Merge tag 'pxa-for-4.4' of https://github.com/rjarzmik/linux into next/cleanup

2015-10-23T17:15:03+00:00

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

ARM: pxa: remove incorrect __init annotation on pxa27x_set_pwrmode

2015-10-16T18:52:39+00:00

The z2 machine calls pxa27x_set_pwrmode() in order to power off
the machine, but this function gets discarded early at boot because
it is marked __init, as pointed out by kbuild:

WARNING: vmlinux.o(.text+0x145c4): Section mismatch in reference from the function z2_power_off() to the function .init.text:pxa27x_set_pwrmode()
The function z2_power_off() references
the function __init pxa27x_set_pwrmode().
This is often because z2_power_off lacks a __init
annotation or the annotation of pxa27x_set_pwrmode is wrong.

This removes the __init section modifier to fix rebooting and the
build error.

ARM: pxa: magician: Rename charger cable detection EGPIOs

2015-10-14T21:06:55+00:00

This patch renames EGPIOs, which are used for the charging cable presence
and type detection. Old names did not correspond with an observed
functionality (on board_id 0x3a). The behavior is not:

- AC charger
- USB charger
- Cable detection

, but:

- AC/USB type
- Cable detection1
- Cable detection2

This patch fixes a possible typo in the bit offset for the cable detection
EGPIO declaration, too.

ARM: pxa: magician: Rename abstract LCD GPIOs

2015-10-14T21:06:54+00:00

This patch renames GPIOs, which are used to control the power lines to
the LCD screen. New names correspond to a real functionality, which was
measured on the HTC Magician board_id 0x3a.

ARM: pxa: magician: Add new discovered EGPIO pins

This patch adds EGPIO pins: Infra transceiver power, NiCD charging and
inserted charger cable.

ARM: pxa: fix DFI bus lockups on startup

2015-09-13T10:55:27+00:00

After the conversion of pxa architecture to common clock framework, the
NAND clock can be disabled on startup if no nand driver claims it.

In this case, it happens that if the bootloader used the NAND and set
the DFI arbitration bit, the next access to a static memory controller
area, such as an ethernet card, the system bus will stall, and the core
will be stalled forever.

Fix this by clearing the DFI arbritration bit in pxa3xx startup. The bit
will be enabled the pxa3xx-nand driver on need anyway. The only left
requirement is that upon pxa3xx-nand removal, the bit should be cleared
before the clock is disabled.

ARM: pxa: lubbock: use new pxa_cplds driver

2015-04-30T20:52:51+00:00

As the interrupt handling was transferred to the pxa_cplds driver,
make the switch in lubbock platform code.

ARM: pxa: fix broken isa interrupts for zeus and viper

2015-01-27T22:53:07+00:00

Commit "ARM: pxa: arbitrarily set first interrupt number" broke viper
and zeus boards which still refer to PXA_ISA_IRQ() macro. Redefine
the macro, which declares the legacy interrupts from 0 to 15.
