2021-06-24Revert "tty: serial: Add UART driver for Cortina-Access platform"Greg Kroah-Hartman3-818/+0
This reverts commit b61c8bf4694b5115766849378dcb8787ff54e65e. It never made it to a public mailing list and still needs some work based on the review comments. So revert it for now.

2021-06-18s390/hvc_iucv: Remove power management supportJulian Wiedmann1-51/+0
Power management support was removed for s390 with commit 394216275c7d ("s390: remove broken hibernate / power management support"). Remove the hvc_iucv_driver, but keep the device struct around so that it can continue to provide the hvc_iucv_dev_attr_groups attributes.

2021-06-18mxser: introduce mxser_16550A_or_MUST helperJiri Slaby1-13/+13
This check is used in the code on many places. Either in positive or negative form. So introduce a helper called mxser_16550A_or_MUST for this purpose. And replace all the occurrences. This simplifies many ifs in there.

2021-06-18mxser: rename flags to old_speed in mxser_set_serial_infoJiri Slaby1-3/+3
Local 'flags' are used to store speed in mxser_set_serial_info, not actual flags (by doing & ASYNC_SPD_MASK). So rename 'flags' to 'old_speed' (after what it is).

2021-06-18mxser: use port variable in mxser_set_serial_infoJiri Slaby1-5/+5
mxser_set_serial_info already defined a local 'port' of type struct tty_port. So use it in the code everywhere. This eliminates some text from the code there.

2021-06-18mxser: access info->MCR under info->slockJiri Slaby1-2/+2
info->MCR is protected by info->slock all over the code. Extend the lock in mxser_tiocmget around the info->MCR fetch too. It likely doesn't change anything, but it's always good to be consistent.

2021-06-18mxser: fix typos around enhanced modeJiri Slaby1-9/+9
Fix spelling of "enhanced" in macros and comments around them. While "enchance" comes from the original Moxa's driver, I don't think it was meant to be that. From the context, they obviously mean "enhanced".

2021-06-18mxser: decrypt FCR valuesJiri Slaby1-2/+6

2021-06-18mxser: remove xmit_cnt < 0 testsJiri Slaby1-4/+4

2021-06-18mxser: introduce and use start/stop_tx helpersJiri Slaby1-43/+37
Starting and stopping TX is performed on many places in the driver. It is repeated outb and info->IER modification. Create few helpers (__mxser_start_tx, mxser_start_tx, __mxser_stop_tx) and use them in the code instead of open coding. This should be a base for an uart driver for this device in the future.

2021-06-18mxser: extract and dedup CTS handlingJiri Slaby1-54/+33

2021-06-18mxser: don't start TX from tty_operations::put_charJiri Slaby1-11/+1
TX is not supposed to be started from tty_operations::put_char. Line disciplines ought to call tty_operations::put_char several times and then do a single tty_operations::flush_chars to start TX. Fix this in mxser by removing TX startup from mxser_put_char.

2021-06-18mxser: remove pointless ioaddr checksJiri Slaby1-10/+1
struct mxser_port::ioaddr can never be NULL once set in ->probe. Hence the checks for it are pointless. Remove them. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Link: https://lore.kernel.org/r/20210618061516.662-55-jslaby@suse.cz Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2021-06-18mxser: alloc only needed # of portsJiri Slaby1-2/+3
Many boards have only 2 ports. But we always allocate 8 ports (struct mxser_port) in each struct mxser_board. Switch this to an empty/variable sized array ([]) and allocate the needed number of ports using struct_size helper in ->probe.

2021-06-18mxser: alloc struct mxser_board dynamicallyJiri Slaby1-10/+11
There is no need to preallocate an array of four struct mxser_board's. In most cases a single board or two will be present in a machine. So allocate struct mxser_board as needed in ->probe. This makes mxser_boards a bit array. There we store which indexes are free (unallocated).

