2017-05-30HID: intel_ish-hid: convert timespec to ktime_tArnd Bergmann
The internal accounting uses 'timespec' based time stamps, which is slightly inefficient and also problematic once we get to the time_t overflow in 2038. When communicating to the firmware, we even get an open-coded 64-bit division that prevents the code from being build-tested on 32-bit architectures and is inefficient due to the double conversion from 64-bit nanoseconds to seconds+nanoseconds and then microseconds. This changes the code to use ktime_t instead.

2017-02-08HID: intel-ish-hid: ipc: check FW status to distinguish ISH resume pathsEven Xu
For ISH resume, there are two paths, they need different way to handle: one where ISH is not powered off, in that case a simple resume message is enough, in other case we need a reset sequence. We can use ISH FW status to distinguish those two cases and handle them properly.

2017-01-02HID: intel-ish-hid: add printf attribute to print_log()Nicolas Iooss
Structure ishtp_device contains a logging function, print_log(), which formats some of its parameters using vsnprintf(). Add a __printf attribute to this function field (and to ish_event_tracer()) in order to detect at compile time issues related to the printf-like formatting. While at it, make format parameter a const pointer as print_log() is not supposed to modify it.

2016-11-16HID: intel-ish-hid: ipc: use msleep_interrupt() for waitEven Xu
set_current_task() must be called before schedule_timeout(), for this driver, in order to avoid incorrect usage, use msleep_interrupt() instead.

2016-11-16HID: intel-ish-hid: ipc: change timed_wait_for_timeout() to be a functionEven Xu
The macro timed_wait_for_timeout() only be used in one function, so move this marco from header file and change it to a function in ipc.c, where it is used.

2016-11-05HID: intel-ish-hid: initialize ts_format.reservedJiri Kosina
ts_format.reserved is not used anywhere yet, but the compiler generates a warning when the struct's (uninitialized) field is being copied around drivers/hid/intel-ish-hid/ipc/ipc.c: In function ‘write_ipc_from_queue’: drivers/hid/intel-ish-hid/ipc/ipc.c:316: warning: ‘ts_format.reserved’ may be used uninitialized in this function Avoid this by force-initializing the field to zero.

2016-11-05HID: intel-ish-hid: request_irq failureSrinivas Pandruvada
On some platforms ISH interrupt is shared, which causes request_irq to fail. This requires IRQF_SHARED irq flag. But IRQF_NO_SUSPEND and IRQF_SHARED should not be used together, so removed IRQF_NO_SUSPEND flag. Anyway this driver doesn't require IRQF_NO_SUSPEND, as this interrupt is not required during "noirq" phases of suspending and resuming devices as well as during the time when nonboot CPUs are taken offline and brought back online.

2016-11-05HID: intel-ish-hid: Fix driver reinit failureEven Xu
When built as a module, modprobe followed by rmmod can fail because DMA was still active. So to fix this, DMA needs to be disabled during module exit. This change disables DMA during modules exit and change the ISH PCI device status to D3.
