* ARM: pxa: Move UNCACHED_PHYS_0 mapping from generic.c to pxa2[57]x.cLaurent Pinchart2014-07-121-0/+5
| | | | | | | | | | The UNCACHED_PHYS_0 mapping is only needed on PXA25x and PXA27x platforms. Move it to pxa25x.c and pxa27x.c to avoid wasting vmalloc space on PXA3xx.

Registration of pxa_gpio_syscore_ops is moved into pxa-gpio driver, but it still exists in arch-pxa directory. It resulsts failure on reboot and suspend. Now remove the registration code in arch-pxa.

* ARM: pxa: add dummy clock for pxa25x and pxa27xHaojian Zhuang2012-03-061-0/+1
| | | | | | | | | | | | | | gpio-pxa driver is shared among arch-pxa and arch-mmp. Clock is the essential component on pxa3xx/pxa95x and arch-mmp. So we need to define dummy clock in pxa25x/pxa27x instead. This regression was introduced by the commit "ARM: pxa: add dummy clock for sa1100-rtc", id a55b5adaf403c4d032e0871ad4ee3367782f4db6.

* [ARM] pxa: allow platforms to control which uarts are registeredRussell King2009-12-011-6/+1
| | | | | | | | | | | | | | | | | | For some platforms, it is inappropriate to register all PXA UARTs. In some cases, the UARTs may not be used, and in others we may want to avoid registering the UARTs to allow other drivers (eg, FICP) to make use of the UART. In addition, a while back there was a request to be able to pass platform data to the UART driver. This patch enables all of this by providing functions platforms can call to register each individual UART.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Original patch from Marek Vasut, the problems with PXA26x are: 1. there are additional 4 GPIOs 86,87,88,89 have their direction bits inverted in GPDR2, as well as their alternate function bits being '1' for their GPIO functionality in GAFRx 2. there is no easy way to decide if the processor is a pxa26x or a pxa250/pxa255 at run-time, so the assumption here is the pxa26x will be treated as one of the pxa25x variants, and board code should have a better knowledge of the processor it is featured Introduce pxa26x_init_irq() for the second purpose, and treat the additional GPIOs > 85 on PXA25x specially. Kconfig option CONFIG_CPU_PXA26x is introduced to optimize the code a bit when PXA26x support isn't needed. Board config options have to select this to enable the support for PXA26x. __gpio_is_inverted() will be optimized way when CONFIG_CPU_PXA26x isn't selected.
