CBB. When the bit is set, interrupt is used for reporting errors and magic code '0xdead2003' is returned. This change is only required for Tegra194 SoC as the config is moved to CBB register space for future SoC's. Also, remove unmapping the apbmisc_base as it's required to get the base address for accessing the misc register. Signed-off-by: Sumit Gupta Signed-off-by: Thierry Reding

soc/tegra: fuse: Add nvmem cell lookup entries for Tegra194

2022-04-06T12:55:50Z

soc/tegra: fuse: Explicitly cast to/from __iomem

2022-02-24T16:09:13Z

sparse is picky about casts between different address spaces. A cast to plain void * needs to be accompanied by a __force modifier and casting back to void __iomem * needs to be explicit to avoid warnings.
