serial: sh-sci: Replace hardcoded overrun bit values

2015-05-10T17:06:39Z

Add the missing overrun bit definition for (H)SCIF. Replace overrun_bit by overrun_mask, so we can use the existing defines instead of hardcoded values. Signed-off-by: Geert Uytterhoeven Signed-off-by: Greg Kroah-Hartman

serial: sh-sci: Replace hardcoded values in SCxSR_*_CLEAR macros

2015-05-10T17:06:38Z

Add the missing overrun error bit in SCxSR on SCIFA/SCIFB and SCIF on SH7705/SH7720/SH7721. Document what the corresponding bit(s) on plain SCIF are used for. Sort the components of SCIF_DEFAULT_ERROR_MASK by reverse definition order. Replace the hardcoded values in the SCxSR_*_CLEAR macros by proper defines. Use bit masks (negations of sets of bits) to make it more obvious which bits are being cleared. Assembler output (on sh) was compared before and after this commit: - For the first branch of the big "#if defined(...) || ..." construct, the code has changed slightly, as 32-bit bitmasks can be loaded in a single instruction, unlike the old large 16-bit constants (the SCxSR register is 16 bit, so we don't care about the top 16 bits), - For the second branch, the generated code is identical.

serial: sh-sci: Add SCIFA/B SCPCR register definitions

2015-05-10T17:06:38Z

Add the register definitions for the Serial Port Control and Data Registers on SCIFA/SCIFB, which are needed for RTS/CTS pin control. Extracted from patches by Magnus Damm . Signed-off-by: Geert Uytterhoeven Signed-off-by: Greg Kroah-Hartman

serial: sh-sci: Add (H)SCIF RTS/CTS pin data register bit definitions

2015-05-10T17:06:38Z

Add the missing register bit definitions to set the RTS pin and read the CTS pin on (H)SCIF. Extracted from patches by Magnus Damm . Signed-off-by: Geert Uytterhoeven Signed-off-by: Greg Kroah-Hartman

serial: sh-sci: Move private definitions to private header file

2015-05-10T17:06:38Z

Move private register definitions and enums from the public header file to the driver private "sh-sci.h" header file. The common Serial Control Register definitions are left in the public header file, as they're needed to fill in plat_sci_port.scscr on legacy systems not using DT.

drivers/tty/serial/sh-sci.h: remove dead reference on ARCH_SH7372

2015-05-06T20:26:57Z

The Kconfig option ARCH_SH7372 has been removed by commit 59b89af1d555 ("ARM: shmobile: sh7372: Remove Legacy C SoC code"). This patch removes the last reference on this Kconfig option. Signed-off-by: Valentin Rothberg Acked-by: Geert Uytterhoeven Signed-off-by: Greg Kroah-Hartman

serial: sh-sci: Move overrun_bit and error_mask fields out of pdata

2013-12-24T02:17:48Z

None of the fields is ever set by board code, and both of them are set in the driver at probe time. Move them out of struct plat_sci_port to struct sci_port. Signed-off-by: Laurent Pinchart Acked-by: Greg Kroah-Hartman Signed-off-by: Simon Horman

serial: sh-sci: remove obsolete Kconfig macros

2013-03-25T21:06:45Z

Support for SH7367 and SH7377 got removed in v3.8. Now remove their last Kconfig macros. Signed-off-by: Paul Bolle Signed-off-by: Greg Kroah-Hartman
