| * Samsung/serial: make the clock source configureableJuergen Beisert2012-07-251-6/+12
| | | | | | | | | | | | | | | | | | Instead of taking the value from somewhere, use the selected architecture to select one. This ensures the selected clock source corresponds to the values setup in the clocks-*.c from the mach directory.

| * Samsung/serial: there is no need to ifdef the slot tableJuergen Beisert2012-07-251-2/+0
| | | | | | | | | | | | | | | | | | The '__maybe_unused' attribute prevents the compiler from warning about an unused variable and the 'static' will remove it entirely if it's not used.

* | serial_ns16550: change the driver's nameAntony Pavlov2012-07-201-1/+1
|/ | | | | | | | | | | | | | | | | | | | | | | | | The name "serial_ns16550" is not handy because the devices will have the names like "serial_ns165500", "serial_ns165501", "serial_ns165502" etc. The names like "ns16550_serial0" and "ns16550_serial1" look much better. Also it is reasonable to make serial driver's names unification. E.g. see the names for drivers in drivers/serial directory: "netx_serial", "mpc5xxx_serial", "altera_serial", "s3c_serial", "imx_serial", "pxa_serial", "blackfin_serial", "stm_serial", "pl010_serial", and even "g_serial" in ./drivers/usb/gadget/serial.c Signed-off-by: Antony Pavlov <antonynpavlov@gmail.com> Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* Support most Samsung SoCs in S3C serial driverAlexey Galakhov2012-05-142-18/+39
| | | | | | | | | | | | | | | | Ok, I assume this should go into separate series. It fits both S5PV210 and S3C6410. This adds support for S3C and S5P architectures (all of my knowledge) to the serial driver. Since the only difference between them is in clock handling, this is moved to an arch-dependent separate function. Most modern architectures should define S3C_UART_HAS_UBRDIVSLOT and S3C_UART_HAS_UINTM.

* netX: UART may not initialize correctly.Michael Trensch2012-04-301-6/+5
| | | | | | | | | | | The netX internal UART latches register settings and internally uses them only if written in the correct order. Other orders may work, but sometimes the UART gets stuck, as the baudrate has not correctly been set.

* ns16550: fix ier selectionAntony Pavlov2012-01-191-0/+2
| | | | | | | | | | | | | | The document "PC16550D Universal Asynchronous Receiver Transmitter with FIFOs" (vers. June 1995, http://www.national.com/ds/PC/PC16550D.pdf) states that IER (Interrupt Enable Register) is accessible if the bit DLAB = 0 (DLAB is bit 7 in LCR; in barebox DLAB known as LCR_BKSE).

| | | | | | | | | | There are major differences in the clock tree of the S3C24xx family and the more recent CPUs of the S3C family. Keep the S3C24XX clock routines separate to avoid an ifdef hell.

* uart drivers: use xzalloc instead of xmallocSascha Hauer2011-12-239-9/+9
| | | | | | | | | | | | | | | | | | | The flags in struct console_device have to be initialized to zero. Otherwise the following can happen: - console_register sets the initial baudrate of a new console before we set the global console init state to CONSOLE_INIT_FULL. - In console_baudrate_set we test whether the current console is active which may be true because of unitialized flags. - we then call getc() to wait for the user to accept the new settings and we are stuck because of the CONSOLE_UNINITIALIZED state we will never get anything from getc(). Looking back this explains some cases for me when barebox refused to start and I really wonder why this did not become a more visible problem before.
