I noticed that when it landed in today's linux-next (ie, next-20141201) as commit 4403ac46edcd ("ARM: at91: remove at91sam9263 legacy board support"). > arch/arm/configs/at91sam9263_defconfig | 151 --- > arch/arm/mach-at91/Kconfig.non_dt | 21 - > arch/arm/mach-at91/Makefile | 4 - > arch/arm/mach-at91/at91sam9263.c | 399 -------- > arch/arm/mach-at91/at91sam9263_devices.c | 1538 ------------------------------ > arch/arm/mach-at91/board-sam9263ek.c | 493 ---------- > 6 files changed, 2606 deletions(-) > delete mode 100644 arch/arm/configs/at91sam9263_defconfig > delete mode 100644 arch/arm/mach-at91/at91sam9263_devices.c > delete mode 100644 arch/arm/mach-at91/board-sam9263ek.c > >[...] > diff --git a/arch/arm/mach-at91/at91sam9263_devices.c b/arch/arm/mach-at91/at91sam9263_devices.c > deleted file mode 100644 > index cef0e2f57068..000000000000 > --- a/arch/arm/mach-at91/at91sam9263_devices.c > +++ /dev/null >[...] > -/* -------------------------------------------------------------------- > - * RTT > - * -------------------------------------------------------------------- */ > - > -static struct resource rtt0_resources[] = { > - { > - .start = AT91SAM9263_BASE_RTT0, > - .end = AT91SAM9263_BASE_RTT0 + SZ_16 - 1, > - .flags = IORESOURCE_MEM, > - }, { > - .flags = IORESOURCE_MEM, > - }, { > - .flags = IORESOURCE_IRQ, > - } > -}; > - > -static struct platform_device at91sam9263_rtt0_device = { > - .name = "at91_rtt", > - .id = 0, > - .resource = rtt0_resources, > -}; > - > -static struct resource rtt1_resources[] = { > - { > - .start = AT91SAM9263_BASE_RTT1, > - .end = AT91SAM9263_BASE_RTT1 + SZ_16 - 1, > - .flags = IORESOURCE_MEM, > - }, { > - .flags = IORESOURCE_MEM, > - }, { > - .flags = IORESOURCE_IRQ, > - } > -}; > - > -static struct platform_device at91sam9263_rtt1_device = { > - .name = "at91_rtt", > - .id = 1, > - .resource = rtt1_resources, > -}; > - > -#if IS_ENABLED(CONFIG_RTC_DRV_AT91SAM9) > -static void __init at91_add_device_rtt_rtc(void) > -{ > - struct platform_device *pdev; > - struct resource *r; > - > - switch (CONFIG_RTC_DRV_AT91SAM9_RTT) { This and... > - case 0: > - /* > - * The second resource is needed only for the chosen RTT: > - * GPBR will serve as the storage for RTC time offset > - */ > - at91sam9263_rtt0_device.num_resources = 3; > - at91sam9263_rtt1_device.num_resources = 1; > - pdev = &at91sam9263_rtt0_device; > - r = rtt0_resources; > - break; > - case 1: > - at91sam9263_rtt0_device.num_resources = 1; > - at91sam9263_rtt1_device.num_resources = 3; > - pdev = &at91sam9263_rtt1_device; > - r = rtt1_resources; > - break; > - default: > - pr_err("at91sam9263: only supports 2 RTT (%d)\n", > - CONFIG_RTC_DRV_AT91SAM9_RTT); this are the only places were the Kconfig symbol RTC_DRV_AT91SAM9_RTT was used. It is useless now. That matches its help text, that reads: This option is only relevant for legacy board support and won't be used when booting a DT board. > - return; > - } > - > - pdev->name = "rtc-at91sam9"; > - r[1].start = AT91SAM9263_BASE_GPBR + 4 * CONFIG_RTC_DRV_AT91SAM9_GPBR; > - r[1].end = r[1].start + 3; > - r[2].start = NR_IRQS_LEGACY + AT91_ID_SYS; > - r[2].end = NR_IRQS_LEGACY + AT91_ID_SYS; > -} > -#else > -static void __init at91_add_device_rtt_rtc(void) > -{ > - /* Only one resource is needed: RTT not used as RTC */ > - at91sam9263_rtt0_device.num_resources = 1; > - at91sam9263_rtt1_device.num_resources = 1; > -} > -#endif > - > -static void __init at91_add_device_rtt(void) > -{ > - at91_add_device_rtt_rtc(); > - platform_device_register(&at91sam9263_rtt0_device); > - platform_device_register(&at91sam9263_rtt1_device); > -} Is a patch to remove that symbol from drivers/rtc/Kconfig queued somewhere?
