2011-05-18drivercore: revert addition of of_match to struct deviceGrant Likely1-2/+5
Commit b826291c, "drivercore/dt: add a match table pointer to struct device" added an of_match pointer to struct device to cache the of_match_table entry discovered at driver match time. This was unsafe because matching is not an atomic operation with probing a driver. If two or more drivers are attempted to be matched to a driver at the same time, then the cached matching entry pointer could get overwritten. This patch reverts the of_match cache pointer and reworks all users to call of_match_device() directly instead. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-04-19serial/imx: read cts state only after acking cts change irqUwe Kleine-König1-1/+2
If cts changes between reading the level at the cts input (USR1_RTSS) and acking the irq (USR1_RTSD) the last edge doesn't generate an irq and uart_handle_cts_change is called with a outdated value for cts. The race was introduced by commit ceca629 ([ARM] 2971/1: i.MX uart handle rts irq) Reported-by: Arwed Springer <Arwed.Springer@de.trumpf.com> Tested-by: Arwed Springer <Arwed.Springer@de.trumpf.com> Cc: stable@kernel.org # 2.6.14+ Signed-off-by: Uwe Kleine-König <u.kleine-koenig@pengutronix.de> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

2011-03-31sh: sh-sci: Fix double initialization by serial_console_setupNobuhiro Iwamatsu1-13/+6
The driver is initialized in a state with an unknown value by serial_console_setup. And initialization fails. This is caused by the initialization by sci_console_init.

2011-03-31serial: sh-sci: prevent setup of uninitialized serial consoleAlexandre Courbot1-0/+6
Commit 906b17dc089f7fa87e37a9cfe6ee185efc90e0da introduced a condition where the kernel will crash unless a earlyprintk parameter is specified. Without this parameter, sci_console_init is called during early console setup without any port being initialized, and the kernel crashes a little bit later when uart_set_options attemps to invoke set_termios on a port with an ops member equal to NULL. This patch just checks in sci_console_init that the port is properly initialized, and aborts the early console setup if it is not.

The UARTs may be located on different APB buses, thus have different UART clock frequency. The system frequency is not the same (but often) as the UART frequency, rather the APB bus frequency that the APBUART is located at has the same frequency, so this looks at the "freq" property instead.

2011-03-07serial: msm_serial_hs: Add MSM high speed UART driverMayank Rana3-0/+1893
This driver supports UART-DM HW on MSM platforms. It uses the on chip DMA to drive data transfers and has optional support for UART power management independent of Linux suspend/resume and wakeup from Rx. The driver was originally developed by Google. It is functionally equivalent to the version available at: http://android.git.kernel.org/?p=kernel/experimental.git the differences being: 1) Remove wakelocks and change unsupported DMA API. 2) Replace clock selection register codes by macros. 3) Fix checkpatch errors and add inline documentation. 4) Add runtime PM hooks for active power state transitions. 5) Handle error path and cleanup resources if required.

2011-03-04serial: sh-sci: fix deadlock when resuming from S3 sleepAlexandre Courbot1-0/+6
S3 sleep invokes the shutdown callback of the sh-sci driver, which suspends the clocks until they are reactivated by a call to startup. However, before the latter is invoked, sci_set_termios may be called on the port by uart_resume_port. In such cases it will endlessly wait for the TEND bit to raise, which will never happen since the clocks are disabled. This patch ensures that clocks are enabled when ports registers are manipulated within sci_set_termios.
