3 * src/ser_16x5x.c (pc_serial_init):
4 Allow platform to define CYG_IO_SERIAL_GENERIC_16X5X_BAUD_GENERATOR if the
5 baud rate clock (values) cannot be known at compile time. In this case,
6 the baud rate generator values are provided by platform specific code,
7 computed when the device is first initialized.
9 2003-07-16 Jonathan Larmour <jifl@eCosCentric.com>
11 * src/ser_16x5x.c (CYG_IO_SERIAL_GENERIC_16X5X_INT_PRIORITY): Add
12 so that the calling hardware-specific drivers can override priorities.
13 Clarify flow control comment.
15 2003-03-18 Gary Thomas <gary@mlbassoc.com>
17 * src/ser_16x5x.c (pc_serial_set_config):
18 Flag for CYG_IO_SET_CONFIG_SERIAL_HW_RX_FLOW_THROTTLE is 32 bits.
20 2003-02-24 Jonathan Larmour <jifl@eCosCentric.com>
22 * cdl/ser_generic_16x5x.cdl: Remove irrelevant doc link.
24 2001-06-19 Jesper Skov <jskov@redhat.com>
26 * cdl/ser_generic_16x5x.cdl: Only define
27 CYGDAT_IO_SERIAL_DEVICE_HEADER when necessary.
29 2001-06-18 Jonathan Larmour <jlarmour@redhat.com>
31 * src/ser_16x5x.c (pc_serial_set_config): Fix length check typo
33 2001-06-18 Jesper Skov <jskov@masala.cambridge.redhat.com>
35 * src/ser_16x5x.c (LCR_PE): Set correct bits (from Boris V. Guzhov)
37 2001-06-08 Jonathan Larmour <jlarmour@redhat.com>
39 * src/ser_16x5x.c: Support FIFOs better by detecting what we've got,
40 and only acting if we have a _working_ FIFO.
41 Assert on unhandled serial interrupt type.
43 2001-03-13 Jonathan Larmour <jlarmour@redhat.com>
45 * cdl/ser_generic_16x5x.cdl: Rename
46 CYGPKG_IO_SERIAL_GENERIC_16X5X_FIFO_OPTIONS to
47 CYGPKG_IO_SERIAL_GENERIC_16X5X_FIFO and make it a boolean. Clarify
48 descriptions a little.
50 * src/ser_16x5x.c (serial_config_port): Only program FCR if FIFO
52 Don't bother with intermediate _fifo_thresh.
55 2001-03-13 Jesper Skov <jskov@redhat.com>
57 * cdl/ser_generic_16x5x.cdl: Removed the default value.
59 2001-03-09 Julian Smart <julians@redhat.com>
60 Removed default value for flavor none in
61 CYGPKG_IO_SERIAL_GENERIC_16X5X_FIFO_OPTIONS since it
62 causes an assert in libcdl
64 2001-03-05 Jesper Skov <jskov@redhat.com>
65 2001-02-15 Dave Airlie <airlied@parthus.com>
67 * src/ser_16x5x.c (serial_config_port): Add support for setting
68 a FIFO RX Threshold via CDL
70 * cdl/ser_generic_16x5x.cdl: Add support for setting a FIFO
73 2001-01-24 Dave Airlie <airlied@parthus.com>

