Andrzej Głąbek	20202902f2	dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig These changes were obtained by running a script created by Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following specification: 1. Read the contents of all dts_fixup.h files in Zephyr 2. Check the left-hand side of the #define macros (i.e. the X in #define X Y) 3. Check if that name is also the name of a Kconfig option 3.a If it is, then do nothing 3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it has neither of these two prefixes 4. Replace the use of the changed #define in the code itself (.c, .h, .ld) Additionally, some tweaks had to be added to this script to catch some of the macros used in the code in a parameterized form, e.g.: - CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS - CONFIG_UART_##idx##_TX_PIN - I2C_SBCON_##_num##_BASE_ADDR and to prevent adding DT_ prefix to the following symbols: - FLASH_START - FLASH_SIZE - SRAM_START - SRAM_SIZE - _ROM_ADDR - _ROM_SIZE - _RAM_ADDR - _RAM_SIZE which are surprisingly also defined in some dts_fixup.h files. Finally, some manual corrections had to be done as well: - name##_IRQ -> DT_##name##_IRQ in uart_stm32.c Signed-off-by: Andrzej Głąbek <andrzej.glabek@nordicsemi.no>	7 years ago

dts_fixups: Use DT_ prefix in all defined labels not related to Kconfig

These changes were obtained by running a script  created by
Ulf Magnusson <Ulf.Magnusson@nordicsemi.no> for the following
specification:

1. Read the contents of all dts_fixup.h files in Zephyr
2. Check the left-hand side of the #define macros (i.e. the X in
   #define X Y)
3. Check if that name is also the name of a Kconfig option
   3.a If it is, then do nothing
   3.b If it is not, then replace CONFIG_ with DT_ or add DT_ if it
       has neither of these two prefixes
4. Replace the use of the changed #define in the code itself
   (.c, .h, .ld)

Additionally, some tweaks had to be added to this script to catch some
of the macros used in the code in a parameterized form, e.g.:
- CONFIG_GPIO_STM32_GPIO##__SUFFIX##_BASE_ADDRESS
- CONFIG_UART_##idx##_TX_PIN
- I2C_SBCON_##_num##_BASE_ADDR
and to prevent adding DT_ prefix to the following symbols:
- FLASH_START
- FLASH_SIZE
- SRAM_START
- SRAM_SIZE
- _ROM_ADDR
- _ROM_SIZE
- _RAM_ADDR
- _RAM_SIZE
which are surprisingly also defined in some dts_fixup.h files.

Finally, some manual corrections had to be done as well:
- name##_IRQ -> DT_##name##_IRQ in uart_stm32.c

ext: mcux: Reorganize imported drivers into soc family subfolders

We have been combining imported mcux drivers into a flattened directory
structure to maximize driver reuse, but the introduction of additional
nxp soc families (lpc and imx) to zephyr has introduced driver naming
conflicts. This caused us to rename and modify imported files, such as
fsl_gpio.c/h, to make them unique across all three nxp soc families.
This makes updating the the mcux drivers complicated, especially for the
lpc family.

Reoganize the mcux drivers into soc family subfolders, so we can just
copy all the drivers from an mcux distribution (which is done on an
soc-basis) into the appropriate soc family folder. Undo all of the
naming changes that occurred when lpc and imx drivers were originally
imported. Undo the accidental squashing of the kinetis watchdog and dcdc
drivers that occurred when the imx drivers were introduced.

The drawback to this approach is that we have duplicate files when the
same hw ip modules exist in multiple soc families, however there are
only few cases where this occurs, such as fsl_lpuart and fsl_trng.
