We just changed the code so we apply bias disable on the correct register but forgot to align the register calculation. The result is that we apply the change on the correct register, but possibly at the incorrect offset/bit
This went undetected because offsets tends to be the same between REG_PULL and REG_PULLEN for a given pin the EE controller. This is not true for the AO controller.

Commit 6975a783d7b4 ("powerpc/boot: Allow building the zImage wrapper as a relocatable ET_DYN", 2011-04-12) changed the procedure descriptor at the start of crt0.S to have a hard-coded start address of 0x500000 rather than a reference to _zimage_start, presumably because having a reference to a symbol introduced a relocation which is awkward to handle in a position-independent executable. Unfortunately, what is at 0x500000 in the COFF image is not the first instruction, but the procedure descriptor itself, that is, a word containing 0x500000, which is not a valid instruction. Hence, booting a COFF zImage results in a "DEFAULT CATCH!, code=FFF00700" message from Open Firmware.
This fixes the problem by (a) putting the procedure descriptor in the data section and (b) adding a branch to _zimage_start as the first instruction in the program.

The sw2iso count should cover ARM LDO ramp-up time, the MAX ARM LDO ramp-up time may be up to more than 100us on some boards, this patch sets sw2iso to 0xf (~384us) which is the reset value, and it is much more safe to cover different boards, since we have observed that some customer boards failed with current setting of 0x2.

There is actually a space after "sp," like this,
ffff2000080813c8: a9bb7bfd stp x29, x30, [sp, #-80]!
Right now, checkstack.pl isn't able to print anything on aarch64, because it won't be able to match the stating objdump line of a function due to this missing space. Hence, it displays every stack as zero-size.
After this patch, checkpatch.pl is able to match the start of a function's objdump, and is then able to calculate each function's stack correctly.

With PM enabled, I noticed that pressing a key on the droid4 keyboard will block deeper idle states for the SoC. Let's fix this by using IRQF_ONESHOT and stop constantly toggling the device OMAP4_KBD_IRQENABLE register as suggested by Dmitry Torokhov dmitry.torokhov@gmail.com.
From the hardware point of view, looks like we need to manage the registers
for OMAP4_KBD_IRQENABLE and OMAP4_KBD_WAKEUPENABLE together to avoid blocking deeper SoC idle states. And with toggling of OMAP4_KBD_IRQENABLE register now gone with IRQF_ONESHOT, also the SoC idle state problem is gone during runtime. We still also need to clear OMAP4_KBD_WAKEUPENABLE in omap4_keypad_close() though to pair it with omap4_keypad_open() to prevent blocking deeper SoC idle states after rmmod omap4-keypad.

Driver sends update-SVID ramrod in the MFW notification path. If there is a pending ramrod, driver doesn't retry the command and storm firmware will never be updated with the SVID value. The patch adds changes to send update-svid ramrod in process context with retry/poll flags set.

There are two test cases: 1. Remove the 4 modules:hns_enet_drv/hns_dsaf/hnae/hns_mdio, and install them again, must use "ifconfig down/ifconfig up" command pair to bring port to work.
This patch calls phy_stop function when init phy to fix this bug.
2. Remove the 2 modules:hns_enet_drv/hns_dsaf, and install them again, all ports can not use anymore, because of the phy devices register failed(phy devices already exists).
Phy devices are registered when hns_dsaf installed, this patch removes them when hns_dsaf removed.
The two cases are sometimes related, fixing the second case also requires fixing the first case, so fix them together.

There will be a large number of MAC pause frames on the net, which caused tx timeout of net device. And then the net device was reset to try to recover it. So that is not useful, and will cause some other problems.
So need doubled ndev->watchdog_timeo if device watchdog occurred until watchdog_timeo up to 40s and then try resetting to recover it.
When collecting dfx information such as hardware registers when tx timeout. Some registers for count were cleared when read. So need move this task before update net state which also read the count registers.

[ Upstream commit 15515aaaa69659c502003926a2067ee76176148a ]
Current state for the lan78xx driver does not allow for changing the MAC address of the interface, without either removing the module (if you compiled it that way) or rebooting the machine. If you attempt to change the MAC address, ifconfig will show the new address, however, the system/interface will not respond to any traffic using that configuration. A few short-term options to work around this are to unload the module and reload it with the new MAC address, change the interface to "promisc", or reboot with the correct configuration to change the MAC.
This patch enables the ability to change the MAC address via fairly normal means... ifdown <interface> modify entry in /etc/network/interfaces OR a similar method ifup <interface> Then test via any network communication, such as ICMP requests to gateway.
My only test platform for this patch has been a raspberry pi model 3b+.

At least old Xen net backends seem to send frags with no real data sometimes. In case such a fragment happens to occur with the frag limit already reached the frontend will BUG currently even if this situation is easily recoverable.
Modify the BUG_ON() condition accordingly.

Currently variable data0 is not being initialized so a garbage value is being passed to vxge_hw_vpath_fw_api and this value is being written to the rts_access_steer_data0 register. There are other occurrances where data0 is being initialized to zero (e.g. in function vxge_hw_upgrade_read_version) so I think it makes sense to ensure data0 is initialized likewise to 0.

When netxen_rom_fast_read() fails, "bios" is left uninitialized and may contain random value, thus should not be used.
The fix ensures that if netxen_rom_fast_read() fails, we return "-EIO".

[ Upstream commit d430aff8cd0c57502d873909c184e3b5753f8b88 ]
The function of_find_node_by_path() acquires a reference to the node returned by it and that reference needs to be dropped by its caller.
su_get_type() doesn't do that. The match node are used as an identifier to compare against the current node, so we can directly drop the refcount after getting the node from the path as it is not used as pointer.
Fix this by use a single variable and drop the refcount right after of_find_node_by_path().
