TTY: 8250, revert module name change In 3.7 the 8250 module name was changed unintentionally from 8250 to 8250_core by commit 835d844d1a28efba81d5aca7385e24c29d3a6db2 (8250_pnp: do pnp probe before legacy probe). We then had to re-introduce the old module options to ensure the old good 8250.nr_uart & co. still work. This can be done only by a very dirty hack and we did it in f2b8dfd9e480c3db3bad0c25c590a5d11b31f4ef (serial: 8250: Keep 8250.<xxxx> module options functional after driver rename). That is so damn ugly so that I decided to revert to the old module name and deprecate the new 8250_core options present in 3.7 and 3.8 only. The deprecation will happen in the following patch. Note that this patch changes the hack above to support "8250_core.*", because we now have "8250.*" natively.

serial: 8250: Integrate Fintek into 8250_base The 8250_fintek driver advertises as the PNP0501 driver; however this conflicts with the standard 16550A uart PNP0501. The conflict causes the 8250_fintek driver to load with _every_ PNP0501, but never probe, and causing the entire 8250 driver stack to unload if the 8250_fintek driver is unloaded (modprobe doesn't know that 8250_pnp rather than 8250_fintek claimed the resource). This patch merges the Fintek driver into 8250_base. On autoconfig_16550 the device is probed to verify if it is a FINTEK device or not. This custom probing can be disabled completely via configuration. When a Fintek device is not probed it will behave as a standard 16550A device, with no RS485 capabilities.

serial: bcm2835: add driver for bcm2835-aux-uart The bcm2835 SOC contains an auxiliary uart, which is very close to the ns16550 with some differences. The big difference is that the uart HW is not using an internal divider of 16 but 8, which results in an effictive baud-rate being twice the requested baud-rate. This driver handles this device correctly and handles the difference in the HW divider by scaling up the clock by a factor of 2. The approach to write a separate (wrapper) driver instead of using a multiplying clock and "ns16550" as compatibility in the device-tree has been recommended by Stephen Warren.

serial8250-em: Emma Mobile UART driver V2 This is V2 of the Emma Mobile 8250 platform driver. The hardware itself has according to the data sheet up to 64 byte FIFOs but at this point we only make use of the 16550 compatible mode. To support this piece of hardware the common UART registers need to be remapped, and the access size differences need to be handled. The DLL and DLM registers can due to offset collision not be remapped easily, and because of that this driver makes use of ->dl_read() and ->dl_write() callbacks. This in turn requires a registration function that takes 8250-specific paramenters. Future potential enhancements include DT support, early platform driver console and fine grained PM.

tty: serial: Add 8250-core based omap driver This patch provides a 8250-core based UART driver for the internal OMAP UART. The long term goal is to provide the same functionality as the current OMAP uart driver and DMA support. I tried to merge omap-serial code together with the 8250-core code. There should should be hardly a noticable difference. The trigger levels are different compared to omap-serial: - omap serial TX: Interrupt comes after TX FIFO has room for 16 bytes. TX of 4096 bytes in one go results in 256 interrupts RX: Interrupt comes after there is on byte in the FIFO. RX of 4096 bytes results in 4096 interrupts. - this driver TX: Interrupt comes once the TX FIFO is empty. TX of 4096 bytes results in 65 interrupts. That means there will be gaps on the line while the driver reloads the FIFO. RX: Interrupt comes once there are 48 bytes in the FIFO or less over "longer" time frame. We have 1 / 11520 * 10^3 * 16 => 1.38… ms 1.38ms to react and purge the FIFO on 115200,8N1. Since the other driver fired after each byte it had ~5.47ms time to react. This _may_ cause problems if one relies on no missing bytes and has no flow control. On the other hand we get only 85 interrupts for the same amount of data. It has been only tested as console UART on am335x-evm, dra7-evm and beagle bone. I also did some longer raw-transfers to meassure the load. The device name is ttyS based instead of ttyO. If a ttyO based node name is required please ask udev for it. If both driver are activated (this and omap-serial) then this serial driver will take control over the device due to the link order v9…v10: - Tony noticed that omap3 won't show anything after waking up from core off. In v9 I reworked the register restore and set IER to 0 by accident. This went unnoticed because start_tx usually sets ier (either due to DMA bug or due to TX-complete IRQ). - dropped EFR and SLEEP from capabilities. We do have both but nobody should touch it. We already handle SLEEP ourself. - make the private copy of the registers (like EFR) u8 instead u32 - drop MDR1 & DL[ML] reset in restore registers. Does not look required it is set to the required value later. - update MDR1 & SCR only if changed. - set MDR1 as the last thing. The errata says that we should setup everything before MDR1 set. - avoid div by 0 in omap_8250_get_divisor() if baud rate gets very large (Frans Klaver fixed the same thing omap-serial) - drop "is in early stage" from Kconfig. v8…v9: - less on a file seems to hang the am335x after a while. I believe I introduce this bug a while ago since I can reproduce this prior to v8. Fixed by redoing the omap8250_restore_regs() v7…v8: - redo the register write. There is now one function for that which is used from set_termios() and runtime-resume. - drop PORT_OMAP_16750 and move the setup to the omap file. We have our own set termios function anyway (Heikki Krogerus) - use MEM instead of MEM32. TRM of AM/DM37x says that 32bit access on THR might result in data abort. We only need 32bit access in the errata function which is before we use 8250's read function so it doesn't matter. v4…v7: - change trigger levels after some tests with raw transfers. v3…v4: - drop RS485 support - wire up ->throttle / ->unthrottle v2…v3: - wire up startup & shutdown for wakeup-irq handling. - RS485 handling (well the core does). v1…v2: - added runtime PM. Could somebody could please double check this? - added omap_8250_set_termios() Reviewed-by: Tony Lindgren <tony@atomide.com> Tested-by: Tony Lindgren <tony@atomide.com> Tested-by: Frans Klaver <frans.klaver@xsens.com> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Reviewed-by: Peter Hurley <peter@hurleysoftware.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

serial: 8250_lpss: split LPSS driver to separate module The SoCs, such as Intel Braswell, have DesignWare UART IP. Split out the support of such chips to a separate module which also will be used for Intel Quark later. The rationale to have the separate driver to be existing: - Do not contaminate 8250_pci.c anymore with LPSS related quirks - All of them are using same DMA engine and they are Designware IP which means that in the future we might share the code between 8250_dw.c and 8250_lpss.c - It reduces the kernel memory footprint on non-X86 machines where 8250_pci.c is in use Besides the split the driver also has been refactored, in particular a) the DMA and port setup are separate functions, b) the two new structures lpss8250 and lpss8250_board are introduced to keep necessary data instead of pciserial_board, c) DMA parameters are passed to the DMA setup via mentioned custom structure. Most of the changes are done due to the future support of UART DMA on Intel Quark. The Intel Quark UART DMA support is based on bits taking from BSP code published by Intel earlier. The driver does not use any specific power management. PCI core takes care of the default behaviour during suspend and resume.

serial: 8250_pci: Intel MID UART support to its own driver Intel MID UART quirks require already quite a bit of code in 8250_pci.c. On new Intel platforms where it is used, the integrated DMA engine no longer has its own PCI device, but is instead configured from the UART's MMIO. That means we will have to add even more code for handling just MID UARTs. Instead of adding that to 8250_pci.c, splitting the support of Intel MID UART into its own driver. Handling of the integrated DMA engine becomes much simpler this way. Own driver will also remove the need for things like specific set_termios hooks for every board using this UART, and simplify the handling of it in general.

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.
