ARM: pxa: add pxa25x device-tree support

2016-08-09T06:16:59+00:00

Add a device-tree machine entry (DT_MACHINE_START) for pxa25x based
platforms.

Take the opportunity to sort the file machine descriptions by

Merge tag 'pxa-for-4.2' of https://github.com/rjarzmik/linux into next/soc

2015-05-15T15:40:15+00:00

Merge "pxa changes for v4.2 cycle" from Robert Jarzmik:

The main and only feature is the conversion of all pxa variants to clock
framework. This encompasses pxa25x, pxa27x and pxa3xx, for all boards.

This should be a disruptive cycle in the normally quiet pxa history, as
the change can break any platform, and the test were performed on only 4
boards (lubbock, zylonite, mioa701, cm-x300).

ARM: pxa: Transition pxa25x, pxa27x, pxa3xx to clk framework

2015-05-12T21:26:46+00:00

Transition the PXA25x, PXA27x and PXA3xx CPUs to the clock framework.
This transition still enables legacy platforms to run without device
tree as before, ie relying on platform data encoded in board specific
files.

This is the last step of clock framework transition for pxa
platforms. It was tested on lubbock (pxa25x), mioa701 (pxa27x) and
zylonite (pxa3xx).

ARM: pxa: Transition pxa25x and pxa27x to clk framework

2015-05-12T21:26:40+00:00

Transition the PXA25x and PXA27x CPUs to the clock framework.
This transition still enables legacy platforms to run without device
tree as before, ie relying on platform data encoded in board specific
files.

The transition breaks the previous clocks activation of pin
control (gpio11 and gpio12). Machine files should be amended to take
that into account.

This is the last step of clock framework transition for pxa25x and
pxa27x, leaving only pxa3xx for further work.

ARM: pxa: pxa_cplds: add lubbock and mainstone IO

2015-04-30T20:52:12+00:00

Historically, this support was in arch/arm/mach-pxa/lubbock.c and
arch/arm/mach-pxa/mainstone.c. When gpio-pxa was moved to drivers/pxa,
it became a driver, and its initialization and probing happened at
postcore initcall. The lubbock code used to install the chained lubbock
interrupt handler at init_irq() time.

The consequence of the gpio-pxa change is that the installed chained irq
handler lubbock_irq_handler() was overwritten in pxa_gpio_probe(_dt)(),
removing :
 - the handler
 - the falling edge detection setting of GPIO0, which revealed the
   interrupt request from the lubbock IO board.

As a fix, move the gpio0 chained handler setup to a place where we have
the guarantee that pxa_gpio_probe() was called before, so that lubbock
handler becomes the true IRQ chained handler of GPIO0, demuxing the
lubbock IO board interrupts.

This patch moves all that handling to a mfd driver. It's only purpose
for the time being is the interrupt handling, but in the future it
should encompass all the motherboard CPLDs handling :
 - leds
 - switches
 - hexleds

The same logic applies to mainstone board.

ARM: pxa: remove pxa95x support

2012-11-15T12:50:13+00:00

PXA95x isn't widely used. And it adds the effort on supporting
multiple platform. So remove it.

The assumption is that nobody will miss this support. If you are
reading this text because you actually require pxa95x support on
a new kernel, we can work out a way to revert this patch or add
support to the mmp platform.
