2008-04-28serial 8250: tighten test for using backup timerAlex Williamson
Thomas Koeller had reported an issue where a device that had been making use of the UART_BUG_TXEN code in the 8250 driver was mistakenly being caught by the backup timer test, causing the device to work improperly. To fix this, tighten the test requirements to enable the backup timer workaround. The backup timer is really meant to catch UARTs that don't re-assert the THRE interrupt. The expectation is that they do initially assert THRE. This patch clarifies the test.

Russell King noticed this one: We have to avoid replacing B0 when we pick a baud rate for a "hung up" port.

2008-04-28Fix tty speed handling on 8250Alan Cox
We try and write the correct speed back but the serial midlayer already mangles the speed on us and that means if we request B0 we report back B9600 when we should not.

2008-04-17[ARM] 4995/1: <IMX UART>: Do not use URXD_CHARRDY for pollingSascha Hauer
Do not use the URXD_CHARRDY bit for polling for new characters. This works on i.MX1, but on MX31 the datasheet states that this bit should not be used for polling. On MX27 it is even worse, here we get a bus error when we access the read FIFO when no character is present. Instead, use USR2_RDR (receive data ready) bit.

- get rid of `model = "UCC"' in the ucc nodes It isn't used anywhere, so remove it. If we'll ever need something like this, we'll use compatible property instead. - replace last occurrences of device-id with cell-index. Drivers are modified for backward compatibility's sake.

2008-04-17[POWERPC] cpm_uart: Allocate DPRAM memory for SMC ports on CPM2-based platforms.Laurent Pinchart
This patch allocates parameter RAM for SMC serial ports without relying on previous initialisation by a boot loader or a wrapper layer. SMC parameter RAM on CPM2-based platforms can be allocated anywhere in the general-purpose areas of the dual-port RAM. The current code relies on the boot loader to allocate a section of general-purpose CPM RAM and gets the section address from the device tree. This patch modifies the device tree address usage to reference the SMC parameter RAM base pointer instead of a pre-allocated RAM section and allocates memory from the CPM dual-port RAM when initialising the SMC port. CPM1-based platforms are not affected.

2008-04-15serial: fix platform driver hotplug/coldplugKay Sievers
Since 43cc71eed1250755986da4c0f9898f9a635cb3bf, the platform modalias is prefixed with "platform:". Add MODULE_ALIAS() to the hotpluggable serial platform drivers, to re-enable auto loading. NOTE that Kconfig for some of these drivers doesn't allow modular builds, and thus doesn't match the driver source's unload support. Presumably their unload code is buggy and/or weakly tested...

2008-04-02[POWERPC] of_serial: Fix possible null dereference.Stephen Neuendorffer
The of_serial driver queries the current-speed property and attempts to use it to register the custom_divisor property of the uart_port. However, if current-speed is not set, then this code will dereference a bad pointer. The fix is to only set custom_divisor when a current-speed property appears in the device tree.

2008-04-02atmel_serial: fix uart/console concurrent accessMarc Pignat
Strange chars appear on the serial port when a printk and a printf happens at the same time. This is caused by the pdc sending chars while atmel_console_write (called from printk) is executing Concurent access of uart and console to the same port leads to corrupted data to be transmitted, so disable tx dma (PDC) while writing to the console.
