I'm going to run this through our internal test system to make sure there aren't any regressions. I can carry these in the Tegra tree for a little bit until we're reasonable sure that these patches are all safe to apply and then send a pull request sometime next week. I've also included a patch as suggested by Dmitry to keep I2C interrupts enabled during suspend/resume and I'm currently checking if that may be a fix for a suspend/resume issue that I've seen on Jetson Nano where we don't have working suspend/resume yet. Thierry Dmitry Osipenko (2): i2c: tegra: Better handle case where CPU0 is busy for a long time i2c: tegra: Synchronize DMA before termination Thierry Reding (3): Revert "i2c: tegra: Fix suspending in active runtime PM state" i2c: tegra: Restore pinmux on system resume i2c: tegra: Keep IRQs enabled during suspend/resume drivers/i2c/busses/i2c-tegra.c | 61 +++++++++++++++++++--------------- 1 file changed, 35 insertions(+), 26 deletions(-) -- 2.24.1
