boards: add stub drivers folder for later use

* boards: add stub drivers folder for later use

    The board/drivers folder is added for future use.

    In this folder we should place drives that are platform specific and
    depend on HW that is present only on a specific platform.

    NOTE: All shared drivers should go to the regular driver folder

* tools: shift BOARD_DIR one level up

    In preparation for drivers and common folders we are moving the
    BOARD_DIR path up one level.

    Signed-off-by: Alin Jerpelea <alin.jerpelea@sony.com>

* tools: add drivers/platform symlink

    Link the boards/<arch>/<chip>/drivers dir to drivers/platform

    Signed-off-by: Alin Jerpelea <alin.jerpelea@sony.com>

* drivers: add platform specifc drivers extension

    There are platforms that use specific drivers and we should be able to
    include those drivers in the build

* board: cxd56xx: drivers: add AK09912 driver for SCU

    This is a platform specific driver connected on the SCU unit.

Squashed commit of the following:

    boards/arm/s32k1xx/s32k148evb:  Correct linker scripts for the S32K148, Update README files, Hook eht S32K148EVB into the configuration and build system.

    arm/s32k1xx/s32k148evb:  Verify core and peripheral clocking.  It is the same as the S32K146EVB.  Fixed one-too-many copy-paste error in both.

    boards/arm/s32k1xx/s32k148evb:  Correct LED and button pin number for the S32K148EVB.

    boards/arm/s32k1xx/s32k148evb:  Change all occurrences of 146 to 148.

    boards/arm/s32k1xx/s32k148evb:  Initial S32K148EVB.  Initial commit is just  clone of S32K146EVB with file name changes

c6026d7500 With these changes the S32K146EVB minimal NSH is function. Only verifed while running from SRAM.
arch/arm/src/s32k1xx/s32k1xx_lowputc.c:  Fix a typo that prevented LPUART1 from working.
    arch/arm/src/s32k1xx/s32k1xx_periphclocks.c and related files:  Fix yet another case of confusion between pre-decremented and non-decremented divider values.  Enforce the rule that dividers are not decremented until the moment they are written into registers.
    arch/arm/src/s32k1xx/s32k1xx_clockconfig.c:  Fix another problem related to whether a divider is pre-decremented or not.  The answer must be the divder values are never pre-decremented.  They are decremented just before being written to hardware.
    arch/arm/src/s32k1xx/s32k1xx_clockconfig.c:  Clean up some bad conditional logic.  Precedence of operators problem.
    boards/arm/s32k1xx/s32k118evb:  Add support for execution out of SRAM.  This is helpful for bringup when you want to avoid putting a lethal image in FLASH.
    arch/arm/src/s32k1xx/s32k1xx_clockconfig.h:  Remove crystal frequency, it is not used.
    arch/arm/src/s32k1xx/s32k1xx_wdog.h:  Fix a typo in a register name.i
    boards/arm/s32k1xx/s32k*evb/configs/nsh/defconfig:  Create Motorola SREC output format.

df1294906d arch/arm/src/s32k1xx/s32k1xx_clockconfig.c and related files: Fix confusion about who decrements the rster value. Some dividers may have a function range of 1..8 but the register value is 0..7. There were several places where values were getting decremented twice: Once by higher up logic and once by the register access logic. A such dividers were reviewed and, hopefully, all were fixed. 2019-08-19 13:07:45 -06:00

c3f16a46f0 This commit brings the S32K118EVB board to code complete and ready for testing. This commit adds some minor initialization fixes (like disabling the WDOG, enabling the I-cache, and initializing the MPU. It brings more files in from the Kinetis port for the IDLE loop and for GPIO functionality. This also address register definition header file for LMEM and MPU. 2019-08-18 17:26:10 -06:00

db0641556e boards/arm/s32k1xx/s32k118evb: Implement board support for LEDs and buttons. This is taken from the Freedom-K66f with has the same LED and button configuation as the S32K116EVB and uses the same GPIO IP.
boards/arm/s32k1xx/s32k118evb/include/board.h:  Add LPUART0 pin disambiguation.

arch/arm/src/s32k1xx/hardware:  Add pin mux definitions for S32K116, 118, 142, 144, 146, and 148.

arch/arm/src/s32k1xx/s32k1xx_pin.c and .h:  Add support for PIDR register that disables a gneral purpose pin from acting as an input.

arch/arm/src/s32k1xx/s32k1xx_pin.c and .h:  The device does not support slew rate controls or open drain (on all the pins).  Only pins that are configured for a protocol that requires open-drain (e.g;, LPI2C, LPUART single-wire) will work in open-drain mode.

8987a9e374 This commit adds initial board support for the NXP S32K118EVB. This configuration is intended, initially, to support development of the architecture support. This is VERY much a work in progress and you should not use this configuration unless you are interested in assisting with the bring-up.
