+##  Details taken from the eLinux wiki
+##  For up-to-date information please refer to wiki page.
+##
+##  Wiki Location : http://elinux.org/RPi_config.txt
+##
+##
+##  Description:
+##    Details of each setting are described with each section that begins with
+##    a double hashed comment ('##')
+##    It is up to the user to remove the single hashed comment ('#') from each
+##    option they want to enable, and to set the specific value of that option.
+##
+##  WARNING: Setting the following combination of parameters will set a
+##  permanent bit within the SOC and your warranty is void.
+##    over_voltage>0, and at least one of the following:
+##      force_turbo=1
+##      current_limit_override=0x5A000020
+##      temp_limit>85
+##
+##  Overclock settings will be disabled at runtime if the SoC reaches temp_limit

+##  WARNING: Setting the following combination of parameters will set a
+##  permanent bit within the SOC and your warranty is void.

+Subject: [PATCH 679/692] w1: ds2805: rename w1_family struct, fixing c-p typo
+
+commit 0e3743d870711ae4daf1e7170c8d9381564e244d upstream.
+
+The ds2805 has a structure named: w1_family_2d, which surely
+comes from a w1_ds2431 module. This commit fixes this name to
+prevent confusion and mark a correct family name.

+
+commit c50d09a86172073f55ebac0b92ad5a75907d64e7 upstream.
+
+The state_read() was calling PIO_ACCESS_READ once and bail out if it
+failed for this first time.
+This commit is improving this to trying more times before it give up,
+similarly as the write call is currently doing.

+Subject: [PATCH 682/692] w1: ds2413: when the slave is not responding during
+ read, select it again
+
+commit 3856032a0628e6b94badb9131a706dda185e071d upstream.
+
+The protocol is not allowing to obtain a byte of 0xff for PIO_ACCESS_READ
+call. It is very likely that the slave was not addressed properly and
+it is just not respoding (leaving the bus in logic high state) during
+the read of sampled PIO value.
+We cannot just call w1_reset_resume_command() because the problem will
+persist, instead try selecting (addressing) the slave again.

+Subject: [PATCH 689/692] arm: dts: Add coherent_pool=1M to Pi 4 bootargs
+
+Downstream Raspberry Pi dts files add "coherent_pool=1M" to the kernel
+command line to aid the dwc_otg driver, but this excluded Pi 4 which
+uses a new XCHI interface instead. UAS also benefits from a larger
+coherent_pool value, so replicate the addition in bcm2711-rpi-4-b.dts.
