serial: sh-sci: Compute the regshift value for SCI ports

2017-01-19T13:17:05Z

SCI instances found in SH SoCs have different spacing between registers depending on the SoC. The platform data contains a regshift field that tells the driver by how many bits to shift the register offset to compute its address. We can compute the regshift value automatically based on the memory resource size, there's no need to pass the value through platform data. Fix the sh7750 SCI and sh7760 SIM port memory resources length to ensure proper computation of the regshift value.

serial: sh-sci: Remove unused platform data capabilities field

2017-01-19T13:17:05Z

The field isn't set by any platform but is only used internally in the driver to hold data parsed from DT. Move it to the sci_port structure. Signed-off-by: Laurent Pinchart Reviewed-by: Geert Uytterhoeven Signed-off-by: Greg Kroah-Hartman

serial: sh-sci: Remove manual break debouncing

2017-01-19T13:17:05Z

The sh-sci driver implements manual break debouncing for a few SH platforms by reading the value of the RX pin port register. This feature is optional and the driver considers all negative or zero values of the platform data port_reg field as invalid. As the four platforms that set the field to a register address all use an address higher than 0x7fffffff, the driver will always consider the value as invalid and never perform debouncing. The feature is unused, remove it. Debouncing could be implemented properly in the future using the pinctrl and GPIO APIs if desired.

serial: sh-sci: Remove the platform data dma slave rx/tx channel IDs

2017-01-19T13:17:05Z

Only SH platforms still use platform data for the sh-sci, and none of them declare DMA channels connected to the SCI. Remove the corresponding platform data fields and simplify the driver accordingly. Signed-off-by: Laurent Pinchart Reviewed-by: Geert Uytterhoeven Signed-off-by: Greg Kroah-Hartman

serial: sh-sci: Add BRG register definitions

2015-12-17T10:18:44Z

Add register definitions for the Baud Rate Generator for External Clock (BRG), as found in some SCIF and in HSCIF, including a new regtype for the "SH-4(A)"-derived SCIF variant with BRG. Signed-off-by: Geert Uytterhoeven Acked-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.
