On this board, only rspi4 is in use. Its bus contains a single device (a wm8978 audio codec). Signed-off-by: Geert Uytterhoeven --- v4: - The platform device basename was changed from "rspi" to "rspi-rz", dropping the platform data flags in the process - Switch to named IRQs v3: - Move platform devices from setup-r7s72100.c to board-genmai.c, as genmai-reference will use devices instantiated from DT - Merge with "ARM: shmobile: genmai: Add RSPI children", as this now touches the same file - Instantiate SPI children in C on genmai only, as genmai-reference will instantiate them from DT v2: - Correct platform device names ("rspi%u.0" -> "rspi.%u") - Add missing platform data - Correct summary (resources -> platform devices) arch/arm/mach-shmobile/board-genmai.c | 42 +++++++++++++++++++++++++++++++++ 1 file changed, 42 insertions(+) diff --git a/arch/arm/mach-shmobile/board-genmai.c b/arch/arm/mach-shmobile/board-genmai.c index a1f6fe1fb06f..0b01b7f7e240 100644 --- a/arch/arm/mach-shmobile/board-genmai.c +++ b/arch/arm/mach-shmobile/board-genmai.c @@ -21,6 +21,8 @@ #include #include #include +#include +#include #include #include #include @@ -41,11 +43,51 @@ static const struct resource ether_resources[] __initconst = { DEFINE_RES_IRQ(gic_iid(359)), }; +/* RSPI */ +#define RSPI_RESOURCE(idx, baseaddr, irq) \ +static const struct resource rspi##idx##_resources[] __initconst = { \ + DEFINE_RES_MEM(baseaddr, 0x24), \ + DEFINE_RES_IRQ_NAMED(irq, "error"), \ + DEFINE_RES_IRQ_NAMED(irq + 1, "rx"), \ + DEFINE_RES_IRQ_NAMED(irq + 2, "tx"), \ +} + +RSPI_RESOURCE(0, 0xe800c800, gic_iid(270)); +RSPI_RESOURCE(1, 0xe800d000, gic_iid(273)); +RSPI_RESOURCE(2, 0xe800d800, gic_iid(276)); +RSPI_RESOURCE(3, 0xe800e000, gic_iid(279)); +RSPI_RESOURCE(4, 0xe800e800, gic_iid(282)); + +static const struct rspi_plat_data rspi_pdata __initconst = { + .num_chipselect = 1, +}; + +#define r7s72100_register_rspi(idx) \ + platform_device_register_resndata(&platform_bus, "rspi-rz", idx, \ + rspi##idx##_resources, \ + ARRAY_SIZE(rspi##idx##_resources), \ + &rspi_pdata, sizeof(rspi_pdata)) + +static const struct spi_board_info spi_info[] __initconst = { + { + .modalias = "wm8978", + .max_speed_hz = 5000000, + .bus_num = 4, + .chip_select = 0, + }, +}; + static void __init genmai_add_standard_devices(void) { r7s72100_clock_init(); r7s72100_add_dt_devices(); + r7s72100_register_rspi(0); + r7s72100_register_rspi(1); + r7s72100_register_rspi(2); + r7s72100_register_rspi(3); + r7s72100_register_rspi(4); + spi_register_board_info(spi_info, ARRAY_SIZE(spi_info)); platform_device_register_resndata(&platform_bus, "r7s72100-ether", -1, ether_resources, ARRAY_SIZE(ether_resources),
