ARM: tegra: Fix Tegra30 Cardhu PCA954x reset 2018-12-16T22:08:13+00:00 Jon Hunter jonathanh@nvidia.com 2018-07-03T08:59:47+00:00 0e3db9f650a6f6fdba17e6da378d0cbacb40d20b commit 6e1811900b6fe6f2b4665dba6bd6ed32c6b98575 upstream. On all versions of Tegra30 Cardhu, the reset signal to the NXP PCA9546 I2C mux is connected to the Tegra GPIO BB0. Currently, this pin on the Tegra is not configured as a GPIO but as a special-function IO (SFIO) that is multiplexing the pin to an I2S controller. On exiting system suspend, I2C commands sent to the PCA9546 are failing because there is no ACK. Although it is not possible to see exactly what is happening to the reset during suspend, by ensuring it is configured as a GPIO and driven high, to de-assert the reset, the failures are no longer seen. Please note that this GPIO is also used to drive the reset signal going to the camera connector on the board. However, given that there is no camera support currently for Cardhu, this should not have any impact.

zboot: fix stack protector in compressed boot phase 2018-10-21T07:45:16+00:00 Huacai Chen chenhc@lemote.com 2018-04-05T23:18:18+00:00 4b998a0ba5085f532bdc9d57e5c2ac8910176cf6 commit 7bbaf27d9c83037b6e60a818e57bdbedf6bc15be upstream. Calling __stack_chk_guard_setup() in decompress_kernel() is too late that stack checking always fails for decompress_kernel() itself. So remove __stack_chk_guard_setup() and initialize __stack_chk_guard before we call decompress_kernel(). Original code comes from ARM but also used for MIPS and SH, so fix them together. If without this fix, compressed booting of these archs will fail because stack checking is enabled by default (>=4.16).
