Deleted lines that caused the problem. Note that, in nrf_drv_pwm_init there are lines that check if pwm instance is already running, so we don't even need to check it in nordic_pwm_init.
nrf_drv_uninit should be used in nordic_pwm_restart.
i2c_api implementation for NRF52 does a disable() followed by uninit().
The uniinit() implementation in NRF drivers layer makes another call to
disable. This throws off the state of the I2C instance leading to an
assert. Since the disable is only invoked from the I2C API layer for
Nordic, remove this redundant call.

The ITM must be initialized before the SoftDevice, but due to the
lazy initialization in C++ on (at least) GCC the ITM init call
might happen too late.
This commit moves the initialization code into the NRF52 system
startup file.
* Elevate RTC2 interrupt priority to same level as UARTE to prevent
race condition on shared variables.
* Remove unused TXDRDY event code.
* Fix typo in macro.
It has been noticed that there is a problem with us ticker on NRF_52840 board after 32 bit counter has been used for us ticker on NRF52 family boards.
Currently NRF52 symbol is defined only for MCU_NRF52832 (not for MCU_NRF52840) and based on this symbol 16 or 32 bit counter is selected (16 bit for NRF51 family and 32 for NRF52 family).
Since MCU_NRF52840 defines NRF52840_XXAA and provides 32 bit counters, 32 bit counter should be selected also when NRF52840_XXAA symbol is defined.
New changes to Mbed error reporting in 5.9 exposed bug in SPI
driver where an instance was uninitialized twice which triggered
an ASSERT.
This fix keeps track of which instance has been initialized and
only calls uninit when it is safe.
Set the second highest user level, leaving the highest for UART (we are having constant overflows) and two levels below for everything else.
This should increase the timer accuracy.
RTC counter is 24-bit. Upper layer handles counter size and wraps ticks count when interrupt is to be fired before passing it to common_rtc_set_interrupt(), but for consistency and safety reasons we can wrap it again in the NRF driver.
The nrf section features has different implementations for each compilers supported by mbed-os. The header guard was ruling out compiler other than GCC by checking if __GNUC__ is defined. This check is not applicable on mbed os as the ARM compiler compile sources with gnu compatibility.
This patch makes sure that the right implementation is selected for the right compiler . The previous patch has been reverted as it is not reliable.
