dts: arm: ti: Remove use of CONFIG_SOC_* from TI SoC dts files To move forward and remove use of Kconfig in dts files lets just create SoC specific dtsi files that the boards can include. This lets us remove: CONFIG_SOC_CC3220SF CONFIG_SOC_MSP432P401R Signed-off-by: Kumar Gala <kumar.gala@linaro.org> 2018-09-12 23:14:14 +08:00			`/*`

dts: introduce macro's to help with changing unit-addr Since there are times that we include a base .dtsi file and change the reg address we tend to end up with warnings that the reg address and unit-address don't match. To handle this introduce a simple DT_ADDR(x) macro that will prepend '0x' to a 'unit-address' style address. #define DCCM_ADDR 80000000 /* in unit-address format */ dccm0: dccm@DCCM_ADDR { reg = <DT_ADDR(DCCM_ADDR) 0x1>; ... }; This allows the dts file to override the value of DCCM_ADDR and than to have the unit-address of the node and the reg address match.
