wes3 opened a new pull request #2024: hw/mcu/dialog: Add helper to enable/disable AMBA clocks
URL: https://github.com/apache/mynewt-core/pull/2024
Add a helper to enable/disable AMBA clocks in CRG_TOP->CLK_AMBA_REG.
The code was doing an un-protected read-modify-write and if the clock is modified inside ISR's this could cause unpredictable behavior.
The helper will enable/disable interrupts around the setting/clearing of bits in that register. The helpers added are:
da1469x_clock_amba_enable(mask)
da1469x_clock_amba_disable(mask)
