pwm: lpss: Properly split driver to parts 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().

pwm: lpss: Include headers we are the direct user of For the sake of integrity, include headers we are the direct user of. Replace the inclusion of device.h by a forward declaration of struct device plus a (cheaper) of types.h as device.h is an expensive include (measured in compiler effort).

pwm: lpss: Rename MAX_PWMS --> LPSS_MAX_PWMS The MAX_PWMS definition is already being used by the PWM core. Using the same name in the certain driver confuses people and potentially can clash with it. Hence, rename it by adding LPSS prefix.

pwm: lpss: Move struct pwm_lpss_chip definition to the header file Move struct pwm_lpss_chip definition from pwm-lpss.c to pwm-lpss.h, so that the pci/platform drivers can access the info member (struct pwm_lpss_boardinfo *). This is a preparation patch for adding platform specific quirks, which the drivers need access to, to pwm_lpss_boardinfo.

pwm: lpss: Deduplicate board info data structures Move the board info structures from the glue drivers to the common library and hence deduplicate configuration data. For the Intel Braswell case the ACPI version should be used. Because switch to ACPI/PCI is done in BIOS while quite likely the rest of AML code is the same, meaning similar issue might be observed. There is no bug report due to no PCI enabled device in the wild, Andy thinks, and only reference boards can be tested, so nobody really cares about Intel Braswell PCI case.
