[PATCH v2 0/9] [New BSP] Add initial support for Freescale Kinetis TWR-K70F120M development kit

[Paul Osmialowski <pawelo@xxxxxxxxxxx>]

This is the second iteration of the patchset that adds a basic initial
support to TWR-K70F120M development kit which is based on ARM Cortex-M4
Freescale Kinetis K70 SoC.

Previous iteration met with a broad response for which I would like
to thank everyone involved.

Following is the change list:

1. First three ('controversial') patches are removed.

   As long as it doesn't hit platform stability, I don't use these Cortex-M
   compiler flags, it should not stop the whole of the patchset.

   The idle quirks issue is now addressed by adding idle.c which provides
   callback for arm_pm_idle.

   The infamous zlib patch was not needed at all - I didn't really check
   what it was protecting against.

2. include/mach/idle.h file removed.

3. kinetis_platform.c renamed to kinetis.c, obj-$(CONFIG_MACH_KINETIS)
   changed to obj-y, CONFIG_MACH_KINETIS not needed anymore, removed with
   the whole of the Kconfig file in mach-kinetis directory.

4. Assuming that fsl-edma and fsl-lpuart drivers handle big-endian properly,
   pinctrl, clk and timer drivers now support big-endian the same way
   ("big-endian" option in .dts).

5. All addresses based on KINETIS_AIPS0PERIPH_BASE and
   KINETIS_AIPS1PERIPH_BASE are moved to DT. The struct kinetis_sim_regs
   is moved to clk-kinetis.c. As a result whole include/mach/kinetis.h is
   now removed.

6. Removed kinetis_map_io() from kinetis.c (formerly kinetis_platform.c).

7. Removed kinetis_init() function along with a call to
   of_platform_populate().

8. Removed MACH_KINETIS from arch/arm/tools/mach-types, removed inclusion
   of asm/mach-types.h in kinetis.c (formerly kinetis_platform.c).

9. Removed inclusion of linux/clk.h from clk-kinetis.c.

10. Clock and timer drivers are in separate patches now.

11. '&& ARM' removed from drivers/clocksource/Kconfig.

12. s/clk/evt/ in timer-kinetis.c (actually, the affected *_set_mode()
    function is replaced by a set of *_set_state_*() functions).

13. Removed pointless raw_local_irq_save/restore() from timer-kinetis.c.

14. Removed overhead () from each of the &(.....) from timer-kinetis.c.

15. Removed unused KINETIS_PITn_IRQ definitions from timer-kinetis.c.

16. Replaced use of IRQ actions with request_irq() in timer-kinetis.c.

17. Removed all uses of KINETIS_MKCG() macro and whole include/mach/power.h
    - now all clock gate details are specified directly in the DT.
    For each clock gate #clock-cells = <2> where the first part of the gate
    address is zero-based gate register number, the second part is the bit
    index.

18. Shortened long timer names in timer-kinetis.c.

19. Ensured module friendliness of pinctrl driver (tristate
    CONFIG_PINCTRL_KINETIS)

20. Removed txirq_names[] array from fsl-edma.c - sprinft()-generated
    strings used instead.

21. fsl-lpuart and fsl-edma related patches are both split into two:
    1) changes in the driver and 2) use in platform.

22. Removed all occurences of CONFIG_ARCH_KINETIS from fsl-edma.c - now it
    looks more like fsl-lpuart driver (boolean 'kinetis' field in the main
    driver structure).
