Merge tag 'pxa-for-4.4' of https://github.com/rjarzmik/linux into next/cleanup
This is the pxa changes for v4.4 cycle. This cycle is bigger than usual : - magician was greatly enhanced (new IPs discovered, ...) - almost all legacy board files have been updated to the new PWM API (mostly for backlight control) - some minor fixes in raumfeld, z2 and mioa701 * tag 'pxa-for-4.4' of https://github.com/rjarzmik/linux: (44 commits) ARM: pxa: remove incorrect __init annotation on pxa27x_set_pwrmode ARM: pxa: raumfeld: make some variables static ARM: pxa: magician: Remove pdata for pasic3-leds ARM: pxa: magician: Add support for PXA27x UDC ARM: pxa: magician: Add support for MAX1587A Vcore regulator ARM: pxa: magician: Change comments to be more informative ARM: pxa: magician: Move platform_add_devices() to the end of magician_init() ARM: pxa: magician: Add missing regulator for PWM backlight ARM: pxa: magician: Add debug message for backlight brightness function ARM: pxa: magician: Remove definition of the STUART port ARM: pxa: magician: Fix wrongly enabled USB host ports ARM: pxa: magician: Fix support for Intel Strata NOR Flash ARM: pxa: magician: Fix redundant GPIO request for pxaficp_ir ARM: pxa: magician: Fix platform data for both PXA27x I2C controllers ARM: pxa: magician: Fix and add charging detection functions ARM: pxa: magician: Optimize Samsung LCD refresh to 50Hz ARM: pxa: magician: Rename charger cable detection EGPIOs ARM: pxa: magician: Optimize powerup delays for Samsung LCD ARM: pxa: magician: Rename abstract LCD GPIOs ARM: pxa: magician: Add new discovered EGPIO pins ...
