The ChipID IO region has it's own clock, which is being disabled while scanning for unused clocks. It turned out that some CPU hotplug, CPU idle or even SOC firmware code depends on the reads from that area. Fix the mysterious hang caused by entering deep CPU idle state by ignoring the 'chipid' clock during unused clocks scan, as there are no direct clients for it which will keep it enabled.

2020-09-22USB: gadget: f_ncm: Fix NDP16 datagram validationBryan O'Donoghue
commit 2b74b0a04d3e ("USB: gadget: f_ncm: add bounds checks to ncm_unwrap_ntb()") adds important bounds checking however it unfortunately also introduces a bug with respect to section 3.3.1 of the NCM specification. wDatagramIndex[1] : "Byte index, in little endian, of the second datagram described by this NDP16. If zero, then this marks the end of the sequence of datagrams in this NDP16." wDatagramLength[1]: "Byte length, in little endian, of the second datagram described by this NDP16. If zero, then this marks the end of the sequence of datagrams in this NDP16." wDatagramIndex[1] and wDatagramLength[1] respectively then may be zero but that does not mean we should throw away the data referenced by wDatagramIndex[0] and wDatagramLength[0] as is currently the case. Breaking the loop on (index2 == 0 || dg_len2 == 0) should come at the end as was previously the case and checks for index2 and dg_len2 should be removed since zero is valid. I'm not sure how much testing the above patch received but for me right now after enumeration ping doesn't work. Reverting the commit restores ping, scp, etc. The extra validation associated with wDatagramIndex[0] and wDatagramLength[0] appears to be valid so, this change removes the incorrect restriction on wDatagramIndex[1] and wDatagramLength[1] restoring data processing between host and device.

The lldd may have made calls to delete a remote port or local port and the delete is in progress when the cli then attempts to create a new controller.

2020-09-22nvme-pci: fix NULL req in completion handlerXianting Tian
Currently, we use nvmeq->q_depth as the upper limit for a valid tag in nvme_handle_cqe(), it is not correct. Because the available tag number is recorded in tagset, which is not equal to nvmeq->q_depth. The nvme driver registers interrupts for queues before initializing the tagset, because it uses the number of successful request_irq() calls to configure the tagset parameters. This allows a race condition with the current tag validity check if the controller happens to produce an interrupt with a corrupted CQE before the tagset is initialized. Replace the driver's indirect tag check with the one already provided by the block layer.

2020-09-22can: flexcan: add ISO CAN FD feature supportJoakim Zhang
ISO CAN FD is introduced to increase the failture detection capability than non-ISO CAN FD. The non-ISO CAN FD is still supported by FlexCAN so that it can be used mainly during an intermediate phase, for evaluation and development purposes. Therefore, it is strongly recommended to configure FlexCAN to the ISO CAN FD protocol by setting the ISOCANFDEN field in the CTRL2 register. NOTE: If you only set "fd on", driver will use ISO FD mode by default. You should set "fd-non-iso on" after setting "fd on" if you want to use NON ISO FD mode.

2020-09-22can: flexcan: add LPSR mode supportJoakim Zhang
On the i.MX7D in LPSR mode, the controller will be powered off and the configuration state is lost after system resume. Upcoming i.MX8QM/QXP will also completely power off the domain, the controller state is lost and needs restore, too. So we need to set the pinctrl state again and re-start chip to re-configuration after resume. For the wakeup case, it should not set pinctrl to sleep state by pinctrl_pm_select_sleep_state. If the interface is down before suspend, we don't need to re-configure it as it will be configured if the interface is brought up later.

2020-09-22can: flexcan: add correctable errors correction when HW supports ECCJoakim Zhang
commit cdce844865be ("can: flexcan: add vf610 support for FlexCAN") From above commit by Stefan Agner, the patch just disables non-correctable errors interrupt and freeze mode. It still can correct the correctable errors since ECC enabled by default after reset (MECR[ECCDIS]=0, enable memory error correct) if HW supports ECC. commit 5e269324db5a ("can: flexcan: disable completely the ECC mechanism") From above commit by Joakim Zhang, the patch disables ECC completely (assert MECR[ECCDIS]) according to the explanation of FLEXCAN_QUIRK_DISABLE_MECR that disable memory error detection. This cause correctable errors cannot be corrected even HW supports ECC. The error correction mechanism ensures that in this 13-bit word, errors in one bit can be corrected (correctable errors) and errors in two bits can be detected but not corrected (non-correctable errors). Errors in more than two bits may not be detected. If HW supports ECC, we can use this to correct the correctable errors detected from FlexCAN memory. Then disable non-correctable errors interrupt and freeze mode to avoid that put FlexCAN in freeze mode. This patch adds correctable errors correction when HW supports ECC, and modify explanation for FLEXCAN_QUIRK_DISABLE_MECR.

