* ARM: PXA: move HAVE_CLK selectLucas Stach2016-01-191-0/+1
| | | | | | | | | | | | Claiming that all of PXA has CLK implemented, while only PXA3XX selects the relevant clock implementations causes lots of build failures for the other PXA architectures. Fix it by moving the HAVE_CLK select to the one PXA arch, that actually has it. Signed-off-by: Lucas Stach <l.stach@pengutronix.de> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * restart: replace reset_cpu with registered restart handlersSascha Hauer2015-08-271-2/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This replaces the reset_cpu() function which every SoC or board must provide with registered handlers. This makes it possible to have multiple reset functions for boards which have multiple ways to reset the machine. Also boards which have no way at all to reset the machine no longer have to provide a dummy reset_cpu() function. The problem this solves is that some machines have external PMICs or similar to reset the system which have to be preferred over the internal SoC reset, because the PMIC can reset not only the SoC but also the external devices. To pick the right way to reset a machine each handler has a priority. The default priority is 100 and all currently existing restart handlers are registered with this priority. of_get_restart_priority() allows to retrieve the priority from the device tree which makes it possible for boards to give certain restart handlers a higher priority in order to use this one instead of the default one.

* | gpio: Drop asm-generic/gpio.hSascha Hauer2015-08-201-1/+0
| | | | | | | | | | | | | | | | | | | | Since we no longer have custom gpio function prototypes we can drop the prototypes from asm-generic/gpio.h can add them to include/gpio.h instead. While at it add static inline dummy wrappers for !CONFIG_GENERIC_GPIO so that code using gpios can compile without gpio support. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* | ARM: PXA: use generic gpio prototypesSascha Hauer2015-08-073-32/+33
|/ | | | | | | | | PXA is the only architecture that uses its own prototypes for the gpio functions because it uses static inline variants of these functions. For the sake of streamlining with other architectures move them to a C file and use the generic gpio prototypes. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | | | | | Add the first pxa3xx board, zylonite. Zylonite is the Marvell System Development Platform. Several version are available, based on either : - PXA300 - PXA310 - PXA320 This version was only tested on a PXA310 based board, and uses : - the ethernet controller - the nand controller These drivers seem to be common to all zylonite boards.

| | | | | | | | | | | | | | | Add the pxa3xx architecture, for pxa300, pxa310 and pxa320 SoCs. This includes : - the registers - the cpu type - the reset source handling - a minimal set of clocks - pin control definitions In this last case, the big mfp-pxaxxx.h files were dropped, forcing board developers to use MFP_LPM_* macros cunningly.

* ARM: pxa: add poweroff capabilityRobert Jarzmik2014-01-204-0/+99
| | | | | | | | | | | Add the capability for the PXA architecture to poweroff. As there is no true poweroff, ie. the power regulator is not available for shut off from the core, the poweroff puts the SoC into a deep sleep mode (mode 7), where almost no current is sunk.

* Set model and hostname at boardlevelSascha Hauer2013-08-161-5/+0
| | | | | | | | | | | | With multiboard support the compiletime generated BOARDINFO string gets more and more meaningless. This removes it from Kconfig and replaces it with a variable that can be set at boardlevel. Also many boards have a standard setting for the hostname in the environment. This patch also moves the standard to C code by calling barebox_set_hostname(). Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| | | | | | | | | | | | | | | As pxafb can rely on a PWM to control backlight, and because driver dependencies are hard to deal with, remove automatic enable of PXAFB on probe. The user should in its environment do a : - fb0.enable=1 This way, the PWM has been probed and is ready to work, and the pxafb backlight control works.
