2023-01-20parport_pc: Let chipset drivers mask unsupported modesMaciej W. Rozycki
Rename `parport_pc_probe_port' to `__parport_pc_probe_port' and add a `mode_mask' parameter so that callers can specify a mask of unsupported modes to exclude even if mode probing seems to indicate otherwise. Add a `parport_pc_probe_port' wrapper with an implicit mask of 0 for the current callers to use. No functional change at this point, but the configuration of data write handlers is now no longer intertwined with determination and reporting of available modes. Signed-off-by: Maciej W.

2023-01-20drivers: bus: simple-pm-bus: Use clocksLiu Ying
Simple Power-Managed bus controller may need functional clock(s) to be enabled before child devices connected to the bus can be accessed. Get the clock(s) as a bulk and enable/disable the clock(s) when the bus is being power managed. One example is that Freescale i.MX8qxp pixel link MSI bus controller needs MSI clock and AHB clock to be enabled before accessing child devices.

2023-01-20scripts/tags.sh: choose which directories to exclude from being indexedPaulo Miguel Almeida
It's common for drivers that share same physical components to also duplicate source code (or at least portions of it). A good example is both drivers/gpu/drm/amdgpu/* and drivers/gpu/drm/radeon/* have a header file called atombios.h. While their contents aren't the same, a lot of their structs have the exact same names which makes navigating through the code base a bit messy as cscope will show up 'references' across drivers which aren't exactly correct. Add IGNORE_DIRS variable, which specifies which directories to be ignored from indexing.

2023-01-20net: stmmac: enable all safety features by defaultAndrew Halaney
In the original implementation of dwmac5 commit 8bf993a5877e ("net: stmmac: Add support for DWMAC5 and implement Safety Features") all safety features were enabled by default. Later it seems some implementations didn't have support for all the features, so in commit 5ac712dcdfef ("net: stmmac: enable platform specific safety features") the safety_feat_cfg structure was added to the callback and defined for some platforms to selectively enable these safety features. The problem is that only certain platforms were given that software support. If the automotive safety package bit is set in the hardware features register the safety feature callback is called for the platform, and for platforms that didn't get a safety_feat_cfg defined this results in the following NULL pointer dereference: [ 7.933303] Call trace: [ 7.935812] dwmac5_safety_feat_config+0x20/0x170 [stmmac] [ 7.941455] __stmmac_open+0x16c/0x474 [stmmac] [ 7.946117] stmmac_open+0x38/0x70 [stmmac] [ 7.950414] __dev_open+0x100/0x1dc [ 7.954006] __dev_change_flags+0x18c/0x204 [ 7.958297] dev_change_flags+0x24/0x6c [ 7.962237] do_setlink+0x2b8/0xfa4 [ 7.965827] __rtnl_newlink+0x4ec/0x840 [ 7.969766] rtnl_newlink+0x50/0x80 [ 7.973353] rtnetlink_rcv_msg+0x12c/0x374 [ 7.977557] netlink_rcv_skb+0x5c/0x130 [ 7.981500] rtnetlink_rcv+0x18/0x2c [ 7.985172] netlink_unicast+0x2e8/0x340 [ 7.989197] netlink_sendmsg+0x1a8/0x420 [ 7.993222] ____sys_sendmsg+0x218/0x280 [ 7.997249] ___sys_sendmsg+0xac/0x100 [ 8.001103] __sys_sendmsg+0x84/0xe0 [ 8.004776] __arm64_sys_sendmsg+0x24/0x30 [ 8.008983] invoke_syscall+0x48/0x114 [ 8.012840] el0_svc_common.constprop.0+0xcc/0xec [ 8.017665] do_el0_svc+0x38/0xb0 [ 8.021071] el0_svc+0x2c/0x84 [ 8.024212] el0t_64_sync_handler+0xf4/0x120 [ 8.028598] el0t_64_sync+0x190/0x194 Go back to the original behavior, if the automotive safety package is found to be supported in hardware enable all the features unless safety_feat_cfg is passed in saying this particular platform only supports a subset of the features.

CPT HW would trigger the CPT AF FLT interrupt when CPT engines hits some uncorrectable errors and AF is the one which receives the interrupt and recovers the engines.

2023-01-20octeontx2-af: update cpt lf alloc mailboxSrujana Challa
The CN10K CPT coprocessor contains a context processor to accelerate updates to the IPsec security association contexts. The context processor contains a context cache. This patch updates CPT LF ALLOC mailbox to config ctx_ilen requested by VFs. CPT_LF_ALLOC:ctx_ilen is the size of initial context fetch.

2023-01-20octeontx2-af: restore rxc conf after teardown sequenceNithin Dabilpuram
CN10K CPT coprocessor includes a component named RXC which is responsible for reassembly of inner IP packets. RXC has the feature to evict oldest entries based on age/threshold. The age/threshold is being set to minimum values to evict all entries at the time of teardown. This patch adds code to restore timeout and threshold config after teardown sequence is complete as it is global config.

2023-01-20octeontx2-af: modify FLR sequence for CPTSrujana Challa
On OcteonTX2 platform CPT instruction enqueue is only possible via LMTST operations. The existing FLR sequence mentioned in HRM requires a dummy LMTST to CPT but LMTST can't be submitted from AF driver. So, HW team provided a new sequence to avoid dummy LMTST. This patch adds code for the same. Signed-off-by: Srujana Challa <schalla@marvell.com> Signed-off-by: David S. Miller <davem@davemloft.net>
