2007-05-08aty128fb: fix blankingWitold Filipczyk
I have a problem with blanking. The soundcard uses speakers of the monitor. Sound is muted when the screen blanks due to a bug in aty128fb.c. Here is a fragment of linux/fb.h /* VESA Blanking Levels */ #define VESA_NO_BLANKING 0 #define VESA_VSYNC_SUSPEND 1 #define VESA_HSYNC_SUSPEND 2 #define VESA_POWERDOWN 3 enum { /* screen: unblanked, hsync: on, vsync: on */ FB_BLANK_UNBLANK = VESA_NO_BLANKING, /* screen: blanked, hsync: on, vsync: on */ FB_BLANK_NORMAL = VESA_NO_BLANKING + 1, /* screen: blanked, hsync: on, vsync: off */ FB_BLANK_VSYNC_SUSPEND = VESA_VSYNC_SUSPEND + 1, /* screen: blanked, hsync: off, vsync: on */ FB_BLANK_HSYNC_SUSPEND = VESA_HSYNC_SUSPEND + 1, /* screen: blanked, hsync: off, vsync: off */ FB_BLANK_POWERDOWN = VESA_POWERDOWN + 1 }; So FB_BLANK_NORMAL is 1, FB_BLANK_VSYNC_SUSPEND is 2, FB_BLANK_HSYNC_SUSPEND is 3, FB_BLANK_POWERDOWN is 4. And now: blank = FB_BLANK_NORMAL (1) blank & FB_BLANK_HSYNC_SUSPEND (1 & 3) is true, so normal blank caused hsync suspend and sound is muted.

2007-05-08x86, serial: convert legacy COM ports to platform devicesBjorn Helgaas
Make x86 COM ports into platform devices and don't probe for them if we have PNP. This prevents double discovery, where a device was found both by the legacy probe and by 8250_pnp, e.g., serial8250: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A 00:02: ttyS0 at I/O 0x3f8 (irq = 4) is a 16550A This also means IRDA devices without a UART PNP ID will no longer be claimed by the serial driver, which might require changes in IRDA drivers and administration. In addition to this patch, you may need to configure a setserial init script, e.g., /etc/init.d/setserial, so it doesn't poke legacy UART stuff back in. On Debian, "dpkg-reconfigure setserial" with the "kernel" option does this. To force the old legacy probe behavior even when we have PNPBIOS or ACPI, load the new legacy_serial module (or build 8250 static) with the "legacy_serial.force" option.

2007-05-08smsc-ircc2: add PNP supportBjorn Helgaas
Claim devices using PNP, unless the user explicitly specified device addresses. This can be disabled with the "smsc-ircc2.nopnp" option. This removes the need for probing legacy addresses and helps untangle IR devices from serial8250 devices. Sometimes the SMC device is at a legacy COM port address but does not use the legacy COM IRQ. In this case, claiming the device using PNP rather than 8250 legacy probe means we can automatically use the correct IRQ rather than forcing the user to use "setserial" to set the IRQ manually. If the PNP claim doesn't work, make sure you don't have a setserial init script, e.g., /etc/init.d/setserial, configured to poke in legacy COM port resources for the IRDA device. That causes the serial driver to claim resources needed by this driver.

2007-05-08PNP: notice whether we have PNP devices (PNPBIOS or PNPACPI)Bjorn Helgaas
This series converts i386 and x86_64 legacy serial ports to be platform devices and prevents probing for them if we have PNP. This prevents double discovery, where a device was found both by the legacy probe and by 8250_pnp. This also prevents the serial driver from claiming IRDA devices (unless they have a UART PNP ID). The serial legacy probe sometimes assumed the wrong IRQ, so the user had to use "setserial" to fix it. Removing the need for setserial to make IRDA devices work seems good, but it does break some things. In particular, you may need to keep setserial from poking legacy UART stuff back in by doing something like "dpkg-reconfigure setserial" with the "kernel" option. Otherwise, the setserial-discovered "UART" will claim resources and prevent the IRDA driver from loading. This patch: If we can discover devices using PNP, we can skip some legacy probes. This flag ("pnp_platform_devices") indicates that PNPBIOS or PNPACPI is enabled and should tell us about builtin devices.

2007-05-08rtc: remove "RTC_ALM_SET mode" bugsDavid Brownell
This fixes a common glitch in how RTC drivers handle two "set alarm" modes, by getting rid of the surprising/hidden one that was rarely implemented correctly (and which could expose nonportable hardware-specific behavior). The glitch comes from the /dev/rtcX logic implementing the legacy RTC_ALM_SET (limited to 24 hours, needing RTC_AIE_ON) ioctl on top of the RTC driver call providing access to the newer RTC_WKALM_SET (without those limitations) by initializing the day/month/year fields to be invalid ... that second mode. Now, since few RTC drivers check those fields, and most hardware misbehaves when faced with invalid date fields, many RTC drivers will set bogus alarm times on those RTC_ALM_SET code paths. (Several in-tree drivers have that issue, and I also noticed it with code reviews on several new RTC drivers.) This patch ensures that RTC drivers never see such invalid alarm fields, by moving some logic out of rtc-omap into the RTC_ALM_SET code and adding an explicit check (which will prevent the issue on other code paths).

This works around a bug seen in some RTC-related ACPI table entries, and tweaks related diagnostics to follow the ACPI convention. The bug prevents misleading boot-time messages: platforms affected by this bug wrongly report they can support alarms up to one year in the future, when in fact the longest alarm is just 24 hours. That will surprise anyone trying to use those extended alarms.
