commit b027ce25 upstream. hci_qca interfaces to the wcn3990 via a uart_dm on the msm8998 mtp and Lenovo Miix 630 laptop. As part of initializing the wcn3990, hci_qca disables flow, configures the uart baudrate, and then reenables flow - at which point an event is expected to be received over the uart from the wcn3990. It is observed that this event comes after the baudrate change but before hci_qca re-enables flow. This is unexpected, and is a result of msm_reset() being broken. According to the uart_dm hardware documentation, it is recommended that automatic hardware flow control be enabled by setting RX_RDY_CTL. Auto hw flow control will manage RFR based on the configured watermark. When there is space to receive data, the hw will assert RFR. When the watermark is hit, the hw will de-assert RFR. The hardware documentation indicates that RFR can me manually managed via CR when RX_RDY_CTL is not set. SET_RFR asserts RFR, and RESET_RFR de-asserts RFR. msm_reset() is broken because after resetting the hardware, it unconditionally asserts RFR via SET_RFR. This enables flow regardless of the current configuration, and would undo a previous flow disable operation. It should instead de-assert RFR via RESET_RFR to block flow until the hardware is reconfigured. msm_serial should rely on the client to specify that flow should be enabled, either via mctrl() or the termios structure, and only assert RFR in response to those triggers.

commit 487ee861 upstream. The dmaengine_prep_slave_sg needs to use sg count returned by dma_map_sg, not use sport->dma_tx_nents, because the return value of dma_map_sg is not always same with "nents". When enabling iommu for lpuart + edma, iommu framework may concatenate two sgs into one.

commit 45a2d646 upstream. The layout of struct timeval is different on sparc64 from anything else, and the patch I did long ago failed to take this into account. Change it now to handle sparc64 user space correctly again. Quite likely nobody cares about parallel ports on sparc64, but there is no reason not to fix it.

commit 1e5e929c upstream. Commit 34993594 ("arm64: tegra: Enable HDMI on Jetson TX1") added a regulator for HDMI on the Jetson TX1 platform. This regulator has an active high enable, but the GPIO specifier for enabling the regulator incorrectly defines it as active-low. This causes the following warning to occur on boot ... WARNING KERN regulator@10 GPIO handle specifies active low - ignored The fixed-regulator binding does not use the active-low flag from the gpio specifier and purely relies of the presence of the 'enable-active-high' property to determine if it is active high or low (if this property is omitted). Fix this warning by setting the GPIO to active-high in the GPIO specifier which aligns with the presense of the 'enable-active-high' property.

commit a31eda65 upstream. pm_runtime_put_autosuspend in probe will call runtime suspend to disable clks automatically if CONFIG_PM is defined. (If CONFIG_PM is not defined, its implementation will be empty, then runtime suspend will not be called.) Therefore, we can call pm_runtime_get_sync to runtime resume it first to enable clks, which matches the runtime suspend. (Only when CONFIG_PM is defined, otherwise pm_runtime_get_sync will also be empty, then runtime resume will not be called.) Then it is fine to disable clks without causing clock count mis-match.

commit f3e4f3fc upstream. The AML code implementing the WMI methods creates a variable length field to hold the input data we pass like this: CreateDWordField (Arg1, 0x0C, DSZI) Local5 = DSZI /* \HWMC.DSZI */ CreateField (Arg1, 0x80, (Local5 * 0x08), DAIN) If we pass 0 as bios_args.datasize argument then (Local5 * 0x08) is 0 which results in these errors: [ 71.973305] ACPI BIOS Error (bug): Attempt to CreateField of length zero (20190816/dsopcode-133) [ 71.973332] ACPI Error: Aborting method \HWMC due to previous error (AE_AML_OPERAND_VALUE) (20190816/psparse-529) [ 71.973413] ACPI Error: Aborting method \_SB.WMID.WMAA due to previous error (AE_AML_OPERAND_VALUE) (20190816/psparse-529) And in our HPWMI_WIRELESS2_QUERY calls always failing. for read commands like HPWMI_WIRELESS2_QUERY the DSZI value is not used / checked, except for read commands where extra input is needed to specify exactly what to read. So for HPWMI_WIRELESS2_QUERY we can safely pass the size of the expected output as insize to hp_wmi_perform_query(), as we are already doing for all other HPWMI_READ commands we send. Doing so fixes these errors.

