usb: gadget: Gadget directory cleanup - group legacy gadgets

2014-07-16T17:14:05+00:00

The drivers/usb/gadget directory contains many files. Files which are related can be distributed into separate directories. This patch moves the legacy gadgets (i.e. those not using configfs) into a separate directory. Signed-off-by: Andrzej Pietrasiewicz Signed-off-by: Felipe Balbi

usb: gadget: serial: convert to new interface of f_obex

2013-04-03T11:43:36+00:00

f_obex is now a self-contained module. We need to teach serial.c about it. Signed-off-by: Andrzej Pietrasiewicz Signed-off-by: Kyungmin Park Signed-off-by: Felipe Balbi

usb: gadget: f_obex: convert to new function interface with backward compatibility

2013-04-03T11:43:35+00:00

Converting f_obex to the new function interface requires converting the f_obex's function code and its users. This patch converts the f_obex.c to the new function interface. The file is now compiled into a separate usb_f_obex.ko module. The old function interface is provided by means of preprocessor conditional directives. After all users are converted, the old interface can be removed. Signed-off-by: Andrzej Pietrasiewicz Signed-off-by: Kyungmin Park Signed-off-by: Felipe Balbi

usb: gadget: push tty port allocation from gadget into f_acm

2013-04-03T11:43:31+00:00

It possible to allocate the tty port number within the "instance" structure of the function and there is no need to expose this information within the gadget and therefore it is removed here. This patch converts only f_acm and all its users. The other gadgets will follow once the function is converted to the function interface.

usb: gadget: f_acm: convert to new function interface with backwards compatibility

2013-01-21T18:52:43+00:00

This patch converts f_acm into a module which uses the new function interface. It also converts one of its users that is g_serial to make use of it. The other users of it (g_nokia for instance) are still using the old include file system and should not notice the change at all. So they can be converter later independently.

usb: gadget: allocate & giveback serial ports instead hard code them

2013-01-21T18:52:43+00:00

This patch removes gserial_setup() and gserial_cleanup() and adds gserial_alloc_line() and gserial_free_line() to replace them. The initial setup of u_serial happens now on module load time. A maximum of four TTY ports can be requested which is the current limit. In theory we could extend this limit, the hard limit is the number of available endpoints. alloc_tty_driver() is now called at module init time with the max available ports. The per-line footprint here is on 32bit is 3 * size of pointer + 60 bytes (for cdevs). The remaining memory (struct gs_port) is allocated once a port is requested. With this change it is possible to load g_multi and g_serial at the same time. GS0 receives the module that is loaded first, GS1 is received by the next module and so on. With the configfs interface the port number can be exported and the device node is more predictable. Nothing changes for g_serial and friends as long as one module is used.

usb: gadget: u_serial: convert into a module

2013-01-21T18:52:42+00:00

Every user of u_serial has now to select the U_SERIAL symbol instead of including the file. There is one limition with this: ports and and gs_tty_driver are global variables in u_serial. Since all users share them, there can be only one user loaded at a time i.e. either g_serial or g_nokia. Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Felipe Balbi

usb: gadget: g_serial: split the three possible functions into three bind functions

2013-01-21T18:52:41+00:00

This patch factors out the three possible functions into three possible bind functions which are passed as an argument to usb_add_config(). This will ease the step by step converting of the individual functions to the new function registration method. Signed-off-by: Sebastian Andrzej Siewior Signed-off-by: Felipe Balbi
