ARM: davinci: uart: move to devid based clk_get For modules having single clock, clk_get should be done with dev_id. But current davinci implementation handles multiple instances of the UART devices with single platform_device_register. Hence clk_get is based on con_id rather than dev_id, this is not correct. Do platform_device_register for each instance and clk_get on dev_id.

ARM: davinci: da850: Add ti-aemif lookup for clock matching The davinci boards don't have their clocks in DT yet and getting a clock will fail, unless registering them as clk_lookups. This registers the aemif clock for the ti-aemif memory driver. The current aemif lookup entry resolving to the same clock: 'CLK(NULL, "aemif", &aemif_clk)' is currently used by davinci_nand and remains for non-DT and backward compatibility. Currently the davinci boards only configure the AEMIF in case of non-DT boot, via some code in mach-davinci. This change will allow DT-based davinci platforms to do the same, via the ti-aemif memory driver code.

ARM: dts: da850: Add basic DTS for the LCDK The LCDK is the successor to the late Hawkboard. Among the differences are the flash (16bits vs 8bits) and some pins (MMC, LEDs, buttons, some external connectors), however the main components remain the same (eth. phy, audio codec, video decoder and DAC) except for the main PMIC, different and hard-wired on the LCDK (the LDOs and DCDCs are always on). A DT-only boot with this addition gives functional UART, reboot via watchdog, RTC, ethernet and MMC (I added the CD GPIO for the MMC although davinci_mmc doesn't call the OF facilities of mmc core).

ARM: delete struct sys_timer Now that the only field in struct sys_timer is .init, delete the struct, and replace the machine descriptor .timer field with the initialization function itself. This will enable moving timer drivers into drivers/clocksource without having to place a public prototype of each struct sys_timer object into include/linux; the intent is to create a single of_clocksource_init() function that determines which timer driver to initialize by scanning the device dtree, much like the proposed irqchip_init() at: http://www.spinics.net/lists/arm-kernel/msg203686.html Includes mach-omap2 fixes from Igor Grinberg.
