2021-08-16power: supply: smb347-charger: Add missing pin control activationDmitry Osipenko
Pin control needs to be activated by setting the enable bit, otherwise hardware rejects all pin changes. Previously this stayed unnoticed on Nexus 7 because pin control was enabled by default after rebooting from downstream kernel, which uses driver that enables the bit and charger registers are non-volatile until power supply (battery) is disconnected. Configure the pin control enable bit. This fixes the potentially never-enabled charging on devices that use pin control.

2021-08-16power: supply: smb347-charger: Make smb347_set_writable() IRQ-safeDmitry Osipenko
The smb347_set_writable() is used by interrupt handler and outside of it. The interrupt should be disabled when the function is used outside of interrupt handler in order to prevent racing with the interrupt context. Add new parameter to smb347_set_writable() that allows to disable IRQ. Signed-off-by: Dmitry Osipenko <digetx@gmail.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.com>

2021-08-16spi: orion: Prevent incorrect chip select behaviourNathan Rossi
When clearing the chip-select mask, the controller will switch to chip selecting the native CS0 line. Because the control register chip-select mask is not updated in a single write this will cause undesirable chip-selection of CS0 even when requesting to select other native chip-select lines. This is additionally problematic as the chip-select may still be asserted. With the ARMADA 38x SoC the controller will assert both the desired native chip-select and CS0. To avoid any undesirable behaviour with the chip-select lines, update the control register with a single write. This avoids selecting CS0 and causes the (de-)assert to apply at the same time.

2021-08-16drm: ttm: Don't bail from ttm_global_init if debugfs_create_dir failsDan Moulding
In 69de4421bb4c ("drm/ttm: Initialize debugfs from ttm_global_init()"), ttm_global_init was changed so that if creation of the debugfs global root directory fails, ttm_global_init will bail out early and return an error, leading to initialization failure of DRM drivers. However, not every system will be using debugfs. On such a system, debugfs directory creation can be expected to fail, but DRM drivers must still be usable. This changes it so that if creation of TTM's debugfs root directory fails, then no biggie: keep calm and carry on.

2021-08-16bnxt_en: Add missing DMA memory barriersMichael Chan
Each completion ring entry has a valid bit to indicate that the entry contains a valid completion event. The driver's main poll loop __bnxt_poll_work() has the proper dma_rmb() to make sure the valid bit of the next entry has been checked before proceeding further. But when we call bnxt_rx_pkt() to process the RX event, the RX completion event consists of two completion entries and only the first entry has been checked to be valid. We need the same barrier after checking the next completion entry. Add missing dma_rmb() barriers in bnxt_rx_pkt() and other similar locations.

There is a known bug on BCM2711's SDHCI core integration where the controller will hang when the difference between the core clock and the bus clock is too great. Specifically this can be reproduced under the following conditions: - No SD card plugged in, polling thread is running, probing cards at 100 kHz. - BCM2711's core clock configured at 500MHz or more. So set 200 kHz as the minimum clock frequency available for that board.

2021-08-13soc: fsl: qe: fix static checker warningMaxim Kochetkov
The patch be7ecbd240b2: "soc: fsl: qe: convert QE interrupt controller to platform_device" from Aug 3, 2021, leads to the following static checker warning: drivers/soc/fsl/qe/qe_ic.c:438 qe_ic_init() warn: unsigned 'qe_ic->virq_low' is never less than zero. In old variant irq_of_parse_and_map() returns zero if failed so unsigned int for virq_high/virq_low was ok. In new variant platform_get_irq() returns negative error codes if failed so we need to use int for virq_high/virq_low. Also simplify high_handler checking and remove the curly braces to make checkpatch happy.

2021-08-13bnxt: make sure xmit_more + errors does not miss doorbellsJakub Kicinski
skbs are freed on error and not put on the ring. We may, however, be in a situation where we're freeing the last skb of a batch, and there is a doorbell ring pending because of xmit_more() being true earlier. Make sure we ring the door bell in such situations. Since errors are rare don't pay attention to xmit_more() and just always flush the pending frames. The busy case should be safe to be left alone because it can only happen if start_xmit races with completions and they both enable the queue. In that case the kick can't be pending. Noticed while reading the code. Fixes: 4d172f21cefe ("bnxt_en: Implement xmit_more.")

2021-08-13bnxt: don't lock the tx queue from napi pollJakub Kicinski
We can't take the tx lock from the napi poll routine, because netpoll can poll napi at any moment, including with the tx lock already held. The tx lock is protecting against two paths - the disable path, and (as Michael points out) the NETDEV_TX_BUSY case which may occur if NAPI completions race with start_xmit and both decide to re-enable the queue. For the disable/ifdown path use synchronize_net() to make sure closing the device does not race we restarting the queues. Annotate accesses to dev_state against data races. For the NAPI cleanup vs start_xmit path - appropriate barriers are already in place in the main spot where Tx queue is stopped but we need to do the same careful dance in the TX_BUSY case.
