[ Upstream commit 6d6b0d0d5afc8c4c84b08261260ba11dfa5206f2 ] When in slave mode, an arbitration loss (ARLO) may be detected before the slave had a chance to detect the stop condition (STOPF in ISR). This is seen when two master + slave adapters switch their roles. It provokes the i2c bus to be stuck, busy as SCL line is stretched. - the I2C_SLAVE_STOP event is never generated due to STOPF flag is set but don't generate an irq (race with ARLO irq, STOPIE is masked). STOPF flag remains set until next master xfer (e.g. when STOPIE irq get unmasked). In this case, completion is generated too early: immediately upon new transfer request (then it doesn't send all data). - Some data get stuck in TXDR register. As a consequence, the controller stretches the SCL line: the bus gets busy until a future master transfer triggers the bus busy / recovery mechanism (this can take time... and may never happen at all) So choice is to let the STOPF being detected by the slave isr handler, to properly handle this stop condition. E.g. don't mask IRQs in error handler, when the slave is running.

[ Upstream commit 8424312516e5d9baeeb0a95d0e4523579b7aa395 ] On a system without Single VMOVP support (say GITS_TYPER.VMOVP == 0), we will map vPEs only on ITSs that will actually control interrupts for the given VM. And when moving a vPE, the VMOVP command will be issued only for those ITSs. But when issuing VMOVPs we seemed fail to present the exact ITSList to ITSs who are actually included in the synchronization operation. The its_list_map we're currently using includes all ITSs in the system, even though some of them don't have the corresponding vPE mapping at all. Introduce get_its_list() to get the per-VM its_list_map, to indicate which ITSs have vPE mappings for the given VM, and use this map as the expected ITSList when building VMOVP. This is hopefully a performance gain not to do some synchronization with those unsuspecting ITSs. And initialize the whole command descriptor to zero at beginning, since the seq_num and its_list should be RES0 when GITS_TYPER.VMOVP == 1.

[ Upstream commit 2ecb287998a47cc0a766f6071f63bc185f338540 ] r0-r3 & r12 registers are saved & restored, before & after svc respectively. Intention was to preserve those registers across thread to handler mode switch. On v7-M, hardware saves the register context upon exception in AAPCS complaint way. Restoring r0-r3 & r12 is done from stack location where hardware saves it, not from the location on stack where these registers were saved. To clarify, on stm32f429 discovery board: 1. before svc, sp - 0x90009ff8 2. r0-r3,r12 saved to 0x90009ff8 - 0x9000a00b 3. upon svc, h/w decrements sp by 32 & pushes registers onto stack 4. after svc, sp - 0x90009fd8 5. r0-r3,r12 restored from 0x90009fd8 - 0x90009feb Above means r0-r3,r12 is not restored from the location where they are saved, but since hardware pushes the registers onto stack, the registers are restored correctly. Note that during register saving to stack (step 2), it goes past 0x9000a000. And it seems, based on objdump, there are global symbols residing there, and it perhaps can cause issues on a non-XIP Kernel (on XIP, data section is setup later). Based on the analysis above, manually saving registers onto stack is at best no-op and at worst can cause data section corruption. Hence remove storing of registers onto stack before svc.

[ Upstream commit ccdf3aaa27ded6db9a93eed3ca7468bb2353b8fe ] It turns out that sopine-baseboard needs same fix as pine64-plus for ethernet PHY. Here too Realtek ethernet PHY chip needs additional power on delay to properly initialize. Datasheet mentions that chip needs 30 ms to be properly powered on and that it needs some more time to be initialized. Fix that by adding 100ms ramp delay to regulator responsible for powering PHY. Note that issue was found out and fix tested on pine64-lts, but it's basically the same as sopine-baseboard, only layout and connectors differ.

[ Upstream commit 2511366797fa6ab4a404b4b000ef7cd262aaafe8 ] Depending on kernel and bootloader configuration, it's possible that Realtek ethernet PHY isn't powered on properly. According to the datasheet, it needs 30ms to power up and then some more time before it can be used. Fix that by adding 100ms ramp delay to regulator responsible for powering PHY.

[ Upstream commit ca2347190adb5e4eece73a2b16e96e651c46246b ] In case of WM1811 device there are currently being registered controls referring to registers not existing on that device. It has been noticed when getting values of "AIF1ADC2 Volume", "AIF1DAC2 Volume" controls was failing during ALSA state restoring at boot time: "amixer: Mixer hw:0 load error: Device or resource busy" Reading some registers through I2C was failing with EBUSY error and indeed these registers were not available according to the datasheet. To fix this controls not available on WM1811 are moved to a separate array and registered only for WM8994 and WM8958. There are some further differences between WM8994 and WM1811, e.g. registers 603h, 604h, 605h, which are not covered in this patch.

[ Upstream commit 131cb1210d4b58acb0695707dad2eb90dcb50a2a ] Currently the regulator-suspend-min/max-microvolt must be within the root regulator node but the dt-bindings specifies it as subnode properties for the regulator-state-[mem/disk/standby] node. The only DT using this bindings currently is the at91-sama5d2_xplained.dts and this DT uses it correctly. I don't know if it isn't tested but it can't work without this fix.

[ Upstream commit 1a7f60b9df614bb36d14dc0c0bc898a31b2b506f ] This reverts commit caa8422d01e983782548648e125fd617cadcec3f. It turned out that this commit caused a regression at shutdown / reboot, as the synchronize_irq() calls seems blocking the whole shutdown. Also another part of the change about shuffling the call order looks suspicious; the azx_stop_chip() call disables the CORB / RIRB while the others may still need the CORB/RIRB update. Since the original commit itself was a cargo-fix, let's revert the whole patch.

[ Upstream commit a39331867335d4a94b6165e306265c9e24aca073 ] When a card is disconnected while in use, the system waits until all opened files are closed then releases the card. This is done via put_device() of the card device in each device release code. The recently reported mutex deadlock bug happens in this code path; snd_timer_close() for the timer device deals with the global register_mutex and it calls put_device() there. When this timer device is the last one, the card gets freed and it eventually calls snd_timer_free(), which has again the protection with the global register_mutex -- boom. Basically put_device() call itself is race-free, so a relative simple workaround is to move this put_device() call out of the mutex. For achieving that, in this patch, snd_timer_close_locked() got a new argument to store the card device pointer in return, and each caller invokes put_device() with the returned object after the mutex unlock.
