* | ARM: 6153/1: nomadik MTU to use dynamic shift and mult assignmentLinus Walleij2010-06-16
| | | | | | | | | | | | | | | | | | | | | | | | This removes the hard-coded shift values for the MTU timer, since the different platforms using this has very different running frequencies doing this dynamically is a better idea. Also take this opportunity to make a more through shutdown of the MTU clockevent when requested.

* | ARM: 5972/1: nomadik-gpio: convert to platform driverRabin Vincent2010-03-19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | On the U8500 platform there are four GPIO blocks, each with a 4K address space, including the peripheral identification. However, each of these blocks have a varying number of banks, each of which have 32 GPIOs and an interrupt line. The current nomadik-gpio driver implementation can handle each of these sub-banks easily with one instance each, but cannot as-is be hooked up to them because it is an AMBA driver and it expects to see a peripheral with the appropriate peripheral ids but having only one bank and only one interrupt. Solve this by converting the driver to a platform driver.

* | ARM: 5969/1: nomadik: move gpio to plat-nomadikRabin Vincent2010-03-19
|/ | | | | | | | | | | | | | Move the Nomadik GPIO driver to plat-nomadik so that it can also be used on the Ux500 platform. The mach-nomadik include/mach/gpio.h is replaced by one that includes the one now in plat-nomadik, so that code doesn't need to include the one in plat specifically, and can instead use <linux/gpio.h> as usual.

* ARM: 5786/1: Introduce plat-nomadik, MTU code re-organizationSrinidhi Kasagar2009-11-28
Introduce the plat-nomadik folder for ST-Ericsson machines including the existing nomadik 8815 architecture. This also moves the existing MTU (MultiTimerUnit) of nomadik 8815 to the proposed plat-nomadik and adds HAS_MTU.
