Subject: [PATCH 5/8] clk: qcom: ipq8074: Fix gcc_snoc_bus_timeout_ahb_clk
offset
By default, the ipq8074 V2 clks are provided in the gcc driver.
Updating the gcc_snoc_bus_timeout_ahb_clk offsets also as needed
in ipq8074 V2.

From 52315bec6ed633b6a71f28b746029602f8bd70b9 Mon Sep 17 00:00:00 2001

Date: Wed, 22 Apr 2020 20:35:30 +0530
Subject: [PATCH] clk: ipq8074: fix gcc_blsp1_ahb_clk properties
All the voting enabled clocks does not support the enable
from CBCR register. So, updated gcc_blsp1_ahb_clk enable
register and mask to enable bit in APCS_CLOCK_BRANCH_ENA_VOTE.
Also, the voting controlled clocks are shared among multiple
components like APSS, RPM, NSS, TZ, etc. So, turning the
voting off from APSS does not make the clock off if it has
been voted from another component. Added the flag
BRANCH_HALT_VOTED in order to skip checking the clock
disable status.
This change is referred from the below commits,

Subject: [PATCH 246/281] net:ipv6: Fix IPv6 user route change event calls
These events should be called only when the route table is
changed by the userspace. So, we should call them in the
ioctl and the netlink message handler function.
Change-Id: If7ec615014cfc79d5fa72878e49eaf99c2560c32

It looks like commit 0857d6f8c759 ("ipv6: When forwarding count rx stats
on the orig netdev") tries to determine the right netdev to account the
rx stats, but in this particular case it's failing and the netdev is
NULL.
Fallback to the previous method of determining the netdev interface (via
skb->dev) to account the rx stats when the orig netdev can't be
determined.
Fixes: 0857d6f8c759 ("ipv6: When forwarding count rx stats on the orig netdev")

Subject: [PATCH 5/8] clk: qcom: ipq8074: Fix gcc_snoc_bus_timeout_ahb_clk
offset
By default, the ipq8074 V2 clks are provided in the gcc driver.
Updating the gcc_snoc_bus_timeout_ahb_clk offsets also as needed
in ipq8074 V2.

Date: Wed, 22 Apr 2020 20:35:30 +0530
Subject: [PATCH] clk: ipq8074: fix gcc_blsp1_ahb_clk properties
All the voting enabled clocks does not support the enable
from CBCR register. So, updated gcc_blsp1_ahb_clk enable
register and mask to enable bit in APCS_CLOCK_BRANCH_ENA_VOTE.
Also, the voting controlled clocks are shared among multiple
components like APSS, RPM, NSS, TZ, etc. So, turning the
voting off from APSS does not make the clock off if it has
been voted from another component. Added the flag
BRANCH_HALT_VOTED in order to skip checking the clock
disable status.
This change is referred from the below commits,
1. 246b4fb3af9bd65d8af794aac2f0e7b1ed9cc2dd

Subject: [PATCH 246/281] net:ipv6: Fix IPv6 user route change event calls
These events should be called only when the route table is
changed by the userspace. So, we should call them in the
ioctl and the netlink message handler function.
Change-Id: If7ec615014cfc79d5fa72878e49eaf99c2560c32

It looks like commit 0857d6f8c759 ("ipv6: When forwarding count rx stats
on the orig netdev") tries to determine the right netdev to account the
rx stats, but in this particular case it's failing and the netdev is
NULL.
Fallback to the previous method of determining the netdev interface (via
skb->dev) to account the rx stats when the orig netdev can't be
determined.
Fixes: 0857d6f8c759 ("ipv6: When forwarding count rx stats on the orig netdev")