2021-06-18mxser: make mxser_board::idx really an indexJiri Slaby1-6/+7
mxser_board::idx is named as index, but actually contain a base. So assign index there. And for base, introduce a local variable. This is needed for the next patch (use index as a bit index).

2021-06-18mxser: rework and simplify mxser_openJiri Slaby1-7/+4
In mxser_open, tty->port is already set thanks to tty_port_register_device in ->probe. So we can simply use container_of to deduce the struct mxser_port's pointer. Thus avoiding divisions and complex computations.

2021-06-18mxser: remove mxser_cardinfoJiri Slaby1-72/+41
Now that mxser_cards array (of struct mxser_cardinfo) contains only port count and a quirk, we can encode these two directly into pci_device_id::driver_data. And we can remove this struct completely.

2021-06-18mxser: remove info message from probeJiri Slaby1-30/+26
There is a dev_info in ->probe which prints device's name, bus and slot numbers. All these can be fetched from the lspci output. So remove this useless print.

2021-06-18mxser: move request irq to probe and switch to managedJiri Slaby1-21/+9

2021-06-18mxser: pci, switch to managed resourcesJiri Slaby1-11/+3

2021-06-18mxser: clean up the rest of MUST helpersJiri Slaby1-85/+12
Clean up the rest of MUST helpers. They all can use the newly added mxser_must_set_EFR. And passing a bool instead of having two functions (_enable+_disable) simplifies the code a lot too.

2021-06-18mxser: introduce mxser_must_select_bank and use itJiri Slaby1-58/+16
Again, selecting a bank in the EFR register is duplicated many times. Extract it to a separate function (mxser_must_select_bank) and use it on all the places. This cleans up most of the helpers.

2021-06-18mxser: dedup mxser_must_set_enhance_modeJiri Slaby1-20/+22
There are multiple copies of setting the EFR register. Separate it to a new universal function called __mxser_must_set_EFR.

2021-06-18mxser: don't allocate MXSER_PORTS + 1Jiri Slaby1-20/+3
The MXSER_PORTS's tty_device is never registered and neither its tty_port instance exists. Hence, it's quite pointless to allocate it. It used to be used for global information fetches via ioctls. We have just removed these as non-existent tty_device+tty_port was exactly the reason to remove the ioctls.

1) MOXA_ASPP_MON_EXT is broken at least since commit ecbbfd44a08f (TTY: move tty buffers to tty_port) in 2012. 2) The ioctl definitions were never exposed to userspace, so noone should actually be reliably using them. 3) They're not even mentioned in any of the mxser utilities. So remove all these mxser-special ioctls: MOXA_ASPP_MON, MOXA_ASPP_MON_EXT, and MOXA_SDS_RSTICOUNTER.

2021-06-18mxser: remove MOXA_SET_BAUD_METHOD ioctlJiri Slaby1-12/+1
1) The semantics are defined exactly nowhere. 2) The ioctl definition was never exposed to userspace, so noone should actually be reliably using this. 3) It's not even mentioned in any of the mxser utilities. Provided the above, remove this mxser-special ioctl.

2021-06-18mxser: remove MOXA_GET_MAJOR deprecated ioctlJiri Slaby1-7/+0
MOXA_GET_MAJOR was deprecated in commit 41aee9a121fd (Char: mxser, ioctl cleanup) in 2008. Remove this ioctl finally. Signed-off-by: Jiri Slaby <jslaby@suse.cz> Link: https://lore.kernel.org/r/20210618061516.662-23-jslaby@suse.cz Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2021-06-18mxser: drop UART_MCR_AFE and UART_LSR_SPECIAL definesJiri Slaby1-5/+2
* UART_MCR_AFE is a redefinition of serial_reg.h's one. * UART_LSR_SPECIAL is a redefinition of serial_reg.h's UART_LSR_BRK_ERROR_BITS. So remove both and replace the latter uses by already defined UART_LSR_BRK_ERROR_BITS.
