2017-01-30pwm: lpss: Add Intel Gemini Lake PCI IDMika Westerberg1-0/+1
Intel Gemini Lake PWM is pretty much same as used in Intel Broxton. Add this new PCI ID to the list of supported devices. Signed-off-by: Mika Westerberg <[email protected]> Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Thierry Reding <[email protected]>
2017-01-30pwm: lpss: Do not export board infos for different PWM typesAndy Shevchenko1-0/+21
The PWM LPSS probe drivers just pass a pointer to the exported board info structures to pwm_lpss_probe() based on device PCI or ACPI ID. In order to remove the knowledge of specific devices from library part of the driver and reduce noise in exported namespace just duplicate the board info structures and stop exporting them.

2016-07-11pwm: lpss: pci: Enable PWM module on Intel EdisonAndy Shevchenko1-0/+1
Intel Edison has 4 PWM channels on the die with the same IP as in Broxton. Enable it. Signed-off-by: Andy Shevchenko <[email protected]> Signed-off-by: Thierry Reding <[email protected]>
2015-11-06pwm: lpss: Add support for runtime PMQipeng Zha1-0/+32
To be able to save some power when PWM is not in use, add support for runtime PM for this driver. This also allows the platform to transition to low power S0ix states when the system is idle.

2015-11-06pwm: lpss: Add more Intel Broxton IDsMika Westerberg1-0/+1
Add more Intel Broxton ACPI and PCI IDs to the driver supported devices list. Signed-off-by: Mika Westerberg <[email protected]> Signed-off-by: Thierry Reding <[email protected]>
2015-11-06pwm: lpss: Support all four PWMs on Intel BroxtonMika Westerberg1-2/+2
Intel Broxton has similar PWM than Intel Braswell but instead of one it has four PWMs included in one PCI/ACPI device. This patch adds support for all the four PWMs and changes the PCI part of the driver to use 'pwm_lpss_bxt_info' instead.

2014-08-23pwm: lpss: pci: Move to use pcim_enable_device()Andy Shevchenko1-2/+1
Let's use managed functions for this driver. Signed-off-by: Andy Shevchenko <[email protected]> Reviewed-by: Mika Westerberg <[email protected]> Signed-off-by: Thierry Reding <[email protected]>
2014-08-23pwm: lpss: Properly split driver to partsAndy Shevchenko1-0/+65
The driver consists of core, PCI, and platform parts. It would be better to split them into separate files. The platform driver is now called pwm-lpss-platform. Thus, previously set CONFIG_PWM_LPSS=m is not enough to build it. But we are on the safe side since it seems no one from outside Intel is using it for now. While here, move to use macros module_pci_driver() and module_platform_driver().
