2020-04-24platform/x86: intel_mid_powerbtn: Convert to use new SCU IPC APIMika Westerberg1-4/+11
This converts the power button driver to use the new SCU IPC API where the SCU IPC instance is passed to the functions. Signed-off-by: Mika Westerberg <mika.westerberg@linux.intel.com> Reviewed-by: Andy Shevchenko <andriy.shevchenko@linux.intel.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
2020-03-24platform/x86: Convert to new CPU match macrosThomas Gleixner1-2/+2
The new macro set has a consistent namespace and uses C99 initializers instead of the grufty C89 ones. Get rid the of the local macro wrappers for consistency.

2020-01-22platform/x86: intel_mid_powerbtn: Take a copy of ddataMika Westerberg1-2/+3
The driver gets driver_data from memory that is marked as const (which is probably put to read-only memory) and it then modifies it. This likely causes some sort of fault to happen. Fix this by taking a copy of the structure.

2015-10-03intel_mid_powerbtn: Remove misuse of IRQF_NO_SUSPEND flagSudeep Holla1-2/+8
The IRQF_NO_SUSPEND flag is used to identify the interrupts that should be left enabled so as to allow them to work as expected during the suspend-resume cycle, but doesn't guarantee that it will wake the system from a suspended state, enable_irq_wake is recommended to be used for the wakeup. This patch removes the use of IRQF_NO_SUSPEND flags and uses newly introduce PM wakeup APIs dev_pm_{set,clear}_wake_irq.

2013-01-04Drivers: platform: x86: remove __dev* attributes.Greg Kroah-Hartman1-3/+3
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-03-20intel_mid_powerbtn: use MSIC read/write instead of ipc_scuMichael Demeter1-4/+28
In the 2.6.36 kernel we did not have the MSIC driver. Changed all ipc_scu_reads/writes to use the MSIC driver and defines. Added a fix from the 2.6.36 kernel where the SCU FW could send a power button interrupt to the IA32 FW and the kernel was not running yet. This resulted in the interrupt not getting cleared and the power button was ignored. this fix just clears the interrupt on start-up.
