serial: sh-sci: Add BRG register definitions

2015-12-17T10:18:44+00:00

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.

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

2015-05-10T17:06:38+00:00

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.

serial: sh-sci: Remove platform data mapbase and irqs fields

2013-12-24T12:50:54+00:00

The fields are not used anymore by board files, remove them.

serial: sh-sci: Remove platform data scbrr_algo_id field

2013-12-24T12:50:54+00:00

The field isn't set by any board, remote it.

serial: sh-sci: Rework baud rate calculation

2013-12-24T02:17:53+00:00

Computing the baud rate register value requires knowledge of the
hardware sampling rate. This information is currently encoded in a baud
rate calculation algorithm ID passed through platform data. However, it
can be derived from the port type directly in most cases.

Compute the sampling rate internally in the driver if the baud rate
calculation algorithm ID isn't specified, and allow platforms to
override the sampling rate through platform data in special cases (this
is only required for SCIFA ports on sh7723 and sh7724, the reason needs
to be investigated).

serial: sh-sci: Remove unused GPIO request code

2013-12-24T02:17:50+00:00

The driver requests at initialization time GPIOs passed through platform
data. No platform makes use of this feature, remove it.

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

2013-12-24T02:17:48+00:00

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.

serial: sh-sci: Support resources passed through platform resources

2013-12-24T02:17:44+00:00

Memory and IRQ resources are currently passed to the driver through
platform data. Support passing them through the standard platform
resources mechanism instead. This deprecates platform data resources.
