[PATCH] SERIAL: Fix oops when removing suspended serial port

2006-11-04T01:33:46+00:00

[SERIAL] Fix oops when removing suspended serial port A serial card might have been removed when the system is resumed. This results in a suspended port being shut down, which results in the ports shutdown method being called twice in a row. This causes BUGs. Avoid this by tracking the suspended state separately from the initialised state.

[SERIAL] Make uart_match_port() work with all memory mapped UARTs

2006-08-30T09:06:14+00:00

uart_match_port() always fails with UPIO_MEM32, UPIO_AU, and UPIO_TSI cases. Since they match to the memory mapped UARTs, they should be handled just like UPIO_MEM case. Signed-off-by: Sergei Shtylyov Signed-off-by: Russell King

[SERIAL] 8250: add tsi108 serial support

2006-07-09T20:11:09+00:00

The following patch gets rid of CONFIG_TSI108_BRIDGE. I add UPIO_TSI to handle IIR and IER register in serial_in and serial_out. (1) the reason to rewrite serial_in: TSI108 rev Z1 version ERRATA. Reading the UART's Interrupt Identification Register (IIR) clears the Transmit Holding Register Empty (THRE) and Transmit buffer Empty (TEMP) interrupts even if they are not enabled in the Interrupt Enable Register (IER). This leads to loss of the interrupts. Interrupts are not cleared when reading UART registers as 32-bit word. (2) the reason to rewrite serial_out: Check for UART_IER_UUE bit in the autoconfig routine. This section of autoconfig is excluded for Tsi108/109 because bits 7 and 6 are reserved for internal use. They are R/W bits. In addition to incorrect identification, changing these bits (from 00) will make Tsi108/109 UART non-functional.

[SERIAL] Convert fifosize to an unsigned int

2006-07-02T19:45:51+00:00

Some UARTs have more than 255 bytes of FIFO, which can't be represented by an unsigned char. Change the kernel's internal structure to be an unsigned int, but still export an unsigned char via the TIOCGSERIAL ioctl. If the TIOCSSERIAL ioctl provides a fifo size of 0, assume this means "don't change" otherwise we'll corrupt the larger fifo sizes. Signed-off-by: Russell King

[PATCH] devfs: Rename TTY_DRIVER_NO_DEVFS to TTY_DRIVER_DYNAMIC_DEV

2006-06-26T19:25:09+00:00

I've always found this flag confusing. Now that devfs is no longer around, it has been renamed, and the documentation for when this flag should be used has been updated. Also fixes all drivers that use this flag. Signed-off-by: Greg Kroah-Hartman

[ARM] 3523/1: Serial core pm_state

2006-05-16T10:28:49+00:00

Patch from Andrew Victor The serial_core already manages the power state of the UARTs, and therefore it shouldn't suspend a UART which was previously suspended. This patch modifies serial_core only call the UART-specific power-management function if the PM state is actually changing. Signed-off-by: Andrew Victor Signed-off-by: Russell King
