devicetree.h: add accessor API for nodes and properties This is joint work with Kumar Gala (see signed-off-by). Add helper macros which abstract the "true names" of each of the four types of node identifier we intend to support (e.g. DT_ALIAS(), DT_INST()). These can be passed to a new DT_PROP() macro which can be used to read the value of a devicetree property given a node identifier from one of these four other macros, and the as-a-c-token name of the property. Add other accessor macros and tests as well. Add some convenience APIs for writing device drivers based on instance numbers as well. Drivers can "#define DT_DRV_COMPAT driver_compatible" at the top of the file, then utilize these DT_INST_* macros to access various property defines. For example, the uart_sifive driver can do: #define DT_DRV_COMPAT sifive_uart0 Then use DT_INST macros like: .port = DT_INST_REG_ADDR(0), .sys_clk_freq = DT_INST_PROP(0, clock_frequency), For convenience working with specific hardware, also add: <devicetree/gpio.h> <devicetree/adc.h> <devicetree/spi.h> Signed-off-by: Martí Bolívar <marti.bolivar@nordicsemi.no> Signed-off-by: Kumar Gala <kumar.gala@linaro.org> 2020-02-27 12:49:59 +08:00			`# Copyright (c) 2020 Nordic Semiconductor ASA`
