2022-02-17clk: mediatek: Warn if clk IDs are duplicatedChen-Yu Tsai5-6/+34
The Mediatek clk driver library handles duplicate clock IDs in two different ways: either ignoring the duplicate entry, or overwriting the old clk. Either way may cause unexpected behavior, and the latter also causes an orphan clk that cannot be cleaned up. Align the behavior so that later duplicate entries are ignored, and a warning printed. The warning will also aid in making the issue noticeable.

2022-02-17clk: mediatek: gate: Implement unregister APIChen-Yu Tsai2-0/+38
The gate clk type within the MediaTek clk driver library only has a register function, and no corresponding unregister function. This means there is no way for its users to properly implement cleanup and removal. Add a matching unregister function for the gate type clk.

2022-02-17clk: mediatek: gate: Consolidate gate type clk related codeChen-Yu Tsai4-77/+77
Right now some bits of the gate type clk code are in clk-gate.[ch], but other bits are in clk-mtk.[ch]. This is different from the cpumux and mux type clks, for which all of the code are found in the same files. Move the functions that register multiple clks from a given list, mtk_clk_register_gates_with_dev() and mtk_clk_register_gates(), to clk-gate.[ch] to consolidate all the code for the gate type clks. This commit only moves code with minor whitespace fixups to correct the code style. Further improvements, such as internalizing various functions and structures will be done in later commits.

2022-02-17bonding: force carrier update when releasing slaveZhang Changzhong1-3/+2
In __bond_release_one(), bond_set_carrier() is only called when bond device has no slave. Therefore, if we remove the up slave from a master with two slaves and keep the down slave, the master will remain up. Fix this by moving bond_set_carrier() out of if (!bond_has_slaves(bond)) statement. Reproducer: $ insmod bonding.ko mode=0 miimon=100 max_bonds=2 $ ifconfig bond0 up $ ifenslave bond0 eth0 eth1 $ ifconfig eth0 down $ ifenslave -d bond0 eth1 $ cat /proc/net/bonding/bond0 Fixes: ff59c4563a8d ("[PATCH] bonding: support carrier state for master") Signed-off-by: Zhang Changzhong <zhangchangzhong@huawei.com> Acked-by: Jay Vosburgh <jay.vosburgh@canonical.com> Link: https://lore.kernel.org/r/1645021088-38370-1-git-send-email-zhangchangzhong@huawei.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
