[PATCH OLK-6.6 210/602] platform/chrome: cros_ec_lpc: Separate host command and irq disable
by pkwarcraft＠hotmail.com 05 Dec '23

05 Dec '23

From: Lalith Rajendran <lalithkraj(a)chromium.org> stable inclusion from stable-v6.6.2 commit 5eafd56d0992eeebd3df3a8f25a2583e6ddad0dc category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit 47ea0ddb1f5604ba3496baa19110aec6a3151f2e ] Both cros host command and irq disable were moved to suspend prepare stage from late suspend recently. This is causing EC to report MKBP event timeouts during suspend stress testing. When the MKBP event timeouts happen during suspend, subsequent wakeup of AP by EC using MKBP doesn't happen properly. Move the irq disabling part back to late suspend stage which is a general suggestion from the suspend kernel documentaiton to do irq disable as late as possible.

From: Guenter Roeck <linux(a)roeck-us.net> stable inclusion from stable-v6.6.2 commit a32a93ec7e3dcb7c6fea0c68ded5dadd8b783c12 category: bugfix bugzilla: https://gitee.com/openeuler/kernel/issues/I8IW7G Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id… -------------------------------- [ Upstream commit d621a46d05107f4e510383d6a38f2160c62d28f7 ] This reverts commit 393935baa45e5ccb9603cf7f9f020ed1bc0915f7. As reported by Ian Nartowicz, this and the next patch result in a failure to load the driver on Celsius W280. While the alternative would be to add the board to the DMI override table, it is quite likely that other systems are also affected. Revert the offending patches to avoid future problems.