commit 16245db1 upstream. The HP WMI calls may take up to 128 bytes of data as input, and the AML methods implementing the WMI calls, declare a couple of fields for accessing input in different sizes, specifycally the HWMC method contains: CreateField (Arg1, 0x80, 0x0400, D128) Even though we do not use any of the WMI command-types which need a buffer of this size, the APCI interpreter still tries to create it as it is declared in generoc code at the top of the HWMC method which runs before the code looks at which command-type is requested. This results in many of these errors on many different HP laptop models: [ 14.459261] ACPI Error: Field [D128] at 1152 exceeds Buffer [NULL] size 160 (bits) (20170303/dsopcode-236) [ 14.459268] ACPI Error: Method parse/execution failed [\HWMC] (Node ffff8edcc61507f8), AE_AML_BUFFER_LIMIT (20170303/psparse-543) [ 14.459279] ACPI Error: Method parse/execution failed [\_SB.WMID.WMAA] (Node ffff8edcc61523c0), AE_AML_BUFFER_LIMIT (20170303/psparse-543) This commit increases the size of the data element of the bios_args struct to 128 bytes fixing these errors.

commit 1cb0d2ae upstream. Upstream commit 58e75155 ("HID: core: move Usage Page concatenation to Main item") adds support for Usage Page item after Usage ID items (such as keyboards manufactured by Primax). Usage Page concatenation in Main item works well for following report descriptor patterns: USAGE_PAGE (Keyboard) 05 07 USAGE_MINIMUM (Keyboard LeftControl) 19 E0 USAGE_MAXIMUM (Keyboard Right GUI) 29 E7 LOGICAL_MINIMUM (0) 15 00 LOGICAL_MAXIMUM (1) 25 01 REPORT_SIZE (1) 75 01 REPORT_COUNT (8) 95 08 INPUT (Data,Var,Abs) 81 02 ------------- USAGE_MINIMUM (Keyboard LeftControl) 19 E0 USAGE_MAXIMUM (Keyboard Right GUI) 29 E7 LOGICAL_MINIMUM (0) 15 00 LOGICAL_MAXIMUM (1) 25 01 REPORT_SIZE (1) 75 01 REPORT_COUNT (8) 95 08 USAGE_PAGE (Keyboard) 05 07 INPUT (Data,Var,Abs) 81 02 But it makes the parser act wrong for the following report descriptor pattern(such as some Gamepads): USAGE_PAGE (Button) 05 09 USAGE (Button 1) 09 01 USAGE (Button 2) 09 02 USAGE (Button 4) 09 04 USAGE (Button 5) 09 05 USAGE (Button 7) 09 07 USAGE (Button 8) 09 08 USAGE (Button 14) 09 0E USAGE (Button 15) 09 0F USAGE (Button 13) 09 0D USAGE_PAGE (Consumer Devices) 05 0C USAGE (Back) 0a 24 02 USAGE (HomePage) 0a 23 02 LOGICAL_MINIMUM (0) 15 00 LOGICAL_MAXIMUM (1) 25 01 REPORT_SIZE (1) 75 01 REPORT_COUNT (11) 95 0B INPUT (Data,Var,Abs) 81 02 With Usage Page concatenation in Main item, parser recognizes all the 11 Usages as consumer keys, it is not the HID device's real intention. This patch checks whether Usage Page is really defined after Usage ID items by comparing usage page using status. Usage Page concatenation on currently defined Usage Page will always do in local parsing when Usage ID items encountered. When Main item is parsing, concatenation will do again with last defined Usage Page if this page has not been used in the previous usages concatenation. Signed-off-by:
