Hello, There are couple things could be improved in tegra-apbmisc.c and this patchset addresses them. Please note that the fallback for older device trees was broken for T124 since 2015, so it is also a minor change. Changelog: v4: - Rebased on recent linux-next which got this change 1188dd7d3fbd. v3: - Michał Mirosław suggested to unmap APB MISC registers after they are not needed anymore. There is now a new patch which does that, see patch "Unmap registers once they are not needed anymore". v2: - Corrected commit's title of the "Warn if straps are not ready" patch. Dmitry Osipenko (4): soc/tegra: fuse: Cache values of straps and Chip ID registers soc/tegra: fuse: Warn if straps are not ready soc/tegra: fuse: Correct straps' address for older Tegra124 device trees soc/tegra: fuse: Unmap registers once they are not needed anymore drivers/soc/tegra/fuse/tegra-apbmisc.c | 33 +++++++++++++++----------- 1 file changed, 19 insertions(+), 14 deletions(-) -- 2.24.0
