Some periph_rtt implementations do not provide `rtt_set_counter()`. This
adds `periph_rtt_set_counter` as feature to allow testing for its
availability. The feature is provided at CPU level if periph_rtt is
provided by the board for all CPUs implementing `rtt_set_counter()`.
flashpage currently requires pagewise implementation with an optional
extension for per block writes (flashpage_raw). Most implementations
with flashpage_raw implement the pagewise access via the flashpage_raw
functions. This commit makes the flashpage raw the main access method
and adds an extension feature for the pagewise access.
The functions and defines are renamed to reflect this. The API is also
extended with a dedicated function for erasing a sector.
On samd5x only the RTC can wake the CPU from Deep Sleep (pm modes 0 & 1).
The external interrupt controller is disabled, but we can use the tamper
detection of the RTC.
If an gpio interrupt is configured on one of the five tamper detect pins,
those can be used to wake the CPU from Deep Sleep / Hibernate.
The expandable GPIO API requires the comparison of structured GPIO types. This means that inline functions must be used instead of direct comparisons. For the migration process, drivers must first be changed so that they use the inline comparison functions.
This changes the prefixes of the symbols generated from USEMODULE and
USEPKG variables. The changes are as follow:
KCONFIG_MODULE_ => KCONFIG_USEMODULE_
KCONFIG_PKG_ => KCONFIG_USEPKG_
MODULE_ => USEMODULE_
PKG_ => USEPKG_
- Since flash access is shared with CPU2 we resize ROM_LEN
according to CPU2 secure flash memmory area.
- Add assert to prevent unauthorized reads from CPU2 secure
flash area
This commit returns accurate error codes and prevents improper i2c states.
If since i2c_read_reg and i2c_write_reg are full frames the I2C_NOSTOP/START commands should not be supported
- fix reag/write regs function (NOSTART/NOSTOP flags missing)
- use ret variable name instead of err (cosmetic)
- split PERIPH_I2C_NEED_READ/WRITE_REGS to simplify cpu side implementation
