2024-07-03parport: Remove parport_driver.devmodelDr. David Alan Gilbert1-1/+0
'devmodel' hasn't actually been used since: 'commit 3275158fa52a ("parport: remove use of devmodel")' and everyone now has it set to true and has been fixed up; remove the flag. (There are still comments all over about it) Signed-off-by: Dr. David Alan Gilbert <linux@treblig.org> Acked-by: Sudip Mukherjee <sudipm.mukherjee@gmail.com> Link: https://lore.kernel.org/r/20240502154823.67235-4-linux@treblig.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2024-03-18spi: lm70llp: fix links in doc and commentsKousik Sanagavarapu1-2/+2
Update links in the documentation and in-code comments which point to the datasheet and schematic. The current links don't work because National Semiconductor (which is the manufacturer of this board and lm70) has been a part of Texas Instruments since 2011 and hence http://www.national.com/ doesn't work anymore.

2024-02-08spi: bitbang: Follow renaming of SPI "master" to "controller"Uwe Kleine-König1-3/+3
In commit 8caab75fd2c2 ("spi: Generalize SPI "master" to "controller"") some functions and struct members were renamed. To not break all drivers compatibility macros were provided. To be able to remove these compatibility macros push the renaming into the SPI bitbang controller drivers.

2013-09-17spi: bitbang: Let spi_bitbang_start() take a reference to masterAxel Lin1-1/+1
Many drivers that use bitbang library have a leak on probe error paths. This is because once a spi_master_get() call succeeds, we need an additional spi_master_put() call to free the memory. Fix this issue by moving the code taking a reference to master to spi_bitbang_start(), so spi_bitbang_start() will take a reference to master on success. With this change, the caller is responsible for calling spi_bitbang_stop() to decrement the reference and spi_master_put() as counterpart of spi_alloc_master() to prevent a memory leak. So now we have below patten for drivers using bitbang library: probe: spi_alloc_master -> Init reference count to 1 spi_bitbang_start -> Increment reference count remove: spi_bitbang_stop -> Decrement reference count spi_master_put -> Decrement reference count (reference count reaches 0) Fixup all users accordingly.

2012-05-20spi: By default setup spi_masters with 1 chipselect and dynamics bus numberGrant Likely1-3/+0
Trivial simplification. Instead of requiring spi master drivers to always set the bus number (even when a dynamic number is desired), this patch modifies spi_alloc_master() to initialize num_chipselect to 1 (because there will always be at least one CS) and bus_num to -1 for dynamic allocation. This simplifies the code needed to be written for drivers. Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
2011-06-06spi: reorganize driversGrant Likely1-0/+351
Sort the SPI makefile and enforce the naming convention spi_*.c for spi drivers. This change also rolls the contents of atmel_spi.h into the .c file since there is only one user of that particular include file. v2: - Use 'spi-' prefix instead of 'spi_' to match what seems to be be the predominant pattern for subsystem prefixes. - Clean up filenames in Kconfig and header comment blocks Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Wolfram Sang <w.sang@pengutronix.de> Acked-by: Linus Walleij <linus.walleij@linaro.org>
