MediaTek bus fabric provides TrustZone security support and data protection to prevent slaves from being accessed by unexpected masters. The security violation is logged and sent to the processor for further analysis or countermeasures. Any occurrence of security violation would raise an interrupt, and it will be handled by mtk-devapc driver. The violation information is printed in order to find the murderer. Signed-off-by:

There is no reason to keep on using the __raw_{read,write}l() I/O accessors in Renesas ARM driver code. Switch to using the plain {read,write}l() I/O accessors, to have a chance that this works on big-endian. Suggested-by:Arnd Bergmann <arnd@kernel.org> Signed-off-by:

According to Tegra X1 TRM, there are missing swgroups in the tegra210_swgroups list. So this patch adds them to the list. Note that the TEGRA_SWGROUP_GPU (in list) should be actually TEGRA_SWGROUP_GPUB (in TRM), yet TEGRA_SWGROUP_GPU (in TRM) is not being used -- only TEGRA_SWGROUP_GPUB (in TRM) is. So this patch does not add TEGRA_SWGROUP_GPU (in TRM) and keeps TEGRA_SWGROUP_GPU (in list) as it is. Signed-off-by:
