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