Andy reported that commit 6b41030fdc79 ("dmaengine: dmatest: Restore default for channel") broke his scripts for the case where "busy" channel is used for configuration with expectation that run command would do nothing. Instead, behavior was (unintentionally) changed to treat such case as under-configuration and progress with defaults, i.e. run command would start a test with default setting for channel (which would use all channels). Restore original behavior with tracking status of channel setter so we can distinguish between misconfigured and under-configured cases in run command and act accordingly.

If CONFIG_ATH11K_DEBUGFS is disabled there are warnings debug.c: drivers/net/wireless/ath/ath11k/debug.c:36:20: warning: 'htt_bp_lmac_ring' defined but not used [-Wunused-variable] 36 | static const char *htt_bp_lmac_ring[HTT_SW_LMAC_RING_IDX_MAX] = { | ^~~~~~~~~~~~~~~~ drivers/net/wireless/ath/ath11k/debug.c:15:20: warning: 'htt_bp_umac_ring' defined but not used [-Wunused-variable] 15 | static const char *htt_bp_umac_ring[HTT_SW_UMAC_RING_IDX_MAX] = { | ^~~~~~~~~~~~~~~~ Fix this by refactoring debugfs code to debugfs.c. This also reduces the number of ifdefs in debug.c and makes it easier to maintain the code. No functional changes. Compile tested only.

2020-09-22wcn36xx: Ensure spaces between functionsBryan O'Donoghue
This is a small update to fix an error I saw where a few functions do not have a blank line in between them. Affects smd.c and main.c - no logic is affected by this change.

2020-09-22wcn36xx: Mark internal smd functions staticBryan O'Donoghue
This commit marks all smd.c functions that are only used inside of smd.c as static. Previous commits added some VHT specific setup functions non-static which is the right thing to do in terms of having granular git commits that compile warning free. What we really want is for local not global scope on those functions. This patch makes the conversion from global to local scope.

2020-09-22wcn36xx: Advertise ieee802.11 VHT flagsBryan O'Donoghue
This patch adds ieee802.11 VHT flags for the wcn3680b. - RX_STBC1 - SU Beamformee - MU Beamformee - VHT80 SGI - Single spatial stream RX LDPC is declared as supported in the datasheet but not enabled at this time. After this patch is applied an AP should see the wcn3680 as an 802.11ac capable device.

2020-09-22wcn36xx: Add VHT rates to wcn36xx_update_allowed_rates()Bryan O'Donoghue
This commit adds VHT rates to the wcn36xx_update_allowed_rates() routine. Thus allowing the driver to latch the declared rates and transmit them to the firmware in the same way as other 80211.n rates are.

2020-09-22wcn36xx: Convert to VHT parameter structure on wcn3680Bryan O'Donoghue
In order to send VHT parameters to wcn3680 we need to pass the extended V1 parameter structures to the firmware. These commands need to have the version number set to 1. This patch makes the conversion. The conversion consists of 1. Setting the version number for wcn3680 or leaving it at 0 otherwise 2. Setting the size of the packet header lower for wcn3620 and wcn3660 Once done all three chips can continue to use the same code to pass parameters to their respective firmware. In the case of the wcn3680 the passed structures will be slightly larger to accommodate communication of VHT descriptors.

2020-09-22wcn36xx: Define INIT_HAL_MSG_V1()Bryan O'Donoghue
In order to pass 802.11ac VHT parameters from the SoC to wcn36xx we need to use the V1 data structures associated with BSS and STA parameters. The means of identifying a V1 data-structure is via the SMD version field. This patch defines a INIT_HAL_MSG_V1() which operates the same way as INIT_HAL_MSG() with the exception that it defines VERSION1 as opposed to VERSION0.
