If an interrupt is raised while the EFR is mapped in then the ISR won't be able to access the IIR, leading to the "Unexpected interrupt" error messages. Avoid the problem by claiming a mutex around accesses to the EFR register, also claiming the mutex in the interrupt handler work item (this is equivalent to disabling interrupts to interlock against a non-threaded interrupt handler).

At 192kHz only 128xfs is supported. The existing driver selects 128xfs automatically for some lower samples rates. By using an additional mclk_div divider, it is now possible to control the behaviour. This allows using 256xfs PLL frequency on all sample rates up to 96kHz. It should allow lower jitter and better signal quality. The behavior has to be controlled by the sound card driver, because some sample frequency share the same setting. e.g. 192kHz and 96kHz use 24.576MHz master clock. The only difference is the MCLK divider. This also added support for 32bit data. Signed-off-by: Daniel Matuschek <daniel@matuschek.net> | 29 August 2018, 12:31:06 UTC |

FIQ_START at boot-time ad83c7cb2f37 ("irqchip/irq-bcm2836: Add support for DT interrupt polarity") changed the way that the BCM2836/7 local interrupts are mapped; instead of being pre-mapped they are now mapped on-demand. A side effect of this change is that the call to irq_of_parse_and_map from armctrl_of_init creates a new mapping, forming a gap between the IRQs and the FIQs. This gap breaks the FIQ<->IRQ mapping which up to now has been done by assuming: 1) that the value of FIQ_START is the same as the number of normal IRQs that will be mapped (still true), and 2) that this value is also the offset between an IRQ and its equivalent FIQ (which is no longer the case). Remove both assumptions by measuring the interval between the last IRQ and the last FIQ, passing it as the parameter to init_FIQ().

| eb27436 | Noralf Trønnes | 24 February 2018, 12:41:25 UTC | firmware/raspberrypi: Add a get_throttled sysfs file Under-voltage due to inadequate power supplies is a recurring problem for new Raspberry Pi users. There are visual indications that an under-voltage situation is occuring like blinking power led and a lightning icon on the desktop (not shown when using the vc4 driver), but for new users it's not obvious that this signifies a critical situation. This patch provides a twofold improvement to the situation: Firstly it logs under-voltage events to the kernel log. This provides information also for headless installations. Secondly it provides a sysfs file to read the value. This improves on 'vcgencmd' by providing change notification. Userspace can poll on the file and be notified of changes to the value. A script can poll the file and use dbus notification to put a windows on the desktop with information about the severity with a recommendation to change the power supply. A link to more information can also be provided. Only changes to the sticky bits are reported (cleared between readings). Signed-off-by: Noralf Trønnes <noralf@tronnes.org> Prevent voltage low warnings from filling log Although the correct fix for low voltage warnings is to improve the power supply, the current implementation of the detection can fill the log if the warning happens freqently. This replaces the logging with slightly custom ratelimited logging. Signed-off-by: James Hughes <james.hughes@raspberrypi.org> Reduce log spam when mailbox call not implemented This changes the logging message when a mailbox call fails to the dev_dbg level. In addition, it fixes the low voltage detection logging code so that if the mailbox call doies fails, it logs at error level and flags so the call is no longer attempted.

| a83f929 | Phil Elwell | 20 February 2018, 11:48:15 UTC | sc16is7xx: Fix for multi-channel stall The SC16IS752 is a dual-channel device. The two channels are largely independent, but the IRQ signals are wired together as an open-drain, active low signal which will be driven low while either of the channels requires attention, which can be for significant periods of time until operations complete and the interrupt can be acknowledged. In that respect it is should be treated as a true level-sensitive IRQ. The kernel, however, needs to be able to exit interrupt context in order to use I2C or SPI to access the device registers (which may involve sleeping). Therefore the interrupt needs to be masked out or paused in some way. The usual way to manage sleeping from within an interrupt handler is to use a threaded interrupt handler - a regular interrupt routine does the minimum amount of work needed to triage the interrupt before waking the interrupt service thread. If the threaded IRQ is marked as IRQF_ONESHOT the kernel will automatically mask out the interrupt until the thread runs to completion. The sc16is7xx driver used to use a threaded IRQ, but a patch switched to using a kthread_worker in order to set realtime priorities on the handler thread and for other optimisations. The end result is non-threaded IRQ that schedules some work then returns IRQ_HANDLED, making the kernel think that all IRQ processing has completed. The work-around to prevent a constant stream of interrupts is to mark the interrupt as edge-sensitive rather than level-sensitive, but interpreting an active-low source as a falling-edge source requires care to prevent a total cessation of interrupts. Whereas an edge-triggering source will generate a new edge for every interrupt condition a level-triggering source will keep the signal at the interrupting level until it no longer requires attention; in other words, the host won't see another edge until all interrupt conditions are cleared. It is therefore vital that the interrupt handler does not exit with an outstanding interrupt condition, otherwise the kernel will not receive another interrupt unless some other operation causes the interrupt state on the device to be cleared. The existing sc16is7xx driver has a very simple interrupt "thread" (kthread_work job) that processes interrups on each channel in turn until there are no more. If both channels are active and the first channel starts interrupting while the handler for the second channel is running then it will not be detected and an IRQ stall ensues. This could be handled easily if there was a shared IRQ status register, or a convenient way to determine if the IRQ had been deasserted for any length of time, but both appear to be lacking. Avoid this problem (or at least make it much less likely to happen) by reducing the granularity of per-channel interrupt processing to one condition per iteration, only exiting the overall loop when both channels are no longer interrupting.

| f1f1a74 | Phil Elwell | 20 February 2018, 10:07:27 UTC | i2c-gpio: Also set bus numbers from reg property I2C busses can be assigned specific bus numbers using aliases in Device Tree - string properties where the name is the alias and the value is the path to the node. The current DT parameter mechanism does not allow property names to be derived from a parameter value in any way, so it isn't possible to generate unique or matching aliases for nodes from an overlay that can generate multiple instances, e.g. i2c-gpio. Work around this limitation (at least temporarily) by allowing the i2c adapter number to be initialised from the "reg" property if present.
