This code generates a waring as PHY_GBIT_FEATURES is "long" but ->supported in "int". It looks likely that "PHY_1000BT_FEATURES" is the correct define to use - it is intended to be used with the ->features field.

Since commit bb276262 ("mtd: spi-nor: only apply reset hacks to broken hardware"), we need to mark the spi-nor as "broken" for reboot to work. Note that nothing is actually broken here. The hardware-watchdog in the SoC isn't wired in a way that works, but then the board doesn't claim to support a hardware watchdog - and the SPI certain isn't "broken". This causes an annoying warning on every boot, but that is better than failing on ever reboot.

I had started the removal of semaphores in this driver without knowing that Nicolas Saenz Julienne also worked on this. In case of the "remote event" infrastructure, my solution seemed significantly better, so I'm proposing this as a change on top. The problem with using either semaphores or completions here is that it's an overly complex way of waking up a thread, and it looks like the 'count' of the semaphore can easily get out of sync, even though I found it hard to come up with a specific example. Changing it to a 'wait_queue_head_t' instead of a completion simplifies this by letting us wait directly on the 'event->fired' variable that is set by the videocore. Another simplification is passing the wait queue directly into the helper functions instead of going through the fragile logic of recording the offset inside of a structure as part of a shared memory variable. This also avoids one uncached memory read and should be faster. Note that I'm changing it back to 'killable' after the previous patch changed 'killable' to 'interruptible', apparently based on a misunderstanding of the subtle down_interruptible() macro override in vchiq_killable.h.

This driver uses many semaphores, most of them are equivalent to completions. The other copies of this driver got moved over to completions a while ago, so do the same here. In this usage scenario, the two are equivalent, so the behavior should not change.

Changes do_insn*_ioctl functions to allow for data lengths for each comedi_insn of up to 2^16. This patch also changes these functions to only allocate as much memory as is necessary for each comedi_insn, rather than allocating a fixed-sized scratch space. In testing some user-space code for the new INSN_DEVICE_CONFIG_GET_ROUTES facility with some newer hardware, I discovered that do_insn_ioctl and do_insnlist_ioctl limited the amount of data that can be passed into the kernel for insn's to a length of 256. For some newer hardware, the number of routes can be greater than 1000. Working around the old limits (256) would complicate the user-space/kernel interaction. The new upper limit is reasonable with current memory available and does not otherwise impact the memory footprint for any current or otherwise typical configuration. Signed-off-by: Spencer E.

As explained in previous patch, this SPI controller seems to be tested on SPI flash only before mass production and some bits are swizzled under other SPI modes probably due to incorrect wiring inside the silicon. Drop implementation of SPI mode 1/2/3 since they are broken. Also drop RT2880_SPI_MODE_BITS macro because we now have only SPI_LSB_FIRST implemented and the mode_bits is so short that we don't need a macro there.

According to John Crispin (aka blogic) on IRC on Nov 26 2018: so basically i made cs1 work for MTK/labs when i built the linkit smart for them. the req-sheet said that cs1 should be proper duplex spi. however .... 1) the core will always send 1 byte before any transfer, this is the m25p80 command. 2) mode 3 is broken and bit reversed (?) 3) some bit are incorrectly wired in hw for mode2/3 we wrote a test script and test for [0-0xffff] on all modes and certain bits are swizzled under certain conditions and it was not possible to fix this even using a hack. we then decided to use spi-gpio and i never removed the errornous code basically the spi is fecked for anything but half duplex spi mode0 running a sflash on it The controller will always send some data from OPCODE register under half duplex mode before starting a full-duplex transfer, so the full-duplex mode is broken. This piece of code also make CS1 unavailable since it forces the broken full-duplex mode to be used on CS1.

The CP rings are accounted differently on the new 57500 chips. There must be enough CP rings for the sum of RX and TX rings on the new chips. The current logic may be over-estimating the RX and TX rings. The output parameter max_cp should be the maximum NQs capped by MSIX vectors available for networking in the context of 57500 chips. The existing code which uses CMPL rings capped by the MSIX vectors works most of the time but is not always correct. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S.

The new 57500 chips have introduced the NQ structure in addition to the existing CP rings in all chips. We need to introduce a new bnxt_nq_rings_in_use(). On legacy chips, the 2 functions are the same and one will just call the other. On the new chips, they refer to the 2 separate ring structures. The new function is now called to determine the resource (NQ or CP rings) associated with MSIX that are in use. On 57500 chips, the RDMA driver does not use the CP rings so we don't need to do the subtraction adjustment. Fixes: 41e8d798 ("bnxt_en: Modify the ring reservation functions for 57500 series chips.")

The new 57500 chips use 1 NQ per MSIX vector, whereas legacy chips use 1 CP ring per MSIX vector. To better unify this, add a resv_irqs field to struct bnxt_hw_resc. On legacy chips, we initialize resv_irqs with resv_cp_rings. On new chips, we initialize it with the allocated MSIX resources.

Recent changes to support the 57500 devices have created this regression. The bnxt_hwrm_queue_qportcfg() call was moved to be called earlier before the RDMA support was determined, causing the CoS queues configuration to be set before knowing whether RDMA was supported or not. Fix it by moving it to the right place right after RDMA support is determined. Fixes: 98f04cf0 ("bnxt_en: Check context memory requirements from firmware.")

Pull libnvdimm fixes from Dan Williams: "A regression fix for the Address Range Scrub implementation, yes another one, and support for platforms that misalign persistent memory relative to the Linux memory hotplug section constraint.

These have all appeared in a -next release, and thanks to Patrick for reporting and testing the alignment padding fix. Summary: - Unless and until the core mm handles memory hotplug units smaller than a section (128M), persistent memory namespaces must be padded to section alignment. The libnvdimm core already handled section collision with "System RAM", but some configurations overlap independent "Persistent Memory" ranges within a section, so additional padding injection is added for that case. - The recent reworks of the ARS (address range scrub) state machine to reduce the number of state flags inadvertantly missed a conversion of acpi_nfit_ars_rescan() call sites.
