2005-11-12[SERIAL] Claim Wacom tablet device on HP tc1100 tabletBjorn Helgaas
Claim the WACF005 device. This is the pen display pointing device on the HP Compaq tc1100 Tablet PC. More information about using this device, including using it as an X pointer device: http://www.theory.bham.ac.uk/staff/schofield/linux/tc1100/ Christopher Kemp <ck231@cam.ac.uk> did the legwork of determining that the WACF005 is really just a plain old UART and doing an initial ACPI driver (before we had PNPACPI), and David Ludlow <dave@adsllc.com> confirmed that PNPACPI + the attached patch is now sufficient: pnp: Device 00:05 activated. ttyS4 at I/O 0x300 (irq = 4) is a 16550A Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

2005-11-12[SERIAL] don't disable xscale serial ports after autoconfigLennert Buytenhek
xscale-type UARTs have an extra bit (UUE) in the IER register that has to be written as 1 to enable the UART. At the end of autoconfig() in drivers/serial/8250.c, the IER register is unconditionally written as zero, which turns off the UART, and makes any subsequent printch() hang the box. Since other 8250-type UARTs don't have this enable bit and are thus always 'enabled' in this sense, it can't hurt to enable xscale-type serial ports all the time as well. The attached patch changes the autoconfig() exit path to see if the port has an UUE enable bit, and if yes, to write UUE=1 instead of just putting a zero into IER, using the same test as is used at the beginning of serial8250_console_write().

This patch fixes an issue reported by Coverity in serial/serial_core.c Error reported: Variable "&((info)->tty)->flags" tracked as NULL was passed to a function that dereferences it. The later statements in the function assumes 'info->tty != NULL', so this check is not necessary. Probably a 'BUG_ON(info->tty == NULL)' can be added.

2005-10-28[PATCH] DRIVER MODEL: Get rid of the obsolete tri-level suspend/resume callbacksRussell King
In PM v1, all devices were called at SUSPEND_DISABLE level. Then all devices were called at SUSPEND_SAVE_STATE level, and finally SUSPEND_POWER_DOWN level. However, with PM v2, to maintain compatibility for platform devices, I arranged for the PM v2 suspend/resume callbacks to call the old PM v1 suspend/resume callbacks three times with each level in order so that existing drivers continued to work. Since this is obsolete infrastructure which is no longer necessary, we can remove it. Here's an (untested) patch to do exactly that.
