Currently, SR_TCF flag is checked in case there is data, this criteria is not correct. SR_TCF flags is set when programmed number of bytes has been transferred to the memory device ("bytes" comprised command and data send to the SPI device). So even if there is no data, we must check SR_TCF flag.

The controller may have been left out of reset by the bootloader, in which case, before the powerup sequence, the controller will be found preconfigured with values that were set before booting the kernel: this produces a controller failure, with the result of a failure during the mtk_pcie_startup_port() sequence as the PCIe link never gets up. To ensure that we get a clean start in an expected state, assert both the PHY and MAC resets before executing the controller power-up sequence.

2022-05-11PCI: imx6: Fix PERST# start-up sequenceFrancesco Dolcini
According to the PCIe standard the PERST# signal (reset-gpio in fsl,imx* compatible dts) should be kept asserted for at least 100 usec before the PCIe refclock is stable, should be kept asserted for at least 100 msec after the power rails are stable and the host should wait at least 100 msec after it is de-asserted before accessing the configuration space of any attached device. From PCIe CEM r2.0, sec 2.6.2 T-PVPERL: Power stable to PERST# inactive - 100 msec T-PERST-CLK: REFCLK stable before PERST# inactive - 100 usec. From PCIe r5.0, sec 6.6.1 With a Downstream Port that does not support Link speeds greater than 5.0 GT/s, software must wait a minimum of 100 ms before sending a Configuration Request to the device immediately below that Port. Failure to do so could prevent PCIe devices to be working correctly, and this was experienced with real devices. Move reset assert to imx6_pcie_assert_core_reset(), this way we ensure that PERST# is asserted before enabling any clock, move de-assert to the end of imx6_pcie_deassert_core_reset() after the clock is enabled and deemed stable and add a new delay of 100 msec just afterward.

2022-05-11HID: apple: Properly handle function keys on Keychron keyboardsBryan Cain
Keychron's C-series and K-series of keyboards copy the vendor and product IDs of an Apple keyboard, but only behave like that device when set to "Mac" mode. In "Windows" mode, the Fn key doesn't generate a scancode, so it's impossible to use the F1-F12 keys when fnmode is set to its default value of 1. To fix this, make fnmode default to the new value of 3, which behaves like fnmode=2 for Keychron keyboards and like fnmode=1 for actual Apple keyboards. This way, Keychron devices are fully usable in both "Windows" and "Mac" modes, while behavior is unchanged for everything else.

2022-05-11PCI: qcom-ep: Move enable/disable resources code to common functionsDmitry Baryshkov
Remove code duplication by moving the code related to enabling/disabling the resources (PHY, CLK, Reset) to common functions so that they can be called from multiple places. [mani: renamed the functions and reworded the commit message] Link: https://lore.kernel.org/r/20220502104938.97033-1-manivannan.sadhasivam@linaro.org Signed-off-by: Dmitry Baryshkov <dmitry.baryshkov@linaro.org> Signed-off-by: Manivannan Sadhasivam <manivannan.sadhasivam@linaro.org> Signed-off-by: Lorenzo Pieralisi <lorenzo.pieralisi@arm.com>
2022-05-11perf/arm-cmn: Fix filter_sel lookupRobin Murphy
Carefully considering the bounds of an array is all well and good, until you forget that that array also contains a NULL sentinel at the end and dereference it. So close...

2022-05-11wfx: use container_of() to get vifJaehee Park
Currently, upon virtual interface creation, wfx_add_interface() stores a reference to the corresponding struct ieee80211_vif in private data, for later usage. This is not needed when using the container_of construct. This construct already has all the info it needs to retrieve the reference to the corresponding struct from the offset that is already available, inherent in container_of(), between its type and member inputs (struct ieee80211_vif and drv_priv, respectively). Remove vif (which was previously storing the reference to the struct ieee80211_vif) from the struct wfx_vif, define a function wvif_to_vif(wvif) for container_of(), and replace all wvif->vif with the newly defined container_of construct.