78 2000-12-19 Dave Airlie <airlied@parthus.com>
80 * src/ser_16x5x.c: Add defines for FIFO control register
81 (serial_config_port): Use these defines.
83 2000-12-07 Jesper Skov <jskov@redhat.com>
85 * src/ser_16x5x.c (ISR_LS): Corrected value. Spotted by Dave Airlie.
87 2000-09-18 Jesper Skov <jskov@redhat.com>
89 * src/ser_16x5x.c: Allow clients to specify register
90 stepping. Rename a type. Fix compile error.
92 2000-09-14 Jesper Skov <jskov@redhat.com>
94 * src/ser_16x5x.c: Moved ARM/PID driver to provide generic 16x5x
95 driver. Rewritten to use HAL IO macros. Still needs some polish
96 and configury to properly support all the various target
97 controllers that may only have a partial set of the features.
98 * cdl/ser_generic_16x5x.cdl: Same.
100 * Removed non-PID related ChangeLog entries.
102 ----------------------------------------------------------------------------
103 2000-08-24 Jonathan Larmour <jlarmour@redhat.co.uk>
105 * src/pid_serial_with_ints.c (pid_serial_DSR): Remove accidental
106 OVERRUNERR check duplication
108 2000-08-01 Jonathan Larmour <jlarmour@redhat.co.uk>
110 * src/pid_serial_with_ints.c: Throughout, add support for line status
111 and modem status callbacks, hardware RTS/CTS and DSR/DTR flow control
112 (pid_serial_set_config): Now use keys to make
115 * src/pid_serial.h: Add more line status, interrupt status and modem
116 status register definitions
118 * cdl/ser_arm_pid.cdl: Implements flow control and line status
121 2000-06-22 Hugo Tyson <hmt@cygnus.co.uk>
123 * cdl/<yournamehere>.cdl: Remove the comment on the empty
124 include_files directive; the tools now support this correctly.
125 This keeps internal include files internal.
127 2000-06-09 Jesper Skov <jskov@redhat.com>
129 * src/pid_serial_with_ints.c:
131 Cleaned up defines and made DSR handle all received characters.
132 (Dave Airlie (airlied at parthus dot com))
134 2000-04-11 Hugo Tyson <hmt@cygnus.co.uk>
136 * cdl/ser_arm_pid.cdl: Change the parent from CYGPKG_IO_SERIAL
137 (which is enabled most of the time) to CYGPKG_IO_SERIAL_DEVICES
138 (which is not...) thus allowing convenient control independent of
139 platform. Also enable all individual devices by default, now, so
140 that they can be enabled simply by enabling the above new parent.
142 2000-04-07 Hugo Tyson <hmt@cygnus.co.uk>
144 * ecos.db: Re-organize device packages. This is a massive change
145 involving deleting all the sources for serial and ethernet drivers
146 from where they used to live in
147 packages/io/serial/current/src/ARCH/PLATFORM.[ch]
148 packages/net/drivers/eth/PLATFORM/current/src/...
149 and reinstating them in
150 packages/devs/serial/ARCH/PLATFORM/current/src/...
151 packages/devs/eth/ARCH/PLATFORM/current/src/...
153 All these new packages are properly defined in ecos.db, and are
154 all of type "hardware" so that a "target" can grab them.
156 This directory layout is descriptive of the devices we have right
157 now, arch and platform are separate levels just to make it easier
158 to navigate in the filesystem and similar to the HAL structure in
161 It is *not* prescriptive of future work; for example, the mythical
162 common highly-portable 16550 serial driver which works on many
163 targets would be called "devs/serial/s16550/current", or a serial
164 device for a particular board (cogent springs to mind) that can
165 work with different CPUs fitted is "devs/serial/cogent/current".
167 Changelogs have been preserved and replicated over all the new
168 packages, so that no history is lost.
170 The contents of individual source files are unchanged; they build
171 in just the same emvironment except for a very few cases where the
172 config file name changed in this movement.
174 Targets in ecos.db have been redefined to bring in all relevant
175 hardware packages including net and serial drivers (but the newly
176 included packages are only active if their desired parent is
179 The names of CDL options (and their #defines of course) stay the
180 same for the serial drivers, for backward compatibility.
182 * templates/*/current.ect: these have had CYGPKG_IO_SERIAL added
183 rather than it being in (almost) all target definitions.
185 2000-01-03 Gary Thomas <gthomas@cygnus.co.uk>
187 * src/arm/pid_serial_with_ints.c: Fix namespace pollution -
188 serial_devio => cyg_io_serial_devio
190 1999-12-06 Gary Thomas <gthomas@cygnus.co.uk>
192 * src/arm/pid_serial_with_ints.c (pid_serial_DSR): Add loop to handle
193 case where an interrupt represents multiple events.
195 1999-10-26 Jesper Skov <jskov@cygnus.co.uk>
197 * src/arm/pid_serial.h: Added BE support.
199 1999-10-25 Gary Thomas <gthomas@cygnus.co.uk>
201 * src/arm/pid_serial.h (ISR_RxTO): Define - character received but
202 not handled "promptly".
204 * src/arm/pid_serial_with_ints.c (pid_serial_DSR): Handle rcv
205 interrupts properly (can't ignore them even with TO bit set).
207 1999-06-20 Gary Thomas <gthomas@cygnus.co.uk>
209 * src/arm/pid_serial_with_ints.c: Use #include to get 'diag_printf()'
212 1999-05-14 Jesper Skov <jskov@cygnus.co.uk>
214 * src/arm/pid_serial_with_ints.c:

225 Update CDL to follow naming conventions.
227 * src/arm/pid_serial_with_ints.c (pid_serial_config_port): Change
228 so that the physical port is not modified unless the provided
229 configuration is valid.

246 Moved include statement to avoid warnings.
