Patch "iio: chemical: ccs811: Corrected firmware boot/application mode transition" has been added to the 4.14-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled iio: chemical: ccs811: Corrected firmware boot/application mode transition to the 4.14-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: iio-chemical-ccs811-corrected-firmware-boot-application-mode-transition.patch and it can be found in the queue-4.14 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From b91e146c38b003c899710ede6d05fc824675e386 Mon Sep 17 00:00:00 2001 From: Richard Lai <richard(a)richardman.com> Date: Sat, 17 Feb 2018 16:28:24 +0000 Subject: iio: chemical: ccs811: Corrected firmware boot/application mode transition From: Richard Lai <richard(a)richardman.com> commit b91e146c38b003c899710ede6d05fc824675e386 upstream. CCS811 has different I2C register maps in boot and application mode. When CCS811 is in boot mode, register APP_START (0xF4) is used to transit the firmware state from boot to application mode. However, APP_START is not a valid register location when CCS811 is in application mode (refer to "CCS811 Bootloader Register Map" and "CCS811 Application Register Map" in CCS811 datasheet). The driver should not attempt to perform a write to APP_START while CCS811 is in application mode, as this is not a valid or documented register location. When prob function is being called, the driver assumes the CCS811 sensor is in boot mode, and attempts to perform a write to APP_START. Although CCS811 powers-up in boot mode, it may have already been transited to application mode by previous instances, e.g. unload and reload device driver by the system, or explicitly by user. Depending on the system design, CCS811 sensor may be permanently connected to system power source rather than power controlled by GPIO, hence it is possible that the sensor is never power reset, thus the firmware could be in either boot or application mode at any given time when driver prob function is being called. This patch checks the STATUS register before attempting to send a write to APP_START. Only if the firmware is not in application mode and has valid firmware application loaded, then it will continue to start transiting the firmware boot to application mode.

Patch "clk: sunxi-ng: a31: Fix CLK_OUT_* clock ops" has been added to the 4.14-stable tree

When support for the A31/A31s CCU was first added, the clock ops for the CLK_OUT_* clocks was set to the wrong type. The clocks are MP-type, but the ops was set for div (M) clocks. This went unnoticed until now. This was because while they are different clocks, their data structures aligned in a way that ccu_div_ops would access the second ccu_div_internal and ccu_mux_internal structures, which were valid, if not incorrect. Furthermore, the use of these CLK_OUT_* was for feeding a precise 32.768 kHz clock signal to the WiFi chip. This was achievable by using the parent with the same clock rate and no divider. So the incorrect divider setting did not affect this usage. Commit 946797aa3f08 ("clk: sunxi-ng: Support fixed post-dividers on MP style clocks") added a new field to the ccu_mp structure, which broke the aforementioned alignment. Now the system crashes as div_ops tries to look up a nonexistent table.
