serial: pxa: Use uart_prepare_sysrq_char(). The port lock is a spinlock_t which is becomes a sleeping lock on PREEMPT_RT. The driver splits the locking function into two parts: local_irq_save() and uart_port_lock() and this breaks PREEMPT_RT. Delay handling sysrq until port lock is dropped. Remove the special case in the console write routine an always use the complete locking function.

serial: pxa: Use port lock wrappers When a serial port is used for kernel console output, then all modifications to the UART registers which are done from other contexts, e.g. getty, termios, are interference points for the kernel console. So far this has been ignored and the printk output is based on the principle of hope. The rework of the console infrastructure which aims to support threaded and atomic consoles, requires to mark sections which modify the UART registers as unsafe. This allows the atomic write function to make informed decisions and eventually to restore operational state. It also allows to prevent the regular UART code from modifying UART registers while printk output is in progress. All modifications of UART registers are guarded by the UART port lock, which provides an obvious synchronization point with the console infrastructure. To avoid adding this functionality to all UART drivers, wrap the spin_[un]lock*() invocations for uart_port::lock into helper functions which just contain the spin_[un]lock*() invocations for now. In a subsequent step these helpers will gain the console synchronization mechanisms. Converted with coccinelle. No functional change.

serial: make uart_console_write->putchar()'s character an unsigned char Currently, uart_console_write->putchar's second parameter (the character) is of type int. It makes little sense, provided uart_console_write() accepts the input string as "const char *s" and passes its content -- the characters -- to putchar(). So switch the character's type to unsigned char. We don't use char as that is signed on some platforms. That would cause troubles for drivers which (implicitly) cast the char to u16 when writing to the device. Sign extension would happen in that case and the value written would be completely different to the provided char. DZ is an example of such a driver -- on MIPS, it uses u16 for dz_out in dz_console_putchar(). Note we do the char -> uchar conversion implicitly in uart_console_write(). Provided we do not change size of the data type, sign extension does not happen there, so the problem is void. This makes the types consistent and unified with the rest of the uart layer, which uses unsigned char in most places already. One exception is xmit_buf, but that is going to be converted later.

serial: rewrite pxa2xx-uart to use 8250_core pxa2xx-uart was a separate uart platform driver. It was declaring the same device names and numbers as 8250 driver. As a result, it was impossible to use 8250 driver on PXA SoCs. Upon closer examination pxa2xx-uart turned out to be a clone of 8250_core driver. Workaround for Erratum #19 according to Marvel(R) PXA270M Processor Specification Update (April 19, 2010) is dropped. 8250_core reads from FIFO immediately after checking DR bit in LSR. The patch leaves the original SERIAL_PXA driver around. The original driver is just marked DEPRECATED in Kconfig and C source. When the original driver is considered safe to remove, no changes to SERIAL_8250 will be necessary. Compiling SERIAL_8250_CONSOLE and SERIAL_PXA_CONSOLE even without SERIAL_8250_PXA breaks console for SERIAL_PXA. For this reasons, the new and the original drivers are made mutually exclusive.

serial: pxa: make it explicitly non-modular The Kconfig currently controlling compilation of this code is: drivers/tty/serial/Kconfig:config SERIAL_PXA drivers/tty/serial/Kconfig: bool "PXA serial port support" ...meaning that it currently is not being built as a module by anyone. Lets remove the modular code that is essentially orphaned, so that when reading the driver there is no doubt it is builtin-only. We explicitly disallow a driver unbind, since that doesn't have a sensible use case anyway, and it allows us to drop the ".remove" code for non-modular drivers. Since module_init translates to device_initcall in the non-modular case, the init ordering remains unchanged with this commit. Also note that MODULE_DEVICE_TABLE and MODULE_ALIAS are both a no-op for non-modular builds. We also delete the MODULE_LICENSE tag since that information is already contained at the top of the file in the comments.

serial: Fix IGNBRK handling If IGNBRK is set without either BRKINT or PARMRK set, some uart drivers send a 0x00 byte for BREAK without the TTYBREAK flag to the line discipline, when it should send either nothing or the TTYBREAK flag set. This happens because the read_status_mask masks out the BI condition, which uart_insert_char() then interprets as a normal 0x00 byte. SUS v3 is clear regarding the meaning of IGNBRK; Section 11.2.2, General Terminal Interface - Input Modes, states: "If IGNBRK is set, a break condition detected on input shall be ignored; that is, not put on the input queue and therefore not read by any process." Fix read_status_mask to include the BI bit if IGNBRK is set; the lsr status retains the BI bit if a BREAK is recv'd, which is subsequently ignored in uart_insert_char() when masked with the ignore_status_mask.

serial_core: Commonalize crlf when working w/ a non open console port In (efe2f29 kgdboc,kdb: Allow kdb to work on a non open console port) support was added to directly use the "write_char" functions when doing kdb over a non-open console port. This is great, but it ends up bypassing the normal code in uart_console_write() that adds a carriage return before any newlines. There appears to have been a trend to add this support directly in some console driver's poll_put_char() functions. This had a few side effects, including: - In this case we were doing LFCR, not CRLF. This was fixed in uart_console_write() back in (d358788 [SERIAL] kernel console should send CRLF not LFCR) - Not all serial drivers had the LFCR code in their poll_put_char() functions. In my case I was running serial/samsung.c which lacked it. I've moved the handling to uart_poll_put_char() to fix the above problems. Now when I use kdb (and don't point console= to the same UART) I no longer get: [0]kdb> [0]kdb> [0]kdb> Signed-off-by: Doug Anderson <dianders@chromium.org> Reviewed-by: Alan Cox <alan@linux.intel.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

Only tty_port will needed and hence no more tty_port_tty_get in those paths. Now, the one where most of tty_port_tty_get gets removed: tty_flip_buffer_push. IOW we also closed all the races in drivers not using tty_port_tty_get at all yet. Also we move tty_flip_buffer_push declaration from include/linux/tty.h to include/linux/tty_flip.h to all others while we are changing it anyway.

serial: pxa: add spin lock for console write v3: Remove empty line v2: Move local_irq_save() after clk_prepare_enable() v1: At UP mode, when cpu want to print message in kernel, it will invoke peempt_disable and disable irq. So it is safe for UP mode. For SMP mode, it is not safe to protect the HW reigsters. one CPU will run a program which will invoke printf. another CPU will run a program in kernel that invoke printk. So when second CPU is trying to printk, it will do 1. save ier register 2. enable uue bit of ier register 3. push buffer to uart fifo 4 .restore ier register when first CPU want to printf, and it happens between 1 and 4, it will enable thre bit of ier, and waiting for transmit intterupt. while step 4 will make the ier lost thre bit. add spin lock here to protect the ier register for console write.

serial: pxa: add clk_prepare/clk_unprepare calls This patch adds clk_prepare/clk_unprepare calls to the serial/pxa driver by using the helper functions clk_prepare_enable and clk_disable_unprepare.

treewide: Convert uses of struct resource to resource_size(ptr) Several fixes as well where the +1 was missing. Done via coccinelle scripts like: @@ struct resource *ptr; @@ - ptr->end - ptr->start + 1 + resource_size(ptr) and some grep and typing. Mostly uncompiled, no cross-compilers.

tty: move drivers/serial/ to drivers/tty/serial/ The serial drivers are really just tty drivers, so move them to drivers/tty/ to make things a bit neater overall. This is part of the tty/serial driver movement proceedure as proposed by Arnd Bergmann and approved by everyone involved a number of months ago.
